Climate change is driving more flooding around the country, and the cost of flood damage to homes can be enormous, according to a pair of new analyses that look at the risks and costs of coastal floods in the U.S.
The findings could hardly be more timely: thousands of households are reeling after floods killed dozens of people in Appalachia and destroyed homes in St. Louis and Arizona last week. And peak hurricane season is looming in the Atlantic.
Flooding associated with sea level rise is accelerating, according to an annual report released Tuesday by the National Oceanic and Atmospheric Administration. Ocean water is inundating coastal cities during high tides, even when there is no storm.
"Sea level rise impacts are happening now, and are growing rapidly," explains William Sweet, a NOAA oceanographer and one of the authors of the report.
The number of days when so-called sunny day floods occur is accelerating on the East and Gulf coasts. For example, in 2021 the Northeast experienced an average of 8 high tide flood days, which is a 200% increase compared to the number of flood days in the year 2000.
