The transition to net-zero emissions will be contested and could lead to political polarization and social unrest. To contribute to a transition that is accepted as legitimate while remaining effective, research on public support must evolve rapidly along several dimensions.

Floating ice shelves that fringe Antarctica are at risk from warming ocean water and from above by warming air. Work now reveals that snow accumulation on ice shelves can minimize surface melt and ponding, but that future atmospheric warming will likely overpower this protection that snow provides, leaving ice shelves vulnerable to collapse.

Melt ponding is an important process for the stability of ice shelves. Here the authors estimate the temperature thresholds at which melt ponding emerges over Antarctic ice shelves and find that cold and dry ice shelves are more vulnerable to melt ponding than expected.

Statistical analysis of a climate institutions dataset has identified four national models of climate governance used across countries with high emissions. These models are associated with the climate policy ambition and performance of each country. This analysis reveals that the effectiveness of climate policymaking could be strengthened by building climate institutions.

National climate institutions could greatly impact the process of policy design and implementation. This analysis identifies four models of climate governance for major emitters, estimates their policy ambitions and performance, then shows how they are related to macro features.

A changing climate is altering vegetation phenology and probably impacts drought frequency and severity. Changes in vegetation phenology have some unexpected consequences on the trajectories of drought recovery.

The authors reveal complex drought recovery responses to phenology shifts, in that early spring can shorten or lengthen recovery, while delayed spring following drought events delays it. These effects suggest a need to incorporate phenology aspects into resilience models.

How the spatial structures of large storms will change is not well resolved in most climate models. Here the authors use high-resolution models to show that winter storms become sharper under warming because precipitation in the storm centre increases more strongly than the storm area.

Reducing methane emissions from fossil fuels, agriculture and waste is key to achieving climate goals. Technological advances and scientifically grounded feasibility assessments of mitigation initiatives may illuminate the path to success.

The Hunga Tonga–Hunga Ha’apai eruption in January 2022 injected large amounts of water vapour into the atmosphere. Here, the authors show that this can cause additional warming over the next years, which increases the likelihood of exceeding 1.5 °C warming over a short time period.

Rapid growth of AI could lead to more inventions and innovations in climate actions, yet evidence of this connection is lacking. The use of large-scale patent data and automated techniques helps elucidate trends in climate-related artificial intelligence inventions for different technology areas.

Snow is an important component of the environment and climate of mountain regions, but providing a long-term historical context for recent changes is challenging. Here, the authors use ring-width data from shrubs to show that recent snow loss in the central Alps is unprecedented over the last 600 years.

High uncertainty exists in the projected climate change impacts on the Nile’s economies and water-dependent sectors. Under these uncertainties, managing the Grand Ethiopian Renaissance Dam cooperatively and adaptively can produce economic and water management benefits for Ethiopia, Sudan and Egypt.

Despite the trajectory towards climate catastrophe, governments are failing to take disability-inclusive climate action. We discuss how the scientific community could advance and hasten the development of disability-inclusive climate resilience, and which areas should be prioritized.

Partisan politics is characterized by pejorative generalizations across opposition groups, but, similar to the groups being derogated, not all partisans are the same. Understanding the nature of partisan opposition to climate policy may help promote bipartisan projects to mitigate climate change.

Partisan polarization plays a key role in shaping climate action in the United States. By identifying positive and negative elements within party identities, the authors expand conceptualizations of Republican-Democrat to explore how partisanship relates to policy support and behavioural intentions.
