New study finds ‘alarming’ high flood risk for 17 million Americans on Atlantic and Gulf coasts
Researchers used artificial intelligence and FEMA damage data to map flood exposure, finding 17.5 million people at very high risk and 17 million at high risk.
- A new study published Wednesday in the journal Science Advances reveals 34.5 million residents along the U.S. Atlantic and Gulf coasts face high or very high flood risk, with researchers calculating 17.5 million at very high risk.
- University of Alabama researchers utilized 16 distinct factors to determine flood risk, incorporating sinking land, pavement density, and social vulnerability including age and poverty levels.
- New York City has 4.75 million people at high risk with more than 200,000 buildings likely damaged, while New Orleans faces threats to 99% of its population, affecting about 380,000 residents.
- "When the next big storm hits New York City, people will get hurt, especially those socially vulnerable populations," said climate scientist Wanyun Shao, calling the numbers "shocking" and "alarming."
- University of Virginia professor Venkataraman Lakshmi said flooding problems will intensify due to human-caused climate change, recommending natural infrastructure like wetlands and rain gardens to mitigate future risks.

These eight coastal cities sit on America's flood front line, and AI shows why
New York, New Orleans and Miami are among the eight cities along the US Gulf and Atlantic coasts facing the highest flood risk, according to a new study published in Science Advances. Scientists developed a new AI-driven framework and combined it with historical flood-damage data to not only identify high-risk coastal areas but also pinpoint the underlying factors driving that risk.
