Accelerated Antarctic ice loss from satellite gravity measurements

Accurate quantification of Antarctic ice-sheet mass balance and its contribution to global sea-level rise remains challenging. Gravity Recovery and Climate Experiment data spanning the period April 2002 to January 2009 confirm earlier estimates of ice loss for Antarctica and indicate that East Antarctica started losing mass in about 2006.
