The Rising Threat: Climate Abandonment and Migration Patterns in America

A new study by the First Street Foundation reveals that over 16 million people in the contiguous US, approximately 5% of the population, reside in "climate abandonment areas" characterized by increasing flood risk and declining populations. These areas, found throughout the country, are particularly vulnerable to climate-related disasters such as heavy rainfall, tropical cyclones, and coastal and river flooding. The research highlights that people are becoming more cautious about where they choose to live, avoiding high-risk areas. The study also identifies "risky growth areas" where populations continue to grow despite rising flood risk. The findings underscore the urgent need to address the population exposure and migration challenges posed by climate change.
