Global warming could cause the huge Greenland ice sheet
to melt past "tipping points" from which it could not fully recover - even if carbon dioxide levels were slashed, a report has warned.
The midnight sun still gleamed at 1am across the brilliant expanse of the Greenland ice sheet
The possibility that the ongoing rapid demise of Arctic sea ice may instigate abrupt changes on the Greenland Ice Sheet
(GIS) is not tackled by current research.
Experts blamed the record cold ocean temperatures on the melting of the Greenland ice sheet
, also feared to be slowing the Gulf Stream, which pushes warm currents towards Britain.
Dr Rachel Carr, lecturer in physical geography at Newcastle University, said: "Melting of the Greenland ice sheet
will have a significant influence on global sea level rise, so it's vital that we monitor important indicators such as changes in how fast the glacier is moving and the speed with which it is melting, to allow us to understand the mechanisms driving ice loss.
The Greenland ice sheet
, covering 660,000 square miles -- nearly the area of Alaska -- shed an average of 303 gigatons of ice a year over the past decade, according to satellite measurements.
The Greenland Ice Sheet
is an important contributor to global sea levels.
Scientists at Ohio State and Cornell University said last year that two lakes on the Greenland ice sheet
that had previously held billions of gallons of water had mysteriously disappeared.
Washington, June 26 ( ANI ): Researchers suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet
past its stability threshold; resulting in a nearly complete deglaciation of southern Greenland and raising global sea levels some 4-6 meters.
Ice-penetrating radar technology inserted aboard Nasa survey flights has discovered frozen forms of ice blocks at the very bottom of the Greenland ice sheet
which are as tall as city skyscrapers and as wide as the island of Manhattan.
WASHINGTON (CyHAN)- Since the late 1970's, NASA has been monitoring changes in the Greenland Ice Sheet
ISLAMABAD -- British researchers have discovered two subglacial lakes 800 meters below the Greenland ice sheet
