No one quite knows why glaciers and ice shelves are melting so fast, or how a meltwater lake on the Greenland ice sheet covering six square kilometres could drain away in 24 hours, as it did in 2006.
没有人非常了解为什么冰架这么迅速的融化，也没人知道格林兰冰架上的一个覆盖6平方千米的融水湖会在24小时内流干——这在2006确实发生了。
Our theory links an external climate-driven process, the melting of the ice sheet, and earthquakes.
我们的理论将外部气候驱动过程，冰盖融化与地震联系起来。
One of the possible mechanisms which we think may have triggered these changes is melting driven by changing ocean temperatures and currents at the margins of the ice sheet.
我们认为，可能引发这些变化的一个原理是海洋的气温变化和冰盖边缘的潮流导致冰融化。
Whether acceleration of melting from the Greenland Ice Sheet will continue, he added, is a big question mark.
他补充道，格林兰冰盖是否会继续加速融化还是一个大问号。
It would take the melting of an ice sheet to do that.
但是，一个大冰原的融化就不同了。
9/17The year saw a flood of scientific papers showing Arctic ice and the Greenland ice sheet is melting faster than ever, leading to a race for the new riches of the Arctic.
9/17 这一年，大量的科学论文阐述了北极冰层和格陵兰冰雪融化的速度比以往任何时候的快，创造了北极融化英尺数新高。
The melting has been recorded since 1979; scientists put the annual net loss of ice and water from the ice sheet at 300-400 gigatonnes, which could hasten a sea level rise of catastrophic proportions.
自1979年以来，融冰已经记录在案；科学家们估计每年冰的净损失以及冰盖融水达300-400千兆吨，这有可能促使海平面上升、足以引发灾难。
The strait’s status in turn affected ocean currents, which affected the rate of ice sheet melting during the last glacial period.
在上次冰河时代，白令海峡这种周期性的开闭，影响了洋流，进而影响冰盖融化的速度。
The melting of Greenland's ice sheet is accelerating, threatening an increasing rise in sea levels.
格陵兰岛冰层的融化速度正在加快，可能导致海平面加速上升。
It is not simply that the ice sheet is melting steadily as global temperatures rise.
这并不仅仅是说随着全球气温升高，冰盖在稳步融化。
Chen said that warmer ocean waters may have triggered the melting by seeping under the ice sheet and making it slide more easily over the rock it rests on.
陈建力指出，海水变暖可能导致海水渗入冰盖下面，使冰盖上部更容易失去支撑而滑入水域，从而引发冰盖的消融。
The survey confirmed the West Antarctic ice sheet is melting rapidly with the loss of around 132bn tonnes of ice a year, but revealed unexpected melting in the larger East Antarctic ice sheet.
这项调查证实，南极西部冰盖正以每年约1320亿吨的速度迅速融化，但同时也显示，面积更大的南极东部冰盖正出乎意料地逐渐消融。
