Sea level rise will reach 30 cm on US coasts by 2050

(Washington) Sea levels along the coasts of the United States are expected to rise by an average of 25 to 30 centimeters over the next 30 years, equal to the rise measured over the past 100 years, according to a new US report.

Posted yesterday at 3:30pm.

This level will vary by region, according to the US National Oceanic and Atmospheric Agency (NOAA), which led the report to which six agencies contributed in total, including NASA.

Because of these changes, coastal flooding will be more frequent, “even when there are no storms or heavy rain,” NOAA says.

Thus, by 2050, so-called moderately damaging floods will be 10 times more frequent than today – from an event that occurs every 2-5 years to several times a year. “Major” floods will occur at a rate of five times more.

This new data on sea level rise is the latest confirmation of the climate crisis […] “It’s a red alert,” White House national climate advisor Gina McCarthy commented in a news release.

“We must redouble our efforts to reduce the greenhouse gases that cause climate change, while helping coastal communities better adapt to rising sea levels,” she added.

Because of emissions released so far, a sea level rise of 60 cm on the coasts of the United States between 2020 and 2100 is “increasingly likely,” according to the report.

The latter was produced using satellite observations, tide gauge readings, and climate models from the Intergovernmental Panel on Climate Change (IPCC).

In detail, by 2050 sea level is expected to rise between 25 and 35 cm for the east coast of the United States, 35 to 45 cm for the coast of the Gulf of Mexico, and 10 to 20 cm on the coast.

The previous report on this topic dates back to 2017.

“This recent data can guide coastal communities and others.” […] and help them make smart decisions to secure people and property in the long term,” said NOAA Administrator Rick Spinrad.
