NASA has said that the Antarctic has shrunk by about 152 cubic kilometers annually from April 2002 to August 2005 raising the sea water level by 1.2 millimeters. The research conducted at the University of Colorado at Boulder used data from the NASA/German Aerospace Centre Gravity Recovery and Climate Experiment (GRACE) said that Antarctic was the largest reservoir of water and this loss is equivalent to the amount used by the US in 3 months.
