Greenland Ice Sheet:'More than 50 hidden lakes' detected.
As recently as 1 992,it was a relatively small area around the edges of the ice sheet.
The ice sheet which drains into the Amundsen Sea averages about 3 km(1.9 mi) in thickness;
This is undoubtedly the most accurate portrait yet of what lies beneath Antarctica's ice sheet.
This online course highlights how the Greenland ice sheet is monitored from space and the ground.
If the ice sheet melts entirely, the sea levels will be more than 7 m higher and Greenland may become an archipelago.
First off, the game's surface is an ice sheet which is enclosed in a structure known as a rink.
Ice sheet, 260 km2(100 sq mi), broken off of Petermann Glacier in northern Greenland on Aug 5, 2010, considered to be the largest Arctic iceberg since 1962.
So this water here dives down to the bottom of the ice sheet, lifts it up, lubricates it and allows it to move really fast?
If the Greenland ice sheet were to completely melt away, sea level would rise by more than 7 m(23 ft) and Greenland would most likely become an archipelago.
A whopping total of 138 volcanoes are believed to cover the vast West Antarctic Ice Sheet, which straddles the West Antarctic Rift System.
If the Greenland ice sheet were to melt away completely, the world's sea level would rise by more than 7 m(23 ft) and Greenland would most likely become an archipelago.
The study projected a sea level rise of 1.3 m(4.3 ft) from the West Antarctic Ice Sheet if all the sea ice in the Amundsen Sea melted.
On August 1, Greenland's ice sheet lost 12.5 billions tons of ice, more than any day since researchers started recording ice loss in 1950.
The ice is estimated to be about 2,700 meters(9,000 ft) thick at the Pole,so the land surface under the ice sheet is actually near sea level.
On August 1, Greenland's ice sheet lost 12.5 billion tons of ice- more than any day since researchers started recording ice loss in 1950, The Washington Post reported.
Scientist have suggested that the loss of these glaciers would destabilise the entire West Antarctic ice sheet and possibly sections of the East Antarctic Ice Sheet. .
The Ontarian River that was a precursor to Lake Ontario is thought to have drained westward, andthe St. Lawrence drainage to have been created by subsidence due to the weight of the ice sheet.
So far no one has been able to prove if the melt water actually does reach the bedrock and lubricate the ice sheet, or if it simply flows through the ice, never reaching the bottom at all.
Because of global warming, the ice sheet and glaciers are fast melting and the dead bodies that remained buried all these years are now becoming exposed," Ang Tshering Sherpa, former president of Nepal Mountaineering Association.
Made up of layers of compressed snow from over the last 100,000 years,the vast Greenland ice sheet acts as both a valuable record of our past climate and a bellwether for future climate change.
In March 2007, scientists studying the ASE through satellite and airborne surveys announced a significant thinning of the ASE,due to shifts in wind patterns that allow warmer waters to flow beneath the ice sheet.
Satellite data shows the West Antarctic Ice Sheet is also losing mass, and a recent study indicated that East Antarctica, which had displayed no clear warming or cooling trend, may also have started to lose mass in the last few years.
He theorized that the tremendous pressure exerted by the cumulative mass of thousands of vertical meters of ice could increase the temperature at the lowest portions of the ice sheet to the point where the ice would melt.
For 2100, the ice sheet contribution is very likely in the range of 7-178cm but once you add in glaciers and ice caps outside the ice sheets and thermal expansion of the seas, you tip well over two metres,” said the lead author, Jonathan Bamber, of the University of Bristol.
He theorized that the tremendous pressure exerted by the cumulative mass of thousands of vertical meters of ice could decrease the melting point at the lowest portions of the ice sheet to the point where the ice would become liquid water.

These curves for global temperature, atmospheric CO2 and sea level were derived from ocean cores and Antarctic ice cores, from ocean sediments andsnowflakes that piled up year after year over 800,000 years forming a two-mile thick ice sheet.
Russian scientist Peter Kropotkin first proposed the idea of fresh water under Antarctic ice sheets at the endof the 19th century, he theorized that the tremendous pressure exerted by the cumulative mass of thousands of vertical meters of ice could increase the temperature at the lowest portions of the ice sheet to the point where the ice would melt.
