Coastal Flood Exposure Analysis

Key Facts

As sea levels rise, flooding is becoming more common along U.S. coasts, where 29% of the population lives.

Climate Central’s Coastal Risk Finder provides maps and analysis of the people, homes, and land at risk from worsening coastal flooding driven by rising seas in the contiguous United States. This report summarizes the projected risk in 2050 from a severe coastal flood. Projections assume pledged commitments to reduce global carbon pollution are met, based on the pollution pathway SSP2-4.5.

Key findings include:

Older adults are disproportionately exposed to coastal flood risk. Nearly 540,000 people aged 65 and older live in at-risk areas.
