If it continues, Greenland itself could become much smaller during this century and global seas could rise as much as 3 feet.The rates of change that were noticing are much higher than expected. If these rates continue, it is not unlikely that Greenland could shrink by several tens of percent this century. However, its not known how quickly this coastal response of the Greenland ice sheet melting will have an effect on the vast inland ice.Greenland is the worlds largest island, covering an area more than three times the size of Texas. Some 81 percent of it is covered by ice, and there are many glaciers. Glaciers are like slow-moving rivers of ice. Where a glacier meets the sea, its weight keeps it firmly resting on the bottom. A glaciers front is the point where the water is deep enough that the glacier floats.Since the 1970s, the front of Helheim stayed in the same place. Then it began melting rapidly, moving back 4.5 miles from 2001 through this past summer. It has also grown thinner, from top to bottom, by more than 130 feet since 2001. And over these past four years, its trip to the sea has sped up from about 70 feet per day to nearly 110.The melting is driven by a warmer climate. Temperatures in Greenland have risen more than five degrees Fahrenheit in the last decade. Since most of Greenlands ice is on land, seas will rise as the ice melts. If all Greenlands ice sheet melted, oceans would be 15-20
