The discovery helps scientists better understand the mechanism of drainage under the ice layer, affecting the effects of global warming.
American geologists say they have discovered an intact station from the pre-glacial period that was preserved for 2.7 million years underneath the ice sheet on Greenland.
Global sea levels are rising at an unusual rate as the Greenland ice sheet begins to melt after a sustained effort.
Researchers have discovered for the first time lakes located beneath ice shelves in Greenland, the world's largest island.
Dr. Marco Tedesco, associate professor of Earth and Atmospheric Science at New York City College, and a colleague have studied the impact of climate change on the face of Greenland
