摘要
<正>The Greenland ice sheet (GrIS) is the second largest ice sheet in the world, but it is the largest contributor to sea level rise [1] as global warming continues. If its mass was lost completely, global mean sea level would rise by about 7.2 m [2]. Over the recent three decades, mass loss of the GrIS driven by oceanic and atmospheric warming has been significantly increased [3].
