Extreme weather events in 2023 illustrated how poorly prepared the world is for the growing risks of climate change. Nowadays it is possible to use attribution science to investigate the role of climate change and other factors in specific weather and climate extremes. Attribution studies estimate by how much a specific extreme event was made more (or less) likely and/or intense because of climate change. This policy brief summarizes key learnings from the first two years of the XAIDA project and formulates recommendations.
