Nature Climate Change, Published online: 05 March 2024; doi:10.1038/s41558-024-01940-4 In a changing climate, tree trunks serve as crucial refuges for animals, particularly ectotherms, seeking to escape extreme climatic conditions. Therefore, while climate change could generally promote population growth among ectotherms, deforestation could reverse these positive effects in some populations or exacerbate the negative impacts of…
Nature Climate Change, Published online: 05 March 2024; doi:10.1038/s41558-024-01939-x The authors develop a biophysical model to understand the impacts of tree loss and climate change on the activity patterns and population trends of a diurnal ectotherm (lizard). They show that deforestation can reverse the positive effects of climate change and even accelerate population declines.
Nature Climate Change, Published online: 01 March 2024; doi:10.1038/s41558-024-01950-2 Increasing exposure to climate hazards under climate change will disproportionately impact poor communities. This study shows that disruptions to infrastructure service threaten progress towards the Sustainable Development Goals in coastal Bangladesh, but impacts can be mediated through adaptation.
Nature Climate Change, Published online: 27 February 2024; doi:10.1038/s41558-024-01946-y The authors use stomach contents from six fish species sampled for 12 years to show that warming shifts foraging behaviour to favour consumption of less energetically rewarding prey. Using food web models, they show that this flexible foraging could lead to reduced community biodiversity.
Nature Climate Change, Published online: 20 February 2024; doi:10.1038/s41558-024-01943-1 International trade of used vehicles lacks regulation on emissions standards. This study shows that vehicles exported from Great Britain generate substantially higher carbon and pollution emissions than scrapped or on-road vehicles.
Nature Climate Change, Published online: 16 February 2024; doi:10.1038/s41558-024-01942-2 Local governments need extensive funding to realize transformative climate ambitions and this raises the spectre of privileging outside interests over just transitions. Now, research unearths how such private financial interests shape city climate actions in ways both broader, and potentially more brittle, than previously understood.
Nature Climate Change, Published online: 16 February 2024; doi:10.1038/s41558-024-01924-4 City fiscal and budgetary decisions play an essential role in the success of urban climate action. Using US cities as a case study, this Article reveals the interrelationship between urban climate finance, action and justice, as well as promising pathways to transform municipal finance practices.
Nature Climate Change, Published online: 16 February 2024; doi:10.1038/s41558-024-01929-z Building additional water infrastructure such as wells is a key strategy to mitigate the impacts of severe droughts, particularly in drylands. This study shows, however, that this infrastructure can lead to loss of resilience under climate change due to erosion of traditional practices.
Nature Climate Change, Published online: 14 February 2024; doi:10.1038/s41558-024-01938-y Methane concentrations are rising faster than ever in the atmosphere. Now, a compilation of observations points towards increased methane emissions from Arctic wetlands as being partly responsible.
Nature Climate Change, Published online: 14 February 2024; doi:10.1038/s41558-024-01933-3 Whether methane emissions from the Boreal–Arctic region are increasing under climate change is unclear, but critical for determining climate feedbacks. This study uses observations and machine learning to show an increase in wetland methane emissions over the past two decades, with inter-annual variation.
Nature Climate Change, Published online: 09 February 2024; doi:10.1038/s41558-024-01925-3 Global support and cooperation are necessary for successful climate action. Large-scale representative survey results show that most of the population around the world is willing to support climate action, while a perception gap exists regarding other citizens’ intention to act.
Nature Climate Change, Published online: 08 February 2024; doi:10.1038/s41558-024-01927-1 Carbon sequestration in mangroves has been proposed as a mitigation strategy for climate change, yet the benefits of carbon burial may be offset by methane emissions. This study shows that methane offsets are small in saline and tropical mangroves, leading to greater net carbon sequestration.
Nature Climate Change, Published online: 05 February 2024; doi:10.1038/s41558-023-01921-z Oceans, covering more than 70% of Earth’s surface, play a vital role in regulating the climate by absorbing heat and carbon dioxide. Now research shows oceans have warmed by more than 1.5 °C since the beginning of the industrial era, challenging previous estimates and emphasizing the…
Nature Climate Change, Published online: 05 February 2024; doi:10.1038/s41558-023-01919-7 Understanding temperature change since the pre-industrial period is essential for climate action. This study uses an ocean proxy to better quantify when anthropogenic warming began and estimates that global temperatures have already increased by 1.7 °C.
Nature Climate Change, Published online: 02 February 2024; doi:10.1038/s41558-024-01932-4 In this issue of Nature Climate Change, we publish our first Registered Report. We encourage scientists from all climate research communities to consider this format in the future.
