Researchers are talking about a new discovery made recently beneath the Greenland Ice Sheet confirming the persistence of the frozen sheet much longer than their previous estimates.

With the discovery comes another good news, which says that the center of Greenland Island is still stable and global warming effects have yet not started disturbing the region.

The above discovery has come as a big surprise to research experts around the world. According to the studies done by the researchers, the ancient tundra landscape is preserved under the Ice Sheet since past three million years.

"We found organic soil that has been frozen to the bottom of the ice sheet for 2.7 million years," said University of Vermont Geologist Mr. Paul Bierman, Lead Author of the study in the journal Science. "Also the center of Greenland remained stable, it's likely that it did not fully melt at any time," he added.

The testing is still ongoing over the tundra landscape. Total seventeen 'dirty ice' samples have been taken by the researchers from forty feet bottom of the landscape for further research.

The latest information from the experts have confirmed the extraction of a rare form of element beryllium from the collected sediment. Prof Bierman along with a team of researchers at the University of Vermont's Cosmogenic Nuclide Laboratory are working very diligently to find even the smallest amounts of the beryllium in the modern permafrost tundra soil on the North Slope of Alaska.

A few statements have come from Mr. Ben Crosby, a member of the research team from Idaho State University, regarding the newest findings. He has confirmed that the soil on the samples has been found to be stable and they estimate that the surface was exposed to sun somewhere between 200,000 and one million years before it was covered by ice.
