Workshop on "combined extreme events" at the actuaries' congress
At the 25th actuaries' congress, the Geolearning chair will host a workshop dedicated to extreme weather events
The Geolearning Chair held a scientific conference at Mines ParisTech on April 8, 2026. The conference was divided into two parts. The first part presented the various projects supported by the Chair. The second part focused on the state of the art and emerging challenges. The slides from the presentations are available below:

Conference on stochastic weather generators
The Geolearning Chair is contributing to the organization of the conference on Stochastic Weather Generators, which will be held in Grenoble from December 2nd to 4th, 2025. This international workshop aims to explore cutting-edge methods and emerging challenges for simulating weather variables: precipitation, temperatures, etc.
