However, knowledge gaps exist in quantifying the attributable burden. Here we assessed the burden of MBDs attributable to temperatures above the location-specific thresholds from 2003 to 2018 using disability-adjusted life years and projected future burdens under the climate scenarios representative concentration pathways RCP 4.5 and 8.5 across Australia, considering various climatic, demographic and adaptation scenarios. We show that high temperatures contributed to an annual loss of 8,458 disability-adjusted life years, representing 1.8% of total MBD burden in Australia. Our findings project a consistent upward trend in the high-temperature-attributable burden of MBDs over time. Specifically, this burden is expected to increase by 11.0–17.2% in the 2030s and by 27.5–48.9% in the 2050s compared to the baseline.

Although surface heatwaves are well studied, their vertical structures within lakes remain largely unexplored. Here we analyse the characteristics of subsurface lake heatwaves (extreme hot events occurring below the surface) using a spatiotemporal modelling framework. Our findings reveal that subsurface heatwaves are frequent, often longer lasting but less intense than surface events. Deep-water heatwaves (bottom heatwaves) have increased in frequency (7.2 days decade<sup>−1</sup>), duration (2.1 days decade<sup>−1</sup>) and intensity (0.2 °C days decade<sup>−1</sup>) over the past 40 years. Moreover, vertically compounding heatwaves, where extreme heat occurs simultaneously at the surface and bottom, have risen by 3.3 days decade<sup>−1</sup>. By the end of the century, changes in heatwave patterns, particularly under high emissions, are projected to intensify. These findings highlight the need for subsurface monitoring to fully understand and predict the ecological impacts of lake heatwaves.</p>","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"12 1","pages":""},"PeriodicalIF":30.7,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143813634","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}
