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:
“Will lovely, lively, virginal today
Shatter for us with a wing’s drunken blow
This hard, forgotten lake haunted in snow
By the sheer ice of flocks not flown away!”
—Stéphane Mallarmé (1842–1898)
“I am not a very sentimental man; and the best sentiment I can think of is, that if you collect the signatures of all persons who are no less distinguished than I, you will have a very undistinguishing mass of names.”
—Abraham Lincoln (1809–1865)
