This level will vary depending on the region, specifies the American National Oceanic and Atmospheric Agency (NOAA), which led this report to which six agencies in total, including NASA, contributed.
Because of these changes, coastal flooding will be much more frequent, "even in the absence of storms or heavy rainfall", underlines the NOAA.
Thus, by 2050, so-called moderate floods causing damage will be on average ten times more frequent than today – going from an event occurring every 2 to 5 years to several times a year.
And "major" floods will occur five times more frequently.
"These new data on sea level rise are the latest confirmation that the climate crisis (...) is a red alert", commented Gina McCarthy, national adviser on climate at the White House, quoted in a statement.
"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 the emissions released so far, a sea level rise of 60 centimeters on US coasts 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, sea level rise by 2050 is expected to be 25 to 35 cm for the US East Coast, 35 to 45 cm for the Gulf of Mexico coast, and 10 to 20 centimeters on the Where is.
The previous report on the subject dated back to 2017.
"This up-to-date data can guide coastal communities and others...and help them make smart decisions to keep people and property safe for the long term," said NOAA Administrator Rick Spinrad.
