Give yourself the gift of knowledge with a subscription to Big Think Edge. http://bit.ly/bigthinkedge There are ancient secrets and and clues to the future trapped in Greenland's ice. - The Greenland ice sheet covers 80% of the island of Greenland. The sheet is 1,500 miles long, 700 miles across, and two miles thick. Scientists call it the largest laboratory in the world. - By studying the minerals and gasses trapped in layers of ice, glaciologists can unravel mysteries of the past, such as what the temperature was 1,000 years ago, or search for clues as to why the Greenland Norse people vanished. - Ice cores are a key to the past that also unlocks the future. Studying Greenland's ice sheet is yielding valuable information about the future of climate change.

Give yourself the gift of knowledge — subscribe to Big Think Edge: http://bit.ly/bigthinkedge The more Greenland melts, the more Greenland melts. Here's why. - The Arctic is currently warming about twice as fast as the rest of the world. - Ice is white and bright and is able to reflect solar energy back into space. When it melts and exposes dark, open ocean, that open ocean absorbs more sunlight and more energy. This creates a kind of feedback loop. - The darkness absorbs more solar energy — more sunlight. In turn, this accelerates the melt of the ice. Jon Gertner is a journalist and historian whose stories on science, technology, and nature have appeared in a host of national magazines.
