According to reports, a chunk of ice four times size of Manhattan has broken off Pine Island Glacier in Antarctica. Scientists, who first noticed a large rift in Pine Island's center last March, say that since the ice chunk was part of a glacier, it will not raise sea levels.
據報道，南極洲派恩島冰川上脫落了一塊和曼哈頓四倍大的冰塊。在去年三月首先意識到派恩島中心有一個大裂縫的科學家說，因為這個大冰塊是冰川的一部分，所以它不會導致海平面上升。
However scientists add that the glacier is melting differently from other parts of Antarctica - forming cracks in its center under the ice instead of breaking apart from the sides. This unusual behavior is said to be due to warmer ocean waters and could expose ice on Antarctica that will raise sea levels if the pattern continues.
但是，科學家說這里的冰川融化和南極洲的其他地方不一樣——它是在冰下的中心形成裂縫，而不是從邊緣脫落。據說這種奇怪的現象是因為海水溫度升高，如果繼續這樣下去，將會使南極洲上的冰面暴露，導致海平面上升。
