One week for professional academic research mathematicians wanting to understand topics related to climate change in order to include them in their teaching, their life and their profession at large. The mathematical community can thus help bridge the gaps between IPCC scientists, the academic community and the general public. This week will be in French and participants will come by train. If you wish to organize a similar event in English somewhere else, the organizers will be happy to help you copy this event, please feel free to contact us.
