This represents the triumph of political science over geophysical science at the NAS. Author Ben Strauss is a fringe climate activist at the Tabloid Climatology site, Climate Central. What the actual data shows is that the rate of sea-level rise is miniscule (in some locations negative!), and the globally averaged rate hasn't increased in over 80 years.
The GLOSS-LTT tide gauge at Wilmington has been measuring sea level continuously since 1935. Over it's full history, the rate of sea level rise at Wilmington has averaged a glacially slow 2 mm/year (about 8 inches per century), and there's been no sea level rise there at all in the last 20 years.
