Identifying correlated responses to warming tolerance evolution could identify such negative consequences and help uncover the underlying mechanisms. By assessing the correlated responses of life history and physiological traits to seven generations of artificial selection to increase or decrease the acute upper thermal tolerance limit (CTmax) in zebrafish (Danio rerio), we show that warming-adapted lines have improved cooling tolerance. Furthermore, the absence of difference between selected lines in aerobic metabolic scope, brain heat shock protein levels, fecundity, growth or swimming speed contradicts several hypotheses concerning the mechanisms controlling acute warming tolerance. These results suggest that selection due to acute heating events does not target variation in metabolic rates but can benefit tolerance to cold, making individuals more resilient to extreme temperature events.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"116 1","pages":""},"PeriodicalIF":30.7,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143945686","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}

Kopp and colleagues1 raise important questions about the conceptual clarity and practical utility of tipping points research. While we welcome these questions and share their commitment to precise language and careful scientific communication, we worry that the negative orientation of their paper may lead some scholars to discard tipping points research before fully appreciating its value. We therefore highlight more positive conceptual and empirical insights relating to four topics raised by Kopp and colleagues.First, tipping points theory has developed scientifically rigorous foundations since first being applied to climate science in 2008. Essential features — including system reorganization, thresholds, self-propelling feedbacks and nonlinear change — are now well established in the scientific literature2. Like other complex concepts in sustainability science, the term’s use can diversify across various disciplines, and it can be misunderstood and misrepresented. This presents opportunities to study and improve how tipping points science is communicated, rather than grounds for dismissal. The concept has also been usefully applied across diverse disciplines and topics — including the acceleration of species’ extinction, groundwater resource depletion, the rise of asset uninsurability and the growing amount of space debris3. This ability of the tipping points approach to be tailored to suit different research topics can be viewed positively and can contribute to a broader and richer understanding of the concept.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"31 1","pages":""},"PeriodicalIF":30.7,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143940296","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, little is known about how responsibility is perceived across low- and middle-income countries, particularly in Africa. Without clear attribution of responsibility, growing climate vulnerability and risk cannot be effectively or equitably addressed.Nicholas Simpson from the University of Cape Town and colleagues from South Africa, the USA and the UK analysed public opinion data from 39 African countries. They find that citizens who are aware of climate change primarily assign responsibility for addressing climate change to their own governments, followed by ordinary African citizens, and then to a mix of industry and historic emitters. But these notions of responsibility are not uniform, and variation is associated with sociodemographic factors and state capacity. Higher education levels, reduced poverty and access to new media sources are associated with increased attribution of responsibility to historical emitters. This study highlights that many Africans are willing to act on the climate crisis and expect their governments to do the same.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"35 1","pages":""},"PeriodicalIF":30.7,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143930789","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}
