However, the pattern and mechanisms governing the global interconnection of peak river discharge across spatially distant and proximate locations remain largely unexplored. Here, on the basis of a global annual peak discharge database from 4,407 observational hydrometric stations, we identify hubs for remotely linked discharge peaks spanning thousands of kilometres. We show increasing trends in the number of remotely linked watersheds and the total drainage area, pointing to amplified synchronization of global peak river discharge since the 1980s. Ocean–atmosphere oscillations, through the perturbation of both temperature and precipitation anomalies, dictate the global coupling pattern and temporal evolution of discharge peaks. Our findings highlight an emergent profile of global peak river flow in a warming climate that can benefit coordinated flood risk management. River floods that occur simultaneously in multiple locations can lead to higher damages than individual events. Here, the authors show that the likelihood of concurrent high river discharge has increased over the last decades.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"15 10","pages":"1084-1090"},"PeriodicalIF":27.1,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230908","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}

In the electric power sector, where utility infrastructure has ignited some of the most destructive fires, companies are investing heavily to reduce risk. Here we evaluate the costs, reliability implications and risk-reduction benefits of the largest utility wildfire mitigation programme in the United States. Using weather and vegetation data for 25,000 miles of high-risk power lines, we develop a predictive model of ignition risk and compare outcomes across locations that had similar risk profiles but received different interventions. A newer strategy—adjusting protective device sensitivity during high-risk conditions—has reduced more wildfire risk at lower cost per avoided structure burned than conventional approaches such as undergrounding or vegetation management. Our results underscore the importance of comprehensive accounting of costs, risks and reliability when evaluating adaptation investments, particularly where capital-intensive measures may be over-incentivized. Extreme events are increasingly becoming severe risks to the electric grid, yet there is limited understanding of the cost-effectiveness of adaptation investments. This research demonstrates that dynamic grid management could reduce large capital spending and limit wildfire risks in the USA.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"15 10","pages":"1115-1122"},"PeriodicalIF":27.1,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230904","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}

Despite recent advances, global and regional assessments are constrained by omitting critical factors such as land-use change, failing to disaggregate potential impacts by land uses and oversimplifying land subsidence. Here we address these gaps by developing context-specific scenarios to 2100 based on a comprehensive analysis of Chinese coastal development policies. We integrate high-resolution simulations of population and land-system changes with inundation exposure assessments that incorporate SLR, land subsidence, tides and storm surges, offering a more nuanced understanding of coastal risks. Across our plausible set of downscaled scenarios of shared socioeconomic and representative concentration pathways, policy decisions have a bigger effect on what is exposed to coastal flooding until 2100 than does the magnitude of SLR. Hence, coastal policy decisions largely influence coastal risk and adaptation needs to 2100, demonstrating the necessity of appropriate policy design to manage coastal risks. Coastal risk assessment under future climate change is important for effective adaptation, but multidimensional analyses are still rare. Here the researchers find that inappropriate development policies could have a greater effect on exposure to flooding than sea-level rise up to 2100 in China.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"15 10","pages":"1071-1077"},"PeriodicalIF":27.1,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41558-025-02439-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230905","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 long-term satellite data, we show that from 1982 to 2018, the burned area in the Arctic has significantly increased, while the duration of snow cover has significantly decreased. An XGBoost machine learning model and causal analysis confirmed the role of wildland fires in delaying snow cover formation, with this effect strongly linked to fire-induced reductions in albedo and increases in temperature. In addition, we observed a delay of more than 5 days in snow cover formation following major wildland fires. Looking ahead, our projections under a high-emissions scenario (Shared Socioeconomic Pathway, SSP 5-8.5) indicate that the burned area could increase by a factor of 2.6 and the annual mean snow cover duration could decrease by nearly 18 days between 2015 and 2100 compared with the historical average. Wildland fires are becoming more frequent in high-latitude regions. Here the authors show that these fires delay the formation of snow cover in the Arctic, which will be exacerbated under future warming due to increases in burned areas.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"15 10","pages":"1091-1098"},"PeriodicalIF":27.1,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41558-025-02443-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230918","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}
