Adaptation is often a context specific and localised process which can result in global climate adaptation negotiation processes being relatively disconnected from the local climate change realities that vulnerable communities face in Caribbean small island states (SIDS).

In this regard, Climate Analytics Caribbean launched a proposal for a Regional Goal on Adaptation (RGA) for the Caribbean at COP28 through a participatory and inclusive approach whereby Caribbean civil society stakeholders defined the priorities, targets and needs for adaptation in the region.

Over the past eighteen months, Climate Analytics Caribbean has continued to revise and update the proposed RGA to align with current developments in the global climate change negotiations, relevant regional and national climate adaptation policies and strategies as well as further consultations with diverse Caribbean stakeholders.

This technical paper outlines the updated proposal for the Caribbean which was launched at COP30 in Belem in November 2025. The updated proposed RGA consists of fourteen high level targets comprising eight thematic targets and six dimensional targets which are grounded in Caribbean realities and priorities. The updated RGA intends to raise the visibility of adaptation in the Caribbean, quantify and fill adaptation gaps and needs including finance, capacity and technical assistance and enable collective review of progress on adaptation through more effective climate governance processes and practical adaptation actions at the local, national and regional levels.

The updated RGA could serve as a regional vehicle to support achieving the Global Goal on Adaptation and the UAE-Belem Global Resilience Framework through regional leadership and collaboration on adaptation. In so doing, the updated RGA seeks to bridge the gap between Caribbean adaptation actors and activities at the regional, national, local levels and the broader GGA discussions at the international level. The updated RGA proposal also provides an initial overview of RGA implementation requirements including financing, coordination, further refinement activities. A preliminary implementation roadmap is also outlined to support the operationalisation of the updated RGA.

Climate overshoot implications for local adaptation planning

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.

Adapting East and Southern Africa’s livestock to climate change

This paper presents a decision-making framework to help livestock farmers in Eastern and Southern Africa select context-specific adaptation strategies in response to climate change. The framework uses a decision tree to evaluate options based on different climate scenarios and systems, offering tailored guidance for various livestock types and regions.

Solar geoengineering: a note to inform discussions on physical climate impacts, risks and governance issues

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.

Technical guide for the development of long-term low emission development strategies in Africa

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.

A review of loss and damage in the Caribbean (1994 to 2024)

Loss and damage from climate change has been the lived reality of Caribbean small island developing states (SIDS) for decades. Despite efforts to adapt, it is reversing development gains, leaving lasting financial stress, and causing irreparable damage, including the loss of cultural heritage. This report is the first to provide a systematic overview of how Caribbean countries are framing and reporting on loss and damage.

The 1.5°C limit and risks of overshoot

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.

Le seuil de +1,5°C et le risque de dépassement de ce seuil

Ce rapport examine ce que la limite de 1,5 °C signifie en termes d'adaptation et de pertes et dommages pour les pays et régions les plus vulnérables. Il constate qu'il est essentiel de ralentir le réchauffement pour nous donner le temps de nous adapter et pour éviter des pertes et des dommages irréversibles. Même si le réchauffement dépasse 1,5 °C, nous pouvons le faire baisser à nouveau en réduisant les émissions de manière ambitieuse.

Effectiveness of water-related adaptation decreases with increasing warming

When it comes to water, adaptation to climate change becomes less effective when warming is above 1.5°C, according to a new study looking at water-related climate risk at 1.5°C, 2°C, 3°C, and 4°C of warming. The study finds adaptation needs to go hand-in-hand with ambitious emissions reductions and decarbonisation.
