Here we use fossil Porites coral records of skeletal growth and environmental variability from the subtropical Central Paratethys Sea to assess coral resilience to past ocean warming and acidification. These records offer a unique perspective on the calcification performance and environmental tolerances of a major present-day reef builder during the globally warm mid-Miocene CO2 maximum and subsequent climate transition (16 to 13 Ma). We found evidence for up-regulation of the pH and saturation state of the corals' calcifying fluid as a mechanism underlying past resilience. However, this physiological control on the internal carbonate chemistry was insufficient to counteract the sub-optimal environment, resulting in an extremely low calcification rate that likely affected reef framework accretion. Our findings emphasize the influence of latitudinal seasonality on the sensitivity of coral calcification to climate change.","PeriodicalId":10530,"journal":{"name":"Communications Earth & Environment","volume":"6 1","pages":"569"},"PeriodicalIF":8.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12274133/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144674033","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}

Understanding the effects of permafrost thaw is vital for informed policymaking and adaptation efforts. Here, we present the consolidated findings of a risk analysis spanning four study regions: Longyearbyen (Svalbard, Norway), the Avannaata municipality (Greenland), the Beaufort Sea region and the Mackenzie River Delta (Canada) and the Bulunskiy District of the Sakha Republic (Russia). Local stakeholders' and scientists' perceptions shaped our understanding of the risks as dynamic, socionatural phenomena involving physical processes, key hazards, and societal consequences. Through an inter- and transdisciplinary risk analysis based on multidirectional knowledge exchanges and thematic network analysis, we identified five key hazards of permafrost thaw. These include infrastructure failure, disruption of mobility and supplies, decreased water quality, challenges for food security, and exposure to diseases and contaminants. The study's novelty resides in the comparative approach spanning different disciplines, environmental and societal contexts, and the transdisciplinary synthesis considering various risk perceptions.","PeriodicalId":10530,"journal":{"name":"Communications Earth & Environment","volume":"6 1","pages":"21"},"PeriodicalIF":8.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11738985/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143001476","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}

Here we explore perceptions using small group deliberation (n60) plus a nationally representative survey (n2027) in the UK's four jurisdictions. We find a strong preference for carbon removal to play a substantial role in meeting national climate targets, stemming from persistent scepticism about emissions reductions and behaviour change. However, such support was tempered with caution about whether certain biological techniques - biochar, peatland restoration, and perennial biomass crops - would be \"worth it\". In particular, concerns were raised about life-cycle emissions, as well as land competition with urgent housing needs, and scientific uncertainty around novel techniques such as biochar. While we find that responses to carbon removal tend to shift the burden of responsibility for climate action away from individuals, we also identify region-specific discourses, highlighting the importance of local context in shaping public views.","PeriodicalId":10530,"journal":{"name":"Communications Earth & Environment","volume":"6 1","pages":"711"},"PeriodicalIF":8.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12394068/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144945612","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}

Here we explore a potentially more efficient alternative: weakening the Earth's greenhouse effect by deploying absorptive aerosols in the upper stratosphere (~10 hPa). These aerosols warm the carbon dioxide emission level-where outgoing longwave radiation is most sensitive to temperature-thereby enhancing top-of-atmosphere infrared emission without altering atmospheric carbon dioxide concentrations. Idealized climate model simulations indicate that this approach can reduce global temperatures an order of magnitude more efficiently per unit aerosol mass than conventional scattering-based interventions. Although based on simplified model experiments lacking interactive aerosol processes and operational constraints, our results identify a distinct physical mechanism for climate intervention, arguing for further research into the impacts-especially potential unintended side effects-of injecting absorptive aerosols into the upper stratosphere as an alternative solar radiation management strategy.","PeriodicalId":10530,"journal":{"name":"Communications Earth & Environment","volume":"6 1","pages":"485"},"PeriodicalIF":8.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12181077/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144368706","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, there remains a lack of understanding of snow processes and quantification of the contribution of melt to runoff. Here we apply a distributed glacio-hydrological model over the Rio Santa basin to disentangle the role of the cryosphere in the Andean water cycle. Only at the highest elevations (>5000 m a.s.l.) is the snow cover continuous; at lower elevations, the snowpack is thin and ephemeral, with rapid cycles of snowfall and melt. Due to the large catchment area affected by ephemeral snow, its contribution to catchment inputs is substantial (23% and 38% in the wet and dry season, respectively). Ice melt is crucial in the mid-dry season (up to 44% of inputs). Our results improve estimates of water fluxes and call for further process-based modelling across the Andes.","PeriodicalId":10530,"journal":{"name":"Communications Earth & Environment","volume":"6 1","pages":"434"},"PeriodicalIF":8.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12141031/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144246820","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}

To address this knowledge gap, we investigated foliar methane and nitrous oxide fluxes in Salix bebbiana, under varying light conditions (0-2000 μmol·m-2·s-1), soil aeration, and nitrogen availability, manipulated via biochar incorporation and nitrogen additions. Using rapid spectroscopic gas analysers, we observed consistent net foliar methane oxidation and nitrous oxide emission across all light conditions, demonstrating saturating light response patterns. Maximum flux rates were significantly more sensitive to soil conditions than carbon dioxide or water vapour exchange. Analysis revealed foliar methane and nitrous oxide fluxes overwhelmingly regulated by internal leaf processes like xylem transport, with modulation by external light intensity. These predictable light-response patterns provide a basis for scaling leaf-level methane and nitrous oxide fluxes, enhancing accuracy in predicting biogenic greenhouse gas fluxes within ecosystem and biosphere models.","PeriodicalId":10530,"journal":{"name":"Communications Earth & Environment","volume":"6 1","pages":"493"},"PeriodicalIF":8.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12182443/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144474149","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}
