Here we mapped the areas of 1,686 glacier lakes, just before they drained, across 13 glaciated mountain regions outside polar regions and examined the trends in pre-GLOF lake areas between 1990 and 2023. We found that pre-GLOF lake areas barely changed, or even decreased, regionally through time, even as the total lake area, and thus hazard potential, grew overall. This counterintuitive finding reflects limits to growing GLOF magnitudes, such as the decoupling of lakes and parent glaciers, the development of wide, low-gradient outlets or human management. Across all regions, pre-GLOF lake areas depend on a few ice-dammed lakes, which have produced ten times more reported outbursts and ten times larger outbursts than moraine- and bedrock-dammed lakes. The latter two dam types will continue to impound growing amounts of meltwater, thereby accounting for most of the overall GLOF hazard potential, while ice-dammed lakes will shrink with deglaciation. As these lake types will evolve differently in the twenty-first century, we call for customized simulations of GLOF outflows and impacts, given the growing exposure of critical infrastructure. By quantifying changes in lake area before glacier lake outburst floods (GLOFs) worldwide from 1990 to 2023, this study shows that despite the overall growth in total lake area and hazard potential, pre-GLOF lake areas barely changed or even decreased regionally and are dependent on a decreasing number of ice-dammed lakes.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 3","pages":"271-283"},"PeriodicalIF":0.0,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44221-025-00388-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Achieving precise water/ions separation while maintaining high water flux requires a membrane microstructure engineered with molecular precision. This study reports the successful synthesis of ultra-thin, centimetre-scale graphdiyne (GDY) films with ordered one-dimensional (1D) channels using single-crystalline Cu (111) as the growth substrate and demonstrates their exceptional performance as molecular sieves for highly efficient water/ion separation. The optimized membrane exhibits an ultra-high water/NaCl selectivity of 5.96 × 104, outperforming state-of-the-art membranes, at a water permeance of ∼32.9 mol m−2 h−1 bar−1 and a salt rejection exceeding 99.7% for small ions in seawater. Mechanism studies reveal that the hydrophobic angstrom-scale channels in GDY crystals force water molecules into a single-file configuration with 1D hydrogen bond during water permeation. The 1D water chain enables the GDY membrane to facilitate rapid (diffusion constant as high as 1.3 × 10−4 cm2 s−1) and selective proton transport via the Grotthuss mechanism. This work contributes to the development of carbon nanomaterial membranes for precise molecular sieving and biomimetic protonophores. Graphdiyne membranes with an extended two-dimensional network structure and ordered one-dimensional channels achieve an ultra-high water/NaCl selectivity and superior salt rejection.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 3","pages":"307-318"},"PeriodicalIF":0.0,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
