Using satellite radar interferometry observations of Greenland, we detected widespread glacier acceleration below 66 degrees north between 1996 and 2000, which rapidly expanded to 70 degrees north in 2005. Accelerated ice discharge in the west and particularly in the east doubled the ice sheet mass deficit in the last decade from 90 to 220 cubic kilometers per year. As more glaciers accelerate farther north, the contribution of Greenland to sea-level rise will continue to increase.
利用对格陵兰岛的卫星雷达干涉测量观测数据，我们发现在1996年至2000年期间，北纬66度以南的冰川普遍加速，到2005年迅速扩展到北纬70度。在过去十年中，西部尤其是东部加速的冰排放使冰盖质量亏损增加了一倍，从每年90立方千米增至220立方千米。随着更多冰川在更北的地区加速，格陵兰岛对海平面上升的贡献将持续增加。
