Summary

Jake Bittle wants a different word than "climate migration," and once you read The Great Displacement, you understand why. Migration suggests a choice and a direction. What Bittle documents is a churn, chaotic, forced, and already underway, that he argues will eventually rival the Great Migration of six million Black Americans out of the South in scale.

Three forces drive it, in his account: weather disasters, government policy, and a private housing market that was never built to absorb this kind of shock. None of these operate in a vacuum. Disasters expose fault lines that already existed: underfunded relief programs, housing shortages, insurance markets stretched past their limits. The people with the fewest resources take the hardest hit, and Bittle closes by asking a harder question than where people will go: who decides which places get protected, and which get written off.
