It highlights how climate scientists experience feelings of despair, anxiety, sadness and worry, yet hesitate to communicate these emotions due to the prevailing norm that rigorous science should be objective, value-free and apolitical — essentially unemotional. This problematic dichotomy between emotion and science, particularly in the natural sciences, resonates deeply with our experiences as qualitative human geographers working on climate adaptation and climate justice.While Schipper et al. focus on the emotional burdens in climate science more broadly, we believe that one aspect warrants further attention: the profound emotional challenges that may arise specifically during and after ethnographic fieldwork. Unlike laboratory or desk-based work, ethnographic fieldwork — especially in regions disproportionately affected by climate change — often places researchers in direct contact with the environments and communities where the immediacy of climate impacts and human vulnerability is most acute and palpable. It may be one thing to model the rise of global temperatures or project the consequences of climate change in a controlled and stable environment; it is another to confront the tangible impacts of these changes in person on the ground. The embodied detachment provided by engaging with quantitative models and computer simulations that are abstracted and distant from the everyday human experience of climate change, as well as from individuals’ hopes, dreams and identities, may create psychological buffers that field scientists might lack. Fieldwork, by its nature, is a deeply embodied experience2.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"4 1","pages":""},"PeriodicalIF":30.7,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143775365","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, the governance implications of proposed upscaling of such interventions are uncertain. We conduct a survey of 332 intervention practitioners, revealing five types and 17 sub-types of interventions proposed or deployed in 37 marine systems globally. Most (71%) report marine-climate interventions aimed at supporting species and ecosystem adaptation, with 29% aimed primarily at climate mitigation and societal adaptation. Perceptions of climate benefits vary widely, with low consensus across practitioners on the climate goals of specific interventions. Intervention decision-making also remains focused on technical feasibility to meet minimum permitting requirements, with limited appraisal and management of broader ecological, cultural and social risks and benefits of intervention. Practitioners also warn that many marine-climate interventions are currently being tested and deployed in an under-regulated pseudo-scientific bubble. Oceans are on the front line of new planned climate actions, but understanding of novel marine-climate intervention development and deployment remains low. Here a survey among intervention practitioners allows identification of science and governance gaps for marine-climate interventions.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"15 4","pages":"375-384"},"PeriodicalIF":29.6,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41558-025-02291-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766349","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, using a LUC dataset incorporating remote-sensing and national forest inventory data with two modelling approaches, we show that ELUC in China shifted from a carbon source to a sink in the 1990s, contributing to a net cumulative CO2 removal of 2.0 Pg C during 1981–2020. From 2001 to 2020, the average ELUC was −0.14 Pg C yr−1, accounting for over one-third of the national land carbon sinks. Forest-related LUC activities contributed greatly to national carbon fluxes, while non-forest-related activities played a dominant role in certain areas. Our findings suggest that the carbon sinks from LUC activities in China may be largely underestimated in global assessments, underscoring the need to develop region-specific modelling for evaluation and potential regulation. The terrestrial carbon flux—sources and sinks—under land-use change (LUC) is difficult to quantify. Here, using a LUC dataset drawing on remote sensing and forest inventory data, the authors show that in China the carbon sink from LUC (such as afforestation) may be underestimated.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"15 4","pages":"428-435"},"PeriodicalIF":29.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744732","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}

By combining ground-based datasets and ESMs, we find that this paradoxical phenomenon is predominantly driven by an overestimation of light snowfall frequency. Using spatially distributed emergent constraints, we show that this paradox persists in mid- (2041–2060) and long-term (2081–2100) projections, affecting more than half of the Northern Hemisphere’s land surface. ESMs underestimate the frequency of freezing days by 12–19% and overestimate snow water equivalent by 28–34%. Constrained projections indicate that the raw ESM outputs overestimate future Northern Hemisphere snowmelt water by 12–16% across 53–60% of the Northern Hemisphere’s land surface. This snowmelt water overprediction implies that the amount of water available in the future for agriculture, industry, ecosystems and domestic use may be lower than unadjusted ESM projections suggest.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"33 1","pages":""},"PeriodicalIF":30.7,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143723125","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}

Here, using spatial analysis and financial valuation of the BCP service, we estimate that, annually, the BCP adds 2.81 GtC (range 2.44–3.53 GtC) to the ocean with a storage time of at least 50 years (±25 years). This ecosystem service is worth US$545 billion per year (US$471–694 billion) in areas beyond national jurisdiction and US$383 billion per year (US$336–471 billion) within all exclusive economic zones, where the sum of its discounted values for 2023–2030 is US$2.2 trillion (range US$1.9–2.7 trillion). These results quantify the climate and economic importance of the BCP and the important role of large ocean states in carbon sequestration. These findings can support discussions in climate finance and in the COP global stocktake for climate action. This study quantifies and values the carbon stored in the ocean due to biological processes. With uptake in the order of 2.8 Gt per year, valued at around US$1 trillion annually (at a carbon price of US$90 per ton of CO2), this service should be included in the global stocktake and climate actions.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"15 4","pages":"385-392"},"PeriodicalIF":29.6,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143712789","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}
