2050年世界变成这样：全球变暖(组图)

全球气候变暖明显

　　Global Warming 全球变暖

　　A recent research report published by the United Nations indicates that it is quite possible that the Earth's temperature is rising well above the previous estimate.

　　最近由联合国公布的研究报告指出，地球温度的上升很可能远高于以前的估计。

　　Such an outcome would have severe consequences, such as the collapse of the Greenland ice sheet and disruption of the Gulf Stream ocean current.

　　这样的结果会造成严重后果，例如格陵兰冰层崩塌以及

　　The Antarctic ice sheet, which contains 90% of the world's ice, has lost significant mass in the past few years. The discovery comes as a surprise to scientists, who thought that the continent would gain ice this century because of increased snowfall in a warming climate.

　　占有全世界冰川总量90%的南极洲冰层主体在过去几年里显著萎缩。对于科学家们来说，这个发现出乎意料，因为他们曾经认为温暖的气候会带来更多降雪，从而在本世纪增加南极洲的总冰量。

　　A research team from the University of Colorado used satellite data to estimate that the ice sheet will lose up to 48 cubic miles by 2050. In comparison, a city the size of Los Angeles uses one cubic mile of fresh water every year. Ice shelves in the Antarctic will have decreased by more than 7,200 square miles in the next four decades.

　　科罗拉多州大学的研究小组利用卫星资料进行预测，到2050年(南极洲)冰层将会丧失多达48立方英里的冰量。与之相对的是，洛杉矶这样规模的大城市一年消耗的淡水总量也不过1立方英里。在未来40年里，南极洲冰架将缩减7200多平方英里。

　　At twice the size of Australia, Antarctica is the Earth's fifth largest continent and contains 70% of its total fresh water resources.

　　南极洲是地球第五大洲，面积是澳大利亚的两倍，拥有全球淡水资源的70%。
