Une équipe internationale de 59 scientifiques de 17 nations vient de publier un rapport dans la revue Nature Geosciences. Leur constat est terrible : le réchauffement de la planète pourrait être le double de ce que prédisent les modèles climatiques. Ce sont des mécanismes d’amplification, mal représentés dans les modèles, qui

La production de masse de matière plastique a commencé il y a une soixantaine d’années. Dans ce laps de temps, celle-ci s’est considérablement accélérée, générant plus de 8 milliards de tonnes. Une tonne par être vivant sur cette planète ! Le problème, c’est qu’une petite dizaine de pourcent seulement de cette
