A Warmer, More Violent Planet

Chris Mooney flags a new meta-study on “the existing research examining the relationship between climate change and violence and conflict”:

[F]or a degree Celsius of temperature increase (1.8 degrees Fahrenheit), [Stanford researcher Marshall Burke] says there could be a 20 percent increase in civil conflict in Africa. The impact of warming varies by region, however; some places are more sensitive to small heat increases than others. In the United States, the estimate would be lower: For 1 degree Celsius of warming, he’d expect about a 1 percent increase in interpersonal conflicts, a category that includes crimes like assault and robbery but also road rage and fights at baseball games.
