Scientists say sea levels may rise faster than previously thought as they gain new insights about the rate at which the Greenland Ice Sheet melts into the sea. In two new studies, researchers found that the mechanics involved in ice loss are more complex than what current models account for. Ben Gruber reports.
STORY: Sea levels may be rising faster than previously thought - that's according to two new studies focused on the Greenland Ice Sheet. Using data provided by NASA that tracks changes in the massive ice sheet, scientists have been able to create the most detailed picture ever of how the ice sheet moves toward the sea....as well as gain a better understanding of how water is flowing under its surface. Current models of Greenland's ice loss use the activity of four well-studied glaciers to forecast how the entire ice sheet will dump ice into the ocean. That approach, according to the new studies, is too simplistic and doesn't take into account all of the factors associated with the ice melting. Scientists say that if the entire ice sheet melted, global sea levels would rise more than seven metres, devastating coastal communities around the world. Researchers now plan tracking all 242 glaciers in Greenland, as well as water underneath the ice to develop more accurate models going forward.
