Replay of the lecture held on March 25, 2025 at the Médiathèque José Cabanis in Toulouse, by Cathy Clerbaux, Director of Research at CNRS, Professor of Atmospheric Sciences, member of AAE.
The media regularly report that the state of the atmosphere is getting worse, and that man is primarily responsible.
