To the Editor:
Marshall Burke, Solomon Hsiang and Edward Miguel argue that their analysis of the literature establishes a strong link between weather and the level of violence in human society. As they know, however, this result has been met with some skepticism in specialist circles.
On the other hand, there is universal agreement that poverty, inequality and weak civil institutions are at least as important as weather in explaining levels of violence.
Policy makers must not lose sight of this in all the excitement about climate change.
