「This study showing warming means we can「t be complacent about thinking the West Antarctica ice sheet is invulnerable,」 Steig said.

「这项研究显示，气候变暖意味着我们不能自满，不能认为南极西部冰原不会遭到破坏而洋洋自得，」史代格说。

Several rivers of the West Antarctica ice sheet flow into the ice shelf.

南极洲西部几条河流中的冰块漂流到冰架。

East Antarctica is colder than West Antarctica because of its higher elevation.

南极洲东部由于海拔较高，比南极洲西部寒冷。

Researchers estimate that the accelerating flow of glaciers in West Antarctica is contributing about 10% of the observed rise in the mean global sea level.

研究人员估计，西南极洲冰川的加速流动在已观测到全球平均海平面上升中所起的作用约占10％。

The B9 iceberg broke from the Ross Ice Shelf in West Antarctica some time in 1987.

Antarctica is the world」s biggest source of land ice after Greenland, but — with the exception of West Antarctica — is considered more resistant to any doomsday collapse.

南极洲是仅次格陵兰世界上最大的陆地冰源地，但是-除南极洲西部外-仍被认为是最能抵御世界末日崩溃的凈土。

Ice is melting worldwide, especially at the Earth's poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and arctic sea ice.

冰正在在全球溶化，特别是地球两极，包括高山冰川，复盖着西南极洲和格林兰的大冰源，和北极的冰海。

Similarly, at the other end of the planet, near the South Pole, scientists have found new evidence of snow melting in West Antarctica across an area as large as California.

与此相似，在地球的另一端南极，科学家们也已发现新的证据：南极洲西部一块和加利福利亚面积差不多大的冰雪正在融化。
