气候变化格陵兰和南极这两大冰原最近受到了大量的压力，冰川奔腾，整个融水湖在几分钟内就坠入冰洞。通过飞机和卫星对冰盖体积的调查已经量化了这些损失，但这些评估在时间、空间或两者上都是参差不齐的。从20世纪90年代到21世纪初，萎缩加速，但研究人员无法确定接下来会发生什么。现在，对冰盖进行的最全面、基本上是连续监测的最新分析显示，过去几年中，损失并没有减轻。
Climate ChangeThe two great ice sheets—Greenland's and Antarctica's—have had plenty of press lately, what with galloping glaciers and whole lakes of meltwater plunging into ice holes in minutes. Surveys of ice-sheet volume made from planes and satellites have quantified these losses, but those assessments have been spotty in time, space, or both. Shrinkage accelerated from the 1990s into the 2000s, but researchers couldn't be sure what would come next. Now the latest analysis of the most comprehensive, essentially continuous monitoring of the ice sheets shows that the losses have not eased in the past few years.
