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.
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.
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.
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.
Climate warming can impact predators directly as well as indirectly by affecting their prey and habitat. How predators respond to such changes is largely unknown. Now, experimental work shows the ability of spiders to adjust their webs in response to warming-induced changes in plant communities that alter prey size distributions.
Recent US climate bills mark a major step in domestic climate actions, while their successful implementation relies on strong assumptions. This Perspective discusses potential challenges regarding supply, consumer demand and political polarization and how insights of social science could help to overcome these challenges.
Justice issues are integral to a variety of climate science and policy processes. This Perspective provides a framework, based on philosophical theory, to explain key justice concepts and how they can be applied in climate discussions.
Public engagement is necessary for climate action, yet it is difficult to achieve. This Perspective explores three assumptions about public engagement and provides suggestions for overcoming these to facilitate better engagement.
A warming climate can alter the food sources that support animals in Arctic ecosystems. Now, research provides empirical evidence of such a shift, with widespread implications for global carbon cycling.
