Dozens of America’s east coast cities face routine tidal flooding under climate change, researchers said on Wednesday.
Miami – where the habitues of South Beach are used to sloshing through water at high tide – will deploy new pumps this week to hold back the waters of the King Tides, the highest annual high tides, which are projected to crest at 3.5 feet (1.07m).
Other cities are going to have to undertake similar measures if they want to avoid soggy streets in the future, the researchers said.
The report, Encroaching Tides: How Sea Level Rise and Tidal Flooding Threaten U.S. East and Gulf Coast Communities over the Next 30 Years, from the Union of Concerned Scientists (UCS), found most of the towns on America’s east coast will see triple the number of flooding events by 2030.
By 2045, those towns will see 10 times as many tidal floods – and those floods will seep further inland, and last longer, the researchers said.
