NASA studies confirmed accelerating net shrinkage of the Greenland ice pack used Gravity Recovery and Climate Experiment (GRACE) satellite data. Melting of the ice pack has increased since the 1990's.
According to Science Daily, study co-author Jay Zwally said:
"In the 1990's, the ice sheet was growing inland and shrinking significantly at the edges, which is what climate models predicted as a result of global warming. Now the processes of mass loss are clearly beginning to dominate the inland growth, and we are only in the early stages of the climate warming predicted for this century."
