From global solution space to local strategies: integrating adaptation pathways and global scenarios for water scarcity

At COP28, Climate Analytics Caribbean launched a proposal for a Regional Goal on Adaptation for the Caribbean to ensure local climate change realities can be included in adaptation priorities, targets and needs. This technical paper, launched at COP30, outlines the updated proposal.

As climate change continues to accelerate, its multifaceted impacts will affect societies across the globe in increasingly complex and uneven ways. This study provides a comprehensive assessment of how socioeconomic factors interact with climate vulnerability up to the year 2100.

New perspective piece argues climate overshoot – the temporary exceedance of the 1.5°C limit of the Paris Agreement – may not be relevant for short-term adaptation planning, but it should be considered for long-term plans and policies, such as infrastructure-based measures and for irreversible impacts such as sea-level rise.

With critical physiological limits to human heat tolerance drawing ever closer, this Comment highlights the urgent need to limit further climate warming and emphasises the adaptation challenge ahead.

With international efforts on climate action still not on track to limit warming to 1.5°C, technological fixes that aim to intentionally alter the Earth’s climate, such as solar geoengineering, might seem like appealing options for tackling global warming. But they come with questions in terms of feasibility, impacts and risks, governance and geopolitics, and who may or may not benefit.

This technical guide proposes concrete steps and actions to help African countries develop strong, high-performing Long-Term Low Emission and Climate Resilient Development Strategies that chart a low-emission development path, build resilience, encourage innovation, and create new opportunities for green growth.

The authors propose creating an international federation of research institutions that improve the quality and accessibility of Earth systems data. The purpose is to empower all people to respond to the immense and urgent challenges posed by climate change.

This briefing looks at what the 1.5°C limit means in terms of adaptation and loss and damage for the most vulnerable countries and regions. It finds that slowing down warming is critical to buy us time to adapt and also to avoid irreversible loss and damage. Even if warming rises above 1.5°C (overshoot) we can bring it down again with ambitious emissions reductions.
