The eighth ice-shelf collapse on the peninsula in 30 years, it is further evidence of an acceleration in warming.
但是，如果气候变暖发生的范围在比先前观测到的范围更广，这将增加南极大陆大冰架融化的可能性，从而改变世界海平面。
But if warming is occurring across a wider area than previously observed, that could increase the possibility of large ice shelves melting off the continent and changing sea levels around the world.
南极破裂的冰架引发科学家们的警告，他们警告说南极冰的流失可能引起全球海平面上升的灾难性问题。
Disintegrating ice shelves in Antarctica have caused alarm among scientists who warn that ice loss here could mean a disastrous rise in sea levels worldwide.
在2000年，几个巨大的冰山从南极洲的罗斯冰架和朗尼冰架上脱落，现在正漂离南极洲。
