Scientists agree that they key player in this scenario is the West Antarctic ice sheet.A Brazil size mass frozen water that as much as 7,000 feet thick,unlike floating ice shelves which have little impact on sea level when they break up,the ice sheet is anchored to bedrock will blow the sea surface.Surrounded by an open ocean,it is also vulnerable.But Antarctic experts disagree strongly on just how unstable it is.Now new evidence reveals that all are most of the West Antarctic ice sheet collapsed at least once during the past 1.3 million years-- a period when global temperatures probabl

科学家们一致同意,在当前情势下,南极西部冰盖（冰原）无疑是首要严峻的问题.一块厚达7000英尺的冰块、体积几乎相当于整个巴西的大小,不同于浮动冰架——崩裂时几乎不会对海平面造成任何影响,当与基岩相连的大冰块分崩离析时,将会撞击覆盖海面的冰原.同时由于冰原的四周都被海洋包围,所以十分脆弱.但是南极专家就其不稳定程度产生了分歧.现在有新的证据证明,在过去的130万年里,南极西部冰盖至少曾经坍塌过一次,并且坍塌极有可能发生在在全球变暖间.
