　　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.

　　据英国广播公司报道，电脑模拟显示，到2050年全球气温可比上世纪的水平升高1.4至3.0摄氏度。

　　志愿者的家用电脑上运行了近万个模拟程序。研究人员的目标是探索未来气温更为广泛的可能性，他们表示，这有助于"理解"气候系统诸多的不确定性。

　　这次预测的气温变化比其它模型的预测结果要高一些。

　　变化范围的底端和政府间气候变化专门委员会2007年报告中的结论相似，但是顶端略高于专门委员会分析的结果。
