As the summer melt season reaches its peak, the largest Arctic ice shelf has jettisoned a piece of ice twice the size of Manhattan. The Geological Survey of Denmark and Greenland reported on Monday that the Northeast Greenland Ice Stream has lost more than 19 square miles (50 square kilometers) for the second year in a row. When those structures weaken and disintegrate, as the Northeast Greenland Ice Stream has now done, glacier movement picks up. A major break in an ice stream that drains 16% of Greenland’s inland ice is only the newest symptom of the Arctic’s new climate. “We should be very concerned," said Jason Box, another research professor at the Geological Survey of Denmark and Greenland.
