La pollution est la destruction ou dégradation d’un écosystème ou de la biosphère par l’introduction, généralement humaine, d’entités (physiques, chimiques ou biologiques), ou de radiations altérant le fonctionnement de cet écosystème1. La pollution a des effets importants sur la santé et la biosphère, comme en témoigne l’exposition aux polluants et le réchauffement climatique qui transforme le climat de la Terre et son écosystème, en entraînant l’apparition de maladies inconnues jusqu’alors dans certaines zones géographiques, des migrations de certaines espèces, voire leur extinction si elles ne peuvent s’adapter à leur nouvel environnement biophysique.

A new study uncovers Earth’s deep temperature history and shows just how tightly carbon dioxide has always controlled the climate
In response to global climate change, other systems, such as global oceanic circulations, could collapse, with devastating consequences. When it comes to battling climate change, some people think that the only issue we may be facing is that the climate may get a few degrees warmer. And, of course, if you live in rather cold areas on Earth, you wouldn’t mind some extra warmth. Even if you live in a temperate region, you may be inclined to think that 1.5 to 3 °C may not be such a big deal after all. […] But there is much more to climate change than warming temperatures. For example, in a previous story, I talked about how, by studying fossil records, we discovered the catastrophic chain of events following increased greenhouse gas emissions and global warming. The list goes on and on, from ocean acidification and anoxia to droughts and mass extinctions.
