The 1.5°C limit

The 1.5°C warming limit is the cornerstone of ambitious climate action. The science tells us keeping within this limit is feasible and is essential if we are to avoid permanent and devastating climate impacts.

We have pioneered science detailing the impacts of warming at 1.5°C compared to higher levels of warming to illustrate the relevance and urgency of climate action. Our policy analysis and advice is also framed around this limit to set out what climate action in line with the best science looks like from national to global levels.
