Nearly 4 million people across the United States, from Los Angeles to much of the East Coast, live in homes more prone to flooding from rising seas fueled by global warming, according to a new method of looking at flood risk published in two scientific papers.
The cities that have the most people living within three feet (one meter) of high tide – the projected sea level rise by the year 2100 made by many scientists and computer models – are in Florida, Louisiana, and New York. New York City, often not thought of as a city prone to flooding, has 141,000 people at risk, which is second only to New Orleans’ 284,000. The two big Southeast Florida counties, Miami-Dade and Broward, have 312,000 people at risk combined.
All told, 3.7 million people live in homes within three feet of high tide. More than 500 US cities have at least 10 percent of the population at increased risk, the studies said.
