I read the NASA report and it says no such thing. The global sea level is rising, but it has been rising at a very constant rate for as long as we have been measuring it, and as near as we can tell, as far back as after the last ice age peaked and the glaciers started melting instead of growing. Just check the NOAA tide station data to chart the trends and you see straight-as-a-ruler trend lines from beginning to end -- including the station at Brest, France which began operation in 1807.

Examine the tidal trend for Galveston, TX: https://tidesandcurrents.noaa.gov/sltrends/sltrends_station.shtml?id=8771450. This shows a sea rise of 6.59 mm/yr or 122.57 mm (4.8 in) for every 18.6-year lunar cycle. This means that at the next lunar peak, Galveston can expect about 4.8 inches higher highs than the current lunar peak. But it also means that the current tidal peak should be about 4.8 higher than the last cycle -- which were 4.8 inches higher than the cycle before that one, and so forth.

This trend has held rock steady for over a century. There has been no increase in this trend at all, much less at an "unprecedented rate." (There is no mention of an increased rate in the NASA article.)

This means that, for some coastal areas, this increase will eventually reach a level that will become problematic. But some coastal areas will feel the effect before others. The Gulf of Mexico is just one such area because, along with the steady rise of sea level, the land is actually subsiding, or sinking lower. So areas like Galveston will see higher sea levels from 3 to 10 times the global average. Brest, France, for example, will see only a 0.769-inch increase at the next lunar cycle -- very close to the global average.
