4:20 – Closure by Dominique MARBOUTY Vice-President of Météo et Climat

Losses due to extreme weather and climate events are increasing worldwide, and some extreme events in the last decade have been particularly devastating. For example, since 2015, Western Europe has not had a summer without an extreme heat wave. It is therefore important to understand whether the various events are linked to climate change and whether there is an urgent need to strengthen adaptation.

Society, infrastructure and natural systems are adapted to a range of climates, and adaptation is often calibrated on historical data. But the climate has already changed and it is time to re-examine climate risks.

This conference will bring together a multidisciplinary panel of experts from the climate and social sciences as well as policy makers.
It will explain the role of climate change in recent extreme events, how this informs current and future climate risks and how society and stakeholders should interpret this information.
