The Hague in the Netherlands was the first city in the world to enact a law prohibiting advertisements for fossil fuel products and services. Although the ban is restricted to The Hague’s jurisdiction, the decision to implement the ban challenges norms and conventions that drive fossil-fuel consumption worldwide and sets an example for other governments to follow.

Urban climate actions have resulted in some progress towards reducing greenhouse gas emissions and adapting human settlements to a warmer planet. However, the long-term implications of climate gentrification threaten the continued efficacy of these actions.

Energy-economic models are increasingly being used to inform climate mitigation policies. This Comment describes three situations where models misinform policymakers and calls for more iterative, policy-orientated modelling exercises that maximize learning in the pursuit of long-term emissions reductions goals.

The IPCC is in its seventh assessment cycle, and international collaboration, which established this organization, is still needed to ensure successful deliverables.

In 2023–2024, widespread marine heatwaves associated with record ocean temperatures impacted ocean processes, marine species, ecosystems and coastal communities, with economic consequences. Despite warnings, interventions were limited. Proactive strategies are needed for inevitable future events.

Critical methodological choices in marine heatwave detection can yield dramatically different results. We call for context-specific methods that account for regional variability to advance marine heatwave research and socio-ecological outcomes.

Governance of domestic cross-border carbon capture and storage faces great challenges, which varies across political systems, economic structures and socio-cultural backgrounds, yet is often overlooked. Overcoming these challenges requires a comprehensive and coordinated approach built on synergistic cluster governance.

Stewardship of soil carbon sits at the nexus of efforts to mitigate climate change, improve soil health and increase climate resiliency of agricultural production. Unlocking the full potential of soils to support a sustainable future requires embracing the unique and contrasting realities of soil carbon dynamics in arid versus humid systems.

Climate research centres provide valuable support to scholars wanting to engage with interdisciplinary research. Fully leveraging this support requires strategic individual efforts. We outline how scholars can achieve collaborative synergy at the intersection of top-down institutional support and bottom-up individual action.
