22 Apr
Summary
- Over 17 million people on US coasts are at very high flood risk.
- New York and New Orleans identified as cities with extreme vulnerability.
- Study integrated 16 factors using AI for comprehensive flood risk assessment.

A groundbreaking study reveals that more than 17.5 million individuals residing on the U.S. Atlantic and Gulf coasts are at a "very high" risk of experiencing flooding. An additional 17 million people are classified as being at "high" risk. The research, conducted by scientists at the University of Alabama, employed 16 distinct factors and three artificial intelligence tools to assess flood vulnerability.
New York City and New Orleans were highlighted as particularly vulnerable locations. New York City faces potential damage to over 200,000 buildings, with 4.75 million people at the two highest risk levels. While New Orleans has fewer people at risk, approximately 380,000, this represents 99% of its population, underscoring its significant exposure.
