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 begins
with yellow dots showing the study's global inventory of individual
glaciers, as measured by the NASA/German Aerospace Center Gravity Recovery
And Climate Experiment (GRACE) satellite mission. The animation then fades
to show the average yearly change in mass, as measured in centimeters of
water from 2003 to 2010 from all of the worlds glaciers and ice caps
(excluding Greenland and Antarctica). This is essentially a measure of how
much ice the world's glaciers are losing, and in some cases gaining. Regions
with large ice loss rages stand out clearly as blue and purple. A colorbar
overlay shows the range of values displayed.
