Climate Migration Has Already Begun

The standard framing of climate migration treats it as a future threat. This framing is wrong. Climate migration has already begun, is accelerating, and is shaping real estate markets, political landscapes, and urban planning decisions right now.

The Migration That Does Not Look Like Migration

Climate migration rarely takes the form we expect. More often, it looks like the gradual devaluation of coastal real estate in Norfolk and Miami, the emptying of small agricultural towns in the Central Valley as aquifer depletion makes farming unviable, and the population decline of rural counties where hotter conditions have reduced the economic carrying capacity of the land.

Where People Are Going

Research suggests US climate migration is flowing toward mid-elevation mountain cities, the Upper Midwest Great Lakes region, and secondary Northeastern cities — places with reliable water and moderate summers. This is reshaping those places. Housing costs in Bozeman, Montana, have more than doubled since 2019. Buffalo is experiencing its first sustained population growth in sixty years.

The political implications will take years to fully emerge, but the communities absorbing climate migrants will face infrastructure strain, housing stress, and political tension between long-term residents and newcomers. We are building the plane while flying it.
