Scientists Uncover ‘Contributor’ to Greenland Sea Level Rise

Greenland is a big island -- about the size of Saudi Arabia -- covered by ice and snow. But climate experts agree that frozen ground cover is melting at an accelerating pace, raising the sea level. If it were to melt completely, global sea levels would rise more than seven meters. As VOA’s Rosanne Skirble reports, a new study examines how Greenland's vast network of little-understood rivers and streams is carrying water seaward.
