cnn.com — Between 1.5 trillion and 2 trillion tons of ice in Greenland, Antarctica and Alaska have melted at an accelerating rate since 2003, according to NASA scientists, in the latest signs of what they say is global warming. Using new satellite technology that measures changes in mass in mountain glaciers and ice sheets, NASA geophysicist Scott Luthcke concluded that the losses amounted to enough water to fill the Chesapeake Bay 21 times. "The ice tells us in a very real way how the climate is changing," said Luthcke, who will present his findings this week at the American Geophysical Union conference in San Francisco, California.
