"NASA-supported researchers have found that ice covering Greenland is melting faster than previously thought. The action is happening out of sight, below the surface."
Why should you care? NASA:
More than 90 percent of our planet's freshwater ice is bound in the massive ice sheets and glaciers of the Antarctic and Greenland. As temperatures around the world slowly climb, melt waters from these vast stores of ice add to rising sea levels. All by itself, Greenland could bump sea levels by 7 meters (23 feet) if its ice melted completely.
