Less persistent bioplastic alternatives are available but also have unknown environmental effects. We conducted a three-month experiment exposing plankton in experimental ponds to 10 concentrations of three different thermoplastic polyurethane microplastics, including two biodegradable bioplastics. Algal blooms with dense chlorophyll occurred consistently at high concentrations of the petroleum-derived thermoplastic polyurethane, but only occasionally with the two bioplastics. Herbivorous zooplankton density was strongly reduced by typical thermoplastic polyurethane and only weakly by bioplastics, therefore the effect on algae is at least partly due to reductions in top-down grazing pressure. Microbial communities exhibited compositional shifts in response to all three plastic types, with petroleum-derived plastic associated with the most pronounced differences across both prokaryotic and eukaryotic domains. Our results show that plastic pollution may contribute to the growing global problems of eutrophication, coastal hypoxia and harmful algae blooms, and that biodegradable plastics may have smaller environmental footprints.","PeriodicalId":521223,"journal":{"name":"Communications sustainability","volume":"1 1","pages":"16"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12863645/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146115520","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}

A key component of the water balance is evapotranspiration, the combination of soil and surface evaporation and plant transpiration. Evapotranspiration is influenced by natural drivers (e.g., climate, vegetation cover) and human intervention (e.g., irrigation, land management). Here, we analyze the transition between one of California's driest years (2022) to an exceptionally wet year (2023) to assess evapotranspiration responses to climate extremes. Despite increased precipitation, total statewide evapotranspiration changed less than 10%. In 2022, human contributions accounted for 30% of statewide evapotranspiration and 80% in managed lands. In 2023, natural evapotranspiration increased, and human contributions fell by 30%, yet still comprised nearly 50% of evapotranspiration in managed areas. Our findings underscore the enduring role of human activity on California's hydrology, even during wet years, and demonstrate a framework to separate natural and anthropogenic controls on evapotranspiration.","PeriodicalId":521223,"journal":{"name":"Communications sustainability","volume":"1 1","pages":"8"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12863644/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146115511","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}

We take a closer look at these voices by examining Congressional speeches from 1994 to 2023, a period containing important moments in the history of climate (in)action in the US. We contribute to the literature by 1) developing a scalable large language model (LLM) to accurately classify climate contrarianism in Congressional speech and 2) offering a systematic analysis of the specific contrarian claims in Congress. We demonstrate that an increasing proportion of speeches are critiquing the costs of climate solutions and Republicans are roughly 12 times more likely than Democrats to make contrarian claims. Statistical analysis further suggests that demographic factors and district-level fossil fuel employment predict claims making in floor speeches.","PeriodicalId":521223,"journal":{"name":"Communications sustainability","volume":"1 1","pages":"37"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12983461/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147464718","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}

As electrolyzer plants scale up, cooling can become a hidden water demand, especially in hot and water-stressed regions where many renewable hydrogen projects are planned. Here we combine a thermodynamic cooling model with climate reanalysis, global water-stress data and renewable capacity-factor maps to quantify evaporative-cooling water demand for electrolysis across regions and seasons. We show that cooling can dominate total water use and that high solar-resource regions frequently coincide with high water stress and high cooling demand. Wind-rich regions, in contrast, are more often located in cooler or more water-abundant settings. A composite Water Risk Index identifies where freshwater-based evaporative cooling is likely to require alternatives such as dry or hybrid cooling, desalination or reclaimed-water supply. Our results show that cooling technology and water sourcing are central to water-sustainable hydrogen planning.","PeriodicalId":521223,"journal":{"name":"Communications sustainability","volume":"1 1","pages":"103"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13303071/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148348796","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}

Here we report an analysis of continuous in-river monitoring over 16 months, using a custom-made physical-interception litter trap in the Rhine River, one of Europe's largest rivers. In collaboration with citizen scientists, we collected 20,339 floating macrolitter items larger than 1 cm that we classified according to international standards. We find that private consumers are the largest source of macrolitter at 56.4%. Plastics comprised 69.7% of macrolitter by particle number but only 14.8% by weight, underscoring the relevance of non-plastic materials. Based on our data, we estimate the annual macrolitter transport towards the North Sea to amount to 27 to 42.2 million items, or 3,010.5 to 4,707.5 t in the Rhine River, which significantly exceeds previous estimates. Macrolitter abundance fluctuated by a factor of 41 between biweekly samples and was higher at times of rising discharge. As such, we suggest that long-term monitoring is essential, and river discharge forecasts could serve as a predictor to guide clean-up efforts.","PeriodicalId":521223,"journal":{"name":"Communications sustainability","volume":"1 1","pages":"5"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12863643/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146115518","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}

Yet, few studies directly compare politicians' climate beliefs with those of citizens. Here, we used a large cross-national sample of politicians (N = 714) and citizens (N = 18,281) to explore how political orientation predicts climate beliefs and policy support in Australia, Belgium (Flanders and Wallonia), the Czech Republic, Germany, Israel, Luxembourg, the Netherlands, and Norway. Our results show that right-leaning politicians and citizens express weaker beliefs in anthropogenic climate change than left-leaning individuals. Ideological polarization is substantially stronger among politicians. Notably, right-leaning politicians are even less convinced about climate change than their own voters. These ideological divides are reflected in policy preferences: in both groups, belief in anthropogenic climate change statistically mediates the association between political orientation and support for mitigation policies, with markedly stronger mediation among politicians. Together, the results suggest that ideological gaps in climate beliefs, especially among politicians, may contribute to polarization in support for mitigation measures.","PeriodicalId":521223,"journal":{"name":"Communications sustainability","volume":"1 1","pages":"111"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13368580/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148458380","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}
