Greenland Ice Sheet
The Greenland ice sheet sits atop the largest island in the world and, as the second largest ice sheet on the Earth, contains the equivalent of roughly 7.4 m of global mean sea level rise. While the ice sheet was likely in balance (i.e., ice mass gain was balancing ice mass loss) during the 1970s, 1980s, and early 1990s, it began to lose mass in earnest beginning in the mid- to late-1990s.
