According to a new study by scientists at the University of Texas, the East Antarctic ice sheet, once thought to be unaffected by global warming, is melting fast.  Estimates using satellite observations place ice loss in the East Antarctic at 5 to 109 gigatons per year from April 2002 to January 2009.  But, estimates also suggest that the rate of melt sped up after 2006.  This loss is seen most in coastal regions such as Wilkes Land and Victoria Land.  Previous estimates of the East Antarctic ice sheets ranged between a 4 gigaton per year loss and a 22 gigaton per year gain.
