The triple climate inequality crisis, or disparities in contributions, impacts and capacity to act within and between countries, is a central issue in addressing climate change. This Comment advocates for progressive wealth taxation as a viable solution to the finance gap.

Policies and psychological approaches often overemphasize individual agency, overlooking how socioeconomic inequality can constrain access to low-carbon alternatives. We argue that tackling these inequalities is urgent for impactful, equitable behaviour change.

Communal life is characterized by the shared timing of human and environmental events. Climate change is disrupting these timings, creating mismatches in these coordinated temporal patterns and requiring adaptive governance.

Recent criticisms have suggested that future emissions are unlikely to lead to the warmest climate scenario available (SSP5–8.5), which has resulted in the second highest scenario (SSP3–7.0) receiving increased attention. The distinctiveness of SSP3–7.0 has not been well recognized, but it is relevant for the proper interpretation of studies that use this scenario.

If rapid and just transformations to low-carbon societies are to take place, citizens need to obtain the necessary knowledge and skills to critically examine and choose adequate climate policy options. An emphasis on critical climate education research and implementation is therefore required.

Extreme weather event attribution techniques quantify anthropogenic contributions to extreme weather disasters, but recently it was argued they are not yet ready to inform decisions on loss and damage funding. Here, we assert that they can substantially help formulate allocations to impacted vulnerable countries for the most damaging extreme events.

Climate models have evolved from research tools to underpin decision-making across the globe. To provide optimal value for society in the future, the models need to be made operational.

Climate education is seen as a key driver for behavioural change, yet it is usually not continued universally to higher-education level. With the increasing demand from both students and employers, we propose methods that incorporate climate education from multiple disciplines into current curriculums.

Climate emotions permeate student learning and research activities, but their influence is poorly understood and often ignored in higher education. We develop recommendations for instructors, research mentors and institutional leaders to enhance educational and research outcomes for students grappling with challenging climate emotions.

Climate change education is crucial to countries in the Global South due to their contribution and vulnerability to the climate crisis. However, institutionalizing and implementing climate change education is particularly challenging in developing nations, given inadequate motivation and limited capacity.

The global stocktake (GST) could both enable and hamper the inclusion of equity. This Comment outlines why equity is central to the GST and the challenges faced in addressing it, as well as the utility of needs-based assessments for advancing equity within the GST and the climate action generally.

Ice melt processes that take place at the ice–ocean boundary of Greenland and Antarctic glaciers play a pivotal role in their evolution and contribution to sea-level rise, but widespread observations in these regions are lacking. A major observational initiative will be necessary to drastically reduce uncertainties in projections and better prepare society for sea-level rise.

Better integration of climate action and sustainable development can help enhance the ambition of the next nationally determined contributions, as well as implementation of the Sustainable Development Goals. Governments should use this year as an opportunity to emphasize the links between climate and sustainable development.

Non-state actors play an essential role in the fabric of global climate governance. Here we propose four tailored strategies that non-state actors can mobilize to advance climate action among states and harness the potential of the global stocktake.

The global stocktake seeks to enhance climate ambition through assessment and review of collective efforts every five years. A recent breakthrough in finance for addressing loss and damage is an opportunity to strengthen the finance agenda and rebuild much needed trust in the multilateral system.

Inconsistent climate projections for much of the Global South from six generations of IPCC assessments have compounded the many challenges it faces in adapting to climate change. Here, we propose using emerging technologies and strengthening international collaborations to address these challenges.

There are contrasting views on how to produce the accurate predictions that are needed to guide climate change adaptation. Here, we argue for harnessing artificial intelligence, building on domain-specific knowledge and generating ensembles of moderately high-resolution (10–50 km) climate simulations as anchors for detailed hazard models.

Climate change research and assessments, including the most recent IPCC report, paint an increasingly dire picture of the future. However, the assumption that the future will be worse than the present may be wrong for many aspects of human well-being.

The IPCC has been successful at building its scientific authority, but it will require institutional reform for staying relevant to new and changing political contexts. Exploring a range of alternative future pathways for the IPCC can help guide crucial decisions about redefining its purpose.

Climate change has been identified as a driver of instability and conflict around the world. However, how climate change and the transition to a net-zero world might alter the character of military operations is often overlooked.
