As Herman Engleheart, a co-author from the California Institute of Technology says, "the West Antarctic ice sheet disappear once and can disappear again."
正如加州理工学院的赫尔曼·恩格尔哈特所说，“南极西部冰盖消失过一次，也可能再次消失。”
Scientists agree that the key player in this scenario is the West Antarctic ice sheet, a Brazil-size mass of frozen water that is as much as 7000 feet thick.
科学家们一致认为，这一情境中的关键推手是南极西部的冰层，这是一块跟巴西（面积）差不多大小的冰原，厚达7000英尺。
Pine Island glacier(PIG) is one of many at the fringes of the West Antarctic ice sheet.
派恩岛冰川（PIG）位西部南极冰原边缘力的冰山之一。
There is 10 feet of sea level rise stored up in the unstable part of the West Antarctic ice sheet.
西南极冰架的不稳定部分一旦融化，会让海平面上升10英尺。
Among the fastest moving glaciers in Antarctica, Pine Island drains about 79 cubic kilometers (19 cubic miles) of ice per year from the West Antarctic ice Sheet.
在南极快速移动的冰川里，来自南极西部冰盖的松岛的冰面每年缩小约79立方公里。
As a primary outlet for the West Antarctic Ice Sheet, the Pine Island Glacier is one of the largest sources of uncertainty in global sea level rise projections.
作为南极西部冰盖的基本出口，松岛冰川全球海平面上升预测中最大的不确定性之一。
Presently, most research is concentrated on the coastal ice shelves of WAIS (West Antarctic ice Sheet), very few work has been done for in-land glaciers in East Antarctica.
目前的研究重点主要在西南极沿岸冰架地区，东南极内陆冰盖地区涉足很少。
However, the instability of West Antarctic Ice Sheet will increase with the climatic worming and thus will become the most important in the factors causing the sea level rise.
但是西南极冰盖的不稳定性可能随气候持续变暖而增强，成为引起海平面上升的最重要潜在因素。
If coastal ice shelves buttressing the west Antarctic ice sheet continue to disintegrate, the sheet could disgorge into the ocean, raising sea levels by several metres in a century.
假如支撑西南极洲冰盖的沿岸冰架持续解体，那么冰盖就会泄入海洋，百年之内海平面便将上升数米。
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。
