Our findings help us better understand both the past and the present, but they are particularly important for what they imply about the future. Many global climate models project global temperature increases of at least 3.6 degrees Fahrenheit (2 degrees Celsius) over the next half century. Our results imply that if nothing changes, this rise in temperature could amplify the rate of group conflicts like civil wars by an astonishing 50 percent in many parts of the world — a frightening possibility for a planet already awash in conflict.

I don't quite think this is the right takeaway here. Isn't it possible that eventually we reach a "new normal"? At some point, there is an upper bound of violence, no?
