Le changement climatique : où en sommes-nous ?

Abstract : Greenhouse gases (GHGs), naturally part of the atmosphere, have protected us from severe glaciations in the past. Today, human activities increase GHG concentrations and cause rapid and unprecedented Earth warming. Climate change is not resumed only to warming, water cycle is also changed. All the researches confi rm: the climate is changing fast, too fast for ecosystems and societies to adapt. Despite the alerts of the international scientifi c community, States gathered into Conferences of the Parties (COP) ratify agreements but do not comply with all their commitments. Public opinion polls indicate that climate change is perceived as a risk, but jobs and taxes override environmental concerns. However, there are local GHG reduction and adaptation initiatives. A territorial approach, on one hand, and global science and negotiations, on the other hand, are two complementary paths that will allow us to consider the impacts of climate change with new forms of solidarity.
