Here, using weekly water temperature data (1976–2099), we assess the vulnerability of 9,809 freshwater species to short- and long-term thermal extremes and show that gradual warming can trigger abrupt thermal exposure. Tropical regions experience a high proportion of species at risk, whereas non-tropical regions face severe thermal extremes. We introduce the concept of thermal fragmentation exposure to understand how heterogeneous warming fragments freshwater habitat, thereby amplifying local extinction risks. Around 63% of riverine fish will experience more persistent thermal barriers under a high-emissions scenario, with thermal fragmentation accelerating over time. These findings underscore the urgent need for targeted conservation strategies to safeguard freshwater fish biodiversity. Assessing 9,809 freshwater fish species globally, this study shows risk to a high proportion of species in the tropics, and severe extremes in non-tropical regions. Under high emissions, gradual warming drives abrupt exposure, with 63% of species facing accelerating thermal fragmentation by 2099.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"16 9","pages":"1061-1067"},"PeriodicalIF":26.9,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41558-026-02731-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing on a global database of tree-ring isotopes, eddy-covariance fluxes and satellite-derived vegetation metrics, here we show that PM2.5 exerts a predominantly negative influence on WUE across spatial scales. The magnitude of this effect varies geographically and is modulated by interactions among vegetation traits, pollution levels and climate, with forests and non-forests exhibiting distinct patterns. The WUE decline arises primarily from the PM2.5-induced suppression of photosynthesis rather than changes in evapotranspiration, due to reduced photosynthetically active radiation and carboxylation capacity. Current ecosystem models that omit aerosol processes fail to reproduce the observed PM2.5–WUE relation, which indicates that covarying climate drivers alone are insufficient to explain this effect. Our findings identify PM2.5 as an overlooked yet critical factor that weakens plant carbon–water coupling under climate change. The influence of fine particulate pollution (PM2.5) on plant water-use efficiency remains poorly understood. The authors highlight that PM2.5 exerts a primarily negative effect across scales due to asymmetric effects on photosynthesis and evapotranspiration.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"16 9","pages":"1068-1074"},"PeriodicalIF":26.9,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148769151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We develop the residual emissions strategy robustness index to assess the robustness of compensation strategies, indicating that the current maturity is medium-low with notable geographical disparities. Although cities invest in options mapping and governance, little attention is paid to land availability, the potential of the urban fabric to become a distributed carbon sink, provisions against carbon reversals, monitoring, timing and quantification (estimates cover only 18% of total residual emissions). We also distil recommendations and best practices to address residual emissions. Although many cities have set net-zero targets, there is limited understanding of their residual emissions strategies. An analysis of 103 European cities reveals best practices but also a potential over-reliance on temporary land-based carbon removal and the limited robustness of compensation strategies.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"16 9","pages":"1092-1101"},"PeriodicalIF":26.9,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41558-026-02691-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148729007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, such a threshold may not be meaningful because AMOC stability depends on the rate of radiative forcing change, not a set temperature. Here we identify an AMOC stabilizing mechanism that operates on timescales slower than present-day warming rates. Slow forcing permits coherent adjustment of surface and interior ocean properties, supported by enhanced evaporation and reduced sea-ice extent, counteracting destabilizing feedbacks. Using a slow CO2 ramp (+0.5 ppm yr−1) climate model simulation, we explicitly demonstrate the AMOC remains stable up to +5.5 °C of global warming. By contrast, under faster CO2 ramps, the AMOC collapses at substantially lower warming levels (+2 °C). Our findings demonstrate rate-induced AMOC tipping and imply that limiting the rate of emissions is critical for reducing the risk of an AMOC collapse. Climate change is expected to alter oceanic circulation, with the Atlantic Meridional Overturning Circulation (AMOC) at risk of collapse. This work shows that the stability of the AMOC is dependent on the rate of atmospheric CO2 change rather than having a fixed threshold.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"16 10","pages":"1195-1206"},"PeriodicalIF":26.9,"publicationDate":"2026-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41558-026-02730-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148729011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
