Nearly everything NASA says about climate is fraudulent, and their claims about sea level are no exception. Their sea level data agreed with the 1990 IPCC report until about 1920, but after 1920 NASA turned a measured reduction in sea level rise rates into an acceleration.
Sea level rise is caused primarily by two factors related to global warming: the added water from melting land ice and the expansion of sea water as it warms.
1990 IPCC : Chapter 9
The 1990 IPCC report said that sea level was rising from 1.0-1.2 mm/year, and had not accelerated in the 20th century.
The criminals at NASA have tripled the rate of sea level rise to 3.24 mm/year.
Hopefully the next president will round up the government climate banditos, and send them riding off into the sunset
