What is the relationship between climate change and international crises?

How much do climate change affect the geopolitical order? And on international crises? Massimo Carta and Marzio Chirico will discuss with Antonello Pasini his book Greenhouse effect, war effect: the climate gone mad, migratory waves, conflicts (Chiarelettere 2017) and the climate issue from an unprecedented point of view: the more the climate changes, the more the desert and droughts grow, and the more migratory waves increase. Leaving the task of dealing with climate change to the world's weaker segments is not only unfair but also short-sighted, given the global nature of the issue: becoming aware of the climate emergency can foster a peace, integration and justice operation of unprecedented scope.
