The study, issued on Tuesday, expected that sea levels on the US coast would increase between 25 and 30 centimeters by 2050.
In addition to the more frequent flooding of beaches during storms, rising sea levels increases tidal flooding.
Nicole Lebov, director of the oceans division at the US National Oceanic and Atmospheric Administration, said devastating coastal flooding would increase 10 times within 30 years.
“I can tell you with complete confidence that this is not the kind of change we grew up with,” she added.
The study, which comes as part of planning efforts to confront and adapt to the expected rise in sea levels, shows a high degree of certainty about the next three decades, regardless of any efforts to contain greenhouse emissions that increase the temperature of the planet.
“This new data on rising seas is the latest confirmation that the climate crisis, as the president said, has raised the red flag of danger,” said Gina McCarthy, climate advisor to President Joe Biden.
