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.

Future Atlantification of the European Arctic limited under sustained global warming.

Scientific reports, 15(1):30802.

Atlantification is an ongoing oceanic phenomenon characterised by the expansion of the typical Atlantic domain towards the Arctic, driving rapid oceanic and ecological changes in the European Arctic. Using reanalyses and a multi-model ensemble of unperturbed and transient preindustrial, historical and future-scenario simulations, this study shows that modern Atlantification possibly initiated in the late nineteenth century, preceded by several "Arctification" episodes in the preindustrial millennium. In the historical period, Atlantification and pan-Arctic warming superposed constructively to drive upper-ocean warming and salinification in the Barents Sea. Modern Atlantification is projected to continue in the next few decades, fully revealing its exceptional character in the context of the past millennium. However, Atlantification halts during the second half of the twenty-first century, decoupling from pan-Arctic warming. The northward expansion of the Atlantic domain is hindered by the onset of a damping mechanism where the Atlantic-Arctic density gradient increases progressively, which sustains a countercurrent by baroclinic adjustment pushing the Arctic polar front southward. As the evolution of this density gradient is intertwined with the retreat of the sea-ice edge, a late-summer ice-free Barents Sea may mark the end of modern Atlantification.

Global warming reduces the carrying capacity of the tallest angiosperm species (Eucalyptus regnans).

Nature communications, 16(1):7440.

Rising temperatures and increased frequency and intensity of droughts and heat waves have affected tree mortality rates worldwide. Here, we investigate how these changes have affected the carrying capacity of mountain ash forests (Eucalyptus regnans), the world's tallest flowering plant and one of the most carbon-dense forests on earth. We analyze data from a large network of silvicultural experiments collected between 1947 and 2000 in southeastern Australia to identify trends in mortality rates and carrying capacity for the species, and to quantify how these changes relate to spatiotemporal variations in climate. We show that forests growing in the warmest and highest vapor pressure deficit conditions had the lowest carrying capacity, and this capacity further decreased with rising temperatures. Key findings indicate that a projected three °C increase in temperature by 2080 could reduce tree density and carbon stock in these forests by 24%, equivalent to losing 240,000 hectares of mature mountain ash forests. Trees that died were 0.62 times the size of living trees (i.e., they were suppressed), with no detectable effect of climate on this ratio. We discuss the implications for forest conservation and management, and how reduced carrying capacity could undermine global forest restoration and carbon sequestration efforts.

Need for Nursing Advocacy to Address the Effects of Climate Change on Maternal and Neonatal Care.

Journal of obstetric, gynecologic, and neonatal nursing : JOGNN pii:S0884-2175(25)00232-1 [Epub ahead of print].

Extreme heat and air pollution, which are exacerbated by climate change, worsen maternal and neonatal health, especially for non-White women. Because of the wide array of health risks related to climate change, advocating for individual patients alone is not sufficient to create necessary change. Although nurses experience numerous barriers to engaging in public policy, their engagement remains a critical aspect to improving maternal and neonatal health outcomes related to climate change. Professional nursing organizations can provide nurses with resources and offer the necessary skills to effectively advocate and participate in public policy at the local, state, or national level. In this commentary, I review the importance of nurse engagement in climate change advocacy and public policy.

The synergy of environmental awareness, occupational physical activity and effects of climate change in German craftspeople.

International journal of occupational safety and ergonomics : JOSE [Epub ahead of print].

Objectives. Craftspeople are exposed to climatic changes while engaging in high levels of occupational physical activity. The purpose of this study is to investigate the synergies of occupational physical activity, effects of climate change and tangibility concerning the working conditions and health of German craftspeople. Methods. A questionnaire survey was conducted with 1830 responding German craftspeople using computer-assisted telephone interviews (CATIs). Quantitative analyses included physical activity, environmental awareness and the impact of climate change on daily work. An open question was assessed using qualitative content analysis. Results. The effects of climate and environmental change on daily work are most noticeable for men (30.6%), older workers (age 50-59 years, 31.7%), construction site workers (41.9%) and those who engage in physically demanding work (35.2%). The participants reported extreme weather conditions in combination with occupational physical activities as the most tangible effects of climate change with physical health effects. Conclusions. Craftspeople do feel the effects of climate change in their daily work and at the same time have a high level of environmental awareness. Given the prevalence of high levels of work-related physical activity, more attention should be paid to health risks and preventive measures should be taken.

Priority areas for nature-based adaptation to climate change in the Alps.

Ambio [Epub ahead of print].

Nature-based Solutions (NbS) are promising initiatives for climate change adaptation, mitigation and biodiversity conservation. Given the finite human and financial resources for NbS, identifying optimal locations is critical. Here, we identified priority areas for drought adaptation in the European Alps using the "bright spots" approach to estimate future water deficit and surplus from groundwater and soil moisture. We identified overlaps and mismatches of these priority areas with mitigation and biodiversity conservation opportunities. Our analyses reveal that priority areas for adaptation have limited overlap with regions prioritised for mitigation or biodiversity conservation. We considered potential levers to implement NbS from local socio-ecological characteristics. Notably, over 60% of croplands and wetlands identified as priority areas overlap with protected areas. In contrast, over 52% of priority areas for adaptation in forests and grasslands are located in rural regions without protection status, where participatory processes with local communities will be crucial to implement NbS.

[Climate change and its impact on emergency and disaster medicine].

Revue medicale suisse, 21(927):1447-1449.

Climate change represents a major challenge for emergency and disaster medicine, with both direct and indirect impacts on healthcare systems. It leads to an increase in heat-related illnesses, the multiplication of natural disasters, and the spread of infectious diseases, while also worsening mental health disorders. To adapt to these challenges, several strategies are necessary: strengthening the resilience of hospital infrastructures, integrating climate risks into medical training, optimizing epidemiological surveillance, and reducing the carbon footprint of the healthcare sector. A coordinated approach between healthcare stakeholders and governments is essential to mitigate the consequences of climate change on public health.

Responses to climate change - insights and limitations from herbaceous plant model species.

The New phytologist [Epub ahead of print].

Herbaceous plant species have been the focus of extensive, long-term research into climate change responses, but there has been little effort to synthesize results and predicted outlooks. This primer summarizes research on climate change responses for eight intensively studied herbaceous plant species. We establish generalities across species, examine limitations, and propose a path forward. Climate change has reduced fitness, caused maladaptation, and/or led to population declines in at least part of the range of all six forb species. Plasticity alone is likely not sufficient to allow adjustment to shifting climates. Most model species also have spatially restricted dispersal that may limit genetic and evolutionary rescue. These results are surprising, given that these species are generally widespread, span large elevation ranges, and have substantial genetic and phenotypic variation. The focal species have diverse life histories, reproductive strategies, and habitats, and most are native to North America. Thus, species that are rare, habitat specialists, or endemic to other parts of the world are poorly represented in this review. We encourage researchers to design demographic and field experiments that evaluate plant traits and fitness in contemporary and potential future conditions across the full life cycle, and that consider biotic interactions in climate change responses.

Physiological responses of Arctic and Baltic Sea populations of toxigenic Alexandrium ostenfeldii (Dinophyceae) to different climate change stressors.

Harmful algae, 148:102918.

The harmful algal bloom species Alexandrium ostenfeldii has a worldwide distribution from polar to tropical habitats and from oceanic to brackish waters. Among other species of the genus Alexandrium, it is one of the causative organisms of paralytic shellfish toxins, but additionally, A. ostenfeldii has also been shown to produce another class of toxins, cyclic imines. The wide distribution of A. ostenfeldii suggests population-specific adaptations to a multitude of environmental parameters and therefore, variable responses to global change drivers, such as warming and shifts in sea surface salinity. In this study we quantified growth and toxin cell quota of two strains of A. ostenfeldii isolated from the arctic Kongsfjord and two strains from the northern European Baltic Sea at various temperature conditions, to assess the impact of global warming on locally adapted populations. Overall, growth of the arctic strains was detected at temperatures between 7.5 and 20 °C, with a maximum growth rate at 15 °C for both strains. The two strains from the Baltic Sea revealed intraspecific differences concerning their thermal tolerance. One strain showed no growth at 25 °C, while the other still had a positive growth rate at 27 °C. Furthermore, three of the strains were exposed to salinities between 10 and 40, revealing a tolerance to a broad range of salinities. Neither temperature nor salinity affected the qualitative toxin composition of any strain, but we detected novel cyclic imines in three of the four tested strains. Furthermore, different temperatures and salinities led to dynamic shifts in total toxin cell quota. Additionally, we detected novel spirolides in both arctic strains of A. ostenfeldii. These findings suggest that arctic A. ostenfeldii might significantly benefit from global warming, while populations from the Baltic Sea may not, and that the Baltic Sea might become unfavourable for western Baltic A. ostenfeldii due to climate change driven decreasing salinity in this area.

Enhancing midwifery course curricula: validating knowledge and skills in climate change and planetary health.

Midwifery, 149:104573 pii:S0266-6138(25)00291-8 [Epub ahead of print].

PROBLEM AND BACKGROUND: Undergraduate midwifery courses prepare students for the care of childbearing women and their infants but lack specific content and skill development related to addressing the effects of a warming climate and increasing severe weather events. .A framework of Planetary Health nursing domains including: 1) The science of planetary Health and climate change, 2) Mitigation of the adverse impacts of healthcare on the environment, and 3) Adaptation to the actual and expected impacts of climate change on health care and health outcomes were identified from a previous Delphi study. These needed validation for use in undergraduate midwifery programs AIM: To validate previously identified nursing domains, knowledge, and skill statements and determine their appropriateness for undergraduate midwifery curricula in Australia.

METHODS: A modified Nominal Group Technique was used to ensure all seven participants, who were midwifery academics from multiple sites with an interest in Planetary Health, had the opportunity to voice their opinions and ideas in order to achieve consensus on the previously created nursing domains.

FINDINGS: Minimal changes to the nursing knowledge and skills statements were deemed necessary to ensure their relevance to midwifery programs.

DISCUSSION: Midwives promote the health of childbearing women by addressing environmental and social determinants of health. The warming climate and increasing number of severe weather events pose increased hazards for perinatal health. All midwifery graduates need the knowledge and skills to advocate for, and address environmental and social determinants of health, contribute to planetary health, bolster resilience and diminish community vulnerability to climate change. The incorporation of these Planetary Health domains into midwifery curricula will help address the current gap.

CONCLUSION: This study provided content and face validity for previously developed knowledge and skills statements on planetary health, climate change and sustainability for use within undergraduate midwifery courses.

The impact of climate change on the distribution of serpulid polychaetes: an ecophysiological approach.

Journal of thermal biology, 132:104228 pii:S0306-4565(25)00185-8 [Epub ahead of print].

Temperature influences the physiological performance of marine ectotherms-affecting survival, growth, and reproduction-and ultimately shaping their distribution. However, knowledge of how ocean warming will impact sessile ectotherms, such as serpulid polychaetes, remains limited. We hypothesize that rising ocean temperatures will affect serpulid thermal performance, potentially altering their distribution patterns. By combining laboratory-derived ecophysiological data with satellite sea-surface temperature (SST) data, we evaluated the effects of ocean warming on the distribution of two serpulid species from distinct regions: the temperate northern Pacific (Spirobranchus spinosus) and the tropical eastern Pacific (Spirobranchus cf. corniculatus). Adult worms were collected from the wild and acclimated for 30 days at different temperature ranges (11-20 °C for S. spinosus; 24-33 °C for S. cf. corniculatus) to assess thermal tolerance limits (CTmax, CTmin), thermal tolerance window, optimal temperature, and thermal safety margins. These physiological data were integrated with SST data to model potential distributions for both present (2010-2020) and future (2090-2100, SSP5-8.5) climate change scenario. Thermal tolerance limits increased with acclimation temperatures in both species. However, S. cf. corniculatus exhibited similar CTmax (35.1 °C) values at 30 and 33 °C, suggesting it is approaching its upper thermal limits. Both species exhibited narrow thermal windows (S. spinosus: 37 °C[2]; S. cf. corniculatus: 71 °C[2]), characteristic of stenothermic species. The optimal temperatures were 14 °C for S. spinosus and 30 °C for S. cf. corniculatus. By century's end, thermal safety margins are predicted to decrease, leading to range retractions in S. spinosus and potential poleward expansions in S. cf. corniculatus. These findings underscore the importance of integrating physiological and environmental data to assess the vulnerability of sessile ectotherms to climate change. Although other factors such as pH, currents, and oxygen may influence future distributions, this study provides an important first step toward understanding climate change impacts on sessile marine ectotherms.

Understanding climate change threats to vertebrate wildlife by studying ecoimmunology across biological scales.

Integrative and comparative biology pii:8238650 [Epub ahead of print].

Climate change threatens organismal health and ecological stability in myriad ways, the impacts of which are often difficult to characterize given their complex and interacting nature. To facilitate comparisons across taxa and ecosystems, we discuss the importance of a cross-scale approach to better characterize the ways in which climate change processes threaten wildlife immunity. Centering available examples from the vertebrate wildlife literature, we supplement with examples from the livestock literature to illustrate ways in which abiotic stress impacts immunity from molecular to community scales of biological organization. To highlight opportunities for cross-scale integration, we present a series of vignettes-drought, temperature extremes, storms and flooding, and habitat alterations and shifts-prior to discussing the complexities inherent to studying multiple interacting threats using heavy metal contamination as an example. Finally, we outline mechanisms by which collaborations across disciplines and sectors can continue strengthening capacity for studying the drivers of climate change-associated threats to wildlife immunology.

Unraveling Nonlinear Interactions: A DPSIR-Based Conceptual Model for Synergistic Impacts of Climate Change and Human Activities on Coastal Blue Carbon Ecosystems.

Global change biology, 31(8):e70432.

Coastal blue carbon ecosystems (BCEs) face accelerating degradation from synergistic climate-human pressures, threatening their carbon sink function. This review synthesizes nonlinear interactions governing BCE carbon cycles by developing a novel DPSIR (Drivers-Pressures-State-Impacts-Responses) conceptual model. Our framework integrates biogeochemical processes (e.g., photosynthesis, carbonate dynamics) and physical transport mechanisms (e.g., lateral carbon fluxes) to elucidate multi-factor couplings-such as nutrient pollution, hydrological alteration, and species interactions-that drive spatiotemporal variability in carbon storage. Crucially, we identify how anthropogenic drivers amplify biogeochemical feedback loops that destabilize carbon sequestration, while restoration strategies can rebuild resilience. To enhance monitoring efficacy, greenhouse gas flux periodicity and CO2/CH4 emission ratios are proposed as diagnostic indicators for BCE health assessment. The analysis reveals persistent knowledge gaps in quantifying inorganic carbon cycling, microbial responses under warming, and cross-system carbon fluxes. We emphasize that effective conservation requires integrated policies balancing blue economy development with science-based management, such as payment for ecosystem services and bioremediation. This DPSIR model advances a holistic understanding of BCE carbon-climate feedbacks, providing a foundation for safeguarding these critical ecosystems under global change.

The Interplay Between Mindful Eating, Climate Change Awareness, and Psychological Well-Being: A Cross-Sectional Analysis.

Food science & nutrition, 13(8):e70716.

Climate change poses significant threats to both environmental and human health, with dietary patterns playing a crucial role in mitigating these threats. The Mediterranean diet (MD) is widely recognized for its sustainability and health benefits, while mindful eating practices are associated with improved psychological well-being. However, the interplay between mindful eating, climate change awareness, and psychological well-being remains underexplored. This study aimed to examine the relationships between mindful eating behaviors, adherence to the Mediterranean diet, climate change awareness, and psychological well-being in a cross-sectional sample. A total of adult participants (n = 1350, aged 18-65) completed an online survey assessing the Mediterranean Diet Adherence Scale (MEDAS), Four Facet Mindful Eating Scale (FFaMES), Psychological Well-Being Scale (PWBS), and Climate Change Awareness Scale (CCAS). Correlation and linear regression analyses were conducted to determine the associations and predictors of psychological well-being. A significant positive correlation was observed between mindful eating and psychological well-being (p < 0.05). Additionally, adherence to the Mediterranean diet was positively associated with climate change awareness (p < 0.05). However, an unexpected negative association was found between Mediterranean diet adherence and psychological well-being (β = -0.086, p = 0.001). Regression analyses identified mindful eating (β = 0.159, p < 0.001), climate change awareness (β = 0.069, p = 0.010), and Mediterranean diet adherence (β = -0.086, p = 0.001) as significant predictors of psychological well-being, with the model explaining 48% of its variance (R [2] = 0.48, p < 0.001). These findings highlight the complex interactions between dietary habits, mindfulness, and mental health. Further research is needed to explore the causal mechanisms underlying these relationships and to develop interventions that promote both sustainable eating behaviors and mental health resilience.

Climate Change Impacts on the Phenology of Laurentian Great Lakes Fishes.

Global change biology, 31(8):e70436.

Freshwater ecosystems around the world are increasingly impacted by climate change, yet there remains a lack of long-term empirical data on how these changes are manifesting. In the Laurentian Great Lakes, a globally significant freshwater system, fish and their habitats are expected to be affected by warming water temperatures and increasing risks of species invasions. Despite these projections, relatively few studies have documented whether such shifts are already occurring. Our objective was to assess how climate change has influenced the community and migration phenology of native and non-native fishes that use coastal wetlands in the Great Lakes. To do so, we analyzed local summer water temperatures and a 27-year dataset (1997-2023) comprising arrivals of 16 fish species intercepted at the Cootes Paradise Marsh Fishway, a common carp (Cyprinus carpio) exclusion barrier at the western end of Lake Ontario. Over the study period, we found that mean summer water temperatures increased by over 1°C, consistent with broader global warming trends. Using non-metric multidimensional scaling, we observed a unidirectional shift in fish community structure over time, rather than cyclical fluctuations or stabilization, indicating sustained ecological change. Analyses on phenology revealed that first, peak, and last arrival dates occurred earlier over time, while the duration of presence at the Fishway decreased for both native and non-native species. These results provide evidence that climate change is already altering the community and phenology of fishes in Great Lakes wetlands. More broadly, our findings contribute to the growing body of literature showing that climate-driven phenological shifts are reshaping freshwater ecosystems globally, underscoring the need for adaptive, climate-informed conservation and management strategies.

Nursing Students' Global Warming Knowledge and Sustainability Attitudes: The Moderating Role of Eco-Anxiety.

International journal of mental health nursing, 34(4):e70122.

Recently, global warming and climate change knowledge and sustainability attitudes have gained prominence in nursing education; however, studies are scarce about how eco-anxiety moderates between these associations. This study explored the moderating role of nursing students' eco-anxiety between global warming knowledge and sustainability attitudes. Utilising a cross-sectional and correlational design, nursing students (n = 561) were recruited via consecutive sampling between November 2024 and February 2025. Three standardised scales were used to collect data. Structural equation modelling was employed for data analyses. The two dimensions of global warming knowledge, knowledge of climate change and global warming (β = 0.14, p = 0.021) and awareness of the environment (β = 0.37, p = 0.003), had a direct, positive influence on sustainability attitudes. Global warming knowledge was positively associated with eco-anxiety (r = 0.18, p = 0.001). Eco-anxiety negatively influenced sustainability attitudes (β = -0.56, p = 0.020). Eco-anxiety significantly moderated the influence of the two dimensions of global warming knowledge, knowledge of climate change and global warming (β = -0.29, p = 0.005) and awareness of the environment (β = 0.93, p = 0.003), on sustainability attitudes. Our findings may guide nursing curriculum policymakers, nursing colleges and educators, and healthcare institutions to integrate global warming, climate change and eco-anxiety in their academic and clinical experiences to better prepare future nurses to care for populations and the environment affected by its negative impacts.

Analysis of psychological and social factors affecting climate change adaptation and mitigation behaviors among Iranian rice farmers.

Scientific reports, 15(1):30431.

Rice is a vital staple crop, feeding billions globally. However, conventional rice farming practices, especially traditional irrigation techniques, are significant contributors to greenhouse gas (GHG) emissions. Flooded irrigation, in particular, creates anaerobic conditions that facilitate methane production-a GHG significantly more potent in terms of global warming potential compared to carbon dioxide. As a result, rice cultivation is a key driver of climate change (CC). Addressing these environmental challenges while maintaining sustainable productivity requires the adoption of climate-smart agricultural practices. This study explores the factors influencing the adaptation and mitigation behaviors of Iranian rice farmers in response to CC. Utilizing the Theory of Planned Behavior (TPB) and Value-Belief-Norm (VBN) theory as theoretical frameworks, the research examines psychological and normative drivers that shape farmers' decision-making. This research was carried out in Shushtar County, located in Iran's Khuzestan Province in the southwest. The study utilized a structured survey tool, and the collected responses were analyzed through structural equation modeling (SEM). The results indicate that TPB more effectively explains adaptation intentions, while VBN provides greater insight into mitigation behaviors. The integrated TPB-VBN model accounts for 64.2% of the variance in adaptation intentions and 67.6% in mitigation intentions. These findings offer valuable insights for policymakers aiming to foster sustainable rice farming practices that align with CC adaptation and mitigation objectives.

Temporal trends in allometry of shell calcification in northeastern Pacific venerid bivalves: implications for predicting responses to climate change.

Biology letters, 21(8):20250181.

Despite literature spanning almost a century, how allometric relationships of phenotypic traits behave over evolutionary time remains poorly known for most marine species. In particular, the fossil record is seriously underutilized in this context despite harbouring a rich archive of traits. Here we use the late Pleistocene fossil record in San Diego, California, in conjunction with archival and field collected specimens, to quantify temporal changes in allometric relationships between shell size and calcification, two important functional traits, in five different species of marine bivalves. Our results reject the traditional hypothesis that allometric relationships are invariant over time. They also show that temporal changes in allometric relationships are species-specific, with closely related species showing divergent trends. Finally, we argue that information about the nature of long-term changes in allometric relationships of functionally important traits can provide a powerful yet underappreciated tool for understanding species and population responses to climate change.

How do production practices and climate change impact the water footprint of dairy farms?.

The Science of the total environment, 998:180243 pii:S0048-9697(25)01883-2 [Epub ahead of print].

Understanding water use in dairy production systems is crucial to promoting production practices and enhancing resilience to climate change. The study aimed to evaluate how production practices and climatic scenarios in different dairy farming systems influence the water footprint of milk production. A total of 67 dairy cattle farms were selected for the study. Climatic scenarios and production practices were proposed as farm-specific interventions targeting three key areas: animal feed, effluent treatment, and nitrogen field application. For all production systems, the combinations exhibiting the highest water efficiency were characterized by the following factors: for green water, a 25 % increase in corn and soybean yields; for blue water, a reduction in milking parlor washing water consumption, an increase of 1 liter of milk per cow per day, and/or a reduction of 1 kilogram in dry matter intake per cow per day; and for grey water, the treatment of effluent from the milking parlor. Conversely, the combinations with the lowest water efficiency were identified as follows: for green water, maize yields decreased by 15 % and soybean yields increased by 12.95 %; for blue water, an increase of 1.5 °C to 2.5 °C in minimum daily temperature and/or a reduction of 1 kilogram in dry matter intake per cow per day; and for grey water, the non-treatment of effluent with the maximum value of α. The findings of this study establish production practices in water scenario analyses concerning water footprints in dairy cattle production systems.

The synergistic effects of climate change and fertilizer on crop yield: evidence from winter wheat in China.

Journal of the science of food and agriculture [Epub ahead of print].

BACKGROUND: Climate variability and agricultural management practices, particularly fertilizer use, jointly determine crop production and food security. Understanding their synergistic effects is essential for developing climate-resilient farming strategies, yet the complex interactions between climate and fertilizer use in shaping crop yields remain poorly understood. Focusing on winter wheat in China, this study evaluates how climate change and fertilizer use jointly influence yield dynamics using a panel data model that integrates growing degree days (GDD[0,30]), extreme degree days (EDD[30+]), precipitation, and fertilizer interactions.

RESULTS: From 1982 to 2020, winter wheat growing seasons warmed significantly (0.39 °C per decade, P < 0.01), with yields marked sensitivity to climatic shifts. A rise of 100 GDDs reduced yield by -1.7%, while 10 additional EDDs decreased yields by 0.2-1.6%. Precipitation shifts also played a role: a 50 mm increase correlated with yield changes ranging from -1.7% to +2.2%. In contrast, fertilizer application exerted a substantial positive effect, as each additional 10 kg ha[-1] of fertilizer boosted yields by 1.6-2.2%. Spatially, climate impacts were heterogeneous: northern regions saw modest yield gains (+2.7%), while southern areas experienced declines of up to -4.4%. Fertilizer use, however, consistently offset losses, increasing yields by 12.8-49.8%.

CONCLUSION: Synergistic climate-fertilizer interactions critically govern winter wheat yield responses to warming. Strategic fertilizer management can counter climate-related losses but requires location-specific optimization to avoid diminishing returns and environmental tradeoffs. These insights underscore the urgency of integrating the interaction dynamic into climate impact assessments and agricultural policy to ensure food security in a warming world. © 2025 Society of Chemical Industry.

Climate Change Does Not Directly Influence Red Squirrel (Sciurus vulgaris) Distribution in Western Europe.

microPublication biology, 2025:.

Climate change presents ongoing risks to species like the red squirrel, which, despite its wide range, faces pressures from multiple threats (fragmentation, invasive species, among others). This study assesses the relationship of red squirrel distribution across Western Europe with bioclimatic variables to predict future climate impacts. However, our results suggest that bioclimatic factors have limited predictive power, with no direct impacts identified. Indirect effects, such as the expansion of grey squirrels, may still worsen challenges for red squirrel populations. Addressing these by maintaining habitat quality and connectivity through targeted conservation measures will be crucial for ensuring red squirrel persistence.

Impact of climate change on the spread of fascioliasis into the extreme south of South America.

PLoS neglected tropical diseases, 19(8):e0013433 pii:PNTD-D-25-00382 [Epub ahead of print].

The impact of global warming on the transmission of fascioliasis, a highly pathogenic zoonotic snail-borne disease, was already highlighted during the 2010's. However, since then, only a few studies have tried to relate the climatic change with the uprise of outbreaks in endemic areas of animal or human fascioliasis. This might be because assessing the consequences of a changing climate on the spread of fascioliasis is extremely challenging, as it presents the widest latitudinal, longitudinal and altitudinal distribution known for a snail-borne disease. In the Americas, where it is only caused by Fasciola hepatica, the disease is widespread throughout the continent, except in its southernmost extremity in the Patagonia region, which was believed to be due to the too low temperatures. Though, recent empirical evidence indicates an ongoing spread of the disease into more southern latitudes. The present study aims to assess the long-term evolution of climate change factors and forecast indices throughout this extreme South American region to conclude whether their impact might have been the cause of the southward expansion of the fascioliasis endemic area. The use of seasonal-trend decomposition analyses and of spatial interpolation techniques demonstrated a remarkable climatic change in the Patagonia region allowing to clarify the southern spread of the disease. This is the first study highlighting a clear link between the consequences of a changing climate and the spread of a fascioliasis endemic area and its transmission risk to extreme latitudes. Moreover, it provides some crucial recommendations and concerns regarding the application and interpretation of two widely applied climatic forecast indices. If current climate trends persist, this geographical expansion is expected to progress further. These findings not only provide critical insight into local disease dynamics but also underscore the broader implications of climate-driven changes in the distribution of snail-borne diseases globally.

Current Marine Protected Areas Conserve Fish Spawning Aggregations Under Climate Change due to Habitat Refugia.

Global change biology, 31(8):e70433.

In addition to overfishing threats, tropical reef fishes that form spawning aggregations are threatened by climate change, which can reduce management effectiveness. While management strategies such as marine protected areas (MPAs), seasonal sales bans, and seasonal fishing closures may be effective at reducing the impacts of fishing pressure, they may not be as effective in the future as climate change reduces suitable fish habitat. By examining oceanographic conditions at known spawning sites of critically endangered Nassau grouper (Epinephelus striatus), along with future climate conditions under multiple emissions scenarios (RCPs 4.5 and 8.5), projections were made of suitable spawning habitat throughout the species' range. Spawning habitat in no-take MPAs and protected under seasonal sales bans and fishing closures was compared to spawning habitat in unprotected regions and times of year to determine potential success in protecting Nassau grouper spawning under current and future conditions. By the end of the century, declines in suitable spawning habitat were projected throughout the region under both climate scenarios. Most countries showed declines in effectively protecting spawning habitat, but MPAs had 31% higher spawning suitability than surrounding areas due to the presence of refugia with persistently suitable temperatures at the end of the century. By the end of the century, only modest improvements (≤ 10%) could be made by locating new MPAs to maximize protection of spawning sites. Additionally, spawning phenology shifts on average by 25 days under RCP 8.5, which can be mitigated in countries with seasonal bans by adjusting closures to match this change. Creating networks of smaller MPAs can maximize conservation of spawning habitat because they can incorporate climate refugia, are easier to enforce, and would protect a variety of habitats.

Climate Change Risk to Giant Panda Populations: Insights From Changes in Both Habitat Area and Bioclimatic Velocity.

Global change biology, 31(8):e70442.

Climate change affects biodiversity through multidimensional impacts, influencing not only shifts in habitat range but also changes in habitat quality. In this context, habitat area and bioclimatic velocity have become critical metrics for assessing species-specific vulnerabilities to climate change. Here, we assessed the extinction risk and exposure risk of giant pandas (Ailuropoda melanoleuca) based on habitat area and bioclimatic velocity, respectively, and examined the differences between these two risks to inform climate-adaptive conservation strategies. Our findings indicate that under the SSP2-4.5 scenario, degraded giant panda habitats are projected to total 13846.1 km[2], with the Qinling (QL), Liangshan (LS), and Daxiangling (DXL) populations experiencing substantial habitat loss of 3790.4, 2722.8, and 1135.4 km[2], respectively. Bioclimatic velocities across different populations range from -0.468 to 0.309 km year[-1], with higher velocities observed in southeastern Minshan (MS) and Qionglaishan (QLS) and Liangshan (LS) regions, suggesting potential declines in habitat suitability and substantial challenges to population survival. Our results also reveal that while most populations exhibit consistent risk patterns when assessed by both habitat area and bioclimatic velocity, notable discrepancies remain. Populations with high extinction risk generally face high exposure risk; however, some populations with low extinction risk may encounter substantial exposure risk (e.g., DXL_A and MS_K). These findings highlight the limitations of relying on single-dimensional assessments of species' vulnerability to climate change, as evidenced by the variability in risk assessment outcomes. Therefore, integrating changes in both habitat area and bioclimatic velocity provides a more comprehensive understanding of species' vulnerability, reveals local adaptation mechanisms, and offers a robust scientific basis for formulating targeted climate-resilient conservation strategies.

Genomic Insights Into Local Adaptation Across Heterogeneous Understory Habitats and Climate Change Vulnerability.

Molecular ecology [Epub ahead of print].

Understanding adaptive evolution and survival risks in understory herbs is crucial for the effective conservation of biodiversity. How environmental gradients shape species local adaptation patterns is not well understood, nor is how populations of understory herbs respond to a changing climate. In this study, we conducted population genomic analyses of Adenocaulon himalaicum (Asteraceae) with a pan-East Asian distribution, representing a good model for dominant understory herbs to elucidate adaptation mechanisms in heterogeneous forest ecosystems. Based on 34,398 putatively neutral single nucleotide polymorphisms (SNPs) across 27 populations, we identified three genetic lineages accompanied by high levels of genetic differentiation between populations. Our isolation by environment results (IBE) indicated a significant effect of environmental gradients on genomic variation of A. himalaicum (r = 0.18, p = 0.03). To decompose the relative contributions of climate, geography and population structure in explaining genetic variance, our partial RDA found that the prominent contribution of environmental effects (climatic and soil variables) explained 29% and 36% of the neutral and adaptive genetic variation, respectively. Using two genotype-environment association (GEA) methods, we identified 13 SNPs as candidates for core climate-related adaptation loci, with two of these loci further validated by qRT-PCR experiments. Projections of spatiotemporal genomic vulnerability under different future climate scenarios revealed that populations in the southeastern edge of the Himalayas, near the Sichuan Basin, the southernmost region of Northeast China and the northern Korean Peninsula, as well as northern Japan, were identified as the most vulnerable and should be prioritised for conservation. Therefore, our current study provides the genomic foundations for conservation and management strategies to elucidate how these understory herbs cope with future climate changes.

Spatiotemporal Distribution Patterns and Conservation Priorities of Gymnosperms With Different Leaf Shapes in China Under Climate Change.

Ecology and evolution, 15(8):e71980.

Leaf morphology is one of the important indicators for studying the response of plants to climate change. Gymnosperms play a crucial role in maintaining biodiversity and ecosystem stability in China. However, the geographical and altitudinal distribution patterns of gymnosperms with different leaf morphologies in China in response to climate change are not yet fully understood. This study utilized occurrence data for 71 rare gymnosperm species (including varieties) and 15 environmental variables to model the contemporary geographical distribution for the 2070s and the 2090s under two shared socioeconomic pathway scenarios (SSP2-4.5 and SSP5-8.5). Gymnosperm species were classified into five groups based on their leaf shapes (needle-shaped, scale-shaped, lanceolate-shaped, fan-shaped, and strip-shaped), and the analysis revealed that the primary climatic variable driving ecological niche differences among these groups was Bio15 (precipitation seasonality). Lanceolate-leaved gymnosperms exhibited an expansionary trend, whereas other groups generally showed range reductions under future climatic scenarios. The results indicated that approximately half of the gymnosperm species will experience notable range contractions and gradual migration to higher altitudes in northwestern regions from the present to the 2090s. Hotspots for species richness were identified in the eastern Yunnan-Guizhou Plateau, the Nanling Mountains, and the eastern Zhejiang-Fujian Hills. However, these hotspots showed limited overlap with existing nature reserves in China. The threat status of some species will be severely upgraded from vulnerable to critically endangered, such as Abies recurvata, highlighting the urgent need for enhanced conservation efforts. This study enhances understanding of the future distribution patterns of China's gymnosperms and provides valuable insights for developing targeted protection and conservation strategies.

Correlates of climate change distress: The difference to general distress.

International journal of clinical and health psychology : IJCHP, 25(3):100613.

INTRODUCTION: Climate change has significant consequences on mental health, which are summarized under concepts like eco-anxiety or climate change distress. However, these recently developed concepts still suffer from a lack of clarity.

AIM: The aim of this study is to improve the conceptual clarity of climate change distress through analysing its' correlations with various psychological and demographic factors. In this context, the specific associations of climate change distress are compared to those of general distress.

METHODS: In a cross-sectional study N = 1000 participants completed an online questionnaire. Climate change distress was assessed using the 'Climate Change - Man-Made Disaster-Related Distress Scale'. General distress was assessed using the Distress Thermometer, the Generalized Anxiety Disorder scale, and the Patient Health Questionnaire. Several measurement instruments were examined as possible correlates. The outcomes were investigated using multiple linear regression models.

RESULTS: Relevant correlates of climate change distress included trust in government to handle climate change and several emotion regulation strategies. The associated factors of general distress were distinct from those of climate change distress, such as gender and sense of coherence.

DISCUSSION: The results suggest that the correlates of climate change distress differ from those of general distress. This implies that climate change distress and general distress are two related, however distinct constructs. The associated factors can be promising targets for psychotherapy and intervention strategies.

Climate Change, Weather, and Geography Shape Seed Mass Variation and Decline Across Western North America.

Global change biology, 31(8):e70416.

Seeds are an essential reproductive strategy for most plants, and seed mass is predicted to respond to environmental factors, but we do not know if climate change-related size changes observed in other organisms will also be reflected in seed mass. We investigated the temporal, geographic, and environmental patterns that influence seed mass across 2092 species of native plants from over 13,000 locations across the western United States using information from two decades of collections from a national program, Seeds of Success. Most species exhibited low variation in seed mass, though some varied by up to 220% over their occupied area. Measures of climate change influenced seed mass in over 42% of species, which could be evidence of adaptation to new optimal values or maladaptive responses. Mean seed mass was phylogenetically conserved, while seed mass variation had little to no phylogenetic signal. Species with higher seed mass variation were collected across sites with a wider range of minimum temperatures, from more northern latitudes, and had longer growing seasons. Seeds were generally larger in warmer and wetter areas. Seed mass declined over time for 55% of species and declined overall by an average of 0.012 mg each year, though there were species-specific differences, including 19% of species increasing appreciably in mass. Seed mass of C3 and C4 species responded in opposite ways to global change metrics of temperature and precipitation, potentially providing insight into global declines in C4 species. Relationships between seed mass and environmental variables varied widely in strength, identity, and direction among species, including among congeners and species that often co-occur. These results support the need to continue native seed collections for conservation and restoration, as plant reproductive strategies may be shifting with changing climates.

Low-Carbon Agricultural Innovations Address the Challenge of Climate Change.

Plant, cell & environment [Epub ahead of print].

Climate change poses significant threats to global agriculture, compromising crop yields, livestock productivity and food security. Low-carbon agriculture (LCA) offers a sustainable pathway to reduce greenhouse gas emissions while enhancing carbon sequestration in agroecosystems. This review synthesizes LCA principles and practices, focusing on key strategies such as improving nitrogen use efficiency, optimizing water management, adopting biopesticides and leveraging artificial intelligence for resource optimization. Beyond environmental benefits, LCA supports climate mitigation, bolsters ecosystem services and fosters economic opportunities through carbon markets and sustainable value chains. However, widespread adoption requires coordinated policy frameworks, technological innovation and interdisciplinary collaboration among scientists, farmers and policymakers. We emphasize the critical role of LCA in building agricultural resilience and ensuring sustainability in a changing climate.

Climate Change Related Health Problems and Awareness of Nursing Students: A Cross-Sectional Study.

Nursing & health sciences, 27(3):e70211.

Climate change can trigger many health problems, from air quality to water resources, from food safety to infectious diseases. Developing nurses' knowledge and skills about the effects of climate change on health can make significant contributions to efforts to protect and improve public health. The aim of the study is to examine the health problems of nursing students related to climate change and determine their awareness and behaviors. This descriptive study included 386 students. Data were collected using the Individual Identification Form and the Climate, Health, and Nursing Scale. The mean age of the participants was 21.62 ± 3.89; 70% were female, and 47% were 4th-year students. Students who were informed about climate change had higher levels of knowledge, awareness, motivation, and behavior. It was concluded that students' knowledge about climate change had a positive effect on motivation and anxiety levels; while it did not have a significant effect on knowledge and awareness dimensions. Female students have higher levels of motivation and anxiety, which may play a role in shaping gender norms' sensitivity and responses to climate change.

Climate Change and Food Production: Small Millets Cultivation Ensures Global Food Supply and Nutritional Security.

Plant, cell & environment [Epub ahead of print].

Climate change poses critical challenges to universal food security, thus necessitating sustainable agricultural practices and the diversification of food crops. Given this, the present review suggests the intensification of small millet cultivation, specifically on marginal lands with limited resources, which can address nutritional and food insecurities. Owing to the superior nutritional qualities, socioeconomic advantages, and environmental benefits, integrating small millets into global food systems can essentially assist in achieving Sustainable Development Goals (SDGs) related to zero hunger, climate action, and biodiversity conservation. Key challenges, such as limited availability of genetic resources, low market incentives, and insufficient policy support, are highlighted, along with strategies for their mainstreaming through global collaborative efforts, advanced technologies, and market-efficient policy interventions. By emphasizing the unique agronomic traits of small millets, the present review underlines their potential as a sustainable alternative to current cereal crops, which provides a comprehensive solution to global environmental and food supply challenges, thus ensuring nutritional security in the face of climate change.

Adaptation and carbon reduction for petroleum contaminated soil remediation in response to climate change-a case study of phytoremediation combined with biochar.

Journal of environmental management, 393:126956 pii:S0301-4797(25)02932-9 [Epub ahead of print].

Petroleum serves as a critical energy source and industrial raw material, yet its leakage frequently leads to severe soil contamination. Traditional remediation methods for petroleum-contaminated soil are often energy-intensive and associated with high carbon emissions. To address climate change challenges, it is imperative to adopt green and sustainable remediation technologies that reduce energy consumption and carbon footprints simultaneously. Phytoremediation not only treats contamination but also captures atmospheric CO2 through biomass production, while biochar application enhances carbon sequestration through its stable structure. This study conducted a field trial to evaluate the combined effects of biochar amendment (2.5 %) and vetiver planting on total petroleum hydrocarbon (TPH) degradation efficiency and CO2 mitigation in both freshly contaminated and weathered soils. The results demonstrated that biochar application enhanced vetiver plant biomass by approximately 1.6-fold in both soil types. After six months, TPH removal efficiencies reached nearly 90 % in biochar-amended soils planted with vetiver. Furthermore, the estimated carbon reduction potential reached approximately 440.7 tons CO2e per hectare in freshly contaminated soil and 482.4 tons CO2e per hectare in weathered soil, highlighting the dual benefits of contaminant remediation and climate change mitigation.

Assessing the impacts of climate change and human activities on distribution of Lophatherum gracile in China using the maxent model.

Scientific reports, 15(1):29945.

The combined effects of climate change and human activities are reshaping species distributions, with many valuable plant species also being affected. This study uses the Maximum Entropy (Maxent) model to assess the current and future distribution of Lophatherum gracile Brongn. in China under different environmental and anthropogenic scenarios. A dataset comprising 142 occurrence records and 13 selected environmental variables, including bioclimatic, soil, and solar radiation factors, was used to predict suitable habitats. The model achieved high accuracy (AUC > 0.9, TSS > 0.7, CBI > 0.7), with precipitation during the driest month, elevation, and soil saturation identified as key factors influencing habitat suitability. The results indicate that under current conditions, L. gracile is predominantly distributed in southern China, including provinces such as Hunan, Guangxi, and Fujian. Future climate scenarios (SSP245 and SSP585) predict significant shifts in habitat suitability, with an overall reduction in highly suitable areas and a westward shift in the distribution centroid. Human activities exacerbate habitat fragmentation, resulting in a 2.18% reduction in suitable areas. These findings underscore the vulnerability of L. gracile to both environmental and anthropogenic pressures, highlighting the need for targeted conservation strategies. This research provides a scientific foundation for the conservation of L. gracile and informs adaptive management strategies to mitigate the adverse effects of climate change and human disturbance.

Habitat suitability and distribution dynamics of Rhipicephalus microplus under climate change in Yunnan Province, China.

Acta tropica, 270:107784 pii:S0001-706X(25)00255-4 [Epub ahead of print].

Rhipicephalus microplus is a significant vector of tick-borne diseases and poses serious threats to livestock health and agricultural productivity. In recent years, climate change and intensified human activities have significantly increased the risk of disease transmission. This study used the MaxEnt model and ArcGIS software to evaluate the impact of climate change on the habitat suitability of R. microplus in Yunnan Province, China. Occurrence records of the tick species and key environmental variables (such as climate factors, topography, and livestock density) were integrated to model its potential distribution under current and future climate scenarios. The results indicate that the primary environmental variables influencing the distribution of R. microplus are mean diurnal temperature range, slope, annual temperature range, annual precipitation, precipitation of the driest quarter, and cattle density. Under current climatic conditions, suitable habitats account for 80.33% of the total area of Yunnan Province. Under future climate scenarios, the overall extent of suitable habitats is projected to expand, although regional variations may occur across different periods. The distribution centroid is expected to shift southeastward, highlighting the need for enhanced tick surveillance and control in high-suitability areas in western Yunnan and newly suitable regions such as Honghe, Wenshan, and Chuxiong. These findings provide a scientific basis for developing spatially targeted strategies for preventing and controlling tick-borne diseases in Yunnan Province.

Climate change-induced eco-anxiety and asthma control in pediatric patients: A cross-sectional nursing study.

Journal of pediatric nursing, 85:285-293 pii:S0882-5963(25)00290-8 [Epub ahead of print].

BACKGROUND: Pediatric asthma remains one of the most prevalent chronic diseases affecting children globally. The rising environmental threats associated with climate change have introduced eco-anxiety as a novel psychological factor that may influence asthma control. This study aimed to investigate the relationship between climate change-induced eco-anxiety and asthma control among pediatric patients with asthma.

METHODS: This cross-sectional study was conducted among pediatric patients with asthma at the chest outpatient clinics of a public hospital in Egypt from February to May 2024. A convenience sampling technique was employed to recruit 233 participants, aged from 6 to 12 years. Data were collected through structured validated tools, including the Childhood Asthma Control Test (C-ACT) and the Hogg Eco-Anxiety Scale (HEAS-13). The data were analyzed using SPSS statistical software (version 26). Statistical analyses included Pearson's correlation and multiple linear regression.

RESULTS: Most participants (57.1 %) exhibited inadequately controlled asthma. The mean asthma control score was 18.55 (±4.57) out of 27, while the mean eco-anxiety score was 14.24 (±10.65) out of 52. A significant negative correlation was observed between asthma control and eco-anxiety (r = -0.300, p < 0.001). Regression analysis revealed that higher eco-anxiety scores, history of asthma hospitalization, family history of asthma, and having a divorced parent significantly predicted poorer asthma control (Adjusted R[2] = 0.242, p < 0.001).

CONCLUSION: Eco-anxiety is a significant psychological predictor of poor asthma control among children, particularly when compounded by sociodemographic factors such as being divorced, employee father, having a history of hospitalization for asthma, and having a family history of asthma. The findings underscore the need for pediatric nursing interventions that integrate psychological assessment and support into asthma management, emphasizing eco-anxiety as a modifiable factor to improve health outcomes.

Velocity of Climate Change and the Vulnerability of Mountain Lake Landscapes.

Environmental science & technology [Epub ahead of print].

Freshwater ecosystems in mountain landscapes are threatened by climate change. Accumulated heat can result in lethal short-term heat exposure, while velocity of change governs severity and rates of long-term heat exposure. Here, we novelly integrate heat accumulation and velocity of change approaches to classify climate-vulnerable USA mountain watersheds. We combine watershed position and air temperature data to calculate degree-days. We then calculate the current velocity of this change and used discriminant function analyses to classify watershed vulnerability through 2100. Our results demonstrate how rates of heat accumulation are increasing across mountain landscapes. We estimate 19% of watersheds are at greatest vulnerability to accumulated heat, and this will increase to 33% by 2100. Further, mean killing degree days (i.e., region-specific mean number of days above 90th temperature percentile) are projected to increase 215-254% (mean = 236%) over this same time frame. Together, results indicate heat accumulation will increase substantially over the next 75 years; changes are projected to be most severe in lower elevation landscapes and those with greatest historical velocity of change. These changes will likely restructure species' distributions. Decision-makers can use these classifications to better understand landscapes, species' needs, and ecosystem services, thereby enabling effective allocation of conservation resources.

Predicting the global invasion risk of ambrosia beetle Euplatypus parallelus under climate change based on CMIP6 projections.

International journal of biometeorology [Epub ahead of print].

Euplatypus parallelus (Fabricius, 1801) is a highly destructive invasive insect pest endemic to the Neotropics, causing economic and ecological damage to natural forests, plantations, and fruit trees. We employed the MaxEnt model to predict the global suitability of E. parallelus under current and future scenarios based on the shared socioeconomic pathways (SSPs) 126 and SSP585 in 2050 and 2070, utilizing the Coupled Model Intercomparison Project phase 6 (CMIP6) dataset. The model demonstrated remarkable performance achieving AUC values of 0.964 and 0.957, TSS of 0.841 and 0.796, and CBI of 0.967 and 0.928 during model calibration and validation, respectively. The temperature seasonality BIO4 (43.8%), annual precipitation BIO12 (31.2%), and minimum temperature of the coldest month BIO6 (14.7) were the most significant bioclimatic variables affecting the distribution of E. parallelus. The model shows that the maximum suitability of E. parallelus is primarily concentrated in Asia, Africa, and South America. Future climate change predicts a 12.85% expansion in suitable habitat areas for E. parallelus. Our predictions demonstrate that the biological suitability and global potential spread of E. parallelus would increase under the SSP126 and SSP585 scenarios in 2050 and 2070. The study findings will help the researchers, policymakers, and academicians to plan, develop, and implement effective preventive strategies to combat the spread and infestation of E. parallelus.

Climate Change and the Lāhainā Wildfires: Raising Global Awareness as Native Hawaiians.

Hawai'i journal of health & social welfare, 84(6):62-68.

On August 8th, 2023, Lāhainā, the first capital of the Kingdom of Hawai'i, experienced one of the deadliest wildfires in US history in over a century. Through historical and cultural data, the role of westernization in Maui's regional climate change is investigated. Since the 1800s, Lāhainā has fallen victim to climate-change-driven human activity. Whaling altered the ocean's carbon sink, the sugar industry diverted water from Native Hawaiian farmlands and increased carbon dioxide emissions, the opportunistic invasive, more flammable grasses predisposed the land to fire, and tourism perpetuated these harmful environmental impacts. Combined with climate change on a global scale, these factors contributed to the destruction in Lāhainā and to the physical and mental toll on its people, especially the Native Hawaiians. This manuscript's primary focus is to discuss the impact on Native Hawaiians given the deep ancestral connection with the land and the ancestry of the authors. As Native Hawaiians, this article serves as a platform for the authors' personal experiences to advocate for climate change awareness as future physicians and to emphasize inclusion of Native Hawaiians in the rebuilding of Lāhainā.

Scientific expertise in early international negotiations on climate change: Bert Bolin and the IPCC.

British journal for the history of science pii:S0007087425101052 [Epub ahead of print].

This article examines the contributions of Bert Bolin, the first chair of the Intergovernmental Panel on Climate Change (IPCC), to the collective understanding of the panel's nature, operations and results, as well as his efforts to safeguard the credibility of the IPCC process in the face of criticism. Based on the scholarship on expertise and its relationship with the political process, I argue that Bolin's contribution to that process can be summarized in three points. First, he acted as a mediator between producers of climate change knowledge and its users, in this case governments and corporations. Second, he selected and emphasized some of the information provided by the IPCC and used it to advocate for immediate action to tackle climate change. Third, he played a major role in legitimizing the IPCC as the best possible assessment organization, especially through boundary work. Additionally, it is suggested that Bolin's role in the advisory process was not static but changed within an evolving political and social context. Through this case study, I aim to contribute to the scholarship that examines how environmental problems are defined and brought into the political arena, and the role of experts in this complex process.

Potential impact of climate change on the reproductive success of grayling (Thymallus thymallus).

Journal of fish biology [Epub ahead of print].

The European grayling is a salmonid species experiencing a sharp population decline, and conservation measures have been initiated through artificial propagation. As the species is not commonly cultivated in aquaculture, there is little information on their optimal reproduction conditions. Therefore, this study has combined a two-pronged approach of examining the temperature of the natural spawning area during the spawning season, while also experimentally testing four different incubation temperatures under standardized aquaculture conditions. Nine egg clutches from pond-reared females were fertilized with a sperm mix from 10 wild grayling. Eggs were divided into four treatment groups and incubated at 6, 8, 10 and 12°C. Hatched larvae were then collected and examined for body weight, yolk-sac weight and length. Both the temperature of the natural habitat and the physiological parameters of the larvae indicate that 6 and 8°C are the optimal hatching temperatures for grayling reproduction. The hatching rate was highest at 8 and 6°C, at 80.35 ± 6.30% and 76.87 ± 8.01%, respectively, although it gradually decreased with increasing temperature. The impact of warmer water temperatures hindered survival rates, resulting in a significant decrease in hatching rates at 10°C (68.46 ± 13.85%) and 12°C (45.54 ± 27.14%).

[Impact of Climate Change and Human Activities on Net Primary Productivity of Vegetation in the Yunnan-Guizhou Plateau].

Huan jing ke xue= Huanjing kexue, 46(8):5217-5228.

Vegetation net primary productivity (NPP) is a key indicator for assessing the carbon budget of terrestrial ecosystems. Studying the impact of climate change and human activities on vegetation NPP is critical for a deeper understanding of carbon cycling mechanisms and promoting sustainable economic development. Based on MOD17A3 NPP data, meteorological data, and land use data, this study explores the spatiotemporal variation characteristics of NPP across different geological backgrounds and vegetation types in the Yunnan-Guizhou Plateau from 2001 to 2020, using the Theil-Sen Median slope estimator and Mann-Kendall significance test. An improved residual analysis method is employed to investigate the relative contributions of climate change and human activities to vegetation NPP in the Yunnan-Guizhou Plateau. The results indicated the following: From 2001 to 2020, the NPP of vegetation in the Yunnan-Guizhou Plateau showed an increasing trend at a rate of 3.39 g·(m[2]·a)[-1]. The multi-year average NPP of vegetation in non-karst areas was 901.42 g·(m[2]·a)[-1], which was higher than the 837.83 g·(m[2]·a)[-1] in karst areas. However, the growth rate of vegetation NPP in non-karst areas was 2.56 g·(m[2]·a)[-1], which was lower than the 3.69 g·(m[2]·a)[-1] in karst areas. Among different types of vegetation, herbaceous vegetation had the highest multi-year average NPP at 900.26 g·(m[2]·a)[-1], with a relatively high growth rate of 3.6 g·(m[2]·a)[-1]. Arbor vegetation had a higher multi-year average NPP of 864.54 g·(m[2]·a)[-1] but the lowest growth rate at only 2.69 g·(m[2]·a)[-1]. Economic vegetation had a lower multi-year average NPP of 809.24 g·(m[2]·a)[-1] but a higher growth rate of 3.96 g·(m[2]·a)[-1]. Precipitation contributed positively to vegetation NPP in the Yunnan-Guizhou Plateau, with a positive contribution rate of 68.16%, while temperature had a positive contribution rate of 74.5%. Precipitation significantly promoted vegetation growth in the central and eastern regions of the Yunnan-Guizhou Plateau but had a suppressive effect on vegetation in the western regions. From 2001 to 2020, climate change contributed 77.09% to the changes in vegetation NPP in the Yunnan-Guizhou Plateau, which was higher than the 22.91% contribution from human activities. Human activities had a positive contribution rate of 70.76% to vegetation NPP in karst areas, higher than the 60.96% in non-karst areas. Human activities had a larger positive contribution rate to herbaceous vegetation NPP at 73.02% and to shrub vegetation at 71.92%. The findings provide a theoretical basis for formulating tailored ecological restoration and management strategies for the Yunnan-Guizhou Plateau.

The ethics of climate change and health-care delivery: a national survey of US-based physicians.

The Lancet. Planetary health pii:S2542-5196(25)00167-6 [Epub ahead of print].

Health harms from climate change are partly driven by health-care emissions. Physician perspectives on the related ethical dilemmas of professional responsibilities, health equity, and trade-offs between individual health choices and the environmental impact of health care are not well described in current literature. We performed a cross-sectional survey of US-based physicians between July 18, 2023, and May 28, 2024 to assess related perspectives, and we analysed the results by the respondents' perceived impact of climate change on their patients' health (moderate-high impact vs no-to-low impact). 529 surveys were delivered, of which 304 (57·5%) were returned. 113 (37·4%) of 302 respondents reported that climate change had a moderate-high impact on their patients' health, whereas 249 (82·5%) respondents viewed climate change as having greater health impacts on patients with less access to health care. 105 (35·0%) of 300 respondents reported that the environmental impact of health care should be reduced even if it requires limiting treatment options of similar effectiveness. In response to hypothetical scenarios, the patients in the moderate-high impact group was more willing to place such limits (adjusted predicted probability=50%) than the no-to-low impact group (adjusted predicted probability=25%, difference=25% [95% CI 13-38]). In addition, the patients in the moderate-high impact group (adjusted predicted probability=86%) was more willing to initially trial a less effective but less environmentally toxic antihypertensive medicine than the no-to-low impact group (adjusted predicted probability=69%, difference=17% [95% CI 6-27]). A sample of US-based physicians accepted their health care-related responsibilities towards climate change and viewed its health impacts as inequitable. Perceptions of the health impact of climate change influenced willingness to accept limited treatment options for environmental reasons.

From the laboratory to the field: heat hardening shields and enhances Mediterranean mussels' physiological performance against global warming.

Marine pollution bulletin, 221:118569 pii:S0025-326X(25)01045-8 [Epub ahead of print].

Extreme marine heat wave events have increased in severity, frequency and duration, setting marine ecosystems at high risk. In this context, application of methods that can alleviate global warming devastating impacts on marine organisms constitutes a necessity. Repeated time-limited exposure of an organism to an environmental stimulus modifies its response mode, enhancing its adaptation to environmental stress. This "stress memory" effect is referred to as "hardening". The present study scoped to evaluate heat-hardened Mytilus galloprovincialis mussels' resilience to changing environmental conditions. Heat-hardened and non-hardened mussels were transferred to the field and were left to acclimatize under increasing ambient sea water temperature. Both groups of mussels were thereafter collected on 28 April, 18 June and 01 September of 2022 and a battery of biochemical indicators regarding heat shock response (HSR), energy turnover, autophagy, apoptosis and inflammation were evaluated on dissected mantle tissue. All parameters exhibited significant differences between heat-hardened and non-hardened mussels. Although heat-hardened mussels exhibited lower Hsps levels compared to the non-hardened mussels, the maintenance of hsp70 mRNA expression and Hsps levels in June and September, together with the increased mRNAs expression of electron transfer system enzymes, might provide a more efficient energy provision for the HSR. Enhanced protection and recycle of macromolecules, through HSR and autophagy, ultimately lead to the amelioration of apoptosis and inflammation, and subsequent cell survival. In conclusion, mussels' exposure to laboratory heat hardening seems to provide a "stress memory" response that enhances heat tolerance when mussels were exposed to complex natural conditions.

A Causal Inference Framework for Climate Change Attribution in Ecology.

Ecology letters, 28(8):e70192.

As climate change increasingly affects biodiversity and ecosystem services, a key challenge in ecology is accurate attribution of these impacts. Though experimental studies have greatly advanced our understanding of climate change effects, experimental results are difficult to generalise to real-world scenarios. To better capture realised impacts, ecologists can use observational data. Disentangling cause and effect using observational data, however, requires careful research design. Here we describe advances in causal inference that can improve climate change attribution in observational settings. Our framework includes five steps: (1) describe the theoretical foundation, (2) choose appropriate observational datasets, (3) estimate the causal relationships of interest, (4) simulate a counterfactual scenario and (5) evaluate results and assumptions using robustness checks. We demonstrate this framework using a pinyon pine case study in North America, and we conclude with a discussion of frontiers in climate change attribution. Our aim is to provide an accessible foundation for applying observational causal inference to estimate climate change effects on ecological systems.

Vulnerability Assessment of Six Endemic Tibetan-Himalayan Plants Under Climate Change and Human Activities.

Plants (Basel, Switzerland), 14(15):.

The Tibetan-Himalayan region, recognized as a global biodiversity hotspot, is increasingly threatened by the dual pressures of climate change and human activities. Understanding the vulnerability of plant species to these forces is crucial for effective ecological conservation in this region. This study employed an improved Climate Niche Factor Analysis (CNFA) framework to assess the vulnerability of six representative alpine endemic herbaceous plants in this ecologically sensitive region under future climate changes. Our results show distinct spatial vulnerability patterns for the six species, with higher vulnerability in the western regions of the Tibetan-Himalayan region and lower vulnerability in the eastern areas. Particularly under high-emission scenarios (SSP5-8.5), climate change is projected to substantially intensify threats to these plant species, reinforcing the imperative for targeted conservation strategies. Additionally, we found that the current coverage of protected areas (PAs) within the species' habitats was severely insufficient, with less than 25% coverage overall, and it was even lower (<7%) in highly vulnerable regions. Human activity hotspots, such as the regions around Lhasa and Chengdu, further exacerbate species vulnerability. Notably, some species currently classified as least concern (e.g., Stipa purpurea (S. purpurea)) according to the IUCN Red List exhibit higher vulnerability than species listed as near threatened (e.g., Cyananthus microphyllus (C. microphylla)) under future climate change. These findings suggest that existing biodiversity assessments, such as the IUCN Red List, may not adequately account for future climate risks, highlighting the importance of incorporating climate change projections into conservation planning. Our study calls for expanding and optimizing PAs, improving management, and enhancing climate resilience to mitigate biodiversity loss in the face of climate change and human pressures.

Climate change-driven northward expansion of the mediterranean orchid Ophrys apifera from genetic and ecological perspectives.

Scientific reports, 15(1):29634.

Ophrys apifera, commonly known as the bee orchid, is a species of orchid that has expanded its range northwards in recent decades. The present study focuses on its occurrence in Poland and analyses possible causes of this expansion, including climate change, autogamy and genetic diversity of new populations. Genetic analyses using nuclear microsatellite markers and plastid DNA revealed low overall population variability in Poland and neighbouring countries (the Czech Republic, Germany), probably caused by the founder effect and bottleneck, as well as the autogamous reproductive strategy of this species. STRUCTURE analysis identified three genetic clusters, with western populations forming a distinct, homogeneous cluster, while southern populations show a greater degree of genetic mixing. Plastid haplotype diversity was limited, with most populations dominated by a single haplotype. This confirms the scenario of recent colonisation through long-distance seed dispersal. Ecological niche modelling indicates that although O. apifera will continue to spread in regions with a suitable climate in northern and central Europe, habitat loss due to rising temperatures is predicted in the southern and western parts of its range. The combination of genetic and ecological data suggests that several independent colonisation events contributed to the recent spread of O. apifera. These findings highlight the importance of monitoring genetic variation in newly established populations and further investigating the role of climate change in the range shift of orchids.

Optimizing sustainable and multifunctional management of Alpine Forests under climate change.

Scientific reports, 15(1):29761.

Climate change is challenging the sustainable provision of biodiversity and ecosystem services in mountain forests, including the important protection service against gravitational natural hazards. Forests offer a relatively cost-efficient measure to protect humans and infrastructure from natural hazards. Forest managers are faced with the question of how to adapt their forest to climate change and optimally manage their forests to guarantee future forest multifunctionality. Usually, alternative close-to-nature forest management strategies can be implemented, but individual management objectives and forest resilience affect the optimal portfolio of management strategies. To address this planning task, we used the climate-sensitive forest growth model ForClim and developed a tailored multi-objective optimization method, considering particularities of forests with a protection service. We applied the method in an Alpine forest enterprise in Switzerland. We combined three climate change scenarios with three optimization scenarios. Our results show that a diversified and optimized portfolio of management strategies can safeguard and improve the provision of multiple ecosystem services and biodiversity concurrently. However, given the increasing intensity of climate change, a greater share of climate-adapted close-to-nature forest management strategies is necessary, reaching 78% in forests without a protection service and 68% in forests with a protection service under severe climate change and optimized for multifunctionality. Adaptation also enabled further improvement of biodiversity and ecosystem service provision, particularly for carbon sequestration. The presented simulation and optimization framework, tailored for mountain forests with a protection service, shows flexibility in the integration of management objectives, making it useful for decision support. Forest management planning should rely more on and make use of such frameworks to help support forests under the uncertainties of climate change and to achieve the future political ambitions of multifunctionality and climate resilient forest ecosystems.

Formation of three great Asian plateaus, climate change, and biodiversity.

Trends in ecology & evolution pii:S0169-5347(25)00192-2 [Epub ahead of print].

The Qinghai-Tibet, Iran, and Mongolia plateaus constitute the largest continuous mountain belt on Earth and harbor the world's richest temperate alpine ecosystem, but the original timing and evolutionary causes of their biodiversity are poorly understood. Here, we review the geologic and phylogenetic evidence and compare it with the formation processes of the three plateaus. We show that the formation of the three plateaus is a major driver for change in the Asian landscape and biotas. Among the three plateaus, the Qinghai-Tibet Plateau has the most ancient evolutionary history and hosts the oldest biotic components and the highest biodiversity. The Neogene was a period of marked diversification across the three plateaus, thus leading to the formation of modern biotas.

Environmental fate of POPs under climate change: Regulation of POPs distribution by soil organic matter and microbial communities during glacial retreat.

Environmental pollution (Barking, Essex : 1987), 384:126983 pii:S0269-7491(25)01356-9 [Epub ahead of print].

Glacial retreat zones are highly sensitive to climate change. This makes them unique models of vegetation succession that reflect interactions among soil development, microbes, and the behavior of chemicals. In this study, the fate of persistent organic pollutants (POPs) during soil succession in glacial retreat areas was investigated, with a focus on the roles of soil organic matter (SOM) and microbial communities. Network analysis and partial least squares structural equation modeling were combined to quantify environmental and biological factors influencing POPs distribution. The grey evaluation method and Radial Basis Function Neural Network were applied to uncover coupling effects on POPs fate. Based on the results, there is a significant influence of microbial diversity and organic carbon stability on POPs stabilization. Stable mineral-associated organic carbon (MAOC) pools act as a "stable anchor" for highly hydrophobic POPs by inhibiting carbon turnover rates, while rapid cycling of reactive carbon pools governs the ecological equilibrium of certain POPs. The redistribution and sequestration of POPs are controlled by microbial pathways for MAOC stabilization. This study provides novel insights into how biotic-abiotic factors dominate the long-term distribution mechanisms of POPs, offering valuable perspectives on their fate under climate change.

Climate change will make increasing people less comfortable: Insights from the weather preference index.

Journal of environmental management, 393:126949 pii:S0301-4797(25)02925-1 [Epub ahead of print].

Climatic comfort profoundly influences human health and overall quality of life. In the context of global climate change, understanding future trends in climatic comfort is crucial for addressing climate challenges and advancing global sustainable development. This study assessed the impacts of future climate change on global climatic comfort using the Weather Preference Index (WPI). The results indicated that climatic comfort will exhibit a worsening trend from 2020 to 2100, with the WPI decreasing from 2.03 in 2020 to 1.85 (1.61-1.95) by 2100. The primary driver of this decline was the increase in summer daily maximum temperature. Consequently, the global population exposed to worsening climatic comfort is expected to grow from 488 million historically to 3685 million in the future, marking a 6.6-fold increase. Urban populations will see a 5.6-fold growth, while rural populations will experience a more pronounced increase of 8.1-fold. Furthermore, the transition from a relatively optimistic to an extreme emissions scenario (SSP1-2.6 to SSP5-8.5) will exacerbate climatic discomfort, exposing even more populations to worsening climatic comfort. These findings underscore the urgent need for global policy intervention, advocating for integrated climate adaptation and mitigation strategies to effectively counteract the worsening climatic comfort and enhance the resilience of human settlements.

Legume integration in smallholder farming systems for food security and resilience to climate change.

PloS one, 20(8):e0327727.

A random sample of 847 households (HHs) in southern Ethiopia was used to assess the impact of HH characteristics, land and livestock ownership, seasonal variations, and agricultural challenges on cereals and legumes, crucial to community livelihoods. A structured survey was integrated into the ODK data collection tool, validated, and used with trained agricultural agents, and analyzed using an R statistical package. Farm productivity was significantly influenced by gender, since male headed HHs produced 25.5% more yield than female headed HHs. Livestock ownership, land cultivation, farm productivity and product utilizations were also varied among the HHs. Furthermore, agricultural practices like labor utilization, fertilizer and composite application, and use of improved seed varieties significantly affected the farm productivity. Besides, maize was identified as the principal and top-priority crop, while common bean (legume) was the second-priority crop for local people. This shows that legumes were important in the region's agricultural systems, but some farmers experienced reduced productivity due to poor agronomic practices. Consequently, a substantial proportion of farmers (>50%) faced food shortages from February to June, representing the peak of the dry season and the beginning of the rainy season (April to May). Integrating early-maturing legumes in the farming system would help to escape the food shortage periods. Many farmers disclosed that the cost of chemical fertilizers' was unaffordable, indicating a need for options like use of rhizobia inoculants and showed interest to use on their farms for improved productivities.

Excess water availability in northern mid-high latitudes contiguously migrated from ocean under climate change.

Science advances, 11(33):eadv0282.

Terrestrial water availability sustains livelihoods, socioeconomic development, and ecosystems. Despite an understanding of contributions of oceanic moisture to terrestrial hydroclimatic extremes, whether surpluses of terrestrial water availability migrate directly and contiguously from the ocean and the influence of climate change on this process remain unclear. Here, we use a coherent feature-tracking method to identify ocean-to-land water availability surpluses (OWASs), characterized by spatiotemporally contiguous migration of excess atmospheric freshwater (precipitation-minus-evapotranspiration) from ocean to land. Over the past several decades, especially in northern mid-high latitudes (NMHL; above 48°N), OWASs have exhibited longer persistence, wider areal extent, and greater intensity than those developed solely over land. These landward migrations are associated with seasonal Atlantic teleconnection and Pacific circulation shift. Under the business-as-usual scenario, these two processes are projected to be enhanced, markedly increasing OWAS characteristics in NMHL driven by thermodynamic atmospheric responses to future warming. Intensified OWASs may not only help alleviate long-term droughts but also have the potential to accentuate pluvial risks.

Hotter Nights, Hidden Consequences: An Overlooked Dimension of Climate Change.

Integrative and comparative biology pii:8233668 [Epub ahead of print].

Global temperatures are shifting in complex ways due to climate change. While early research focused on rising mean temperatures and its effect on biological outcomes, recent work has shifted toward understanding the influence of temperature variability. In particular, many studies investigate temperature variation by symmetrically expanding daily temperature ranges around a fixed mean or by increasing daytime maximums. Although these approaches isolate specific aspects of temperature change, they often fail to capture how climate change is actually reshaping daily temperature cycles. In this perspective paper, we use climate data across three geographic scales to illustrate a striking and consistent pattern: daily minimum temperatures are rising faster than daily maximums, effectively reducing daily temperature range. A global analysis reveals that nighttime minimum temperatures are increasing more rapidly than daytime maximums across most land areas worldwide, especially at higher latitudes and elevations. At the continental scale, North American climate data show that asymmetric warming occurs year-round, with the strongest effects in winter. Regional patterns reveal especially strong nighttime warming in mountainous regions like the Rocky and Pacific Mountain systems. Locally, hourly data from Paradise, Nevada show nighttime temperatures have risen by over 4°C since the 1950s, while daytime highs remained stable, reducing daily temperature range by more than 4°C. We then synthesize findings from 84 studies that directly investigated biological responses to nighttime warming. Nearly half (47%) of the orders studied were plants, highlighting major taxonomic gaps in animal and microbial systems. Most studies (57%) were in organismal biology, yet few were hypothesis driven. Across taxa, asymmetric warming alters energetics, increases metabolic costs, and affects both thermal performance traits (e.g., metabolism, activity) and threshold-dependent traits (e.g., phenology, sex determination). We highlight evidence that nighttime warming may enhance or inhibit cellular recovery from heat stress (Heat Stress Recovery Hypotheses), shift species interactions, disrupt pollination networks, and reshape community structure. We conclude with a call for broader research across taxa, life stages, and ecological contexts, and recommend experimental, field-based, and modeling approaches tailored to disentangle the unique effects of asymmetric warming. Understanding asymmetric warming is not just a research gap-it's a pressing ecological imperative essential for predicting and mitigating climate change impacts on biodiversity.

The mean number of months with patients developing symptomatic infection with Babesia microti rose from 2.2 before 2000 to 9.2 after 2015. In the climate change era, babesiosis should be considered in the differential diagnosis of patients presenting with fever and anemia outside of peak summer months.

Mapping climate change-driven epidemics.

Frontiers in epidemiology, 5:1605058.

The recent analysis by Mora and colleagues revealed that over 277 diseases can worsen due to climatic hazards resulting from greenhouse gas emissions. Specifically, more than 58% of known human diseases can be aggravated by climate change. Furthermore, there are over 1,000 pathways through which various climatic hazards have contributed to disease outbreaks, primarily due to the diversity of pathogens. This analysis also urges immediate action to address the root of the problem-reducing greenhouse gas (GHG) emissions. Numerous climatic hazards affect the incidence of human pathogenic diseases. Unfortunately, due to the complexity and multifaceted nature of the problem, there cannot be a single comprehensive solution to minimize climate-driven outbreaks. This study seeks to identify outbreaks of specific diseases categorized as epidemics, whose incidence is strongly correlated with global warming. The focus of this analysis is on (1) organizations responding to climate-related diseases to decelerate the incidence rates; (2) to call for a new disciplines in epidemiology that focuses exclusively on climate change-related prediction for future pandemics; (3) looking at the problem from the patient's point of view-how do non-medical/health professionals contribute to minimizing the spread of climate-related diseases?; (4) to analyze outbreaks vs. urbanization/pollution/increase in population density and public health policies; also (5) to verify the vaccination coverage vs. case reduction rate.

Determinants of Fruit Tree Adoption as a Climate Change Adaptation Strategy Amongst Smallholder Farmers in Lake Kyoga Basin: A Case Study of Budaka District, Eastern Uganda.

TheScientificWorldJournal, 2025:9642641.

This study investigated the socioeconomic determinants of fruit tree adoption amongst smallholder farmers in Budaka District, Eastern Uganda. Specific objectives included describing the characteristics of fruit tree gardens, mapping their spatial distribution, and analysing socioeconomic factors influencing adoption. This study is one of the first empirical studies in agroforestry to relate socioeconomic factors in Eastern Uganda to the spatial distribution of fruit trees. The study employed a combined approach incorporating GIS-based spatial mapping and socioeconomic analysis. A cross-sectional design was employed, with data collected from 276 randomly selected farmers, key informants, and focus groups. GIS was used to visualise the spatial patterns and descriptive statistics, and chi-square tests were applied to identify differences between adopters and nonadopters. Results indicated that fruit farming is predominantly undertaken by males aged 40 and above. Fruit tree distribution is concentrated in the north and northwest, grown on small holdings averaging 0.5 acres with 10-40 trees. Chi-square tests confirmed significant differences in age, labour type, farm size, and income between adopters and nonadopters, whilst there were no significant differences in gender, family size, and access to credit. Policy interventions should expand youth- and gender-inclusive extension services that support climate resilience and sustainable fruit tree farming, and address land tenure limitations to increase adoption.

Climate change policies fail to protect child health.

Globalization and health, 21(1):47.

BACKGROUND: National policies are essential for countries to adapt to the negative health impacts of climate change. Children are disproportionately affected by these impacts and must be at the heart of adaptation policies to address their vulnerabilities. Adaptation commitments worldwide are integrated into national adaptation plans, nationally determined contributions, national communications, and other multisectoral policies. We aimed to evaluate how effectively national climate change policies worldwide plan to protect child health, considering a range of determinants for successful child-health adaptation.

METHODS: We collated each country’s most recent national climate change adaptation plan published up to 12 July 2024. We created a checklist to assess how effectively policies were designed to protect child health, considering five determinant areas: policy background, goals, resources, monitoring & evaluation, and implementation. We assigned each policy quality categories (weak, needs improvement, or strong) for each determinant area, and an overall score (0–23) based on how many items were achieved from the checklist.

RESULTS: National adaptation policies worldwide had poor planning to adapt to the harms climate change will cause child health, with 43% not mentioning child health at all. Around half acknowledged the disproportionate impacts of climate change on children, but most did not specify these impacts. Twenty-seven per cent of countries described goals and/or actions to promote child health but lacked clear targets for success. Seven per cent outlined monitoring and evaluation mechanisms, but none measured child health outcomes directly. Twelve per cent involved multiple stakeholders in policy implementation but rarely described their obligations.

CONCLUSIONS: The design of national policies must be strengthened to protect child health from the harms of climate change. Policies should explicitly acknowledge children and their unique health risks. Goals should be both time- and age-sensitive with clear health targets, accompanied by actions that holistically address child health risks in the region concerned. A clear strategy for resource allocation and mobilisation will improve the success of policy actions. These interventions should be monitored and reviewed regularly to facilitate continuous adaptation to the changing climate. Multi-level stakeholders must be involved in policy design, and their responsibilities defined to improve implementation success.

Implications for the distributional range of the European bark beetles under future climate change.

Scientific reports, 15(1):29556.

The European continent is rich in forest resources, with bark beetles being the most significant biological disturbance impacting European forest ecosystems. Over the past few decades, many trees have died due to bark beetle infestations, causing considerable economic damage to forestry. It is estimated that climate change will affect the distributional range of bark beetles, increasing the risk of outbreaks. However, the ability of different beetle populations to respond to climate change remains unknown. For this purpose, we selected nine species of bark beetles commonly found in Europe and constructed the MaxEnt model to simulate the distribution pattern of bark beetles under climatic conditions based on 21 environmental variables. Modeling projected changes in the distribution of different species of bark beetles under four climate scenarios for 2081-2100 using future climate variables and testing the hypothesis that narrow-ranged species are more vulnerable to climate change than wide-ranged species. The results show that the distribution of most bark beetles is influenced by temperature-related variables. With climate change, the suitable distribution areas for most species will expand and gradually shift to higher latitudes. Furthermore, most of northern Europe will be invaded by multiple bark beetle species in the future. These findings contribute to understanding the distributional dynamics of bark beetles in Europe under climate change, thereby facilitating the development of early-intervention strategies to reduce the risk and impact of species outbreaks.

Physical Activity and Climate Change: A Content Analysis of National Adaptation Plans for Climate Adaptation for Low- and Middle-Income Countries.

Journal of physical activity & health [Epub ahead of print].

BACKGROUND: Climate change and physical inactivity are significant health challenges. While physical activity's role in climate change mitigation is recognized, its contribution to climate change adaptation remains underexplored. This study aimed to identify physical activity in National Adaptation Plans (NAPs) for low- and middle-income countries and common sectors benefiting climate change adaptation and promoting physical activity.

METHODS: This study used the United Nations Framework Convention on Climate Change "NAP Central" registry, analyzing 50 NAPs from low- and middle-income countries adopting a summative/conceptual content analysis approach. Data collection consisted of identifying keywords related to physical activity and built environments in the NAPs, analyzing sectors related to the keywords to assess their role in climate change adaptation.

RESULTS: Summative content analysis of 50 NAPs found "transportation" as the keyword most mentioned (N = 41) across all income categories and "sidewalk" and "walkability" being least mentioned (N = 3 each). "Sport" was the most common among physical activity keywords (N = 8), followed by "cycling" (N = 4) and "physical activity" (N = 3). "Physical conditioning" and "exercise" were the least mentioned (N = 1 each). The "transportation" sector prevailed (N = 33), contrasting with "health," the least prevalent sector (N = 7). Most countries targeted 2030 for NAP goals (n = 41). Conceptual content analysis stressed transportation planning, green spaces, and active transportation in climate adaptation.

CONCLUSION: As climate change continues to accelerate, synergistic strategies addressing physical activity and climate change are needed. Further studies are crucial to explore NAP implementation and evaluation in low- and middle-income countries, enhancing understanding of climate change adaptation's impact on health and physical activity.

Journal of environmental management, 393:126951 pii:S0301-4797(25)02927-5 [Epub ahead of print].

Using antibiotics in livestock farming has raised serious concerns, particularly about greenhouse gas (GHG) emissions and the discharge of residual antibiotics from livestock carcasses (LSC). Due to the low C-to-N ratio (≤4.4) and persistent antibiotic residues post-rendering, dead livestock are not suitable for conventional treatments such as composting and anaerobic digestion. This study presents a thermochemical conversion strategy using carbon dioxide (CO2) as a mild oxidant. CO2 facilitated gas-phase reactions with pyrolytic volatile matter, shifting carbon distribution toward valuable syngas production and minimising unwanted condensable products. Multi-stage pyrolysis yielded only modest gains due to reaction rate limitation, catalytic pyrolysis with a Ni-based catalyst increased syngas production to 25.91 mmol g[-1] under CO2 (an increase of 28 % over N2 conditions). CO2 contributes to the degradation of polycyclic aromatic hydrocarbons (PAHs) and residual antibiotics, improving the environmental safety of the pyrolysis process. The CO2-assisted pyrolysis had a lower carbon footprint (-0.42 g CO2-eq g[-1]), compared to landfilling, which had higher emissions (16.48 g CO2-eq g[-1]). These findings reveal a carbon-negative, resource-efficient method for safely and sustainably treating antibiotic-contaminated carcass waste.

Climate change and the global food chain: a catalyst for emerging infectious diseases?.

International journal of emergency medicine, 18(1):149.

BACKGROUND: Climate change is disrupting the global food chain, affecting food production, delivery and safety. Extreme weather events disrupt the quality of food and water, while rising temperatures accelerate the spread of microbes. Habitat destruction also forces wildlife in close proximity to people, increasing the risk of zoonotic diseases. Threatening global health seriously, these disturbances also increase the probability of infectious and food-borne diseases.

METHOD: A narrative review of literature data from WHO publications, Google Scholar and PubMed. The review examines the impacts of climate change on agriculture, food supply systems, and the associated transmission of infectious disease - specifically zoonotic and food-borne diseases.

RESULTS: As temperatures increase, the germs multiply easily - and the risk of E. coli and Salmonella goes up. Waterborne diseases such as Norovirus and Hepatitis A are more likely to spread in typified extreme weather conditions such as floods. Ecosystem changes push humans and animals into a closer relationship that can lead to zoonotic spillovers, such as the Nipah virus and COVID-19. The growth of animal production and international trade exacerbates antimicrobial resistance (AMR) issues, imposing challenges to disease control.

CONCLUSION: Climate change is a critical public health emergency with risks of zoonotic and food-borne illnesses alarmingly on the rise. This is an important step toward a One Health approach, which also addresses the integration of human, animal, and environmental health, as well as strengthens food safety regulations and enhances disease surveillance. It needs immediate international cooperation to construct a robust and sustainable food system that reduces health hazards.

Sustained benefits of long-term biochar application for food security and climate change mitigation.

Proceedings of the National Academy of Sciences of the United States of America, 122(33):e2509237122.

Biochar application offers significant potential to enhance food security and mitigate climate change. However, most evidence stems from short-term field experiments (≤3 y), leaving uncertainty about the long-term sustainability of these benefits, especially with annual biochar additions to soils. To address this knowledge gap, we analyzed a global dataset from 438 studies (3,229 observations) and found that long-term annual biochar application (≥4 y) not only sustains but often enhances its benefits. These include improved crop yields (+10.8%), reductions in CH4 (-13.5%) and N2O (-21.4%) emissions, and increased soil organic carbon content (+52.5%). In contrast, these benefits tend to diminish over time with single biochar applications due to the aging effect of biochar. Results from 29 global long-term experiments (4 to 12 y) confirm these sustained benefits for crop yield and greenhouse gas mitigation, although the magnitude of effects varies with soil properties, climate, and management practices. To maximize biochar's long-term benefits for global food security and climate change mitigation, it is essential to develop viable strategies, such as applying biochar at intervals of several years while tailoring practices to local soil, climate, and cropping conditions.

Climate change and Vibrio: Environmental determinants for predictive risk assessment.

Proceedings of the National Academy of Sciences of the United States of America, 122(33):e2420423122.

Climate change significantly impacts the incidence and abundance of microorganisms, including those essential for environmental cycles and those pathogenic to humans and animals. Shifts in conditions favorable for microbial growth have expanded the geographic range of many pathogens, contributing to the emergence and reemergence of infectious diseases. Waterborne diseases pose severe risks in regions where adverse climate conditions intersect with population vulnerabilities, especially inadequate water, sanitation, and hygiene infrastructure. Since many waterborne pathogens play crucial roles in the environment, such as in carbon and nitrogen cycling, their eradication is not possible. However, predictive intelligence models that identify environmental heuristics conducive to the growth of pathogenic strains, integrating microbiological, sociological, and weather data, can offer anticipatory decision-making capabilities, reducing infection risks. Here, the objective was to analyze data from studies since the 1960s to identify environmental determinants driving the occurrence and distribution of pathogenic Vibrio spp., enabling predictive modeling of the effects of climate change on cholera and noncholera vibriosis. The proliferation of Vibrio spp. in aquatic ecosystems has been linked to climate change and, concomitantly, with increased environmental disease transmission, notably cholera in Southeast Asia and parts of Africa and noncholera vibriosis in Northern Europe and along the Eastern seaboard of North America. Global predictive risk models for Vibrio cholerae have contributed to reduction in case fatality rates when coupled with individual and large-scale intervention early in outbreaks. These models, when appropriately modified, hold the potential to predict disease caused by all clinically relevant Vibrio spp. and other waterborne pathogens.

Interventions addressing impacts of climate change on sexual and reproductive health and rights in sub-Saharan Africa: A scoping review.

PloS one, 20(8):e0329201.

Sub-Saharan Africa is faced with triple challenges of high vulnerability to climate change impacts, high levels of inequality, and poor sexual and reproductive health and rights (SRHR) outcomes. Climate change impacts can worsen the SRHR situation for high-risk groups such as women, children, adolescent girls, and people living with Human Immunodeficiency Virus (HIV). This scoping review examined interventions addressing the impacts of climate change on SRHR in the region to identify barriers to and facilitators of effective integration. The review followed Arksey and O'Malley's framework for scoping reviews. Data search was conducted in peer-reviewed journal databases and from grey literature on the official websites of selected organizations. Data charting was conducted using the Population, Intervention, Comparator, Outcome tool in Covidence. There is limited evidence on interventions at the intersection of climate change and SRHR, with seven (7) documents included in the review. Maternal and Child Health, HIV prevention, and a combination of maternal and child health and family planning were the SRHR components addressed. Other components like Gender-based violence, harmful practices, and abortion care do not have targeted interventions. A siloed approach to SRHR and climate change programming impedes intervention integration. Documented interventions are implicit about climate risks, focus on impact pathways, and do not directly target SRHR. There are no interventions targeting vulnerable and marginalized groups. Limited policy integration, financial constraints, and poor SRHR recognition deter intervention integration. Effective and equitable integration requires that population growth impacts and SRHR issues be recognized and deliberate investments (research, policies, programs, interventions, and financing) put in place to address critical SRHR gaps and climate vulnerabilities to enhance resilience.

Climate change and ocular health: temperature-pollution synergies amplify uveitis burden.

Frontiers in public health, 13:1650255.

BACKGROUND: Uveitis, an inflammatory eye disease, exhibits seasonal patterns, which suggest environmental influences. This study examines the link between average temperature and uveitis outpatient visits, considering air pollution's modifying effects.

METHODS: We analyzed uveitis outpatient data (n = 8,090) from a major hospital in Shanghai between 2017 and 2023, along with meteorological and air pollutant data. A distributed lag non-linear model (DLNM) was used to assess the associations between temperature and outpatient visits, adjusting for humidity, pollutants, and temporal factors.

RESULTS: A non-linear relationship exists between temperature and uveitis visits. Lower temperatures increased visits, with peak relative risk at -4°C lagged by 1 day (RR = 1.351, 95%CI: 1.069-1.706). Significant associations were found at lags 0-1 and 12-14, with the highest risk at lag 14 (-4°C, RR = 1.257, 95%CI: 1.113-1.420). Stratified analyses showed stronger associations in males and individuals under 60 years. High humidity and elevated PM2.5 levels strengthened the cold temperature association, while extremely high temperatures (33-34°C) increased visits under low humidity (RR = 2.625, 95%CI: 1.034-6.668 at 34°C).

CONCLUSION: Temperature extremes are linked to increased uveitis outpatient visits in Shanghai, particularly with cold temperatures in high-humidity and high-PM2.5 environments, and hot temperatures under low humidity.

Extinction Risk Assessment and Conservation of the Pachypodium Under Climate Change.

Ecology and evolution, 15(8):e71926.

Global climate change poses unprecedented challenges to the maintenance and survival of biodiversity, with endemic species in particular regions facing an exceptionally high risk of extinction. Pachypodium, a genus endemic to South Africa and Madagascar, exhibits strong habitat specificity, yet the impacts of climate change on its distribution patterns remain not fully understood. This study employs the Biomod2 package in R to predict changes in the distribution patterns of 20 Pachypodium species under climate change scenarios (SSP2-4.5 and SSP5-8.5). Additionally, machine learning methods have been applied to assess the extinction risk of these species. The results indicate that climate change will severely impact the distribution of the genus Pachypodium. Suitable habitat areas for 15 species within the genus are projected to shrink significantly in the future, with the most pronounced habitat loss occurring in central and eastern Madagascar, eastern Namibia, and central and northern South Africa. Annual precipitation and precipitation seasonality are the main factors influencing these habitat changes. A reassessment of the IUCN categories for Pachypodium reveals that the number of threatened species will increase from 7 to 13. Alarmingly, three species are predicted to face a risk of extinction in the wild due to climate change. Moreover, the current protected areas have proven ineffective in safeguarding the habitats of Pachypodium, with protected habitats expected to decrease by 30.39% under the influence of climate change. These findings provide strategic insights for the conservation of Pachypodium species and highlight the necessity for reforms and adaptive adjustments to current protected area networks to address the challenges posed by climate change.

Alarming implications: severe fever with thrombocytopenia syndrome and its biological vectors in the context of climate change.

Frontiers in microbiology, 16:1544427.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne zoonotic disease. Since its identification in China in 2009, reports of SFTS cases have steadily increased, posing a significant threat to public health. This review summarizes the epidemiological characteristics of SFTS and its biological vectors, with a particular emphasis on the role of the tick vector Haemaphysalis longicornis in disease transmission. We also addressed the impact of climate change on the spread of SFTS and its biological vectors. With continued climate change, the spread of SFTS is likely to increase, consequently heightening the risk of infection. Furthermore, this review explores the prevention and control strategies for SFTS as well as future research directions, summarize the public health policies and the alleviation of the disease's impact on human health.

The significance of climate policy stringency, environmental taxation, and public debt in addressing climate change challenges.

Journal of environmental management, 392:126924.

This study aims to explore the role of the three types of climate policies (sectoral, cross-sectoral, and international), public debt, and environmental taxation in reducing the greenhouse gases emissions in selected OECD countries between 1995 and 2023. The significance of the study stands in demonstrating the different effects of various instruments in mitigating the climate change. The methodological framework includes fully modified and dynamic OLS models (FMOLS-DOLS) and confirms the robustness of the findings using Driscoll-Kraay estimation regression and Lewbel two-stages least square estimator. In the context of SDG-13, the main results attest the significant influence environmental policy stringency have for mitigating climate change and argues for the usefulness of environmental fiscal instruments. Additionally, the results highlight a marginal effectiveness of public spending for environmental purposes and controls the whole picture by confirming the damaging role of economic growth and urbanization. Furthermore, the research offers novel insights into the environmentally harmful effects of public debt. Based on these original results, the policy recommendations lean towards stricter environmental regulations and carbon fees that can ultimately finance climate actions without affecting public debt, which is also seen as harmful for effectively mitigating environmental issues.

Impact of climate change on the distribution of Tityus scorpions (Buthidae) in the Amazon: Implications for conservation units and indigenous territories.

Toxicon : official journal of the International Society on Toxinology, 266:108532 pii:S0041-0101(25)00307-1 [Epub ahead of print].

Climate change is altering the distribution of organisms, affecting ecosystem goods and services. These impacts can pose new challenges for public health due to shifts in the distribution of venomous animals, influencing the dynamics of envenomation incidents. The consequences of climate change are expected to be more severe in tropical regions, where the most vulnerable communities are located. In this context, the increase of scorpionism in recent decades across the vast Amazonian region of Brazil calls for an assessment of future risks. In this study, we analyze the effects of climate change by the year 2070 under different future scenarios (SSP2-4.5 and SSP5-8.5) on the distribution of the three most medically important scorpion species in northern Brazil: Tityus obscurus, T. metuendus, and T. silvestris. Additionally, we quantify the impact of these changes on conservation units and Indigenous territories. Our results indicate that the three species will respond differently to climate change. Tityus obscurus is projected to undergo a significant range contraction, T. silvestris will experience minimal changes, and T. metuendus will likely expand significantly into new areas. As a consequence of these shifts, T. obscurus may lose a large portion of its range within conservation units, potentially compromising the biotechnological potential of its venom. On the other hand, T. metuendus is expected to expand significantly into Indigenous territories, bringing new challenges to public health. Thus, climate change may have direct impacts on the health of the most vulnerable populations and on the conservation of species in northern Brazil, highlighting the need for strategic measures to mitigate these effects.

The fern Nephrolepis exaltata is largely unresponsive to climate change conditions at both physiological and metabolic levels.

The Plant journal : for cell and molecular biology, 123(3):e70397.

Climate change is impacting the performance of plants worldwide. However, the impact on ferns, the second-most diverse lineage of vascular plants, has received little attention. Here, we investigated the effects of one of the most claimed scenarios of the climatic change: drought (D), high temperature (HT) and high CO2 concentration (HCO2) on a fern (Nephrolepis exaltata) and a commonly studied angiosperm (Brassica oleracea) at photosynthetic, anatomical, and metabolic levels. Leaf anatomy was slightly affected by stress conditions in both species. Multivariate analysis demonstrated that B. oleracea's physiological responses to HCO2 were greater than N. exaltata's. Lipids and primary metabolites levels differed in response to stress in B. oleracea. Notably, the combination of D, HT, and HCO2 exacerbated the changes in primary metabolites, reducing amino and organic acids levels. Interestingly, phosphatidylcholine and phosphatidylethanolamine levels showed varied responses, increasing under HT and decreasing under HCO2 or combined stress in B. oleracea. In contrast, the fern was mostly unresponsive to D, HT, HCO2, and the combination among them at the metabolic level. Beyond providing important information concerning the trade-off between carbon uptake and stress acclimation mechanisms, our study indicates minor fern responses to D, HT, HCO2, suggesting differential impacts of climate change on ferns and angiosperms.

Forecasting impacts of climate change on barking deer distribution in Pakistan.

Scientific reports, 15(1):29035.

Climate change is a significant driver of biodiversity loss impacting an estimated 15-30% of known species by the end of the 21st century. We assessed current suitable habitat and projected future distribution of barking deer (Muntiacus vaginalis) across three climate change scenarios (SSP1-2.6, SSP2-4.5, and SSP5-8.5) in northern Pakistan using 99 occurrence records from remote camera during 2021-2023. We obtained bioclimatic data for current (1970-2000) and future (2041-2060, 2061-2080, 2081-2100) periods from the WorldClim database using the Hadley Global Environment Model (HadGEM3-GC31-LL). We used MaxEnt software to predict current and future distributions of barking deer habitat, and changes in suitable habitat across these periods. The model had excellent performance (AUC = 0.936, TSS = 0.823) and jackknife tests showed that precipitation seasonality (Bio15) contributed 32.2% to model predictions, temperature seasonality (Bio4) 28.5%, and annual mean temperature (Bio1) 27.0%. In the current period, highly suitable habitat for barking deer represented 3.7%, moderately suitable habitat 4.4%, less suitable habitat 6.8%, and unsuitable habitat 85.1% of the study area. The gain in suitable habitat was greatest (30.2%) under SSP2-4.5 during 2061-2080. The predicted loss in the suitable habitat of barking deer across all periods was (19.7-23.3%) while the greatest loss (23.3%) was under SSP1-2.6 during 2061-2080. Overall, climate change is projected to result in an overall net gain in suitable habitat for barking deer. Future conservation efforts for barking deer should target currently suitable habitat forecasted to remain suitable.

Design of an integral sliding mode controller for reducing CO2 emissions in the transport sector to control global warming.

Scientific reports, 15(1):29100.

Carbon dioxide (CO2) is the significant contributor to greenhouse gases and plays a crucial role in the greenhouse effect and climate change. The primary source of CO2 emissions is fossil fuel combustion, basically due to human activities and transportation activities. The objective of this research is to develop a dynamic model aimed at mitigating global warming by reducing atmospheric CO2 emissions resulting from the transportation sector. The model includes equations for atmospheric CO2 emissions, human population, vehicle population, and global warming. Initially, the stability of the model at each equilibrium point is determined by analyzing the eigenvalues of the Jacobian matrix. Subsequently, sensitivity analysis is performed to predict the impact of any parameter of a vehicle population and CO2 emissions causing global warming. The vehicle parameters are then optimized by applying an integral sliding mode controller (ISMC) to decrease CO2 emissions and minimize global warming. The ISMC method effectively reduces CO2 emissions and offers stability for human and vehicle populations, ultimately leading to a reduction in global warming. It is has been found that reducing the vehicle population by 20% can lead to about 4% reduction in CO2 emissions. This study integrates optimization control techniques to develop a comprehensive model to address CO2 emissions and global warming, providing a robust framework for sustainable environmental management.

Arsenic health risk in shallow groundwater of the alluvial plains in the lower Yellow River, China: driving mechanisms of climate change and human activities.

Environment international, 202:109711 pii:S0160-4120(25)00462-3 [Epub ahead of print].

Groundwater arsenic contamination poses a significant public health threat. The mechanisms driving high-arsenic concentrations in groundwater are highly intricate, and the interactions influencing the spatial distribution of arsenic remain insufficiently understood. In this study, we developed a robust machine learning model framework to predict the spatial variation of arsenic levels in shallow groundwater within the alluvial plains of the lower Yellow River. Additionally, we investigated the underlying factors that govern arsenic distribution in this region. The findings indicate that the improved high-arsenic probability map can accurately identify high-arsenic exposure areas. Compared with 2010, the distribution pattern of high-arsenic risk in the study area in 2020 has changed, with a decrease in risk in the north and an increase in concentrated risk in the south, and the potential population in the south exposed to health risks has increased to 2.02 million. Environmental factors such as temperature, clay-sand ratio, hydraulic gradient, precipitation, and water level change have a significant impact on arsenic release. Comprehensive analysis shows that hydrogeological conditions, human activities, and climate change work together to shape the distribution pattern of high-arsenic groundwater in the lower Yellow River. The synergistic effect of the climate factor group regulates high-arsenic to a greater extent than human activities and hydrogeological conditions. Especially under arid climate conditions, climate change and groundwater exploitation have a synergistic effect on arsenic release, controlling the distribution of high-arsenic by up to 55%. This study provides a scientific basis for predicting regional health risks, strengthening water resources management and pollution control.

Winter Climate Change Reshapes Soil Climate and Biogeochemistry in a Novel Snowmelt Experiment.

Global change biology, 31(8):e70405.

Winter climate change is outpacing our conceptual understanding of how winter conditions regulate soil biogeochemical cycling and ultimately impact vital ecosystem services like soil carbon and nutrient retention. In seasonally snow-covered ecosystems like northern temperate forests, increasingly inconsistent winters lead to less precipitation falling as snow, frequent midwinter snow melting, and the loss of a stable, insulative snowpack. These changes leave soils vulnerable to freezing, freeze/thaw cycling, and increasing dry/wet cycles from added snowmelt and rainwater. To uncover how these new winter soil climate conditions alter soil biogeochemistry, we introduce the DeFR❆ST (Determining Forest Responses to Snowmelt Treatments) experiment, a novel approach where we melt snow in situ throughout the winter and monitor changes to soil climate, gas exchange, and biogeochemical cycling. We installed DeFR❆ST in a New England temperate forest, an ecosystem that is part of the most significant global carbon sink and is also in the epicenter of winter climate change in the US. Experimental snow melting drove soil moisture fluctuations in addition to deep and persistent soil freezing. In turn, soils in melted plots exhibited blocked gas diffusion and lower soil oxygen availability. Oxygen limitation may have driven shifts in soil processes from high redox potential metabolisms like aerobic decomposition and nutrient mineralization towards low redox potential metabolisms like iron reduction and the dissolution of iron and carbon from organo-mineral associations. As these changes snowball, altered soil properties and shifts in soil microbial community structure and function could reshape forest biogeochemical cycling, both in these forests and more broadly across seasonally snow-covered ecosystems.

Predicting the impact of climate change on forest composition, deer, and outdoor recreation using structural equation modeling (SEM) in northeastern Minnesota.

Journal of environmental management, 392:126695.

Climate change will cause shifts in ecosystems and habitats by the end of the century, which will affect forested areas at the southern edge of the boreal biome such as the Laurentian Mixed Forest Province of northern Minnesota. We use a structural equation modeling (SEM) approach and climate projections for three future time periods, 2040-2059, 2060-2079, and 2080-2099 to generate predictions for forest composition, deer, and outdoor recreation, under climate change for the Laurentian Mixed Forest. We find that Minnesota's current boreal forest, dominated by aspen-birch and spruce-fir, will shift to a deciduous forest dominated by oak-hickory by 2100. With climate change and the change in forest composition, deer are predicted to have large increases. Most recreation categories are predicted to increase under climate change, driven largely by warmer temperatures, but cross-country skiing is predicted to suffer large declines. Our study provides predictions on outdoor recreation using a systems modeling framework with multiple interacting drivers (climate change, forest composition, deer populations), incorporating multiple types of variables (exogenous, endogenous, latent, compound), and models with and without a reciprocal interaction between forest composition and deer.

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.

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

Journal of environmental management, 392:126575.

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.

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.

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

Acta tropica, 269:107751.

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.

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

Canadian journal of anaesthesia = Journal canadien d'anesthesie, 72(8):1233-1239.

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.

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.

Impact of climate change and extreme temperature on the incidence of infectious disease among children and adolescents in China: A nationwide case-crossover study with over 8.7 million cases between 2008 and 2019.

The Journal of infection, 91(2):106547.

BACKGROUND: The relationship between ambient temperature and infectious disease incidence lacks comprehensive documentation. Our study, therefore, sought to systematically determine the national association between temperature and the incidence of infectious diseases, categorized into respiratory, gastrointestinal and enterovirus, and vector-borne categories. We aimed to study the association between extreme cold and heat extreme temperature on infectious disease occurrence among children and teenagers, and to evaluate the secular trends in these diseases in relation to temperature extremes.

METHODS: We accessed the dataset encompassing 8,731,930 cases of 27 distinct infectious diseases, spanning respiratory, gastrointestinal and enterovirus infections, and vector-borne categories, across 507 Chinese cities from 2008 to 2019. Employing a time-stratified case-crossover design, we quantified the association between temperature exposure and the risk of infectious diseases specific to each city. The attributable fractions for temperature-related risks were determined by identifying extreme temperatures exceeding the 90th percentile and falling below the 10th percentile of the respective city-specific temperature distributions, indicative of heat and cold effects. A comparative analysis of these attributable fractions between the periods 2008-2010 and 2017-2019 was conducted to evaluate the secular changes of infectious diseases associated with cold and heat.

FINDINGS: Our analysis revealed significant non-linear associations between temperature and the incidence of specific infectious diseases. Cold temperatures were found to be responsible for 1.35% (95% CI: 1.18 to 1.51%) of respiratory infectious disease cases. In contrast, heat was attributed to a lower proportion, with 0.29% (95% CI: 0.25 to 0.33%) of such cases. Among gastrointestinal and enterovirus diseases, a more substantial 4.93% (95% CI: 4.82 to 5.04%) of cases were linked to heat exposure. Notably, vector-borne diseases demonstrated the highest attributable fraction to heat, with 22.12% (95% CI: 21.82 to 22.41%) of cases affected. Specifically, five diseases-scarlet fever, tuberculosis, mumps, leprosy, and typhus-exhibited an increased incidence associated with cold temperatures. Notably, for scarlet fever, leprosy, and typhus, the attributable fraction escalated from the period 2008-2010 to 2017-2019. However, findings for leprosy should be interpreted with caution due to its low incidence. As for heat-related diseases, thirteen were identified, with the attributable fraction for nine diseases-tuberculosis, pertussis, hand, foot, and mouth disease, infectious diarrhea, dysentery, hepatitis A, typhoid and paratyphoid, dengue, and Japanese encephalitis-showing a marked increase over the same comparative timeframes.

INTERPRETATION: The temperature increase observed from 2008-2010 to 2017-2019 has been accompanied by a rising trend in heat-related infections. Among all infectious diseases in Chinese children and adolescents, more than half (13 out of 24) are heat-related, compared to five infections linked to extreme cold. The risk of gastrointestinal and enterovirus infections was associated with extreme hot temperatures, with vector-borne diseases particularly responsive to extreme heat. These findings highlight an urgent requirement for proactive public health measures to address the potential impact of temperature variability on infectious disease outbreaks, safeguarding vulnerable demographics in the context of climate change.

Global insights from a decade of nesting data for olive ridley, green, hawksbill, and leatherback turtles: Implications for conservation in the face of climate change.

Journal of thermal biology, 131:104196.

Sea turtles have existed on Earth for approximately 150 million years, during which time they have adapted to various environmental and oceanographic changes. However, the effects of current climate change on these reptiles are of concern due to the direct impact of temperature on sex ratio and hatching success. Low temperatures generally produce male offspring, while high temperatures favor the development of females, with an upper limit of thermal tolerance ranging between 33 and 35 °C. Global warming poses both a long-term risk of feminization of sea turtle populations and a short- and medium-term risk of decreased hatching success. The objective of this study was to evaluate the reproductive parameters of four species of sea turtles (Lepidochelys olivacea, Chelonia mydas, Dermochelys coriacea and Eretmochelys imbricata) during the last decade by carrying out a systematic review, in which 100 published articles were analyzed following the PRISMA methodology. The results revealed a significant bias towards female offspring in all species, with recorded values of up to 100 % (Lepidochelys olivacea) and 98 % (Chelonia mydas). When analyzing hatching success, it was observed that no species reaches 100 % success and that Chelonia mydas has the highest average (68.9 %), while Dermochelys coriacea records the lowest values (50.4 %). It important to note that reproductive parameters vary between species and populations. The undeniable tendency towards female offspring in all species is evident. However, this dynamic may result not only from recorded temperatures but also from the evolutionary history of sea turtles.

Optimal nitrogen fertilizer rates combined with alternating wet and dry irrigation effectively reduce greenhouse gas emissions in rice-wheat rotation system under climate change scenarios.

Journal of environmental management, 391:126472.

Water and nitrogen management practices have important effects on crop yields and greenhouse gas (GHG) emissions [including methane (CH4) and nitrous oxide (N2O)] in rice-wheat rotation system. However, research on the effects of water and nitrogen management practices on GHG emissions and crop yields (especially CH4 emissions) lacks consideration of climate change. In this study, we chose the Yangtze River Delta region (YRD) as the study area, and used the Denitrification-Decomposition (DNDC) model and 25 global change models (GCMs) to simulate the effects of different water and nitrogen management practices on crop yields and GHG emissions in the rice-wheat rotation system under climate change scenarios. Water and nitrogen management practices included (1) traditional nitrogen fertilizer rate (CK), (2) alternating wet and dry irrigation + traditional nitrogen fertilizer rate (AWD), (3) optimum nitrogen fertilizer rate (OF), and (4) the combination of AWD and OF (AWDOF). The climate change scenarios included three Shared Socio-economic Pathways scenarios (SSP-126, SSP-245, and SSP-585). We validated the DNDC model using crop yields data from statistical yearbooks and GHG emissions data from the published literature. The results indicated that DNDC simulation results were consistent with the measured values for the simulated crop yields (R[2]: 0.71-0.77), CH4 emissions (R[2]: 0.77-0.92) and N2O emissions (R[2]: 0.65-0.92), respectively. Moreover, climate change increased crop yields and GHG emissions in rice-wheat rotation system, with GHG emissions increasing significantly faster than crop yields. The AWD treatment decreased CH4 emissions but increased N2O emissions. The OF treatment decreased N2O emissions but was less effective in extreme climate scenarios (SSP-585-2080s). The AWDOF treatment was most effective in decreasing GHG emissions. In the AWDOF treatment, CH4 emissions and GWP decreased compared to historical period (1985-2016). AWDOF treatment was effective in the southeastern part of the YRD region due to the heterogeneity of climate change. Our study demonstrated the importance of water and nitrogen management practices to cope with future climate change in rice-wheat rotation systems, and they will be useful to policy makers in establishing smart agricultural systems.

Future climate change will drive expansion of suitable planting areas for Fructus Aurantii in Jiangxi Province, China.

Frontiers in plant science, 16:1579546.

Fructus Aurantii (FA) is a valuable medicinal material used in traditional China medicine. Predicting the suitable distribution areas of FA and identifying its potential distribution patterns driven by various environmental factors are crucial for the selection of planting sites and maintenance of medicinal quality. Here, the maximum entropy model was used to predict the potential distribution of FA in Jiangxi Province, China under current and future climate conditions. A total of 105 geographical distribution data of FA were collected through field investigation and 32 environmental variables were obtained from public databases. The maximum entropy model showed high prediction accuracy when 16 environmental variables were selected (AUC = 0.932). The habitat suitability of FA was prominently affected by climate, which surpassed topography and soil factors. Maximum temperature of the warmest month, annual temperature range, precipitation of the wettest month, precipitation coefficient of variation, elevation, aspect, and soil organic carbon were the key factors shaping the geographic distribution of FA. Among them, maximum temperature of the warmest month (16.9%), followed by annual temperature range (16.1%), made the greatest contribution to model predictions. In the current climate background, the total potential suitable area for FA covered 6.30 × 10[4] km[2] of garden land. Under future climate warming scenarios (shared socioeconomic pathways 245, 585), the potential suitable area was predicted to move southward and expand twice in 2040-2080, with notable increase in moderately and poorly suitable areas. Low hilly areas at higher elevations with moist cool conditions and gentle undulations would become more suitable for future introduction and planting of FA. Regionalized strategies for different suitable planting areas were proposed taking into account future climate change. All data are available in Mendeley Data (DOI: 10.17632/s9wsnn2xcn.1).
