The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2021 “for groundbreaking contributions to our understanding of complex physical systems” with one half jointly to
Syukuro Manabe, Princeton University, USA and Klaus Hasselmann, Max Planck Institute for Meteorology, Hamburg, Germany “for the physical modelling of Earth’s climate, quantifying variability and reliably
predicting global warming” and the other half to Giorgio Parisi, Sapienza University of Rome, Italy “for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales.”

Michael Ghil and Hervé Le Treut shall summarize highlights from the work of Klaus Hasselmann and Syukuro Manabe. More importantly, we shall try to give a better idea of the importance of this prize for the climate sciences: how they are practiced and how they communicate with other sciences, physical, biological and socio-economic.

Le séminaire ne sera a priori par rediffusé en visio, mais un enregistrement sera peut-être disponible ultérieurement.
