Greenland and Antarctica ice sheets

Grace Satellite shows ice loss in East Antarctica

New York, November 23 -- According to a recent study by scientists at the University of Texas, East Antarctica’s ice has started melting at a faster rate since 2006 which could do some serious destruction to the sea level.

Climatic changes making ice shelves disappear

Washington, April 5: Global warming is slowly and steadily taking its toll on our planet. According to the latest reports pouring in from the U.S. and British government researchers, one of the Antarctic ice shelves has disappeared and another is on the verge of vanishing.

Scientist ponders ice sheet melting

Chicago -- A U.S. geoscientist says although it's known the Greenland and Antarctica ice sheets are melting, how much ice will melt is undetermined.

Penn State Professor Richard Alley said if Greenland's ice sheet melts, sea level will rise about 23 feet, which will inundate portions of nearly all continental shores. However, Antarctica, containing much more water, could add another 190 feet to sea level.

"We do not think that we will lose all, or even most, of Antarctica's ice sheet," said Alley. "But important losses may have already started and could raise sea level as much or more than melting of Greenland's ice over hundreds or thousands of years,"

Alley said those who study ice sheets have long modeled ice sheet behavior but simulations of the whole Earth system typically haven't included ice sheets along with the atmosphere, oceans and clouds. He said past atmospheric modelers usually treated the ice sheets simply as white mountains.
