NASA | Glacial Ice Loss: Greenland and Antarctica

In the first comprehensive satellite study of its kind, a University of
Colorado Boulder-led team used NASA data to calculate how much Earth's
melting land ice is adding to global sea level rise. This animation shows
the average yearly change in mass, as measured by the NASA/German Aerospace
Center Gravity Recovery And Climate Experiment (GRACE) satellite mission.
The animation shows ice loss over Greenland and Antarctica, as measured in
centimeters of water from 2003 to 2010. These two landmasses are covered
with the largest land-based ice sheets in the world, and are the key sources
of scientists' concern about future sea-level rise. Regions with large ice
loss rates are denoted with the blue and purple colors. There are enormous
ice loss rates over substantial regions of both ice sheets. A colorbar shows
the range of values displayed.
