More than 16 million people in the contiguous US — roughly 5 percent of the population — live in a place with heightening flood risk and a shrinking population, according to new research. It makes the case that “climate abandonment areas” are becoming a more prevalent phenomenon in the US as people avoid places particularly vulnerable to climate-related disasters.
What’s a climate abandonment area? It’s a census block where flood risk has grown high enough to start pushing people to leave. Many of these areas lie along the Texas Gulf Coast, coastal Florida, and the mid-Atlantic.
