Here we find that overall trade risks decrease in most countries (70%) in net-zero scenarios due to reduced reliance on imported fossil fuels, but trade risks to either electricity or transportation systems increase in the majority (82%) of countries that become more dependent on imported materials. Countries with abundant mineral reserves (for example, Australia and China) become much less dependent on imports, but the opposite is true of countries with large fossil fuel reserves (for example, Russia and the Middle East). We further evaluate the sensitivity of countries’ trade risks to differences in trading networks, energy systems, the material intensities of technologies and recycling rates, highlighting opportunities for technological innovation and policy changes.</p>","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"38 1","pages":""},"PeriodicalIF":30.7,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143805827","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}

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.</p><p>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 experience<sup>2</sup>.</p>","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}
