“New Data Show an ‘Extraordinary’ Rise in U.S. Coastal Flooding”

“Rising seas are bringing water into communities at record rates, the National Oceanic and Atmospheric Administration said Tuesday.”

“WASHINGTON — Parts of the United States saw record levels of high-tide flooding last year as rising seas brought water further into coastal homes and infrastructure, government scientists reported Tuesday.

The increase in high-tide flooding along the Atlantic and Gulf Coasts since 2000 has been “extraordinary,” the National Oceanic and Atmospheric Administration reported, with the frequency of flooding in some cities growing fivefold during that time. That shift is damaging homes, imperiling the safety of drinking water, inundating roads and otherwise hurting coastal communities, the agency said.

“Conditions are changing, and not just in a few locations,” Nicole LeBoeuf, acting assistant administrator for NOAA’s National Ocean Service, which compiled the report, said during a call with reporters. “Damaging floods that decades ago happened only during a storm now happen more regularly, even without severe weather.””
