Climate Change

The world is warming up, with 2023 being by far the hottest year since record keeping began and 2024 shaping up to be hotter yet. But these changes only involve one or two degrees. What's the big deal?

The amount of energy required to raise the temperature of one liter of water by one degree is one kilocalorie (kcal). Scaling up, the amount of energy required for a one-degree increase in the water temperature of the Gulf of Mexico is 2,434,000,000,000,000,000 kcals. That's 25 million times more energy than released by the WW-II atomic bomb that destroyed the city of Hiroshima and killed more than 100,000 people.

So, for every one degree increase in water temperature, the Gulf of Mexico takes on 25-million atomic-bombs' worth of new energy, which is then available to fuel hurricanes and other storms. Maybe a one-degree rise in temperature is a big deal.

How publics in small-island states view climate change and international responses to it.

Proceedings of the National Academy of Sciences of the United States of America, 122(30):e2415324122.

Climate change caused by carbon pollution from the world's largest economies poses an existential threat to small-island states and territories this century. These places bear virtually no responsibility for climate change but will face sea-level rise, fresh water resource degradation, and intensified storms that will kill or dislocate exposed publics, and damage local economies. To alleviate this crisis, the global community has begun discussing who is responsible for climate mitigation and adaptation costs for those affected by climate change, in addition to continued debates around the distribution of responsibility for climate change. Missing from this analysis, however, are systematic efforts to elicit the preferences and perceptions of publics in these threatened small-island states and territories. Here, we report results from a large-sample (n [Formula: see text] 14,710) cross-national survey of publics living in climate-vulnerable states and territories, conducted in June-July 2022. By quota sampling through Facebook's ad platform, we generate survey samples at the national or territorial level for publics in 55 small-island states, territories, and subnational regions in the South Pacific, Indian Ocean, and Caribbean. We find widespread awareness and concern about the threat posed by climate change and sea-level rise, in contrast to what existing research finds in the Global North. We also find that climate-vulnerable publics believe their home governments, large polluters, and former colonial powers are all responsible for helping to manage the climate crisis, irrespective of these actors' relative carbon emissions. These findings fill an important gap by depicting climate beliefs among the communities at the frontlines of climate change.

Pre-Harvest Aflatoxin Contamination in Crops and Climate Change Factors: A European Overview.

Toxins, 17(7):.

Aflatoxin (AF) contamination of crops during the pre-harvest period is a significant global concern for food and feed safety (FFS). In Europe, climate change presents a growing threat to agricultural products by increasing the risk of AF contamination. This umbrella review evaluates the scope and quality of pre-harvest data on climate-related AF contamination in Europe, addressing key questions: What insights do researchers provide on the relationship between climate change and pre-harvest AF contamination, and what data are lacking? Which crops are the focus of current research, and where in Europe are these studies concentrated? How is the data presented, and is it standardized? We conducted an umbrella literature review, extracting relevant studies from PubMed and Scopus up to 14 October 2024. Our findings indicate that rising temperatures, droughts, and shifting rainfall patterns increasingly favor the growth of aflatoxigenic fungi and pre-harvest AF contamination in European crops, posing risks to FFS and agricultural stability. However, inconsistencies in data collection and reporting limit cross-regional comparisons and hinder the development of effective mitigation strategies. Standardizing methodologies and improving data accessibility will enhance predictive modeling, strengthen risk assessments, and support targeted adaptation efforts, providing actionable insights for policymakers and agricultural stakeholders.

Spanish Nurses' Knowledge and Perceptions of Climate Change: A Qualitative Study.

Nursing reports (Pavia, Italy), 15(7):.

Background/Objective: Nurses play a critical role in addressing climate change. They are instrumental in both mitigation and adaptation to its effects. Through care provision, education, management, policy development, and research, nurses can undertake a variety of specific actions in response to climate change. However, their perceptions of this challenge remain under-researched. This study aims to investigate Spanish nurses' knowledge of climate change and its impact on health. Methods: This is a qualitative descriptive study based on the constructivist paradigm. Purposive and snowball sampling strategies were used to recruit nurses from emergency services, geriatrics, cardiology, respiratory medicine and primary care in nine different regions of Spain. Semi-structured online interviews were conducted. Data analysis was carried out by three researchers via a three-stage inductive thematic analysis approach. Results: The sample consisted of 31 nurses, predominantly women (77.42%), with a mean age of 41 years. Seventy percent of the participants had less than 15 years of experience in the service. Four categories were identified: (i) general knowledge of climate change; (ii) knowledge of climate change and health; (iii) knowledge of actions to address climate change; and (iv) knowledge development. Overall, the nurses demonstrated awareness of the risks posed by climate change as well as actions to respond. However, barriers such as a lack of formal training and eco-anxiety affect their knowledge acquisition. Conclusions: Nurses play an important role in the response to climate change. However, more comprehensive and higher-quality educational programmes, provided by academic institutions, workplaces, and professional associations, are needed. This study was prospectively registered with the Clinical Research Ethics Committee of the Cuenca Health Area on 25 January 2022 (registration number 2021/PI3721).

Spatiotemporal trends of climate change and variability: impacts on coffee production in Abaya and Gelana Woredas, Southern Ethiopia.

Environmental monitoring and assessment, 197(8):951.

The purpose of this study was to investigate the spatiotemporal trends and variability of climate impacts on coffee production in Abaya and Gelana Woredas. To clarify reliable data from the participants, the study utilized a mixed-research approach. Combining quantitative climate analysis (Mann-Kendall test, Sen's slope, and rainfall indices) with qualitative data from surveys and interviews, this research assessed how climate variability, socioeconomic factors, and physical conditions affect coffee yield. Statistical analysis (regression and t-tests) reveals significant climate trends across the study area, including warming nighttime temperatures (Tmin), cooling daytime temperatures (Tmax), and seasonal rainfall fluctuations. Rainfall trends varied among kebeles: In Bunata, Belg (Z = 1.07) and Meher (Z = 1.03) conveyed moderate but non-significant increases, although annual rainfall showed a near-significant decline (Z = - 1.84, Q = - 0.076). In contrast, Guangawa Badiya, Giwe, and Jirme exhibited positive rainfall trends in both Belg (Z = 2.21) and Meher (Z = 2.67), while Odo Mike experienced negative rainfall trends, particularly in Meher (Q = - 0.391) and annually (Q = - 0.660). Temperature trends revealed a decrease in Tmax across all sites (Bunata - 0.61, Guangawa Badiya - 0.66, Odo Mike - 0.45, Giwe - 0.43), while Tmin increased entirely, with notable seasonal variability in Tmax. Regression modeling showed a strong correlation (R = 0.871) between climate variability, soil erosion, land size, and coffee production, explaining 83.2% of the variation in yields. Key adaptation strategies reported by farmers included intercropping (8.7%), income diversification (8.7%), cultivar selection (8.6%), agroforestry (8.5%), and integrated pest management (IPM) (7.8%). While rising Tmin, decreasing Tmax, and rainfall variability contributed to variations in coffee production in Guangawa Badiya, Giwe, and Jirme, these changes led to a decline in Bunata and Odo Mike. Coffee production has been impacted by climate change due to reducing the diurnal temperature range, hindering blooming and bean development, and making pests more vulnerable. Intense rainfall causes soil erosion and nutrient loss, while irregular rainfall impacts important development phases, resulting in flower drop and low yields. This study underscores the importance of adaptive strategies such as intercropping, agroforestry, income diversification, enhanced water management, and government support in ensuring the sustainability of coffee farming amidst ongoing climate fluctuations.

Global trends and influential factors of climate change adaptation recognition in GDELT.

Scientific reports, 15(1):26887.

Climate change adaptation recognition in developing and developed countries are crucial to tackle the environmental vulnerabilities. In this study news data from GDELT was utilized to investigate the CCA recognition (tone, concern, and scope) across different income groups of 200 countries by using monthly data from March 2015 to March 2024. Additionally, analysed socioeconomic, geographic, and demographic indicators that influence CCA recognition among 174 countries globally by using yearly data from 2016 to 2023. We employed post-hoc multiple comparison test-Dunn's test to compare CCA recognition across different income groups. We also employed OLS, and to validate OLS we also used robust econometric techniques Breusch-Pagan test for heteroskedasticity, Shapiro-Wilk test for normality of residuals, HC1 estimator for robust standard error, to ensure robustness against outliers and leverage points, robust regression techniques M estimation employed and quasi-Poisson regression for the scope model. We find that all recognition indicators median is significantly (p < 0.001) different among 4 different income level countries groups except scope indicator between low income and lower middle-income countries as well as upper middle income and high-income countries. Life expectancy causes to increase the tone and decrease the concern of CCA news significantly by 0.016 and - 0.018 respectively. Expected years of schooling has significant and positive relationship with tone and concern at coefficient 0.096, 0.025 respectively. The findings emphasize that countries with stronger socioeconomic indicators, favourable demographic profile, or reside at tropical geographic locations are more likely to prioritize and recognize climate change adaptation. The findings offer a novel approach to measuring climate change adaptation progress using news media, benefiting policymakers in enhancing sustainable development efforts.

Effects of climate change on vaccine storage and cold chain logistics: a qualitative study in Ogun State, Nigeria.

BMJ global health, 10(7):.

INTRODUCTION: Climate change remains a global challenge posing a significant risk to the vaccine cold chain system logistics. It threatens vaccine potency due to inadequate storage facilities and ineffective vaccine distribution mechanisms, which are mostly affected by unpredictable environmental conditions. In Nigeria, this situation is worsened by unreliable electric power supply, frequently interrupted alternative power sources, poorly trained cold chain personnel, and inefficient management procedures. These factors contribute to low immunisation coverage rates and high disease burdens. Hence, there is a need to assess the effect of climate change on cold chain system logistics.

METHOD: Participants were cold chain officers across vaccine cold stores in Ogun State, Southwestern Nigeria. Data were collected via a 35-item semistructured in-depth interview guide. The effect of climate change on vaccine storage and cold chain logistics efficiency in Ogun State, Nigeria, was assessed. Data were manually and thematically analysed using the constructivist variants of the grounded theory methodology. Ethical approval and participants' informed consent were obtained.

RESULT: Participants perceived that increasing ambient temperature variability constrained cold chain performance, resulting in equipment deterioration or damage. The vaccine distribution mechanism is mostly interrupted by difficult transportation systems caused by unpredictable weather changes. Policies are required around prompt replacement of damaged resources, equipment, continuous training of skilled workers, monitoring and surveillance system improvement.

CONCLUSION: Climate change significantly affected the efficiency of the cold chain system. Relevant policy implementation was highlighted as an essential step towards alleviating its effects.

Impact of Climate Change on Indoor Radon Concentrations as a Current Public Health Challenge.

Environment & health (Washington, D.C.), 3(7):705-713.

Climate change is considered to intensify radon migration into houses, increasing health risks. Energy efficiency strategies can contribute to indoor radon accumulation, particularly in the winter and summer seasons, when buildings are sealed to maintain thermal comfort. Studies in various regions of the world have shown that meteorological factors influence indoor radon concentration either directly or indirectly. Seasonal variations in radon levels have been observed, with winter concentrations exceeding summer levels by 2-5 times, while extreme weather events further impact radon exhalation. Epidemiological data indicate that the increase of indoor radon concentration by 100 Bq/m[3] raises lung cancer risk by 16%, with 35-40% of radon-related lung cancers potentially preventable through exposure reduction. Additionally, recent studies suggest a correlation between radon exposure and cardiovascular diseases, contributing to its significance for public health. Collecting meteorological data alongside indoor radon measurements and analyzing their relationship are essential for understanding such interactions as well as developing public health strategies for prevention and adaptation to future climate conditions. Based on international experience, methodological approaches to the study of the assessment of the influence of meteorological factors on the risk of radon exposure in a regional context have been formulated.

Emotional climate: a bibliometric analysis of the psychological consequences of climate change.

Frontiers in psychology, 16:1521771.

Research on climate change and its impact on individuals' emotions are receiving increasing attention. Therefore, it is crucial to evaluate the current state of this research and predict future trends to offer greater clarity for researchers and decision-makers. This study aims to analyze the co-authorship network, bibliographic coupling, and co-word analysis of scientific documents produced by researchers in the Scopus database from 2010 to 2024. This period is characterized by the emergence and conceptual consolidation of emotional responses to climate change in academic research, focusing on the psychological consequences of climate change. A total of 1,333 documents were chosen for analysis after completing the identification and screening processes. This research is applied and descriptive in terms of its scient metric approach and is conducted using co-occurrence word analysis and network analysis techniques. The collected data were analyzed using Excel, and VOS viewer software was utilized to create visual maps. The co-occurrence analysis of high-frequency terms highlighted emerging topics and critical issues related to climate change. The findings emphasize the connection between clusters related to climate change and climate justice with the core cluster of humanity and human emotions, highlighting the emerging nature of this research domain. The thematic clusters identified further emphasize the significance and novelty of climate-related emotions and the organization of related research. This review can serve as a roadmap for future research, planning, and decision-making in the area of climate change and its associated impacts.

Simulations of historical impacts of climate change and atmospheric chemistry on a northeastern U.S. forest ecosystem.

Ecological applications : a publication of the Ecological Society of America, 35(5):e70079.

Climate change, land disturbance, and atmospheric chemistry have substantially impacted northeastern hardwood forests. However, it is challenging to quantify the exacerbating or mitigating interactions among these disturbances on carbon (C), nitrogen (N), and water cycling in forest ecosystems. To evaluate these effects, we applied the PnET-CN-daily model to simulate the historical patterns of C, N, and water cycling at Harvard Forest in central Massachusetts, United States. The model was run with a reconstructed historical climate and air chemistry scenario, and results were compared with field measurements at Harvard Forest for calibration. The calibrated model was then run with a series of hypothetical scenarios to decompose the impacts of individual environmental drivers on C, N, and water cycling of the forest ecosystem. Model simulations suggest that increases in atmospheric carbon dioxide (CO2) concentrations, changes in climate, and decreases in atmospheric N deposition have contributed to historical changes in the plant C cycle. Elevated CO2 concentrations have been the dominant factor, though these effects have diminished with increasing concentrations. The combination of elevated CO2 and a warmer climate has led to increased plant growth, resulting in higher plant N storage but a decline in the soil N pool. However, elevated atmospheric N deposition has mitigated this decline in soil N and also suppressed soil decomposition. Climate has been a key driver of recent changes in the water cycle, with increased air temperatures leading to higher transpiration rates. Despite this change, soil water content at Harvard Forest remained relatively constant over the simulation period because of increasing water-use efficiency associated with increasing CO2 concentration, indicating that plant growth is not limited by water at Harvard Forest. Future investigations should use modeling approaches to project the functional responses of the forest ecosystem to the interacting effects of future climate scenarios and contrasting air quality regulations.

Heterogeneous impacts of human activities and climate change on transformed vegetation dynamics on the Qinghai-Tibet Plateau.

Journal of environmental management, 392:126575 pii:S0301-4797(25)02551-4 [Epub ahead of print].

In the context of intensifying global environmental change, elucidating vegetation dynamics and their driving mechanisms is vital for sustainable ecosystem management. The Qinghai-Tibet Plateau (QTP), a region known for its sensitivity and vulnerability, exhibits a high degree of responsiveness to climate change and human activities. The region's pronounced spatiotemporal heterogeneity renders it an optimal area for investigating vegetation changes and their driving mechanisms. However, existing research predominantly emphasizes natural factors, with insufficient systematic analysis of human activities, thereby constraining a comprehensive understanding of driving mechanisms. This study utilizes MODIS NDVI data to systematically analyze GNDVI (the average NDVI during the growing season) trends and their driving mechanisms across the QTP from 2000 to 2018, integrating natural factors (temperature, precipitation, potential evapotranspiration, snow depth, elevation, slope) and human factors (roads, population, grazing intensity) from multi-scale and vegetation-type perspectives. Results reveal a significant increasing trend in GNDVI (p < 0.05) across the QTP, with pronounced improvements in the northeast and degradation in specific regions of the southwest and southeast. From 2000 to 2018, 79.19% of QTP vegetation exhibited improvement (39.52% significantly), while 14.28% experienced degradation (2.78% significantly). During the study period, the QTP climate exhibited a warming and moistening trend, which generally benefited vegetation growth. The impacts of natural and human factors on vegetation changes vary significantly across different spatial regions. Population density and grazing intensity have obvious threshold effects on vegetation dynamics: when population density exceeds 17 pop/km[2], their effects on vegetation change rate approach marginal effects, while grazing intensity exceeds 250 SU/km[2], resulting in a significant decrease in GNDVI change rate. Notably, grazing and tourism activities near roads and lakes negatively impacted GNDVI in the southwest and southeast, partially offsetting the positive effects of climate change and contributing to degradation. Based on these findings, the study recommends establishing a long-term investment mechanism for ecosystem protection, implementing differentiated regional management strategies, and enhancing regulatory oversight of human activities. Specifically, strict controls on grazing and tourism development in ecologically sensitive areas are necessary to mitigate their impacts on fragile ecosystems. This study constructs a framework that integrates the spatiotemporal heterogeneity of natural and human factors, overcoming the limitations of traditional methods. It advances the theoretical understanding of the driving mechanisms behind vegetation dynamics in alpine ecosystems and provides a scientific foundation for formulating differentiated ecological protection policies and sustainable management strategies.

Impact of climate change on Boro rice production in Bangladesh: Evidence from time series modeling.

PloS one, 20(7):e0328699 pii:PONE-D-24-12018.

Bangladesh has three distinct rice-growing seasons: Aus, Aman, and Boro, each with its distinct climatic state. Climatic factors interacting with non-climatic factors impact seasonal rice yield. However, research hasn't yet examined how climatic and non-climatic factors (CNCFs) affect the yield of rice production during the Boro season (YBR). Therefore, this study attempted to assess the impact of CNCFs on YBR using time series modeling. Accordingly, the modeling approaches used stationarity testing and pairwise correlation analysis to verify the suitability of the CNCFs for further analysis. After that, the autoregressive distributed lag (ARDL) model, the Granger causality test, and the principal component analysis (PCA) were used to predict how the CNCFs affect YBR. The ARDL model predicted that area and temperature had a substantial positive effect on YBR in both the long- and short-run, but humidity adversely influenced YBR in the long-run and positively in the short-run. The Granger causality test revealed a unidirectional causal relationship between YBR and CNCFs, except for the climatic factor rainfall. On the other hand, the non-climatic factors area, population, energy consumption, and fertilizer consumption were positively associated with YBR and substantially contributed to PC1's (71.7%) variation. Aligning these results, this study concluded that the area, temperature, population, fertilizer consumption, and energy consumption positively impacted the YBR, while humidity negatively impacted it. These findings are crucial for ensuring Bangladesh's rice security amid climate change, guiding policymaking, and addressing future rice demand. Therefore, policymakers and stakeholders should focus on controlling greenhouse gas emissions to keep temperatures and humidity consistent, developing climate-tolerant rice cultivars, encouraging farmers to use organic fertilizer, and adapting eco-friendly technologies for sustainable rice production.

Effect of climate change on truffle (Tuber species) distribution and host plant interactions in Thailand.

Mycologia [Epub ahead of print].

Climate change is an important driver of shifts in species' geographic distributions, including those of several truffle species. Understanding these shifts is essential for effective conservation and sustainable ecosystem management. This study aimed to identify suitable habitats for three Tuber species discovered in Thailand-Tuber lannaense, T. thailandicum, and T. magnatum-and project their future distributions under climate change scenarios. Using MaxEnt modeling and presence-only occurrence data, we predicted current and future suitable habitats under two climate scenarios: SSP1-2.6 (low emissions) and SSP5-8.5 (high emissions) for the year 2050. Annual precipitation (bio12) and mean diurnal range (bio02) were the most influential environmental variables for three Tuber species and their host plants. Currently, suitable habitats for Tuber species and their host trees (Betula alnoides and Carpinus londoniana) are concentrated in mountainous areas of northern and northeastern Thailand, covering approximately 6000 km[2]. By 2050, under both SSP1-2.6 and SSP5-8.5 scenarios, the shared suitable habitat between truffles and their host plants is projected to be completely lost (100%). Carpinus londoniana is expected to lose nearly 100% of its suitable habitat under SSP1-2.6 and retain only 37 km[2] under SSP5-8.5, whereas B. alnoides shows potential for southward range expansion despite some habitat loss. These findings underscore the urgent need for targeted conservation strategies to preserve Thai Tuber species and their symbiotic hosts under changing climatic conditions.

Time to integrate climate science into kidney care planning: a 'PASIGE' to a climate change mitigation and adaptation framework.

Current opinion in nephrology and hypertension pii:00041552-990000000-00251 [Epub ahead of print].

PURPOSE OF REVIEW: Kidney diseases affect around 850 million people globally and are a growing public health burden, with high rates of associated cardiovascular mortality and no major decline in age-standardized mortality compared to other noncommunicable diseases. Climate change is an inequitable driver of kidney diseases, and climate-related disasters can disrupt access to life-sustaining kidney replacement therapies. Conversely, the care of patients with kidney diseases contributes to greenhouse gas emissions, pollution, and generates large amounts of waste.

RECENT FINDINGS: Environmentally sustainable kidney care planning is pursuing kidney care practices and innovations that minimize environmental harm while remaining patient-centered and cost-effective. An adaptation and mitigation framework (a structured approach to developing adaptation strategies, policies, and measures) to guide this is lacking.

SUMMARY: We propose the 'PASIGE' framework to guide climate science integration in kidney care planning -> Prevent: approaches to prevent kidney disease, its progression to kidney failure, and complications; Adopt: sustainable lifestyle, practices and therapies; Screen: targeted population screening for early detection and identification of kidney disease; Innovate: technology, manufacturing, procurement, energy sources and transportation; Generate: sustainably powered and produced low-impact net zero waste kidney replacement therapies resilient to climate threats; and Enhance: patient engagement, care quality, and system resiliency.

Plasticity in climate change responses.

Biological reviews of the Cambridge Philosophical Society [Epub ahead of print].

Recent research has shown that climate change can both induce and modulate the expression of plastic traits but our understanding of the role of phenotypic plasticity as an adaptive response to climate change is limited. In this review, we dissect the mechanisms and impact of phenotypic plasticity as a response to accumulating climatic pressures on the individual, species and community levels. (i) We discuss how plasticity can affect individuals, populations and community dynamics and how climate change can alter the role of plasticity. We hypothesise that some pathways to phenotypic plasticity such as irreversible and anticipatory organismal responses will be reduced under increasing climate change. (ii) We then propose an integrated conceptual framework for studying phenotypic plasticity to advance our understanding of the feedbacks between the different levels of biological organisation. (iii) By formulating as yet unaddressed research questions within and across levels of biological organisation, we aim to instigate new research on phenotypic plasticity and its role in climate change responses.

The Reflections of Global Climate Change on Wound and Ostomy Care: Awareness, Experiences, and Strategies in Nursing Practices.

International wound journal, 22(8):e70729.

This study explores nurses' perceptions of how climate change may impact wound and ostomy care, focusing on their awareness, experiences, and perceived challenges in clinical practice. It also aims to contribute to the development of sustainable care strategies in nursing. A sequential mixed-methods design was used to collect quantitative data from 95 certified wound and ostomy nurses and conduct four focus group discussions with 23 nurses. The study followed the 'Global Model for Operationalizing Sustainability in Nursing', and qualitative data were analysed using thematic analysis. Nurses demonstrated moderate-to-high awareness of climate change, with the highest score in the 'expectations' subdimension (76.78 ± 10.21). Most nurses (96.9%) believed that rising temperature and humidity would increase wound infections, and 93.8% anticipated adverse effects on skin integrity based on clinical experience. Regarding stoma complications, 94.8% identified fungal infections and 89.6% reported peristomal moisture-related damage as significant concerns. Four key themes emerged: (1) Structural factors (Cultural Bridging and Resource Evaluation), (2) Process (Nurses' Actions and Educational Activities), (3) Outcome (Observed Changes and Professional Adaptation), and (4) Future perspective (Nurses' Leadership and Sustainability). This study reveals nurses' perceptions that climate change may affect wound and ostomy care. While based on subjective reports rather than empirical data, these findings reflect common clinical concerns. Highlighting the need for climate-focused education and planning, the study calls for greater integration of environmental awareness into nursing practice to support adaptive, patient-centred care.

Airborne Microorganisms at Hellenic Atmospheric Aerosol and Climate Change Station in Helmos Mountain (Greece).

ACS earth & space chemistry, 9(7):1801-1814.

Cultural-based methods of bacteria and fungi and molecular identification of bacteria were combined with parallel continuous measurements of aerosol chemical composition, number size distribution, ice-nucleating concentration, and fluorescent particle size distribution and characteristics. Measurements took place at the Helmos Hellenic Atmospheric Aerosol and Climate Change Station (HAC)[2], Greece, during the 2021 CALISHTO campaign. The objective was to characterize the microorganism levels at the (HAC)[2] station and further investigate the associations between bioaerosols and aerosols in atmospheric processes that play a key role in the formation of ice crystals. Very low concentrations of viable, cultivable heterotrophic bacteria (4 ± 4 CFU/m[3]) were measured, whereas fast-growing fungi were not affected (182 ± 86 CFU/m[3]) by the environmental conditions at the station. The size distribution of heterotrophic bacteria was bimodal with peaks at fine (1.1-2.1 μm) and coarse size fractions (d > 7 μm), whereas airborne fungi exhibited a monomodal distribution (2.1-3.3 μm). Bacterial populations identified using 16S rRNA correlated well (r = 0.82) with the averaged concentrations of fluorescent particles (A and C channels). Strong correlations were obtained between total bacterial and particle volume concentrations of coarser fractions (>1 μm, 0.61-0.86), suggesting their strong presence in these sizes. No correlation was found with ice nuclei (INP) (r = -0.04) and low to medium negative correlations with the organics and ions (SO4 [2-], NH4 [+], NO3 [-], Cl[-]) possibly due to their relatively lower sizes. In accordance with the culture-dependent analysis, relatively low total bacterial concentrations were determined by real-time PCR, with concentrations ranging from 33.4 to 117.2 GE/m[3]. High bacterial diversity was found with 123 bacterial Operational Taxonomy Units (OTUs) classified in 10 phyla, 16 classes, 56 families, and 78 genera. Origin of the air masses was a significant driver to bacterial communities. Enrichment of specific species such as and was observed during Saharan dust episodes, while in the presence of continental air masses, characteristic species such as Rhizobium sp., Corynebacterium sp., and had higher relative abundance. Our study provides a comprehensive analysis and quantification of the varying drivers and variability in microorganisms in high-altitude site.

MaxEnt-based evaluation of climate change effects on the habitat suitability of Magnolia officinalis in China.

Frontiers in plant science, 16:1601585.

This study aimed to assess the impact of climate change on the potential distribution of the endangered medicinal plant M. officinalis in China. We sought to identify key bioclimatic variables influencing its distribution, predict current and future suitable habitats, and evaluate shifts in these habitats under different climate scenarios. We constructed a dataset comprising 405 distribution records of M. officinalis and 9 major environmental factors. The MaxEnt model, integrated with GIS software, was employed to predict the potential distribution under current (1970-2000) and future periods (2050s, 2070s, and 2090s). Model optimization was conducted using the ENMeval package to adjust regularization multiplier and feature combination parameters, ensuring enhanced predictive accuracy. The optimized MaxEnt model demonstrated high predictive precision with an AUC value of 0.917. The minimum temperature of the coldest month, mean diurnal range, and annual precipitation were identified as the key environmental variables influencing M. officinalis distribution, with contribution rates of 72.7%, 11.6%, and 4.2%, respectively. The suitable habitat was predicted to expand by 2050s under the SSP1-2.6 scenario but showed a reduction in highly suitable areas under more severe scenarios like SSP5-8.5. Centroid shift analyses indicated a northwestward migration of suitable habitats. These results from this study suggest that climate change poses significant risks to the distribution of M. officinalis, with potential shifts in both the extent and quality of suitable habitats. Our findings highlight the importance of considering climate change projections in conservation planning and underscore the need for adaptive strategies to ensure the sustainability of this medicinally valuable species. The study provides a scientific basis for the conservation and sustainable use of M. officinalis in the context of climate change.

Keeping up with climate change: have Arctic arthropods reached their phenological limits?.

Proceedings. Biological sciences, 292(2051):20250350.

Many arthropods show earlier seasonal activity with warming, but these responses cannot continue indefinitely. Identifying such phenological thresholds is crucial for understanding limits to climate tracking and species persistence, but few studies test for breakpoints that may indicate physiological or ecological constraints. Using a 28-year time series, we examined breakpoint responses to snowmelt and temperature across 15 arthropod taxa in seven plots from high-Arctic Greenland, a region experiencing pronounced warming. Our meta-analysis found breakpoint responses in two of six phenological driver and event combinations: onset and peak activity advanced with earlier snowmelt until a threshold, beyond which the relationship levelled off. A breakpoint for peak activity in response to temperature disappeared when snowmelt was included in the model, underscoring the importance of considering several environmental cues to prevent incorrect inferences about plasticity limits. Most responses showed no evidence of a breakpoint in phenological sensitivity, instead exhibiting continued tracking of cues over the study period. Our findings suggest that while many Arctic arthropods remain responsive to climate change, some may be approaching limits, potentially altering ecological interactions and vulnerability to abiotic cues. Our findings highlight the need for broader assessments of phenological thresholds to refine predictions of species responses to environmental change.

Impacts of winter climate change on northern forest understory carbon dioxide exchange determined by reindeer grazing.

The Science of the total environment, 995:180089 pii:S0048-9697(25)01729-2 [Epub ahead of print].

In northern regions, the ongoing climate change is altering snow depth with complex consequences for carbon dioxide (CO2) exchange and thus, global carbon (C) balance. In addition, ungulate grazers such as reindeer and caribou often alter plant and soil properties that may lead to modifications in the magnitudes and patterns of CO2 exchange. To understand how reindeer grazing, coupled with changes in snow depth affects CO2 exchange, we used recent snow treatments (ambient, reduced, and increased snow depth) combined with 25- and 55-year-old reindeer exclusions and the adjacent grazed areas in boreal and subarctic Scots pine forests that are main winter pastures for reindeer/caribou and cover a significant portion of boreal and subarctic landscapes. At both study sites, we measured understory net ecosystem exchange (i.e., NEE), ecosystem respiration (i.e., ER), and gross ecosystem production (i.e., GEP) over two snow-free seasons. We found that 55 years of reindeer exclusion increased C source strength by 136 % under ambient snow depth and 205 % under reduced snow depth in comparison to the grazed area with respective snow conditions. On the contrary, increased snow depth decreased C source strength inside the exclusion offsetting the difference between reindeer grazing treatments. Our results show that grazing may enhance ecosystem stability to winter climate change in comparison to long-term absence of grazing. This highlights the complexity of climate-grazer interactions in functioning of northern ecosystems which are experiencing variations in snow depth.

Shifting Heights? A 40-Year Resurvey of Alpine Marmot Distribution in Response to Climate Change.

Ecology and evolution, 15(7):e71777.

Alpine species are severely affected by climate change, with elevational range shifts being one key response of mountain species to the rapidly warming environment. The Alpine marmot (Marmota marmota) is suggested to be particularly susceptible to ongoing warming. However, it is largely unknown how climate change affected the Alpine marmot distribution in recent decades. This study examines the elevational changes in Alpine marmot distribution over the past 40 years in a Central Alps Mountain valley. Based on historical occurrence data of the year 1982, we resurveyed the marmot occurrences in the year 2022. We analysed potential distributional changes over time by fitting dynamic site-occupancy models to detect occupancy patterns, as well as marmot colonisations and site abandonments ('local extinctions' at a site) along the elevational gradient, whilst accounting for imperfect detection. Contrary to expectations, we found no evidence of upward colonisation at higher elevations or an upward shift of the lower range margin in our study, suggesting that marmots are not climate-limited at lower elevations in the investigated valley, and other factors than climate might constrain their higher elevation colonisation. Nevertheless, the marmot's elevational optimum shifted upwards by +86 m. Our results indicate that the most favourable conditions for marmots have slightly shifted higher due to warming. To better understand potential habitat contractions driven by climate change, further large-scale studies focusing on the lower range margins in warmer Alpine regions are necessary. Recognising distribution changes of species vulnerable to climate change is crucial to evaluate local extinction risks and for conserving biodiversity.

Adapting to Hypo-Salinity: Molecular Mechanisms in Giant Clams and Symbionts with Implications for Coral Reef Resilience Under Climate Change.

Environmental research pii:S0013-9351(25)01636-6 [Epub ahead of print].

Typhoon climates and extreme rainy seasons drive changes in seawater salinity and quality, threatening coral reef ecosystems. As key contributors to coral reef ecosystems, giant clams face major survival pressures from salinity fluctuations and heat waves. Understanding their salinity adaptation and recovery strategies is thus critical for the long-term conservation and sustainable management of coral reefs. Here, we integrated physiological and meta-transcriptomic analyses to investigate responses of Tridacna crocea to hypo-saline conditions (20 ppt, 27 ppt) and subsequent recovery at 34 ppt. Hypo-salinity significantly reduced growth and survival, with only 69% survival at 20 ppt, while elevated sodium-potassium pump (NKA) activity was observed, facilitating ion balance maintenance. Meta-transcriptomic analysis revealed downregulated genes related to antioxidants (GGT1), ABC transporters (ABCB11, ABCA12), and fatty acid metabolism (ACAA1), alongside upregulated genes involved in amino acid metabolism (AGXT2, ALDH4A1). Symbionts exhibited decreased photosystem II (PSII) activity, reactive oxygen species (ROS) accumulation, and expulsion. Notably, partial recovery was achieved under 27 ppt hypo-salinity, whereas 20 ppt induced irreversible damage. Collectively, T. crocea copes with hypo-saline stress through coordinated regulation of ion transport, amino acid metabolism, and symbiont functionality, with 27 ppt potentially emerging as a critical threshold for recoverable adaptation. These findings provide valuable mechanistic insights to inform coral reef conservation strategies under global climate change.

Entomopathogenic fungi: Natural biocontrol of insects, challenges under climate change, advancements and future prospects in Modern Agriculture.

Acta tropica pii:S0001-706X(25)00222-0 [Epub ahead of print].

Insects, the largest group of living entities, cause substantial damage to agriculture commodities, accounting for an estimated 35-40% losses of annual crop on global scale. While agrochemical industry is playing indespensible role in pest management, however, their overreliance has led to alarming issues such as resistance development, environmental degradation and critical disruption of natural enemies. In light of these challenges, entomopathogenic fungi (EPF) are among the most successful candidate in the race of biocontrol agents against insects. This review explores the taxonomy, biology and pathogenic mechanisms of major EPF groups-including Entomophthoromycota, Blastocladiomycota, Microsporidia, Ascomycota, Basidiomycota and Zygomycota. Additionally, the review presents an overview of mycopesticides registered and commercialized in various countries based on EPF. Finally, it outlines the impact of impending challenge of climate on EPF effectiveness and possible solutions with future research directions. This article would pave the way to enhance the knowledge, and provide an outlook for researchers, industry linked with microbial pesticides toward sustainable utilization of fungi as a fundamental component of pest management programs for sustainable crop production.

Seasonal variations in ecological environment quality across different geomorphological regions and their response mechanisms to climate change.

Scientific reports, 15(1):26385.

Understanding seasonal variations in ecological environment quality (EEQ) across diverse geomorphological regions is essential for accurately assessing ecosystem health and resilience amid climate change. However, systematic quantitative studies examining these fluctuations and their underlying climate response mechanisms remain scarce, particularly in regions with complex terrain. This study focused on Shaanxi Province, known for its diverse landforms and complex climate. Using the Google Earth Engine (GEE) platform, we systematically analyzed the spatiotemporal variations in EEQ across six geomorphic regions from 2002 to 2022. This analysis integrated the Remote Sensing Ecological Index (RSEI) with climatic factors to explore the region's response mechanisms to climate change. The results revealed the following: (1) EEQ exhibited significant regional variation, with the Daba and Qinling Mountain regions recording the highest annual average RSEI (> 0.6) and the wind-sand transition zone the lowest (< 0.25). The Guanzhong Plain, marked by intense human activity, uniquely displayed fluctuating degradation. (2) Single-season RSEI evaluations (e.g., summer) tended to overestimate EEQ in arid regions and underestimate degradation risks in humid regions. Averaging RSEI across all four seasons provided a more accurate depiction of interannual ecosystem stability. (3) EEQ responses to climate change vary significantly across regions due to the constraints imposed by water-heat balance and geomorphological characteristics. Precipitation plays a dominant role in influencing EEQ in arid regions such as the Loess Plateau, whereas temperature exerts a more significant effect in humid regions like the Daba Mountains. Human activities, particularly in the Guanzhong Plain, markedly reduce climate sensitivity, highlighting the complex interplay between natural and anthropogenic drivers. Employing an innovative "seasonal fluctuation-geomorphological heterogeneity-climate response" framework, this study reveals biases in traditional single-season assessments and delivers scientific evidence for tailored ecological restoration and climate adaptation strategies.

Nurses' educational needs regarding climate change and health by type of A descriptive cross-sectional study.

Nurse education in practice, 87:104473 pii:S1471-5953(25)00229-X [Epub ahead of print].

AIMS: To identify and compare nurses' climate-change-related health education needs based on institution type and provide foundational data for developing tailored educational programs.

BACKGROUND: Nurses are well-positioned to respond to the health effects of climate change, with roles varying by workplace settings. However, evidence on how their needs for climate-change-related health education differ by institutional context remains limited.

DESIGN: Descriptive cross-sectional study.

METHODS: An online survey of 499 nurses employed in hospitals, healthcare organisations, government/public institutions, and educational institutions was conducted in South Korea between March and May 2023. Their educational needs were analysed using Borich's Needs Assessment Formula.

RESULTS: Educational needs varied significantly by institution (F = 2.65, p = .047). Educational institutions reported the highest needs overall (4.53 ± 2.42), particularly regarding climate change mitigation and communication strategies. Hospital nurses emphasised a need for education on organisational-level strategies, while healthcare organisation nurses prioritised education on community-based monitoring and responses. Public institution nurses demonstrated the lowest educational needs and limited awareness of socially vulnerable populations. Additionally, nurses expressed greater intention to perform behaviours that are more climate-friendly than their current practices (all p < .001). Further, their educational needs were focused on immediate climate-change-related risks, while long-term or indirect effects were under-recognized.

CONCLUSION: Nurses' climate-change-related health education needs are shaped by their institutional roles and contexts. These findings highlight the necessity for role-specific and context-sensitive education beyond standardised approaches. Moreover, expanding climate-change-related nursing competency requires targeted educational strategies, institutional support, and attention to equity in both content and implementation.

Climate Change Vulnerability and Opportunities for Adaptive Capacity in Patients with Heart Failure in an Ambulatory Setting.

WMJ : official publication of the State Medical Society of Wisconsin, 124(2):106-110.

INTRODUCTION: Climate change, a global crisis, affects health through changes such as more intense and longer lasting heatwaves. Some populations are more vulnerable to such events, including those with certain medical conditions, like heart failure. This study aimed to improve understanding of heat-related vulnerabilities and opportunities to enhance adaptive capacity of patients within an ambulatory heart failure clinic.

METHODS: Heart failure clinic patients at the Clement J. Zablocki VA Medical Center in Milwaukee, Wisconsin, voluntarily completed a 25-question multiple-choice survey. We present descriptive statistics of the survey responses with count and percentage for categorical responses.

RESULTS: We found that out of 60 survey respondents, 46.55% agreed or strongly agreed they would benefit from discussing heat illness risks with their physician, and 31.58% were not aware their heat illness risk is higher on days hotter than 90 °F (32.2 °C). Several vulnerability factors were common: 70.69% follow a prescribed fluid restriction, 33.33% live alone, 20.34% lack a car with air conditioning, and 20.00% worry about their ability to pay electric bills. Notable knowledge gaps included 65% do not check forecasted temperatures, 60% do not plan activities for the coolest times of day, 43.10% lacked awareness of cooling centers, 33.33% were unsure of heat illness symptoms, and 27.12% lacked awareness of Wisconsin's Focus on Energy program.

CONCLUSIONS: A sizable portion of survey respondents indicated they would benefit from discussing their heat illness risk with their clinicians, and many underestimated their personal risk of heat illness. Additionally, multiple vulnerability factors were highly prevalent and knowledge gaps were demonstrated in this population. Our findings support adaptive capacity opportunities through heat illness education, anticipatory guidance, and increased resource awareness for patients with heart failure in an ambulatory setting.

Climate change and environmental sustainability in emergency medicine: a narrative review.

Annals of translational medicine, 13(3):31.

BACKGROUND AND OBJECTIVE: Climate change and global warming pose increasing threats to human health. These could have significant impact on healthcare systems, especially emergency services. In this narrative review, we aim to examine how climate change affects emergency attendances and operations, and to suggest strategies to reduce environmental impact through sustainability efforts.

METHODS: We performed literature search of published studies on healthcare environmental sustainability and climate change in PubMed, Embase, Google Scholar and Scopus databases using the following search terms: ("climate change" OR "global warming" OR "heatwave" OR "heat wave" OR "greenhouse effect") AND ("emergency department" OR "emergency medicine" OR "emergency, hospital services"), ("sustainability in healthcare" OR "environmental footprint" OR "carbon footprint" OR "carbon emission" OR "greenhouse gas" OR "energy us*" OR "waste") AND ("health care system" OR "health system" OR "health care" OR "healthcare" OR "health sector"). Study team members conducted independent searches of articles and any discrepancy between two members was resolved by a third independent co-investigator.

KEY CONTENT AND FINDINGS: Climate change increases incidences of both communicable and non-communicable diseases through heat-related illnesses, respiratory and infectious diseases, and physical injuries from natural disasters, leading to higher demand on emergency services. Structural damage and physical injuries from natural disasters also negatively impact healthcare resources. Vulnerable populations like the very young and elderly are extremely susceptible. Ironically, the healthcare sector contributes significantly to greenhouse gas emissions and waste production. There are challenges faced by both patients and healthcare providers in adopting sustainability in healthcare. We proposed the SCRAP strategy (Stewardship of resources, Carbon footprint reduction, Research, Advocacy for change, and Policies and education) to attain sustainable healthcare: (I) stewardship of resources; (II) carbon footprint reduction; (III) research; (IV) advocacy for change; and (V) policies and education.

CONCLUSIONS: As the frontline of most healthcare systems, emergency departments bear the brunt of resultant increased attendances. Urgent actions by the emergency medicine fraternity are needed to understand and tackle the causes and consequences of climate change in tandem with environmental sustainability efforts to mitigate these issues.

A Healthcare System's Path to Carbon Neutrality: Addressing Climate Change and Role of the Health Care.

AJPM focus, 4(4):100377.

INTRODUCTION: Anthropogenic climate change, according to the WHO, results in approximately 150,000 deaths annually through mechanisms such as heat-related mortality, altered food production, and the spread of infectious diseases. With climate change predicted to cause over half a million climate-related deaths by 2050, healthcare systems, which contribute significantly to greenhouse gas emissions, must adopt roles in environmental stewardship.

METHODS: This descriptive case study details how Kaiser Permanente, a large nonprofit organization, became the first carbon-neutral healthcare system in the country.

RESULTS: Kaiser Permanente has demonstrated environmental stewardship through initiatives such as an on-site solar program, sustainability scorecards for suppliers, and extensive partnerships with organizations to support community health and environmental building efforts. Initiatives included scaling renewable energy usage, constructing Leadership in Energy and Environmental Design-certified facilities, and reducing water use intensity led to Kaiser Permanente being the first carbon-neutral health system in the country.

CONCLUSIONS: The WHO has declared climate change as the most significant threat to human health. Kaiser Permanente's journey to carbon neutrality highlights the critical role healthcare systems play in environmental stewardship. Continued focus on climate initiatives by the healthcare sector is essential to address the growing health impacts of climate change. Kaiser Permanente's efforts provide a real-life and practical framework for achieving significant positive climate effects.

Merits of dietary patterns for China's future food security satisfying socioeconomic development and climate change adaptation.

iScience, 28(7):112859.

Food security depends on food production exceeding consumption, which are influenced, respectively, by climate change and socio-economic development. We adopted a hybrid approach for predicting features of future food security in China. Specifically, complex interactions in food security were examined using copula-based Markov Chain Monte Carlo simulation. Crop yields per unit area were simulated with a denitrification-decomposition (DNDC) model under four climate-change scenarios. A high shortage risk for soybean and lower shortage risks for maize and wheat were predicted. Compared with the extent of food security in China under other dietary patterns, the performance advantage of the Chinese dietary pattern was identified, which could mitigate crop shortage risks. The shortage risk of core crops would not be influenced greatly under the different dietary patterns. In the planning years 2025 and 2030, the shortage risks for soybean and rice would be pronounced (i.e., more than 50%), whereas those for maize and wheat would not be prominent.

Four Principles of Transformative Adaptation to Climate Change-Exacerbated Hazards in Informal Settlements.

Wiley interdisciplinary reviews. Climate change, 16(3):.

Residents of urban informal settlements are among the most at-risk of climate change-exacerbated hazards. Yet, traditional approaches to adaptation have failed to reduce risk sustainably and equitably. In contrast, transformative adaptation recognizes the inextricable nature of complex climate risk and social inequality, embedding principles of social justice in pathways to societal resilience. Its potential for impact may be greatest in informal settlements, but its application in this context introduces a new set of challenges and remains largely aspirational. To address this missed opportunity, in this focus article we provide clarity on how transformative adaptation can manifest in informal settlements. Although context-dependency precludes the formulation of specific guidelines, we identify four principles which are foundational to its deployment in these settings. Acknowledging constraints, we define levels of achievement of the principles and suggest how they might be reached in practice. Achieving transformative adaptation in informal settlements is complex, but we argue that it is already achievable and could represent a prime opportunity to accelerate the rate of adaptation to build a climate resilient society.

Naturally Occurring Epialleles and Their Roles in Response to Climate Change in Birch.

Molecular ecology [Epub ahead of print].

Epigenetics has been proposed to be an important mechanism that enables plant species to respond and adapt to environmental and climatic fluctuations and is sometimes entirely uncoupled from genetic variation. Nevertheless, the extent of this uncoupling and the contribution of epigenetics to plant responses to global climate change have not been well studied, particularly in forest trees. Here, we generated a high-quality genome assembly for Betula platyphylla, a key pioneer species in temperate and boreal forest ecosystems, one of the most sensitive areas to global warming. Extensive multi-omics sequencing of naturally white birch across the 48 provenances captured their full scope of temperate/boreal forests in Northeast China. Using a genome-wide association study (GWAS), it was shown that over 55% of differentially methylated regions (DMRs) were spontaneous, independent of genetic factors. More than 30% of the spontaneous DMRs were significantly associated with gene expression, that is, potential epialleles, which are primarily involved in metabolism and responses to abiotic stresses; and 1819 of these epialleles were significantly associated with bio-climatic variables (i.e., climatic epialleles, cEpialleles). Integrating these cEpialleles into a gradient modelling framework revealed that the natural populations of Asian white birch at high altitude/latitude might be most vulnerable to future climates. Our findings highlight the importance of integrating epigenomic and climatic data sets to forecast the adaptive capacity of a key forest species to rapid climate change.

Who's Interested in Global Warming?.

Scandinavian journal of psychology [Epub ahead of print].

We report on a study of the correlates of attitude to global warming (GW). We build on prior research on the role of demographic variables, personality, and political orientation in predicting attitude to GW. We argue dispositional optimism should increase willingness to treat GW seriously, via its impact on active coping behaviors and reducing cognitive avoidance in the face of anxiety, and that there should be an interactive effect of optimism with political orientation. We draw on an existing data set (N = 819) of adult respondents. We use correlation and regression analysis to examine the association between demographic variables, personality traits, optimism, political orientation and GW attitude. We use moderated regression to test for an interactive effect between political orientation and optimism on GW attitude. We find a significant inverse association between (more right-wing) political orientation and GW attitude, and a positive association between education and GW attitude. We find personality effects, the strongest of which is an inverse association between Competitiveness and GW attitude. As hypothesized, we find that optimism is positively associated with GW attitude and that this association is stronger for more right-wing political orientation. We draw conclusions for the efficacy of approaches to communicating about climate change to different groups. We consider limitations of the research and implications for future research.

Exploring the impact of nature connectedness on Chinese adolescents' climate change awareness and the mediating role of geographical synthetic thinking.

Scientific reports, 15(1):26351.

In the context of global efforts to address the climate crisis, enhancing adolescents' climate change awareness stands as a critical measure. Given the pivotal role of geography education in fostering environmental responsibility and understanding the interplay between nature and human society, this study explores how nature connectedness among adolescents influences their climate change awareness, with a specific focus on the mediating effect of geographical synthetic thinking. Based on a survey of 1,338 Chinese adolescents, the findings reveal that fostering nature connectedness significantly enhances climate change awareness. Furthermore, the mediating role of geographical synthetic thinking sheds light on the underlying mechanisms of this relationship. The research findings further highlight the value of geography education in promoting climate change awareness, offering novel implications for advancing climate change education.

Relationship between sustainable food literacy, organic food consumption and climate change awareness and worry in Türkiye.

BMC public health, 25(1):2491.

OBJECTIVE: The rapid increase in population, industrialization, and the rise in fossil fuel consumption have led to issues such as the depletion of natural resources, loss of biodiversity, and climate change, bringing the concept of sustainability to the forefront. This study aimed to examine the relationship between sustainable food literacy, organic food consumption, climate change awareness and worry.

METHODS: This cross-sectional study included 1660 adults aged 18-65 years. Data were collected via a web-based survey that included demographic information, self-reported anthropometric measurements, and validated scales: Climate Change Awareness Scale, Climate Change Worry Scale, Organic Food Consumption Scale, and Sustainable Food Literacy Scale.

RESULTS: The mean age of the participants was 29.3 ± 12.07 years. A strong positive relationship was observed between the total score of the Climate Change Awareness Scale and the scores of the Climate Change Worry Scale, Organic Food Consumption Scale, and Sustainable Food Literacy Scale (r = 0.230, p < 0.001; r = 0.149, p < 0.001; r = 0.173, p < 0.001, respectively). According to linear regression analysis, it was determined that gender, education level, Climate Change Awareness Scale total score, Climate Change Worry Scale score, and Sustainable Food Literacy Scale score were correlated with the Organic Food Consumption Scale score (R²=0.527; p < 0.001). On the other hand, it was determined that gender, education level, income status, Climate Change Awareness Scale total score, Climate Change Anxiety Scale score and Organic Food Consumption Scale score were correlated with the Sustainable Food Literacy Scale score (R²=0.505; p < 0.001). It was determined that Climate Change Anxiety Scale score and the Sustainable Food Literacy Scale score were associated with the Climate Change Awareness Scale total score (R²=0.246; p < 0.001). In addition, it was determined that gender, marital status, Climate Change Awareness Scale total score, and Sustainable Food Literacy Scale score were associated with the Climate Change Worry Scale score (R²=0.286; p < 0.001).

CONCLUSIONS: As a result, to combat global climate change, it is necessary to conduct further research in this field by considering these relationships, to identify and improve the factors influencing sustainable behaviors, to promote organic food consumption, and to assess awareness and anxiety regarding climate change.

Public perception and attitudes towards health care, anesthesia, and climate change: a survey study.

Canadian journal of anaesthesia = Journal canadien d'anesthesie [Epub ahead of print].

PURPOSE: Hospitals and especially operating rooms are known to have a significant carbon footprint. With health care moving towards patient-centered care, we sought to investigate the perception and attitudes of patients and/or their family members towards health care, anesthesia, and climate change, and its influence on their care choices. We hypothesized that < 30% of our study population were aware of health care's significant contributions to climate change.

METHOD: Following research ethics board approval and participants' consent, we conducted interviews using a questionnaire that queried participating patients' perceptions on climate change and their knowledge of health care's environmental impact. To determine if such perceptions influenced their care choices, we proposed two different anesthesia care choices with different environmental impacts for a hypothetical surgical scenario. Lastly, we sought to determine participants' interest in further information on the topic. We analyzed the survey responses for associations between participants' perceptions of climate change and on health care's carbon footprint with variables pertaining to participant characteristics, their anesthesia care choices, and interest in further knowledge.

RESULTS: Overall, 320 participants completed the survey, of whom 32% acknowledged health care "greatly contributes to climate change." Nevertheless, perceptions did not translate to care choices as many participants still opted for the choice deemed to have a greater environmental impact (45%). A strong association existed between perception of health care's environmental impact and level of education (P = 0.02).

CONCLUSION: Public perception of health care's contribution to climate change was poor albeit higher than anticipated. Participants' perceptions of climate change or health care's impact on the environment did not completely translate into choosing a less carbon-intensive anesthesia care modality for their own care. Efforts to inform patients regarding the environmental impact of anesthetic choices may have minimal impact on individual care choices.

Assessing climate change impacts on flood risk in the Yeongsan River Basin, South Korea.

Scientific reports, 15(1):26113.

Flood risk prediction is critical for adaptation to the forecast frequency of extreme weather events. As South Korea experiences events that cause widespread flood damage, we conducted a flood risk assessment by employing global climate models and a hydrological model of the Yeongsan River Basin. Using shared socioeconomic pathway scenario data from the soil and water assessment tool, we simulated daily streamflow and reservoir outflow data for each sub-basin, modeling baseline, mid-century, and end-century scenarios. Four flood indices (duration, magnitude, probability, and frequency) were used for estimating flood risk. The spatial distribution of flood risk projected higher risks in most sub-basins for the mid- and end-century scenarios with an increase of flood amount to about 65% in the future. Adaptive strategies were required to address the risks of both flash floods and longer-term flooding. The study facilitates prioritizing flood risk regions for implementing effective preventive measures and efficient flood management.

Linking individual animal behavior to species range shifts under climate change.

Trends in ecology & evolution pii:S0169-5347(25)00158-2 [Epub ahead of print].

Climate change has led animal species to shift their ranges to greater elevations, latitudes, and depths, tracking their preferred abiotic niche. However, there is extensive variation in these shifts, and some species have not shifted their ranges at all. Some of this variation arises because species' distributions not only align with the abiotic environment but are also shaped by biotic factors and movement. Through facilitating rapid adaptive responses to climate-mediated changes to abiotic, biotic, and movement factors, behavioral plasticity allows populations to survive environmental change to persist in place, while also enabling successful establishment in novel habitats when shifting in space.

Maintaining Resilience and Well-Being in the Era of Climate Change: Protocol of an Acceptability and Feasibility Pilot of the Bee Well Program for Treating Eco-Anxiety in Rural Children Exposed to Natural Hazards.

JMIR research protocols, 14:e69005 pii:v14i1e69005.

BACKGROUND: The effects of climate change on mental health are becoming widely recognized. Mental health can be impacted through direct and indirect exposure to natural hazards, as well as through the overarching awareness of climate change and the resultant environmental decline-the latter is termed eco-anxiety. Exposure to natural hazards also increases eco-anxiety, further compounding mental health impacts. Young people are especially vulnerable to the mental health impacts of climate change and have higher rates of eco-anxiety than other age groups. Those in rural areas are also more likely to be impacted by natural hazards, further underscoring the need to support this population. To date, there remains scant evidence regarding how to support young people with eco-anxiety, and few interventions, especially for children, have been evaluated. There is a need for further research to inform treatment for young people for climate change-related distress.

OBJECTIVE: This study pilots a novel group-based mental health and resilience intervention in relation to eco-anxiety. Specifically, this project aims to explore the acceptability, feasibility, and clinical utility of a group-based eco-anxiety intervention.

METHODS: The project is an exploratory pilot assessing the acceptability, feasibility, and clinical utility of a group-based intervention using a pre-post design with a single group. A minimum sample of 12 children aged 10-14 years located in a rural area and with exposure to at least one natural hazard will be enrolled in this study. In order to assess clinical utility, changes from preintervention to postintervention in distress, resilience, and climate emotions will be assessed. To do so, children will complete measures of psychological distress (subjective units of distress, Depression Anxiety Stress Scale-21-youth version), climate emotions, and resilience (Resilience Scale for Children-10) before and after the intervention. Acceptability will be assessed post intervention through a series of Likert scale and open-ended questions. Feasibility will be assessed through enrollment and the proportion of participants completing the full intervention. Eligible children will take part in a novel 5-module group-based intervention designed to build resilience, promote nature connectedness, build social support, and foster meaning-focused coping.

RESULTS: This study has received ethics board approval by the University of New England's Human Research Ethics Committee (HE23-080). This study will be conducted from late 2024 to 2025. As of March 2025, 28 children have been enrolled in the study.

CONCLUSIONS: Rural children and young people are an especially vulnerable population for the mental health impacts of climate change. To date, the evidence base for interventions for treating eco-anxiety remains sparse, especially for young people and children who typically have higher rates of eco-anxiety than older age groups. This study will provide preliminary evidence of a group-based treatment for children and adolescents experiencing eco-anxiety that can inform practitioners.

A psychological network approach to engagement with climate change in Dutch youth.

Acta psychologica, 258:105290 pii:S0001-6918(25)00603-1 [Epub ahead of print].

Whether youths engage with climate change is determined by a variety of cognitive, emotional and behavioral constructs, such as their interest in the topic, perceived distance to climate change, their perceived self-efficacy concerning climate change mitigation as well as (self-reported) pro-environmental behavior. In the current study, we employed a psychometric network approach to map the relationships between psychological climate change engagement constructs of 436 Dutch youth (16- to 24-year-olds), including a measure of actual behavioral engagement (information seeking). Communities of positively related constructs formed within the network - meaning that someone experiencing higher levels of self-efficacy is also more hopeful in the light of climate change. Climate change knowledge only played a peripheral role in the network. Self-efficacy was directly linked with information seeking and was the most central (i.e., influential) construct, linking the different communities. This makes self-efficacy a potential target for interventions aimed at stimulating behavioral climate change engagement.

Dynamic assessment of biochar soil carbon climate change impacts.

The Science of the total environment, 995:180058 pii:S0048-9697(25)01698-5 [Epub ahead of print].

Biochar is receiving increasing political attention as a scalable and relevant climate change mitigation tool. With this growing focus comes a growing need for more accurate assessments of biochar climate change impact potentials. The mechanism of biochar soil carbon climate change mitigation is the time offsetting of emissions through decreased soil carbon decay. Therefore, temporally dynamic modelling is necessary to accurately assess these impacts. In this study, the 100-year evolution of soil carbon following soil application of biochar, residual straw and agricultural biogas digestate is modelled considering uncertainty related to biochar stability and environmental variability. From soil carbon modelling, dynamic climate change impacts are determined for biochar, straw and digestate per unit carbon added to soil for use in life cycle assessment. The developed methods are showcased in impact assessments of biochar at two levels of systems perspective. Results show that the developed dynamic modelling methods improve the accuracy of soil carbon climate change impact assessment. By disregarding short-term soil carbon storage, static modelling underestimates the impacts of non-pyrolyzed biomass soil carbon by a factor of two to three. Biochar is shown to provide a significant net climate benefit through increased soil carbon storage. In a large-scale implementation scenario, it is shown that biochar can contribute beneficially towards the Paris agreement 2100 temperature target, but also that national emissions accounting methods and short-term political climate targets can become a barrier for political incentives to realize the climate change benefits of biochar.

Shifting spring ephemeral pollination windows under climate change - a three-body problem.

The New phytologist [Epub ahead of print].

Potential and realized climate change-driven phenological mismatches have been reported across a variety of pairwise species' interactions. However, species often engage in more than one type of temporally structured interaction - therefore, the consequences of phenological shifts must be evaluated in this context. Synthesizing data from natural history collections, community science initiatives, and remote-sensing platforms, we analyzed the phenology of the flowering of an understory spring ephemeral species, the emergence of its specialist pollinator, and the closure of the canopy above. We determined how variation in phenological responses to climate across these interacting guilds impacts the potential pollination window of the spring ephemerals. We demonstrate that phenological responses to climate change can vary greatly among the three guilds across their interacting range. The potential pollination window was predicted to undergo divergent shifts among ecoregions across the landscape in the near future, which can impact the fitness and reproductive success of both flowers and pollinators. Our study represents a first step toward integrating phenological knowledge across multiple interacting guilds. Expanding such efforts will be critical to improving our ability to predict how ecosystems, communities, and the ecological interactions therein will be impacted by global change.

Seagrass ecosystems in peril: Climate change threatens blue carbon storage and ecosystem services.

iScience, 28(7):112909.

Climate change threatens seagrass ecosystems, which are vital for blue carbon sequestration and associated co-benefits. Our study on Hainan Island in the South China Sea assessed climate impacts on seagrass habitats using ensemble modeling under two scenarios (RCP4.5 and RCP8.5) for 2050 and 2100. We found the current seagrass carbon stock is approximately 1.194 Tg, but projections show habitat suitability could decrease by up to 74.78% by 2100 under the severe scenario, potentially causing economic losses of $1.02-1.27 billion. While seagrass restoration requires initial investment, it offers substantial long-term climate benefits. Our analysis indicates seagrasses may migrate toward higher latitudes due to climate change, though new habitats could emerge along Hainan's southern coast by 2100. These findings emphasize the urgency of conservation and restoration efforts to safeguard seagrass ecosystems and their vital role in climate change mitigation strategies.

Global warming risks dehydrating and inflaming human airways.

Communications earth & environment, 6(1):.

Global warming increases water evaporation rates from planetary ecosystems. Here, we show that evaporation rates encountered during human breathing in dehydrating atmospheres promotes airway inflammation and potentially exacerbates lung diseases. Continuum mathematical analysis predicts that water evaporation thins airway mucus layers and compresses epithelial cells during tidal breathing. Experiments using human tracheal-bronchial cells confirm that exposure to air with progressive degrees of dryness (relative humidities of 95%, 60% and 30% at 37°C) causes the mucus layer to progressively thin (by 5%, 35%, and 58%). Associated compression of epithelial cells elevates secretion of inflammatory cytokines (TNF-α , IL-33, and IL-6). Exposing mice with a muco-inflammatory phenotype to intermittent dry air for 7 days results in histopathological changes and alteration of inflammatory infiltrates. Together with climate model simulations, these findings suggest that most of the United States will be at elevated risk of airway inflammation by the latter half of this century.

Holocene climate change recorded of Milanggouwan and Dishaogouwan sedimentary profile in the Salawusu River Basin.

Scientific reports, 15(1):25958.

This paper investigates the MGS1 sedimentary profile and the DGS1 sedimentary profile (37° 41'-37° 45' N, 108° 29'-108° 35' E) to analyze the mean particle size (Mz), oxides and trace elements, chemical index of alteration (CIA), scanning electron microscopy (SEM) images, and their correlation with regional Holocene climate fluctuations in the Salawusu River Basin. The results demonstrate that the chemical element variations in MGS1 and DGS1 align with the aeolian dune facies, lacustrine facies, and paleosol. The climatic information reflected by oxides like SiO2 and trace elements like Sr shows temporal and spatial consistency, suggesting an obvious response to desert monsoon climate changes in northern China. The Holocene climate in the Salawusu River Basin is characterized by four periods of fluctuation: early Holocene warming (11,020-10,290 Yr BP), Holocene maximum warmth (10,290-6590 Yr BP), Holocene warm-cold transition (6590-3760 Yr BP), and Holocene cold-dry climate instability (3760-0 Yr BP).

Comparative impacts of climate change and human activities on spatiotemporal changes of bare land in the Turpan-Hami Basin (1985-2020).

Scientific reports, 15(1):25948.

Desertification in arid regions poses significant threats to ecological security, necessitating detailed investigations into its spatiotemporal dynamics and driving mechanisms. This study examines the evolution of bare land in the Turpan-Hami Basin from 1985 to 2020 using land use/cover data, integrated with climatic variables (potential evapotranspiration, wetness index), human footprint indices, and soil organic carbon (SOC) content. Our results revealed that (1) from 1985 to 2020, bare land area decreased by 16,251 km[2] (- 6.4%), with notable regional heterogeneity: reductions occurred in the northern (NB) and southern basins (SB) (8.06-8.23% of change rates), while the Tianshan Mountains (TM) experienced a 28.50% increase; (2) 81.04% of bare land transitioned to grassland, followed by shrubland (13.78%), with shrubland conversion accelerating post-2000 (peaking at 14.09%). (3) Climate change affected the trend for bare land, whereas human activities exhibited divergent impacts which was intensifying bare land expansion in NB and TM through overgrazing, but suppressing expansion in SB through oasis reclamation. Moreover, the soil organic carbon influenced bare land stability, though its effects were modulated by climate-human interactions. This study demonstrates the synergistic interactions between climate change and human activities in driving bare land dynamics. Future desertification management requires region-specific strategies that integrate climate change projections.

Advanced hydrological assessment with SWAT+ under climate change: An integrated framework over large climate-sensitive and reservoir-regulated watershed.

The Science of the total environment, 994:180062 pii:S0048-9697(25)01702-4 [Epub ahead of print].

Quantifying streamflow dynamics under changing hydroclimatic conditions is essential for effective water resources planning, particularly in reservoir-regulated basins. This study, for the first time, develops a dynamic reservoir-streamflow modelling framework to simulate historical and future streamflow in the Mahanadi River Basin (MRB), a large, climate-sensitive basin in India. The framework is driven by the latest version of the Soil and Water Assessment Tool Plus (SWAT+), with a dynamic reservoir operation module, and the CLIMEA-BCUD dataset (Climate Change for East Asia with Bias-Corrected UNet), a high-fidelity product derived from an ensemble of 19 CMIP6 GCMs. A thorough evaluation against benchmark station-level observations indicates a high degree of closeness of CLIMEA-BCUD in capturing historical precipitation and temperature variability (CC > 0.9, NSE > 0.85). A seasonal shift in monsoon rainfall patterns is observed in the future climate scenarios, with the peak moving from July to August. Additionally, more frequent moderate rainfall and prolonged wet spells are expected, intensifying flood potential. SWAT+ simulations developed for SSP2-4.5 and SSP5-8.5 scenarios project up to 30.7 % and 52.3 % rise in streamflow for about 15.2 % and 28.5 % rise in precipitation, respectively, during the far-future. Our observations also indicate that wet season flows (June-November) may increase by up to 61.3 %, while dry season flows (December-May) may decline by 34.1 % due to elevated evapotranspiration. This study presents a scalable framework to enhance streamflow resilience in regulated, climate-sensitive basins and offers critical insights for understanding hydrological responses and enabling climate-resilient water management.

Impacts of human activities on vegetation dynamics amid climate change: A case study of the Hanjiang River Basin (China).

Journal of environmental management, 391:126581 pii:S0301-4797(25)02557-5 [Epub ahead of print].

Investigating the interplay between vegetation, climate change, and anthropogenic activities is essential for advancing global environmental research. The Hanjiang River Basin exhibits heightened susceptibility to anthropogenic influences that markedly alter its ecological dynamics. This study utilized MODIS NDVI data (2002-2022) alongside precipitation and temperature data to evaluate the distinct impacts of climatic factors and anthropogenic activities on NDVI variability by applying Pearson correlation and residual analysis. Additionally, the partial derivatives method quantified the individual contributions of each factor to NDVI changes. The research revealed that NDVI exhibited a consistent upward trend, particularly in the western regions, while urbanization in the mid-to-lower reaches, especially around Wuhan city, led to vegetation degradation. Mean NDVI increased from 0.8067 to 0.8467 between 2002 and 2022, corresponding to an average rate of 0.002 NDVI units per year. Temperature emerged as the primary climatic driver of NDVI fluctuations, with precipitation impacts varying across the basin. However, human activities were found to exert a more significant influence on vegetation dynamics than climatic factors. Hurst index analysis predicted a positive future trend in 58.11 % of the basin, but 41.89 % may face further degradation. This study highlights the dual effects of anthropogenic activities on vegetation under climate change, providing theoretical insights for robust ecological management and sustainable development strategies within the study area.

Integrating Microbial Community Data Into an Ecosystem-Scale Model to Predict Litter Decomposition in the Face of Climate Change.

Global change biology, 31(7):e70352.

Litter decomposition is an important ecosystem process and global carbon flux that has been shown to be controlled by climate, litter quality, and microbial communities. Process-based ecosystem models are used to predict responses of litter decomposition to climate change. While these models represent climate and litter quality effects on litter decomposition, they have yet to integrate empirical microbial community data into their parameterizations for predicting litter decomposition. To fill this gap, our research used a comprehensive leaf litterbag decomposition experiment at 10 temperate forest U.S. National Ecological Observatory Network (NEON) sites to calibrate (7 sites) and validate (3 sites) the MIcrobial-MIneral Carbon Stabilization (MIMICS) model. MIMICS was calibrated to empirical decomposition rates and to their empirical drivers, including the microbial community (represented as the copiotroph-to-oligotroph ratio). We calibrate to empirical drivers, rather than solely rates or pool sizes, to improve the underlying drivers of modeled leaf litter decomposition. We then validated the calibrated model and evaluated the effects of calibration under climate change using the SSP 3-7.0 climate change scenario. We find that incorporating empirical drivers of litter decomposition provides similar, and sometimes better (in terms of goodness-of-fit metrics), predictions of leaf litter decomposition but with different underlying ecological dynamics. For some sites, calibration also increased climate change-induced leaf litter mass loss by up to 5%, with implications for carbon cycle-climate feedbacks. Our work also provides an example for integrating data on the relative abundance of bacterial functional groups into an ecosystem model using a novel calibration method to bridge empiricism and process-based modeling, answering a call for the use of empirical microbial community data in process-based ecosystem models. We highlight that incorporating mechanistic information into models, as done in this study, is important for improving confidence in model projections of ecological processes like litter decomposition under climate change.

Stakeholder analysis in climate change health adaptation in Iran: social network analysis.

Journal of environmental health science & engineering, 23(2):22.

PURPOSE: This study aimed to determine the roles and responsibilities of stakeholders in decision-making, research, policy-making, and the implementation of an adaptation plan, with a comprehensive view of their positions, influence, and power.

METHODS: This descriptive-analytical research was conducted using a social network analysis approach. The opinions of 25 university professors, experts, and executives were gathered through a questionnaire utilizing a Likert scale, selected via purposive and snowball sampling. Data analysis and graph design were performed using Microsoft Excel and Gephi software (version 0.9.2). Stakeholder interaction patterns were identified using the Force Atlas 2 algorithm and graph theory concepts.

RESULTS: The network comprised 37 nodes, 3 clusters, and 63 edges. It closely resembled a complete graph, with a density of 0.971. Within the network of stakeholders, the Intergovernmental Panel on Climate Change emerged as the most active participant, exhibiting relatively strong external interactions with other stakeholders. In contrast, the Department of Environmental Protection and the Ministry of Health and Medical Education showed relatively weak and very weak external interactions, respectively.

CONCLUSION: Given the conflicting interests between industrial sectors and the health sector, it appears that the Ministry of Health and Medical Education should enhance its power and influence over other stakeholders. Additionally, involving representatives from the health sector in policy reviews and stakeholder consultations may help bridge the gap between health and other sectors regarding climate change issues.

Rewetting drained forested peatlands: A cornerstone of Sweden's climate change mitigation strategy.

Ambio [Epub ahead of print].

Peatland rewetting has developed into a key strategy to limit greenhouse gas (GHG) emissions, enhance carbon uptake, and restore biodiversity. With an increasing political ambition to enhance rewetting across many countries, there is a risk of prioritizing peatlands that are most readily available before the ones that result in the largest climate and biodiversity benefits. Based on the best current understanding, we provide a conceptual model of the climate impact and discuss some key steps of progress needed. We focus on Swedish conditions, but also use relevant studies from similar hydroclimatic conditions elsewhere. We argue that the large political interest and investments now made to rewet large areas of peatlands, in combinations with the many unknowns, make it more important than ever to start new rewetting research studies that includes various key aspects of GHG, hydrology, and biodiversity along large climate, land-use history, and nutrient gradients.

NDVI based vegetation dynamics and responses to climate change and human activities at Xinjiang from 2001 to 2020.

Scientific reports, 15(1):25848.

As global climate change intensifies and human activity increases, the frequency and severity of droughts worldwide are escalating. In response, the Chinese government has implemented extensive afforestation efforts to combat ecological degradation, but their effectiveness in arid areas needs further evaluation. This study employed the Mann-Kendall (MK) trend test and correlation analysis to investigate the temporal and spatial dynamics of vegetation changes, as well as their association with climate factors, in Xinjiang from 2001 to 2020. The analysis was based on the normalized vegetation index (NDVI) and high-resolution meteorological data. Additionally, we assessed the potential effects of human activities on NDVI dynamics through residual analysis. The results indicate significant temporal and spatial heterogeneity in NDVI change in Xinjiang, with varying growth rates across different seasons and regions. While some regions showed a downward trend, a significant overall increase in NDVI was observed. High NDVI values were primarily found in mountainous regions, whereas low values were more common in plains. Temperature was the main climate factor influencing interannual, spring, and autumn NDVI changes, while precipitation was primarily associated with vegetation growth during summer and winter. Residual analysis revealed that human activities had contributed to vegetation degradation in certain regions, primarily in northern Xinjiang. However, overall vegetation change showed a positive trend, with human activities accounting for over 60% to NDVI changes across different periods and regions. These findings highlight the importance of considering the impact of human activities when developing vegetation restoration and conservation strategies to ensure the long-term sustainability of ecosystems.

Temperature-Related Hospitalization Burden under Climate Change.

Nature pii:10.1038/s41586-025-09352-w [Epub ahead of print].

Climate change has significantly increased adverse effects on human health, and economic growth[1-3]. However, few studies have differentiated the impacts of extreme temperatures at the city level, and analysed the future implications for human health under various climate change scenarios.[4-6] Here, data on historical relationship among six kinds of climate-sensitive diseases (CSD) hospitalizations and temperatures across 301 cities (over 90% of all cities) and more than 7,000 hospitals in China are leveraged, and a nonlinear distributed lag model is used. This study projects hospitalization risks associated with extreme temperatures through to the year 2100 and develops the Hospitalization Burden Economic Index to assess the burden under three carbon emission scenarios in cities. Five dimensions including spatial distribution, disease categories, population age groups, future time horizons, and carbon emission development pathways have been evaluated. Historical data specifically indicate more temperature-related risks among the CSDs in northwestern and southwestern China. Notably, gestation-related disease risk is associated with increased vulnerability to extreme heat in specific regions. The projections reveal that, under current thermal conditions with no adaptations, the excess hospitalizations from extreme heat will reach 5.1 million people by 2100 under the high emission scenario.These findings highlight the need for targeted climate change mitigation strategies to reduce uneven climate-related hospitalization risks and economic burdens while accounting for differences in city geography, extreme temperatures, population groups and carbon emission development pathways.

Comparative analysis of asphalt and geomembrane sealing systems for sustainable uranium pile remediation: Insights from hydrological modeling under climate change.

Journal of hazardous materials, 496:139183 pii:S0304-3894(25)02099-0 [Epub ahead of print].

Uranium ore mining heaps in Saxony and Thuringia (Germany) have been primarily covered with mineral layers as part of remediation efforts. However, aging processes in these covers-driven by climatic factors, vegetation, and root penetration-can create cracks and pathways that increase radon emissions. In residential areas, elevated radon levels may exceed the guideline values set by radiation protection regulations. While asphalt seals and geomembranes are well-established as effective long-term solutions for creating convection-tight surface systems in landfill applications, their use has rarely been considered for uranium legacy sites. This study evaluates the long-term water balance and sealing effectiveness of asphalt and geomembranes at historical uranium mining site under future climate scenarios. Using the Hydrologic Evaluation of Landfill Performance (HELP) model, we simulated water behavior and potential infiltration rates across several sealing configurations, considering current and future climate projections. Our findings reveal that both sealing systems effectively minimize infiltration, surface runoff, and seepage, with negligible infiltration even under worst-case scenarios. The results underscore the robust environmental protection offered by these systems in mitigating radon emission and ensuring long-term environmental safety. This study contributes critical insights for selecting appropriate sealing systems in mining site remediation, offering sustainable solutions that address water conservation, climate resilience, and cleaner production principles.

A review of the occurrence, antimicrobial resistance and health implications of Vibrio cholerae in African aquatic milieus, and the analysis of the impact of climate change on cholera outbreaks in Southern Africa.

The Science of the total environment, 994:180057 pii:S0048-9697(25)01697-3 [Epub ahead of print].

Vibrio cholerae, especially serogroups O1 and O139, represent a serious public health risk in many African nations as it causes cholera, which accounts for numerous epidemics and significant mortality within the continent. The World Health Organization (WHO) reported approximately 86,330 cholera deaths in Africa between 1995 and 2016, with poor water quality usually being the most frequent transmission route. Like with many other infectious diseases, climate change is increasingly recognized as an influential factor contributing to these cholera outbreaks, notably affecting the distribution, frequency and seasonality of V. cholerae. However, evidence linking temperature variability and precipitation to cholera outbreaks is moderate, requiring more research to establish stronger connections between climate change and cholera incidence. This review reports the occurrence, antimicrobial resistance and health implications of V. cholerae in aquatic milieus in Africa. Furthermore, the review uses publicly available data to statistically infer any potential link between cholera outbreaks and climate change (rainfall and temperature) with Southern Africa as a case study. It concludes by suggesting potential solutions for the prevention of future outbreaks within the region.

Climate change mitigation and synergies with primary cancer prevention in Europe: time to implement opportunities.

Journal of the National Cancer Institute pii:8203477 [Epub ahead of print].

Ten years after the adoption of the treaty on climate change by the 21st Conference of the Parties (COP21) in Paris, implementation of climate change mitigation measures remains a priority and urgency. Same priority and urgency apply to cancer prevention to counter the trend of an increasing cancer burden. The burden is projected to increase worldwide more than 50% during the next 20-25 years, ruling out treatment as the only countermeasure due to overburdened health systems. While the effects of global warming on the cancer burden are highly speculative, synergies of remedial action on climate change and increasing cancer rates have clearer evidence base. These synergies are described for the situation in Europe using the 4th edition of the European Code against Cancer (ECAC) for recommendations on cancer prevention and the 2030 breakthroughs for climate change mitigation by the United Nations Climate Change (UNCC) High-Level Champions Climate Solutions Implementation Roadmap. ECAC's recommendations on healthy body weight, physical activity, reduced meat consumption, avoiding too much sun, and reducing air pollution, align well with many of the 2030 breakthrough recommendations. Those are on healthier food including limiting meat consumption, on cleaner air through reducing transportation and through in general reducing carbon, methane and other emissions, and on mitigating temperature rise. Campaigns combining climate change mitigation with cancer prevention have the potential to encourage individuals, community groups, and policy-makers to empower the implementation of measures to counter global warming and towards a world where fewer people get cancer.

Extreme Heat Hits Different Under Climate Change: A Review of Risks and Legal Protections for Agricultural Workers in Canada and the United States.

Current environmental health reports, 12(1):25.

PURPOSE OF REVIEW: This paper synthesizes recent research about the impacts of climate change on farmworkers and analyzes notable features of existing laws in Canada and the United States designed to protect farmworkers from extreme heat.

RECENT FINDINGS: Extreme heat presents a widespread and urgent threat to the wellbeing and productivity of agricultural workers globally, and it amplifies occupational exposures such as pesticides and air pollution. Other extreme weather events such as wildfires and flooding also heighten risks to agricultural workers. In Canada and the United States, laws designed to protect workers from extreme heat are limited to a handful of jurisdictions. Laws that regulate working in extreme heat are one tool to protect farmworkers from climate change. Important features of these laws include trigger temperatures at which extreme heat measures are required and heat-specific measures related to hydration, acclimatization and administrative controls. More research is needed to better understand how effective these laws are at protecting workers on the ground.

Maritime Antarctica has a milder climate than the Antarctic continent and is naturally more sensitive to rising global temperature. Therefore, it is necessary to understand the soils, including those with permafrost, as well as the relief and the occurrence of organic carbon at Byers Peninsula. This study aims therefore to investigate soil physical and chemical properties at Byers Peninsula, Maritime Antarctica, in particular, the distribution of organic carbon. Thirteen soil profiles were described, collected, and subjected to a physical, chemical, and spatial analysis. Colonization by avifauna and vegetation is important for inputing soil organic carbon at Byers Peninsula. Cryoturbation and permafrost are crucial for the redistribution of the C pool. Distribution of organic carbon on the Byers Peninsula have shown that its concentrations are higher and more punctual at the surface, but also that carbon has been redistributed to deeper layers. Gelisols (Cryosols) are important C pools. They are extremely useful from the environmental monitoring perspective as they represent areas sensitive to temperature increases on the Antarctic Peninsula caused by global climate changes. Using geomorphological groups is one way to improve the understanding of these relief forms, soil and rock types, vegetation patterns, and the presence of permafrost.

Navigating parenthood in a climate change era: determinants of childbearing intentions in Iran.

Scientific reports, 15(1):25552.

Climate change has significantly altered global ecosystems, including population dynamics, and consequently, decisions regarding childbearing. Climate change is considered one of the factors influencing childbearing intention. Therefore, the present study was conducted to explore the determinants of childbearing intention in women and men of reproductive age in the climate change era in Iran. The present qualitative study employs a conventional content analysis approach. The participants comprised 40 men and women of reproductive age residing in Qom, who were selected from February to July 2024 through purposive sampling while adhering to the principle of maximum diversity and were included in the study after providing informed consent. Data were collected through semi-structured individual interviews until theoretical saturation was achieved and were analyzed concurrently. During the inductive data analysis process, 360 codes and 5 main categories with 16 subcategories emerged. The main categories encompassed "Climate Change Awareness and Its Perceived Relevance to Childbearing Intention," "Ethical Dilemmas and Parental Responsibility," "Environmental and Economic Barriers to Childbearing," "Health Implications of Climate Change," and "Policy Demands for Climate-Resilient Parenthood." Childbearing intentions in the climate change era are shaped by a dynamic interplay of environmental, economic, health, and cultural factors. This understanding emphasizes the necessity of implementing multidisciplinary solutions to protect human health and fertility rates in the context of climate change.

Flexibility in the face of climate change? A rapid and dramatic shift towards later spring migration in Hudsonian godwits (Limosa haemastica).

Proceedings. Biological sciences, 292(2051):20250982.

With rapid environmental change, shifts in migration timing are vitally important for population stability in migratory species and have been widely documented. However, little remains known about how migrants make these shifts and what factors influence the utilization of these strategies, limiting assessments of their vulnerability to climate change. Hudsonian godwits (Limosa haemastica) are extreme long-distance migratory shorebirds that (i) have previously advanced their population-level migration timing and (ii) are sexually dimorphic. We combined over a decade of tracking data from one breeding population with a historical predictive model to assess ongoing shifts in migration timing and investigate potential sex-specific migration strategies. We found that irrespective of sex, godwit departure and arrival timing shifted 6 days later from 2010 to 2023. The population maintained an average migratory duration of 24 days and drove shifts in arrival timing entirely by changing their non-breeding-ground departure. Yet, we also found godwits arrived later than predicted by the historical model, indicating that conditions on the non-breeding grounds may constrain their ability to respond to changes on the breeding grounds. These results emphasize the need for a more holistic approach to assessing the vulnerability of migratory species and the adaptiveness of changes in migration timing.

Dispersal evolution can only rescue a limited set of species from climate change.

Proceedings. Biological sciences, 292(2051):20250116.

Anthropogenic climate change threatens biodiversity on Earth. In response, species can adapt evolutionarily to changing environments or shift their ranges via dispersal. However, dispersal itself can evolve on ecological timescales. We explore theoretically how dispersal evolution modulates the response of metacommunities to climate change. We find that this response depends on the environmental conditions prior to climate change. Variable environments harbour few, dispersive species that are likely to survive climate change by shifting their ranges with their evolved dispersal abilities. Stable environments house many, less dispersive species. Their survival during climate change is less likely, as they can evolve robust, low dispersal traits that prevent range shifts. We identify a limited set of scenarios in which contemporary dispersal evolution can rescue species from climate change, highlighting the importance of species' evolutionary histories and evolutionary rates, as determined by their genotype-phenotype maps, for their responses to rapid environmental change.

Ecological security patterns for coordinating development in frozen soil regions - construction framework by coupling climate change and development objectives.

Journal of environmental management, 391:126543 pii:S0301-4797(25)02519-8 [Epub ahead of print].

Ecosystems are facing serious degradation issues due to global warming and human activities. Construction of ecological security patterns (ESPs) has become an essential means to protect ecosystems. However, previous studies focus on a single indicator and lack coordinated assessment. This study integrates the MCCA, MOP, InVEST, and MCR models to propose a framework for constructing coordinated ESPs in frozen soil regions and applies it in Heilongjiang Province. Results indicate that: (1) By 2035, land use will stabilize with cropland and woodland maintaining a 93 % share, primarily changing in the Xing'an Range. (2) Ecosystem service values remain the "low-high-low" distribution with minimal changes in carbon storage, habitat quality, and crop production across all scenarios, while water yield and soil conservation change drastically only under the Economic Priority Development (EPD) scenario. (3) The EPD scenario reveals the broadest ecological sources (3.9 × 10[4] km[2]) and corridors (8746.7 km), though source fragmentation may pose risks in the future. The Business As Usual (BAU) scenario reveals the smallest ecological sources (2.2 × 10[4] km[2]) and longest ecological corridors (9449.3 km), which are inadequate to ensure ecological security. The Frozen Soil Protection (FSP) scenario indicates the most optimal ecological sources (3.2 × 10[4] km[2]) and corridors (8791.9 km), which can most effectively ensure ecological security. Combining the results, the "one ring, three corridors, and four cores" pattern is proposed. This paper has important reference value for optimizing ESPs in Heilongjiang Province and provides a framework of ESP for coordinating development in frozen soil regions.

Cross-border ungulate protection: Identifying transboundary conservation challenges and integrated solutions in response to human disturbance and climate change.

Journal of environmental management, 391:126483 pii:S0301-4797(25)02459-4 [Epub ahead of print].

Globally, over half of all terrestrial animals have ranges that cross international borders, making transboundary conservation crucial for protecting threatened species and their habitats. In Central Asia, the Hindu-Kush Karakoram-Pamir Landscape (HKPL), spanning Afghanistan, China, Pakistan, and Tajikistan is a critical habitat for mountain ungulates, including Marco Polo sheep (MPS) and Siberian ibex (ibex). These two wide-ranging and migratory species face significant challenges associated with habitat loss, competition with domesticated ungulates, and climate change. To better understand these challenges, we conducted a systematic review using the PSALSAR framework to identify the conservation challenges faced by each of these two ungulate species. We identified current and future suitable habitats using ensemble Species Distribution Models (eSDMs). Our models indicate that 44-48 % of suitable habitat for MPS and ibex currently falls within protected areas. However, under future climate scenarios, suitable habitat is projected to decline by up to 11 %. Most habitat loss will occur in the countries of China and Tajikistan. Despite protected areas and anti-poaching measures, both species face increasing habitat fragmentation, range restrictions due to border fencing, pasture overuse, disease transmission from livestock, illegal hunting, and inadequate law enforcement. Along with expanding habitat connectivity, separating livestock grazing zones, and restoring degraded habitat, transboundary cooperation is critical for species survivorship. We recommend expanding community-based conservation through education, incorporating traditional knowledge into management plans, and improving local food security through profit sharing. Actions taken to promote wildlife conservation in the HKPL can serve as a model for conserving mountain ecosystems globally.

Student perspectives on climate change and sustainability education in England: experiences and expectations.

UCL open. Environment, 7:e3341.

This paper presents findings from a large-scale survey of 2429 students in Years 7-9 (ages 11-14) in England, exploring their experiences and expectations of climate change and sustainability education. The study reveals that while most students learn about climate change and sustainability in school, primarily through geography and science lessons, there is a desire for a more comprehensive and engaging approach. Students express a strong interest in learning about the future impacts of climate change, practical solutions and global perspectives. They emphasise the importance of outdoor learning, hands-on activities and opportunities for meaningful participation in school and community initiatives. The findings highlight the need for climate change and sustainability education to be embedded across the school curriculum, to provide opportunities for outdoor learning, and to nurture student agency. Explored within a framework of children's rights to education and wellbeing and respective inequalities, this research provides valuable insights for stakeholders seeking to improve climate change and sustainability education and empower young people to address the climate and environmental crisis.

Differences in responses of invasive and native plants to climate change: a case study of Bidens (Asteracea) from China.

Frontiers in plant science, 16:1583552.

Global warming has emerged as one of the most pressing environmental challenges. Concurrently, plant invasion has been exacerbated by ongoing climate change, posing a severe ecological threat. This study investigates the distribution patterns of both invasive and native species within the Bidens genus and their responses to projected climate change. The MaxEnt model, was used to predict the potential distribution ranges under both current and future climate conditions. The results showed a distinct difference in suitable area distributions between invasive and native species. Under future climate scenarios, most studied species (except B. pilosa, B. maximowicziana, and B. radiata) showed an expansion in their suitable habitats. Notably, we observed a latitudinal migration pattern in Bidens species distribution, with invasive species primarily influenced by precipitation during the warmest quarter, while native species were more affected by anthropogenic factors. These results underscore the need for enhanced public awareness of invasion risks and the establishment of dedicated protection zones for both invasive and native species. This study provides critical insights into the potential distribution patterns of Bidens species under climate change. It also, offers valuable scientific support for development of invasive species management strategies and native species conservation mechanisms.

Climate-change-enhanced habitat diversification for the Middle Jurassic Yanliao Biota in East Asia.

National science review, 12(7):nwaf194.

The Jurassic Period was characterized by the dominance of dinosaurs and the rise of early mammals, with the Yanliao Biota (∼167-157 Ma) in East Asia notable for its exceptional fossil preservation and diverse life forms. However, the drivers of the flourishing of the Yanliao Biota remain unclear. Here, we reconstruct the palaeoclimate and habitat characteristics of the Yanliao Biota by using sedimentary facies analysis, organic carbon-isotope data, palynological records, source weathering trends and climate simulations from the Community Earth System Model CESM 1.2.2. The studied sedimentary successions are well constrained to the Middle Jurassic based on carbon-isotope stratigraphic correlation and published tuff zircon U-Pb ages. Our findings reveal a regional climate shift in the late Bathonian, transitioning from wet to sub-humid conditions, as evidenced by an increase in gymnosperm pollen, a marked decline in coal seams and reduced weathering intensity. Sedimentological evidence further supports a synchronous facies change from ever-wet fluvial-delta systems to seasonally active alluvial plains. This climate shift aligns with simulation results and coincides temporally with the initial flourishing of the Yanliao Biota. We propose that this shift, associated with lithospheric extension in the Yanliao region, increased landscape heterogeneity and habitat diversity, fostering biological evolution through ecological isolation and allopatric speciation, ultimately driving the diversification of the Yanliao Biota.

Effect of climate change on the health and nutritional status of children and their families in Africa: Scoping review.

PLOS global public health, 5(7):e0004897.

The health and nutritional status of children and their families is essential particularly during climate change. Most of the Sustainable Development Goals (SDGs) affect children in some way, namely, poverty (SDG 1), hunger (SDG 2), health (SDG 3), climate change (SDG 13). Evidence suggests that most countries are behind in achieving the SDGs, with only 17% of the SDGs currently achieved. The reason is because the SDGs are interconnected such that failure in one SDG, may affect the others negatively. For example, evidence from the global north provides many examples of the effects of climate change on other SDGs, particularly health. Within the global south, evidence of the effects of climate change on health is limited. This scoping review aims to document the effects of climate change on the health and nutritional status of children and their families in Africa. The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Three electronic databases were searched by a librarian. One reviewer screened the articles to be included in the synthesis and a second author went through the selected articles to confirm their inclusion. Data was extracted and mapped according to four categories: i) climate change events or phenomena, ii) effect of climate change on nutritional and health status, iii) factors influencing vulnerabilities of population to climate change, iv) interventions and innovations used to mitigate impact of climate change on health.

CO2-induced climate change assessment for the extreme 2022 Pakistan rainfall using seasonal forecasts.

NPJ climate and atmospheric science, 8(1):262.

While it is widely believed that the intense rainfall in summer 2022 over Pakistan was substantially exacerbated by anthropogenic climate change[1,2], climate models struggled to confirm this[3,4]. Using a high-resolution operational seasonal forecasting system that successfully predicted the extreme wet conditions, we perform counterfactual experiments simulating pre-industrial and future conditions. Both experiments also exhibit strong anomalous rainfall, indicating a limited role of CO2-induced forcing. We attribute 10% of the total rainfall to historical increases in CO2 and ocean temperature. However, further increases in the future suggest a weak mean precipitation reduction but with increased variability. By decomposing rainfall and large-scale circulation into CO2 and SST-related signals, we illustrate a tendency for these signals to compensate each other in future scenarios. This suggests that historical CO2 impacts may not reliably predict future responses. Accurately capturing local dynamics is therefore essential for regional climate adaptation planning and for informing loss and damage discussions.

Digitised herbarium specimen data reveal a climate change-related trend to an earlier, shorter Canadian Arctic flowering season, and phylogenetic signal in Arctic flowering times.

The New phytologist [Epub ahead of print].

The Arctic is experiencing some of the world's most rapid changes in climate. Arctic plant flowering time responses to climate change are understudied. Globally, conflicting evidence exists on whether flowering time responses to temperature are evolutionarily conserved. We scored the reproductive phenology of 17 000 digitised herbarium specimens of 97 plant species collected across the Canadian Arctic since the 1900s to determine whether and how flowering times in the Canadian Arctic have shifted over the past century; how responsive flowering times are to temperature; and whether flowering times and flowering time responses to temperature are evolutionarily conserved. We found that flowering times in the Canadian Arctic are converging, with later-flowering species shifting their flowering times to a greater degree than earlier-flowering species, resulting in a shorter flowering season. We detected a significant phylogenetic signal associated with Arctic flowering times but no phylogenetic signal in flowering time responses to temperature. A shorter flowering season in the Arctic has implications for tundra food webs and species interactions, with fitness consequences across tundra trophic levels. Digitised records allowed citizen scientists to become virtual collaborators in this project, and the research provided opportunities to improve digitised record quality for future research.

Integrated approach to explore Anemonia viridis regeneration under a climate change scenario.

Scientific reports, 15(1):25298.

This study investigates the mechanisms of regeneration in Anemonia viridis under natural conditions and thermal stress, addressing the question: "Does an anthozoan subjected to thermal stress regenerate similarly to one experiencing only a wound?". Oxidative stress markers (protein carbonylation, total antioxidant capacity) and symbiont photosynthetic efficiency (via Pulse Amplitude Modulation) were analyzed. Key proteins related to inflammation and tissue regeneration, including toll-like receptor, nuclear factor kappa B, heat shock proteins, and interleukin-1β, were examined using blotting techniques. Observations revealed higher antioxidant capacity at 20 °C than 27 °C after 6- and 24-hours post-injury. Thermal stress disrupted redox balance, as indicated by decreased symbiont photosynthetic efficiency. Protein expression analyses (proliferating cell nuclear antigen, heat shock protein 90, collagen Type XXIV α1) showed activation of compensatory mechanisms, but oxidative stress biomarkers highlighted significant cellular stress. These results suggest that elevated temperatures may impair regeneration in Anemonia viridis, highlighting a potential vulnerability of anthozoans to thermal stress associated with climate change.

Regional supply-chain impacts of Mississippi River fertilizer shipments disrupted by climate change.

Risk analysis : an official publication of the Society for Risk Analysis [Epub ahead of print].

The Mississippi River commercial navigation system faced unprecedented challenges in 2022-2023 due to severe heat and drought disrupting barge traffic. This caused a 400% surge in barge rates, disproportionately affecting the delivered price of key commodities. Our study analyzes the compound impact of low water levels and two potential additional sources of supply-chain disturbance-lock damage and import disruptions-both of which can also emanate from climate change. We combined an empirical analysis of the effect of low water levels on barge rates and productivity with a computable general equilibrium model to estimate their effects on the US economy and Upper Mississippi regional economy. These disruptions notably decreased GDP and increased inflation, especially affecting the five Upper Mississippi River states. This research underscores the river's vulnerability to compound disruptions and highlights its crucial role in regional and national economies.

Leveraging artificial intelligence for research and action on climate change: opportunities, challenges, and future directions.

Science bulletin pii:S2095-9273(25)00670-X [Epub ahead of print].

Research and action on climate change (RACC) represent a complex global challenge that requires a systematic and multi-dimensional approach. Although progress has been made, persistent limitations in data processing, modeling, and scenario evaluation continue to hinder further advances. Artificial Intelligence (AI) is emerging as a powerful tool to address these challenges by integrating diverse data sources, enhancing predictive modeling, and supporting evidence-based decision-making. Its capacity to manage large datasets and facilitate knowledge sharing has already made meaningful contributions to climate research and action. This paper introduces the RACC theoretical framework, developed through a systematic integration of the research paradigms of the three IPCC Working Groups (WGI, WGII, and WGIII). The RACC framework provides a comprehensive structure encompassing four key stages: data collection, scenario simulation, pathway planning, and action implementation. It also proposes a standardized approach for embedding AI across the climate governance cycle, including areas such as climate modeling, scenario development, policy design, and action execution. Additionally, the paper identifies major challenges in applying AI to climate issues, including ethical concerns, environmental costs, and uncertainties in complex systems. By analyzing AI-supported pathways for mitigation and adaptation, the study reveals significant gaps between current practices and long-term objectives-especially regarding content, intelligence levels, and governance structures. Finally, it proposes strategic priorities to help realize AI's full potential in advancing global climate action.

Assessing climate change impact on watershed hydrological processes and stream temperature by considering CO2 emissions.

Water research, 286:124161 pii:S0043-1354(25)01068-1 [Epub ahead of print].

Carbon dioxide (CO2) emissions are a critical indicator influencing climate change and have significant impacts on the health of riverine ecosystems. The effects of CO2 emissions on streamflow and stream temperature have not been explicitly considered in process-based models, which limits the models' capability to simulate streamflow and stream temperature under varying CO2 concentration scenarios. This study modified an equilibrium temperature model and a CO2 effect model to overcome this limitation, which were subsequently coupled with the Soil and Water Assessment Tool (SWAT) model. The coupled model was tested and applied in the Chaohe River basin in China from 2021 to 2080, and daily streamflow and stream temperature were simulated under the RCP8.5 and RCP4.5 scenarios based on the ACCESS and HadGEM climate models. The study showed that the coupled model performs well in simulating streamflow and stream temperature, with the PBIAS of less than ±10 %, and both the NSE and R[2] exceeding 0.85. Under both the ACCESS and HadGEM climate models, the simulations of streamflow and stream temperature exhibit a consistent pattern: increased CO2 concentration leads to higher air temperatures, which in turn elevates stream temperatures and changes streamflow mainly through evapotranspiration process. However, the lower CO2 concentrations or where snowmelt is significant in regions, streamflow and stream temperature exhibit greater variability. When CO2 levels are high to induce stomatal closure in plants, decreased evapotranspiration can lead to increased streamflow. In addition, headwater tributaries, primarily fed by rainfall, snowmelt, and groundwater, are located in high-altitude areas influenced by natural factors, while the main stem, mainly supplied by tributary inflows and precipitation, is situated in low-altitude areas affected by both natural and anthropogenic factors. This difference in water sources and influencing factors leads to distinct patterns in streamflow and stream temperature. Therefore, it is essential to develop algorithms that explicitly account for the impacts of CO2 concentration on hydrological processes and stream temperature dynamics, to accurately simulate the effects of climate change on streamflow and stream temperature, enabling the prediction of future climate change impacts on the thermal regime of river basins. The coupled model developed in this study provides a valuable tool for simulating the effects of CO2 on streamflow and stream temperature, offering insights into the complex interactions between climate change and hydrological processes.

Diatom-inferred water pH variability in response to climate change and acid deposition in subtropical peatlands.

Water research, 286:124153 pii:S0043-1354(25)01060-7 [Epub ahead of print].

Lake acidification emerged as one of the most pressing environmental issues in the 20th century, while peatland acidification is less investigated. Diatom assemblages in one hundred fourteen surface samples of eleven peatlands in South China and in peat cores of two peatlands covering a 200-year period were investigated. Ordination analyses revealed that water pH was the most important variable influencing diatom distribution in surface samples. Accordingly, a diatom-based pH transfer function was developed using a weighted averaging model with tolerance downweighting and inverse deshrinking, and applied to diatom records of two [210]Pb-dated sediment cores from Dajiuhu Peatland (Hubei Province) and Niangniangshan Peatland (Guizhou Province). Before the 1950s, declines in acid-tolerant diatom taxa coincided with rising diatom-inferred pH in both peatlands, indicating a regional shift toward less acidic conditions. This regional shift probably resulted from warming-accelerated bedrock weathering and alkalinity generation. Thereafter, the expansion of acid-tolerant diatoms mainly responded to enhanced atmospheric acid deposition, suggesting that its impacts outweigh those of climate warming. Temporal changes in diatom assemblages showed similar trends in the two distant peatlands, suggesting that acidification might be a widespread phenomenon in subtropical peatlands of South China after the 1950s. In spite of recent reductions in atmospheric deposition from 2010, diatom-inferred water pH continued to decline, indicative of delayed recovery from anthropogenic acidification in these headwater peatlands. The results provide novel insight into the timing and extent of peatland acidification in South China, and can inform sustainable management of semi-aquatic ecosystems under a changing environment.

Dual-quantification of the different contributions of climate change and anthropogenic activities to eutrophication of rivers and lakes in Asia's largest river basin (Yangtze River).

Journal of hazardous materials, 496:139205 pii:S0304-3894(25)02121-1 [Epub ahead of print].

The impact of anthropogenic activities and climate change on surface water eutrophication has been of great concern. However, the contribution proportions of anthropogenic activities and climate change to the lakes and rivers' eutrophication in large basins has not been clearly revealed. This study employed Geographically Weighted Regression (GWR) and Structural Equation Modeling (SEM) to conduct a dual quantification of the differential contributions of anthropogenic activities and climate change to the eutrophication of rivers and lakes in the Yangtze River Basin (YRB). Regression coefficients of GWR variables demonstrated the spatial heterogeneity of eutrophication drivers. Shapley additive explanations showed that nutrients and land use intensity were the main drivers during wet seasons. Combining the direct and indirect path results from SEM, the relative contribution of anthropogenic activities and climate change was 92.1 % and 7.9 % to river eutrophication, respectively, and was 67.1 % and 32.9 % to lake eutrophication, respectively. Anthropogenic activities consistently exacerbate eutrophication in both rivers and lakes, whereas climate change intensifies lake eutrophication but exerts seasonally variable effects on rivers. These findings revealed that intensive anthropogenic activities continue to dominate the eutrophication of the YRB. This study can provide a scientific reference for the integrated management of aquatic ecosystems in large basins.

A comprehensive review on the negative impacts on Sundarbans fisheries: Insights from the hydrological changes modulated by climate change and anthropogenic activities.

Marine pollution bulletin, 220:118409 pii:S0025-326X(25)00884-7 [Epub ahead of print].

The Sundarbans, the largest single block of transboundary mangrove that provides habitat, breeding and nursery grounds for fish and many other aquatic species, and livelihood for 3.5 million people, is currently under threat due to various reasons. In this review, we demonstrated the potential causes of alterations of the Sundarbans' hydrology and their likely impacts on its fisheries. Significant alterations in the Sundarbans' hydrology are induced by climatic variables (e.g., elevated temperature, cyclones, sea level rise, salinity fluctuation, erratic rainfall, floods, and droughts) and anthropogenic factors (e.g., pesticides, heavy metals, microplastics and oil spills, aquaculture, deforestation, harmful fishing practices, etc.). The interwoven impacts of climate change include destruction of habitats, crucial breeding and nursery grounds of fishes, degradation of water, shifting migration patterns, physiological disruption, loss of fish species, etc. Furthermore, human activities like deforestation, shrimp farming, oil spills, etc. produce both short- and long-term consequences on fisheries, such as poor water quality, chemical bioaccumulation, mortality, etc. Heavy metals and pesticides exceeded the acceptable limit in the edible tissues of fish and other aquatic organisms and may pose carcinogenic risk upon consumption. We identified major research gaps for future studies, including a lack of long-term assessment of climatic variables, insufficient data on pollutants, advanced climate modelling, etc. Lastly, we recommend reducing carbon footprint, forcing industries to use Effluent Treatment Plants (ETPs), declaring more conserved areas, initiating community-based management, etc. to address the issues brought on by climate change and anthropogenic activities that will ultimately help improve the overall fisheries resources in Sundarbans.

The connections of climate change with microbial ecology and their consequences for ecosystem, human, and plant health.

Journal of applied microbiology pii:8197886 [Epub ahead of print].

The climate crisis presents an urgent challenge for Earth's living creatures and the habitats in which they have been adapted to thrive. Climate-related stress presents risks to microorganisms, the stability of the functions they provide, and their maintenance of beneficial interactions with their hosts and ecosystems. Microbes move across the continuum of anthropogenic influence on Earth's ecosystems, from pristine to human-managed to fully urbanized environments. Because microbial feedback within and across this continuum exists at multiple, connected scales from molecules to ecosystem-level processes, predicting microbial responses to climate stress and their potentially wide-ranging consequences remains difficult. Here, we discuss the broad implications of microbial and microbiome responses to climate change as they interface with human, plant, and ecosystem health. For each section on human, plant and ecosystem health, we briefly discuss the state of knowledge for each and follow with proposed future research, including some directions that are promising but require more work to evaluate. We end by considering overarching microbial ecology research needs across these systems and microbial solutions under investigation as possible climate-resilient interventions to maintain human, plant, and ecosystem health. This work draws on diverse expertise to identify broad research directions across typically separated disciplines and builds a holistic framework for considering their interrelationships.

Leveraging Biochar Amendments to Enhance Food Security and Plant Resilience Under Climate Change.

Plants (Basel, Switzerland), 14(13):.

Climate change poses significant risks to food security and contributes to widespread soil degradation. Effective strategies are urgently needed to mitigate its impacts and ensure stable crop production and food quality. Biochar has shown strong potential to reduce greenhouse gas emissions, enhance carbon sequestration, and immobilize soil contaminants such as heavy metals and organic pollutants. These benefits can lead to increased crop yields, improved nutritional quality, and reduced uptake of harmful substances by plants. This review summarizes the possible mechanisms through which biochar influences the biochar-soil-plant interface, aiming to provide a comprehensive understanding of its multifaceted roles. Although positive effects of biochar on crop production are frequently reported, neutral or even negative outcomes have also been observed. Such adverse effects may be attributed to the presence of volatile organic compounds, free radicals, or heavy metals in certain biochars that inhibit plant growth. Additionally, biochar application has been found to reduce plant infections caused by pathogens, likely due to the presence of organic compounds that act as microbial inhibitors. A deeper understanding of the mechanisms by which biochar affects plant growth is essential for its effective use as a tool to combat climate change and enhance food security.

Analysis of a Potentially Suitable Habitat for Solanum aculeatissimum in Southwest China Under Climate Change Scenarios.

Plants (Basel, Switzerland), 14(13):.

Solanum aculeatissimum is a herbaceous to semi-woody perennial plant native to the Brazilian ecosystem. It has naturalized extensively in southwestern China, posing significant threats to local biodiversity. This study systematically screened and integrated 100 distribution records from authoritative databases, including the Chinese Virtual Plant Specimen Database, the Global Biodiversity Information Facility, and Chinese Natural Museums. Additionally, 23 environmental variables were incorporated, comprising 19 bioclimatic factors from the World Climate Dataset, 3 topographic indicators, and the Human Footprint Index. The objectives of this research are as follows: (1) to simulate the plant's current and future distribution (2050s/2070s) under CMIP6 scenarios (SSP1-2.6, SSP2-4.5, and SSP5-8.5); (2) to quantify changes in the distribution range; and (3) to determine the migration trajectory using MaxEnt 3.4.4 software. The findings reveal that human pressure (contributing 79.7%) and isothermality (bioclimatic factor 3: 10.1%) are the primary driving forces shaping its distribution. The core suitable habitats are predominantly concentrated in the provinces of Yunnan, Guizhou, and Sichuan. By 2070, the distribution center shifts northeastward to Qujing City. Under the SSP5-8.5 scenario, the invasion front extends into southern Tibet, while retreat occurs in the lowlands of Honghe Prefecture. This study underscores the synergistic effects of socioeconomic development pathways and bioclimatic thresholds on invasive species' biogeographical patterns, providing a robust predictive framework for adaptive management strategies.

Global Warming Impacts Suitable Habitats of the Subtropical Endemic Tree Acer pubinerve Rehder, Newly Recorded in Jiangsu Province, China.

Plants (Basel, Switzerland), 14(13):.

Global warming has caused the change of the geographical distribution of many species and threatened the living of species on earth. It is important to describe and predict the response of these species to current and future climate changes to conserve and utilize the endemic forest species. Acer pubinerve of the Sapindaceae is an important forest tree species endemic to China, our recent fieldwork recorded A. pubinerve in the Jiangsu province for the first time, representing the northernmost known occurrence of the species. In this study, we compiled an occurrence dataset of A. pubinerve based on field investigation, herbarium specimen data and literature, and mapped the resource distribution of this endemic forest species in China. Then, we used the optimized MaxEnt model to predict the potential suitable areas of the species under current climate conditions and future climate change scenarios and studied the impacts of environmental variables on the suitable areas of the species. The MaxEnt model, optimized with a regularization multiplier of 0.5 and a feature combination of linear and quadratic terms, exhibited the best predictive performance. The prediction accuracy of the model was extremely high and the AUC values of training and test data were 0.995 and 0.998, respectively. We found that the leading environmental variables affecting the potential distribution of A. pubinerve include the mean temperature of warmest quarter, the mean temperature of driest quarter, and the annual precipitation. Under the current climatic condition, the suitable distribution area of A. pubinerve is 165.68 × 10[4] km[2], mainly located in the provinces of Zhejiang, Fujian, Jiangxi, Hunan, Guangdong, and Guangxi. Compared with the suitable area under the current climate, the total suitable areas of A. pubinerve is projected to expand toward the north under the future climate change scenarios SSP126, SSP370, and SSP585, while its center shows a general trend of westward migration. Our study lays the foundation for conservation and resource utilization of this endemic tree species in China.

Thermal influence on development and morphological traits of Aedes aegypti in central India and its relevance to climate change.

Parasites & vectors, 18(1):279.

BACKGROUND: The geographic expansion of Aedes aegypti, an arboviral disease vector of global importance, is driven by urbanization, global travel, and climate change. Temperature significantly impacts the life cycle, distribution, and vectorial capacity of disease vectors. This study investigates the effects of temperature on the developmental biology, survival, reproductive traits, and wing morphometry of Ae. aegypti populations from central India (Bhopal, Madhya Pradesh).

METHODS: Larvae collected from the field were reared at controlled temperatures, on the basis of the historical and projected temperature changes, ranging from 10 ℃ to 40 ℃. Aedes stage-specific developmental times and survivorship rates were determined and compared. The right wings of male and female mosquitoes reared at 20 °C, 26 °C, and 32 °C were used for morphometric analysis on the basis of the digitized coordinates of 18 landmarks on the wing veins.

RESULTS: Higher temperature (32 °C) significantly accelerated life cycle completion, whereas 37 ℃ led to larval survival but high pupal mortality. In contrast, moderate temperatures (26 °C) optimized survival, reproductive output, and extended oviposition periods. Life table analysis revealed that elevated temperatures, particularly at 32 ℃, increased the intrinsic rate of population growth (rm) and shortened generation times, indicating faster population turnover under warmer conditions. However, this rapid life cycle presents trade-offs, including lower survival and reproductive success, which could significantly impact vector population dynamics in the context of climate-driven temperature fluctuations. Wing morphometric analysis further revealed that mosquitoes reared at 32 °C and 26 °C had significantly smaller wings compared with those reared at 20 °C. Although smaller wings may limit dispersal capacity, previous studies suggest a possible link with increased host-seeking and enhanced vectorial potential at 32 °C.

CONCLUSIONS: This study highlights that Ae. aegypti populations from Central India exhibit thermal tolerance and developmental plasticity under elevated temperatures, suggesting their potential to thrive in warm climates. Rapid development and smaller wing size at higher temperatures may influence survival, fecundity, and biting behavior. Such traits can enhance disease transmission risks by supporting more frequent human-vector contact and sustaining mosquito populations in broader geographic areas.

Planetary boundaries under a land-based climate change mitigation scenario with a food demand transformation: a modelling study.

The Lancet. Planetary health pii:S2542-5196(25)00087-7 [Epub ahead of print].

BACKGROUND: Ambitious climate change mitigation in all economic sectors is crucial for limiting global warming. Cost-effective mitigation pathways to keep global average temperature increases below 1·5°C by the end of the 21st century often rely on land-based greenhouse gas (GHG) emission reductions, increased land-based carbon uptake and biomass supply to other sectors (eg, energy and transport), and demand-side changes in the food system. To evaluate the broader sustainability of land-based climate change mitigation action, we evaluated synergies and trade-offs of individual and combined supply-side mitigation measures across five planetary boundaries. We also examined the role of a food demand transformation aligned with the dietary recommendations of the updated planetary health diet defined in the forthcoming EAT-Lancet Commission 2.0 report in shaping planetary boundary outcomes.

METHODS: In this modelling study, we used the dynamic land-system modelling framework MAgPIE to assess the consequences of land-based GHG reductions, increased land-based carbon uptake, increased biomass supply to other sectors, and a food-system transformation towards the planetary health diet including food waste reductions on five planetary boundary domains (climate change, nitrogen, land-system change, freshwater use, and biosphere integrity) relative to a reference scenario without land-system mitigation throughout the century. For each planetary boundary control variable, we calculated the level of planetary boundary transgression (ie, the extent to which scenario outcomes exceeded the defined safe operating space) and assessed the contributions of land-based mitigation strategies to reducing planetary boundary transgressions projected for the reference scenario.

FINDINGS: Our projections show that a food-system transformation together with ambitious land-system and energy-system climate change mitigation can limit global warming to below 1·5°C by 2100, while also reducing planetary boundary transgression (particularly for the climate change, land-system change, biosphere integrity, and nitrogen planetary boundaries). However, a safe operating space was not achieved through these mitigation measures, as most planetary boundaries were still projected to remain transgressed by the end of the 21st century. Increased bioenergy supply alone worsened planetary boundary transgression when only looking at land-system impacts, but combining increased bioenergy supply with GHG pricing in the land system alleviated these trade-offs. Food waste reductions and dietary shifts towards the planetary health diet were projected to ease pressures on the land system and reduce planetary boundary transgression of all assessed planetary boundaries.

INTERPRETATION: This research highlights the importance of considering multiple planetary boundaries and the interactions between various mitigation strategies when assessing climate mitigation action in the land system to avoid negative consequences for other aspects of the environment. Following an ambitious climate change mitigation pathway compatible with the Paris Agreement results in a transgression of all assessed five planetary boundaries by 2100. However, the combination of the land-system mitigation measures included in this study produced a substantial shift towards the safe operating space for humanity.

Addressing climate change concerns in pediatric health care settings: exploring parental and physician perspectives.

Environment international, 202:109661 pii:S0160-4120(25)00412-X [Epub ahead of print].

INTRODUCTION: In 2015, the American Academy of Pediatrics released a policy statement on pediatricians' role in battling the damaging effects of the climate crisis on children, a particularly vulnerable population. However, pediatric healthcare providers report difficulties integrating these discussions into their clinical practices. We designed a survey to evaluate the perceptions of parents and pediatricians regarding the health impacts of climate change, with the goal of identifying key opportunities for education and engagement.

METHODS: In this cross-sectional study, anonymous surveys were distributed to parents at 5 pediatric outpatient clinics in Southern New Jersey. A second anonymous survey was digitally distributed to physicians at the same outpatient clinics. We measured responses using a 4-point Likert scale and conducted a descriptive analysis, including frequencies, percentages, and 95 % confidence intervals.

RESULTS: We collected 111 parent surveys and 37 physician surveys. Many parents and physicians reported feeling worried (somewhat or very much) about the impact of climate change on their child's and patient's physical (57.4 % for parents, 83.8 % for physicians) and mental (30.0 % for parents, 64.8 % for physicians) health. The top three areas of climate health concern among parents were air pollution, vector-carried diseases, and allergens and pollen. The top three concerns for physicians were air pollution, allergens and pollen, and food security. Pediatricians reported that a lack of time (89.2 %) and knowledge (70.3 %) reduced their willingness (somewhat or very much) to discuss climate change during visits. When asked about solutions, they responded that patient education materials (75.6 %), communication training (70.2 %), and continuing professional education (78.3 %) would facilitate climate counseling (somewhat or very much).

CONCLUSIONS: Our results suggest that parents and pediatricians alike are concerned about the impact of climate change on child health. Additionally, pediatricians feel ill-equipped to integrate climate change education into their daily practices. Future efforts to provide additional resources to pediatricians can help both parents and patients face a worsening ecological climate.

Climate Change and the Microbial Shift: Unveiling Hidden Risks for Cancer Progression.

Cancer epidemiology, biomarkers & prevention : a publication of the American Association for Cancer Research, cosponsored by the American Society of Preventive Oncology pii:763548 [Epub ahead of print].

Climate change can lead to constant dysbiosis of the human microbiota, disrupting the delicate balance essential for maintaining good health. Climate change and its associated health risks are a growing area of research, yet its impact on human health, particularly for cancer patients and their relationship with microbes, remains largely unclear. While much attention is given to the effects of climate change on flora and fauna, its influence on microbes-both within the human body and in the environment deserves greater focus. Climate shifts can lead to constant dysbiosis of the human microbiota, disrupting the delicate balance, essential for maintaining good health. This interplay between host and environmental microbes is crucial for a healthy life. As climate change accelerates, it creates a favourable niche for pathogens, often exacerbated by antimicrobial resistance. Cancer patients, already immunocompromised, may be especially vulnerable to these microbial fluctuations driven by changing climates. Our review explores the existing studies that link climate change with microbial disturbances and how these shifts may contribute to cancer progression and accompanied comorbidities. Future research is essential to unravel the connection between climate change, microbial dysbiosis, and cancer development, shedding light on an often-overlooked threat to human health.

The impact of implementing the women's reproductive rights agenda on climate change.

Frontiers in global women's health, 6:1594066.

The 1994 International Conference on Population and Development (ICPD) established sexual and reproductive health and rights (SRHR) as foundational to sustainable development. Thirty years later, advancing women's reproductive rights (WRR), encompassing agency, decision-making autonomy, and universal access to family planning-remains critical not only for health and gender equity but also for mitigating environmental degradation. By reducing unintended pregnancies and empowering women to align childbearing with personal and ecological capacity, WRR alleviates ecological stressors such as deforestation while enhancing health resilience in climate-vulnerable communities. Yet, despite well-documented linkages between population dynamics and environmental change, contemporary climate policies and funding mechanisms persistently exclude WRR. This oversight undermines the potential of reproductive justice to enhance climate resilience. Additionally, claims that integrating WRR into climate agendas covertly promotes population control or represses women in low- and middle-income countries are fundamentally misleading. Crucially, research is needed to quantify the specific environmental impacts of WRR, underscoring the urgent need for robust global models to predict and validate these co-benefits. Strengthening this evidence base is imperative to inform policies that integrate WRR indicators into climate financing frameworks, ensuring gender-responsive programming. Bridging this gap requires interdisciplinary collaboration to develop metrics that capture WRR's role in reducing resource consumption and enhancing adaptive capacity. Embedding WRR within climate agendas would harmonize reproductive justice with environmental action, unlocking synergies between gender equity, health resilience, and sustainability. Fulfilling the ICPD's vision demands centering WRR in global climate strategies, thereby advancing a just and livable future for all.

Future habitat dynamics of critically endangered endemic plants in the St. Catherine protected area, South Sinai, Egypt: climate change perspectives on mountain ecosystems.

BMC ecology and evolution, 25(1):68.

BACKGROUND: Mountain ecosystems provide crucial insights into species distribution, yet their fragility, especially in the warming Mediterranean, puts many species at high extinction risk. This study, focusing on four critically endangered plants in Egypt's St. Catherine Protected Area (Primula boveana, Rosa arabica, Micromeria serbaliana, and Silene oreosinaica), uses Species Distribution Models (MaxEnt) and the IUCN Red List to assess climate change impacts and enhance future conservation strategies.

RESULTS: Field observations from 2024 to 2025 revealed changes in Extent of Occurrence (EOO) and Area of Occupancy (AOO) when compared to historical records. EOO increased for all species: P. boveana (72.8 km², + 280%), R. arabica (102 km², + 117%), M. serbaliana (88.5 km², + 30%), and S. oreosinaica (61 km², + 15%) as discovery of new and rehabilitated sites. This reclassified R. arabica from Critically Endangered (CR) to Endangered (EN), although the other species remain CR. Despite these geographical increases, both human and natural threats continue to cause declines in individual numbers and habitat quality. High predictive model accuracy was recorded (AUC ≥ 0.97, TSS ≥ 0.85). Under current conditions, P. boveana and R. arabica exhibit wider potential distributions (11.3% and 12.1% of the total area, respectively) than M. serbaliana (5.2%) and S. oreosinaica (5.4%). Areas with high probability of occurrence are primarily found in the northwestern mountains, often fragmented by topography. MaxEnt projected a decline in suitable habitats for these species, with new suitable areas emerging in SCPA's southern mountains. Future habitat reduction rates for the years 2050 and 2070 varied: S. oreosinaica (2-23%), P. boveana (7-32%), and M. serbaliana (2-41%), while R. arabica demonstrated high stability (> 96%).

CONCLUSIONS: Our findings show an altitudinal shift, with species moving to higher, southern mountains, experiencing habitat fragmentation and losses elsewhere. Effective conservation needs ongoing monitoring, in-situ/ex-situ efforts, and addressing threats like overgrazing. Raising environmental awareness is crucial.

Projecting stock market impacts of climate change via rational bubble models.

Risk analysis : an official publication of the Society for Risk Analysis [Epub ahead of print].

In this paper, we develop a rational bubble model to quantify the susceptibility of global stock markets to future temperature rises. The approach builds on existing theory incorporating the unpredictable timing of future Black-Swan events alongside price risks that increase in line with global temperature. An alternative specification where climate-change risks are instead linked to atmospheric carbon dioxide levels is also given. The approach offers simplicity, transparency and allows national-level effects to be estimated. In the short term, prices are artificially inflated and volatility artificially deflated as temperatures rise. This is in-line with previous work suggesting carbon-related risks are underpriced by markets. We use our model to estimate stock market exposure to future climate-change risks given future global temperature rises and increases in atmospheric C O 2 $CO_2$ . The potential effects are considerable once global temperatures increases beyond 2 ∘ C $2^\circ {\rm C}$ above preindustrial levels. We find that climate-change risks are priced in by certain G7 stock markets but not in smaller markets. Estimates of stock market losses directly attributable to global temperature rises up to 2 ∘ C $2^\circ {\rm C}$ above preindustrial levels are also given.

A machine learning approach to assess the climate change impacts on single and dual-axis tracking photovoltaic systems.

Scientific reports, 15(1):24910 pii:10.1038/s41598-025-10831-3.

Solar tracking system efficiency is affected by climate variability, and adaptive mechanisms must be employed to maximize energy output. Conventional fixed-tilt, single-axis, and dual-axis tracking techniques are not real-time adaptive, resulting in energy loss. This paper introduces COMLAT (Climate-Optimized Machine Learning Adaptive Tracking), an AI solar tracking system that employs climate prediction using CNN-LSTM for climate prediction, XGBoost for estimation of energy yield, and Deep Q-Learning (DQL) for real-time tracking control for solar efficiency optimization. One-year experimental research from January 2024 to January 2025 was conducted at Sitapura, Jaipur, India, with comparative studies of COMLAT and traditional tracking systems for seasonal variations and cloud cover conditions. Results confirm the 55% increase in energy production compared to fixed-tilt installations and 15-20% compared to dual-axis tracking due to its AI-based flexibility. The constructed model achieved 10-day solar irradiance forecasting with an RMSE of 23.5 W/m[2], outperforming the conventional LSTM and GRU baselines. XGBoost made predictions of energy output with an R[2] score of 0.94. COMLAT's reinforcement learning controller optimized tracking angles with sub-second latency while minimizing mechanical movement. The integration of hybrid artificial intelligence models allows COMLAT to continuously update its tracking angles in real time and is a scalable and industrially viable solution for smart grids, solar farms, and hybrid renewable energy systems. Increasing computational efficiency, integrating energy storage mechanisms, and optimizing self-learning algorithms will be areas of focus for future research to make it more applicable.

Climate change risks on key open marine and coastal mediterranean ecosystems.

Scientific reports, 15(1):24907.

Mediterranean open marine and coastal ecosystems face multiple risks that impact their unique biodiversity, with climate change representing a major ongoing threat. While these ecosystems are also under pressure from non-climatic anthropogenic drivers (e.g., overfishing, pollution), this study primarily focuses on risks related to climate change. To assess these risks and evaluate their confidence levels, we adopt the scenario-based approach of the Intergovernmental Panel on Climate Change (IPCC), relying on a review of literature projecting changes in Mediterranean Sea ecosystems. The main drivers of environmental change are sea level rise, ocean warming and acidification. Similar to global conditions, all Mediterranean ecosystems face high risks under all climate scenarios, with coastal ecosystems being more strongly impacted than open marine ecosystems. For these coastal ecosystems, risk levels are expected to become very high already once global warming exceeds 0.8 °C with respect to the 1976-2005 period. A few Mediterranean ecosystems (e.g., coralligenous and rocky coasts) are relatively more resilient compared to others, probably because of their long evolutionary history and the presence of a variety of climatic and hydrological conditions. However, high-emission scenarios in specific sub-basins, in addition to acidification impacts, could reduce this resilience, decreasing both habitat extent and ecosystem function dramatically. Overall, due to the higher observed and projected rates of climate change in the Mediterranean, compared to global trends, for variables such as seawater temperature and pH, marine ecosystems (particularly coastal) are projected to be under higher risks compared to the global ocean.

Climate change has increased the odds of extreme regional forest fire years globally.

Nature communications, 16(1):6390.

Regions across the globe have experienced devastating fire years in the past decade with far-reaching impacts. Here, we examine the role of antecedent and concurrent climate variability in enabling extreme regional fire years across global forests. These extreme years commonly coincided with extreme (1-in-15-year) fire weather indices (FWI) and featured a four and five-fold increase in the number of large fires and fire carbon emissions, respectively, compared with non-extreme years. Years with such extreme FWI metrics are 88-152% more likely across global forested lands under a contemporary (2011-2040) climate compared to a quasi-preindustrial (1851-1900) climate, with the most pronounced increased risk in temperate and Amazonian forests. Our results show that human-caused climate change is raising the odds of extreme climate-driven fire years across forested regions of the globe, necessitating proactive measures to mitigate risks and adapt to extreme fire years.

Climate change and geographic barriers exacerbate the spread and threat of Psacothea hilaris (Pascoe, 1857) in China: Insights from ensemble model, geographic barrier simulations, and niche analysis.

The Science of the total environment, 994:180032 pii:S0048-9697(25)01672-9 [Epub ahead of print].

Climate change is a key driver affecting global ecosystems and biodiversity, particularly influencing the spread and distribution of forest pests in forest ecosystems. Psacothea hilaris (Pascoe, 1857), an important forestry pest, poses a serious threat to the mulberry industry and the health of forest ecosystems. This study integrated an ensemble model, geographic barrier analysis, and niche modelling to evaluate habitat suitability and future range shifts of P. hilaris under different climatic scenarios, and formulated corresponding prevention and control strategies. The results indicated that the ensemble model exhibited high accuracy (AUC = 0.97; TSS = 0.81). Mean diurnal range, precipitation seasonality, and precipitation of warmest quarter were the key drivers affecting the distribution of P. hilaris, and the response curves further revealed the existence of a non-linear pattern of these factors on its survival probability. Currently, P. hilaris is mainly distributed in central and southern China, while in the future, the area of its suitable habitat is expected to increase by 13.61 % to 64.04 %, and the centre of its distribution will move to higher latitudes. Multivariate environmental similarity surface (MESS) confirmed that the bioclimatic conditions in the future expansion area are highly similar to the current conditions. Moreover, the ecological niche overlap of P. hilaris will exceed 0.81 in the future periods. Additionally, topographic barriers did not significantly limit the dispersal ability of P. hilaris. This study not only provides data support for the development of refined control measures and ecological risk assessment for P. hilaris, but also provides valuable reference for the optimization of forest pest control strategies and ecosystem protection in China.

Factors influencing farming households' climate change adaptation strategies in Central Vietnam.

PloS one, 20(7):e0328058.

This study investigates the determinants of household-level adaptation strategies to climate variability and saltwater intrusion in the coastal regions of Central Vietnam. Using a Multinomial Logistic Regression (MNL) model, the analysis is based on a cross-sectional survey of 356 farming households, focusing on four primary adaptation measures: vegetable production, shrimp farming, adoption of salt-tolerant rice varieties, and the lotus-fish farming model. The results reveal that socio-economic, demographic, environmental, and institutional factors significantly influence the adoption of specific adaptation strategies. Key determinants include gender, education, age, farming experience, household income, land characteristics, access to information, credit services, membership in civic organizations, and participation in training programs. Male-headed households and those with greater access to climate information and social networks were more likely to adopt diverse and complex adaptation strategies. In contrast, households with limited land resources, lower incomes, or lacking institutional support were less adaptive. The findings highlight the heterogeneity of adaptive behaviors and the need for tailored interventions. From a policy perspective, enhancing institutional capacity-especially through targeted training, increased access to subsidized credit, and support for community-based organizations-can significantly strengthen farmers' adaptive capacities. Moreover, the study contributes to filling key research gaps in the Southeast Asian context by integrating socio-economic and environmental variables into a unified analytical framework. These insights are critical for designing inclusive and effective climate adaptation policies aimed at safeguarding rural livelihoods and promoting sustainable agricultural development in climate-vulnerable regions.

Defending rice crop from blast disease in the context of climate change for food security in Nepal.

Frontiers in plant science, 16:1511945.

Blast, caused by Pyricularia oryzae (teleomorph Magnaporthe oryzae), is one of the most devastating diseases in rice, causing 10-30% yield losses and threatening Nepal's food and nutritional security. The Himalayan foothills are hotspots for blast fungus diversity, leading to the rapid emergence of pathotypes that overcome resistance in mega rice varieties. In 2022, a neck blast epidemic devastated 5,000 hectares of Hardinath-1, a dry winter/spring rice variety in Chitwan, causing nearly 100% yield loss. The changing climate, especially during panicle initiation stages, has become more favourable for neck blast development. We reviewed 40 years of research and development on rice blast in Nepal, analysing historical weather patterns and mapping the incidence and severity of the disease across the country based on empirical observations and field experiments. Using historical data on rice blast incidence and climate information, we show that rice blast pressure is increasing intensively and changing weather patterns are becoming more favourable for rice blast epidemics. We identify emerging issues in rice blast and propose integrated strategies for effective management in Nepal. Key approaches include developing durable blast-resistant and climate-resilient rice varieties using molecular markers and genomic tools and speed breeding, forecasting disease and pathotype emergence, and combining these with careful use of modern fungicides, plant defence activators, and biological control. Additionally, adjusting planting times, managing weeds, optimising agronomic practices, and ensuring proper water and nutrient management are essential for sustainable blast management.
