With climate change impacts increasingly being felt by more of the world’s population, adaptation efforts are urgently needed. However, similar to the unequal distribution of climate change impacts, the ability of societies to adapt is also heterogeneous.

Studies on sea-level rise often claim to be useful for local decision-makers and adaptation planning. We asked researchers and practitioners to discuss the different ways in which science can inform local to global decision-making and what researchers can do to improve the utility of their findings.

A net-zero change in tree cover is often considered to have no impact on the biophysical effects of forests. Satellite observations now reveal an asymmetric influence of gross tree-cover gain versus loss on land surface temperature. Neglecting this influence might lead to biases in quantifying the biophysical effects of forests.

Climate change might alter mosquito-borne disease risk, but research now suggests that one emerging mosquito control approach might be largely resistant to warming temperatures.

The biocontrol technology (wMel) used to mitigate mosquito-borne viruses is adversely affected by heat stress. The authors integrate empirical data on mosquito population dynamics and wMel thermal sensitivity to show that the technology is generally robust to near-term climate change.

Satellite radar altimetry enables the detection of sea-level changes by collecting data that have exceeded early expectations. This Perspective discusses potential advances that would enhance the data, allowing regional detection and attribution of sea-level change and improving ocean heat uptake estimates.

Changes in tree cover can change surface temperatures in multiple ways. Here, the authors show an asymmetric direct biophysical effect of tree cover change, as the cooling due to tree cover gain is greater in magnitude than the warming from tree cover loss in most forests.

A gap persists between the emissions reductions pledged by countries under the Paris Agreement and those resulting from their domestic policies. We argue that this gap in fact contains two parts: one in the policies that countries adopt, and the other in the outcomes that those policies achieve.

Planned relocation can be an adaptation approach to avoid damages from increasing natural hazards yet concerns over maladaptive outcomes remain. Based on flood-related relocation cases, this study highlights the importance of community engagement in enabling sustainable livelihoods.

Natural disasters can trigger conflictive behaviour among affected individuals. Now, research based on survey experiments with Syrian and Iraqi refugees shows how people behave altruistically after experiencing drought, but only towards ingroup members.

Nature-based solutions, such as urban green spaces, are shown to contribute to carbon emissions reduction and carbon sequestration, and also to have valuable indirect effects and behavioural impacts. Implementing such solutions could achieve carbon neutrality within the decade in several major cities in Europe.

Climate-induced extreme events could lead to drastic socioeconomic consequences, including altered cooperation behaviours. With survey experiments among Iraqi and Syrian refugees, this study finds drought experience could reduce altruism and group identity function as the key moderator.

The impacts of microclimate on future plant population dynamics are poorly understood. The authors use large-scale transplant climate change experiments to show the contribution of forest microclimates to population dynamics and project the distributions of 12 common understorey plants.

We established a comprehensive assessment framework to explore the carbon dioxide (CO₂) emissions reduction potential from coal–biomass co-firing power plants with retrofitted carbon capture and storage (CBECCS) in China. Optimal spatiotemporal deployment of the CBECCS transition could achieve CO₂ mitigation of 1.6 Gt yr⁻¹ in 2040 and 41.2 Gt cumulatively over the period 2025–2060.

The narrative that certain areas will inevitably become uninhabitable owing to sea-level rise is powerful, yet may silence important debate about alternative climate adaptation futures. In particular, populations with low emissions and funding capacity should have their narratives centralized in adaptation.
