Abstract

The 21st International Climate Conference (COP21) demonstrated that a global consensus is possible among 195 countries. For this reason, we could say that climate change is a chance (perhaps the last) for humanity.It is indeed the only area where worldly governance now seems possible, although it also is needed to fight, for example, against global terrorism or to regulate international migration. - Through the ongoing experience concerning climate policy, a triple dynamic, which would establish a genuine global governance, can be drawn: recognizing interdependencies, regulating contradictions, making actors aware of their responsibilities. It is therefore urgent we learn the lessons of the COP 21.
