12/25/2008
According to NASA's Gravity Recovery and Climate Experiment (G.R.A.C.E.), between 1.5 trillion and 2 trillion tons of ice has melted in Alaska, Greenland and Antarctica since 2003. The G.R.A.C.E. project uses 2 satellites to measure changes in glaciers and ice sheets and NASA scientists will present their findings at the American Geophysical Union conference as further proof of global warming.
