“The relative sea level trend is 2.39 mm/year with a 95% confidence interval of +/- 0.43 mm/year based on monthly mean sea level data from 1931 to 1981 which is equivalent to a change of 0.78 feet in 100 years.”
The last time I did the math (it's been a while now), assuming that I did this correctly it showed that the current rate of sea level rise is something like half the average rate of the last ten to fifteen thousand years. So the current rate would basically have to double just to get us back to the long-term average. And it might very well do that someday, and do so perfectly naturally, too. (Nobody has ever said that the natural rise in sea level has stopped since the beginning of the last interglacial period.) But that wouldn't be good news for places like Miami.
That's a false description of what NOAA says. The sea level trend is an instantaneous rate, not a projection of any sort.
