  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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 urgency of global action.

  • 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.

  • 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.

  • The desire to justify carbon-emitting behaviours could influence people’s climate change beliefs due to motivated cognition. Based on a pre-registered survey experiment in the United States, the study, however, finds no evidence supporting the claim in explaining climate denial and environmentally harmful behaviour.

  • The authors estimate the global vulnerability of wheat crops to wheat blast under current and future climates. They show that warmer, more humid climates can increase wheat blast infection, particularly in the Southern Hemisphere, subsequently reducing global wheat production.

  • Tropical instability waves (TIWs) are an important component of the equatorial Pacific climate. An analysis of satellite observations, in situ measurements and ocean circulation models indicates that TIW activity has intensified in the central equatorial Pacific by approximately 12 ± 6% per decade since the 1990s.
