Ice Mass Changes
Current international focus on global warming issues has drawn attention to the melting of the polar ice caps. An early analysis of GRACE-based studies data indicated that the EAIS was losing mass at a rate of 57 billion tonnes per year and that the total Antarctic ice sheet (including WAIS, and EAIS coastal areas) was losing mass at a rate of 152 cubic kilometers (ca 139 billion tonnes) per year. More recent estimate published in November 2012 and based on the GRACE data as well as on an improved glacial isostatic adjustment model indicates that the East Antarctica actually gained mass from 2002 to 2010 at a rate of 60 ± 13 Gt/y.

Famous quotes containing the words ice and/or mass:
“Every incident connected with the breaking up of the rivers and ponds and the settling of the weather is particularly interesting to us who live in a climate of so great extremes. When the warmer days come, they who dwell near the river hear the ice crack at night with a startling whoop as loud as artillery, as if its icy fetters were rent from end to end, and within a few days see it rapidly going out. So the alligator comes out of the mud with quakings of the earth.”
—Henry David Thoreau (1817–1862)
“Teach those Asians mass production?
Teach your grandmother egg suction.”
—Robert Frost (1874–1963)
