This requires understanding which behaviours, firms and industries have the greatest impact on emissions. Here we ask if people are knowledgeable enough to make choices that align with growing sustainability intentions. Across five studies, we (1) demonstrate that accuracy of individuals’ emissions-related estimates is limited, (2) provide evidence that this misestimation is consistent with a cognitive process of attribute substitution and (3) identify conditions that do (and do not) moderate estimation accuracy. Our findings suggest that individuals’ efficacy as consumers, investors and citizens is currently hampered by their misjudgements of carbon impact. We advocate accessible and easily understandable information that highlights the causal impact of consumption decisions to facilitate climate action. Individual actions are important to reduce emissions, yet consumers’ carbon incompetence may lead to ineffective efforts. This study demonstrates the consistent inaccuracy in assessing emissions of behaviours, firms and industries, which may be driven by lack of information or expertise.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":null,"pages":null},"PeriodicalIF":29.6,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141436163","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 rural households lacking access to running water, women often bear the responsibility for its collection, with adverse effects on their well being through long daily time commitments, physical strain and mental distress. Here we show that rising temperatures will exacerbate this water collection burden globally. Using fixed-effects regression, we analyse the effect of climate conditions on self-reported water collection times for 347 subnational regions across four continents from 1990 to 2019. Historically, a 1 °C temperature rise increased daily water collection times by 4 minutes. Reduced precipitation historically increased water collection time, most strongly where precipitation levels were low or fewer women employed. Accordingly, due to warming by 2050, daily water collection times for women without household access could increase by 30% globally and up to 100% regionally, under a high-emissions scenario. This underscores a gendered dimension of climate impacts, which undermines womens’ welfare. Water scarcity is becoming increasingly severe under climate change, and women often bear most of the burden of collecting water. This research finds that both temperature rises and reduced precipitation increase women’s daily water collection time, thereby undermining their welfare globally.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":null,"pages":null},"PeriodicalIF":29.6,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41558-024-02037-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141436196","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}

While variation in ST has been shown to be influenced by local climate adaptations, the impact of biodiversity remains unknown. Here we combine 393,139 forest inventory plots with satellite-derived ST across the northern hemisphere during 2001–2022 to show that biodiversity greatly affects spatial variation in ST and even surpasses the importance of climate variables. High tree diversity significantly weakened ST, possibly driven by changes in root depth and soil processes. We show that current Earth system models fail to reproduce the observed negative correlation between ST and biodiversity, with important implications for phenological responses under future pathways. Our results highlight the need to incorporate the buffering effects of biodiversity to better understand the impact of climate warming on spring leaf unfolding and carbon uptake.

As large-scale approaches to stabilize global mean temperatures pose governance challenges, regional interventions may be more attractive near term. Here we investigate the efficacy of regional MCB in the North Pacific to mitigate extreme heat in the Western United States. Under present-day conditions, we find MCB in the remote mid-latitudes or proximate subtropics reduces the relative risk of dangerous summer heat exposure by 55% and 16%, respectively. However, the same interventions under mid-century warming minimally reduce or even increase heat stress in the Western United States and across the world. This loss of efficacy may arise from a state-dependent response of the Atlantic Meridional Overturning Circulation to both anthropogenic warming and regional MCB. Our result demonstrates a risk in assuming that interventions effective under certain conditions will remain effective as the climate continues to change. Regional marine cloud brightening (MCB) has been proposed as a form of geoengineering. Here the authors show that a regional MCB aiming to reduce warming in the Western United States under today’s conditions would be less efficient under warmer conditions and would exaggerate warming in other regions.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":null,"pages":null},"PeriodicalIF":29.6,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141436188","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}
