Bullet-Point Summary:

Climate activists, including government bureaucrats, claim the Greenland ice sheet is melting six times faster than it was 30 years ago.
Thirty years ago, the Greenland ice sheet was barely melting at all. “Six times” almost no ice loss remains almost no ice loss.
When recent ice loss is compared to the full Greenland ice sheet, the loss is so small that it is almost undetectable.
Sea-levelmeasurements contradict claims that Greenland ice loss threatens coastal flooding. NASA satellite instruments, with readings dating back to 1993, show global sea level rising at a pace of merely 1.2 inches per decade, which is not significantly different than the typical rate of sea-level rise since the mid-1800s.

Short Summary: NASA scientists and media pundits have said this about the Greenland and Antarctic ice sheets: “The two regions have lost 6.4 trillion tons of ice in three decades; unabated, this rate of melting could cause flooding that affects hundreds of millions of people by 2100.” However, that is far short of even 1 percent of Greenland’s ice mass. As shown in the right graph in Figure 1, below, the total ice loss each year is a nearly undetectable five one-thousandths of one percent (0.005 percent) of the Greenland ice mass.
