Climate change poses a financial risk but it is unclear what management role there is for central banks and financial regulators. This Perspective outlines research and policy directions needed for financial sector engagement.
Editorials provide an opportunity for international science journals to exert influence on professional scientists and wider public discourse. Now research shows how editorials on climate change in Nature and Science respond to societal events and reflect the national contexts in which these journals are situated.
Floods are one of the most devastating disasters and their intensity and severity is expected to increase in the future. New research shows how regional floods can cause global impacts through propagation within the global trade and supply network.
Antibiotic resistance is a growing global health crisis. Research now suggests that higher local temperatures are associated with a greater incidence of resistant infections.
Compound events, events of significant impact that are caused by a combination of processes, are difficult to predict. This Perspective discusses the need for a systematic approach to improve risk assessment of these events.
The African continent is one of the most vulnerable regions to future climate change. Research now demonstrates that constraining anthropogenic warming to 1.5 °C instead of 2 °C will significantly lower the risk of heatwaves to inhabitants.
Deforestation often increases land-surface and near-surface temperatures, but climate models struggle to simulate this effect. Research now shows that deforestation has increased the severity of extreme heat in temperate regions of North America and Europe. This points to opportunities to mitigate extreme heat.
Those who distrust climate scientists are more likely to be skeptical of climate change and reluctant to support mitigation policies. Now research shows that scientific interest in early adolescence is associated with increased trust in climate scientists in adulthood irrespective of political ideology.
Low soil moisture conditions can induce drought but also elevate temperatures. Detailed modelling of the drought–temperature link now shows that rising global temperature will bring drier soils and higher heatwave temperatures in Europe.
There is large geographic variation in the public's views about climate change in the United States. Research now shows that climate messages can influence public beliefs about the scientific consensus on climate change, particularly in the places that are initially more skeptical.
For integrated climate change research, the Scenario Matrix Architecture provides a tractable menu of possible emissions trajectories, socio-economic futures and policy environments. However, the future of decision support may lie in searchable databases.
This Perspective reviews the literature on climate change and mental health, and advocates for a systems approach, which considers the complex set of interacting distal, intermediate and proximate factors that influence mental health risk, in future research.
Climate change has a gradual influence on landscapes and ecosystems that may lead to feelings of loss for those with close ties to the natural environment. This Perspective describes existing research on ecological grief and outlines directions for future inquiry.
In the Paris Agreement, nations committed to a more ambitious climate policy target, aiming to limit global warming to 1.5 °C rather than 2 °C above pre-industrial levels. Climate models now show that achieving the 1.5 °C goal would make a big difference for Arctic sea ice.
Permafrost soils store vast quantities of organic matter that are vulnerable to decomposition under a warming climate. Recent research finds that methane release from thawing permafrost may outpace carbon dioxide as a major contributor to global warming over the next century.
Flood impact and recovery is influenced by behavioural responses. This Perspective describes how integrating human behaviour and risk perception into flood-risk assessment models may improve identification of effective risk-management strategies.
The most commonly used method for representing lightning in global atmospheric models generally predicts lightning increases in a warmer world. A new scheme finds the opposite result, directly challenging the predictive skill of an old stalwart.
Environmental scarcity caused by climate change has been implicated as a driver of violent conflict. Now, research shows significant bias in the regions analysed for climate–conflict links. This may limit understanding of the socioeconomic and political conditions in which such conflict occurs, and how these conflicts could be prevented.
People are influenced by second-order beliefs — beliefs about the beliefs of others. New research finds that citizens in the US and China systematically underestimate popular support for taking action to curb climate change. Fortunately, they seem willing and able to correct their misperceptions.
