Around the world, extreme weather and water scarcity are accelerating repression, regional conflicts and violence.

They expose cities’ biggest vulnerabilities, inflaming troubles that politicians and city planners often ignore or try to paper over. The effects of climate change are varied and opportunistic, but one thing is consistent: They are like sparks in the tinder. One study predicts that 10 percent of Mexicans ages 15 to 65 could eventually try to emigrate north as a result of rising temperatures, drought and floods, potentially scattering millions of people and heightening already extreme political tensions over immigration.
