The 1.5°C limit and risks of overshoot

Briefings

April 2024

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

Briefings

April 2024

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

Peer-reviewed Papers

March 2024

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.

Climatic risks to adaptive capacity

Peer-reviewed Papers

January 2024

A society’s adaptive capacity determines whether the potential of adaptation to reduce risks will be realised. In this paper, we make the case that climate change itself adds to adaptation constraints and limits.
