Many glaciers are melting alarmingly fast. A computer simulation has suggested that global temperatures could rise by1.4-3.0C above levels for late last century by 2050, the BBC reported.

　　A computer simulation has suggested that global temperatures could rise by 1.4-3.0C above levels for late last century by 2050, the BBC reported.

　　Almost 10,000 climate simulations were run on volunteers' home computers. The researchers aimed to explore a wider range of possible futures, which they say helps "get a handle" on the uncertainties of the climate system.

　　The projections are somewhat higher than those from other models.

　　The low end of their range is similar to that of the Intergovernmental Panel on Climate Change in its 2007 report, but the high end is somewhat above the range their analysis produced.

　　據英國廣播公司報道，電腦模擬顯示，到2050年全球氣溫可比上世紀的水平升高1.4至3.0攝氏度。

　　志願者的家用電腦上運行了近萬個模擬程序。研究人員的目標是探索未來氣溫更為廣泛的可能性，他們表示，這有助於"理解"氣候系統諸多的不確定性。

　　這次預測的氣溫變化比其它模型的預測結果要高一些。

　　變化範圍的底端和政府間氣候變化專門委員會2007年報告中的結論相似，但是頂端略高於專門委員會分析的結果。
