Greenland Ice Melting Faster

"The ice sheet sitting atop Greenland is the world's largest storehouse of ice outside Antarctica, and the coldest region of the Northern Hemisphere, but even it appears to be under duress from global warming.Although the vast ice cap has been melting in fits and starts since the end of the last glaciation, researchers using satellite data and other observations have made an alarming discovery: The rate at which it is shrinking has suddenly begun to accelerate."

"Greenland's disappearing ice is making a measurable contribution to rising sea levels..Many scientists expect sea levels will rise by about half a metre over the next century, due mainly to the melting of ice and the expansion of water as its temperature rises due to global warming."
