ER responds positively to increasing temperature, so a warming world is hypothesized to lead to additional CO<sub>2</sub> release, potentially further exacerbating climate warming. The long-term influence of thermal changes on this carbon–climate feedback, however, remains unresolved. Here, by compiling data from 221 eddy covariance sites worldwide, we observe decreases in the temperature sensitivity and reference respiration rates of ER with increasing mean annual temperature, suggesting that ER adapts to temperature changes. Our results further reveal that thermal adaptation would eliminate 17.91–31.41% of the anticipated increase in the respiration of unadapted ecosystems under future warming scenarios, equivalent to a net carbon loss of 0.85–11.83 Pg C per year. The increase in respiration rates of terrestrial ecosystems in response to climate warming may thus be lower than predicted, with important consequences for modulating future terrestrial carbon–climate feedback.</p>","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"277 1","pages":""},"PeriodicalIF":30.7,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144652247","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}

Satellite-era warming trends in four commonly used global (land and ocean) temperature reconstructions agree closely, yet whether SST datasets also agree is unclear. Here we show that trends in four widely used SST datasets show first-order differences, with 1982–2024 60° S to 60° N trends ranging from 0.108 to 0.184 °C per decade. These large discrepancies are perplexing given the agreement between global temperature datasets and the fact that 70% of the surface of the Earth is covered by ocean, but are legible upon recognizing that global temperature datasets use two SST fields whose trends agree more closely than those of the four SST datasets. Considering the trend uncertainty across SST datasets widens the range of plausible global temperature trends and impacts interpretations of recent record global temperatures, with implications for observational and model-based climate studies.</p>","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"4 1","pages":""},"PeriodicalIF":30.7,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144603568","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}

The Arctic and subarctic regions are experiencing exceptionally rapid warming, known as Arctic amplification, yet its impact on oceanic oxygen remains poorly understood. Here we show that inflowing Atlantic Water (AW) drives deoxygenation in the upper eastern Arctic Ocean and the intermediate layers of the western Arctic Ocean at rates from −0.41 ± 0.17 to −0.47 ± 0.07 µmol kg<sup>−1</sup> yr<sup>−1</sup>, six times the global mean. Amplified Arctic warming is the primary driver, significantly reducing oxygen solubility in the Arctic gateway regions. Rapid subduction and circulation of AW further transmit the deoxygenation signal into Arctic deeper layers, greatly threatening marine ecosystems. Our findings highlight the dominant role of warming Atlantic inflow in shaping the Arctic Ocean oxygen dynamics, indicating that ongoing temperature increases will perpetuate deoxygenation trends and underscoring the need for widespread attention.</p>","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"21 1","pages":""},"PeriodicalIF":30.7,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144586653","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}

However, our understanding of Antarctic surface meltwater is limited, with previous studies restricted in spatial or temporal scope.

Surface meltwater covered 3,732 km<sup>2</sup> across Antarctica on average during each melt season, with 30% on grounded ice. High interannual variability in meltwater area across the Antarctic Peninsula and in East Antarctica correlates with large-scale modes of climate variability. In west Antarctica, meltwater area is comparatively low and this correlation is absent. An increase in the magnitude and variability of surface meltwater area without a coincident increase in modelled snowmelt in East Antarctica indicates that the ice-sheet surface might be becoming more favourable to meltwater ponding.</p>","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"48 1","pages":""},"PeriodicalIF":30.7,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144565932","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}
