Political violence correlates strongly with climate: Civil conflict risk is seven to ten times higher in dry and tropical areas than in continental climate zones. Yet, there is little evidence that climatic variability and change are important in understanding this pattern. The prospect of climate change causing forced migration and food and economic insecurity, meanwhile, raises new concerns about possible future confict scenarios.
