地球气温在2100年前将继续上升


The Earth will become a much hotter place over the next century, according to researchers who predict in a study, there is a 90 percent chance the planet''s average temperatures will rise 3 to 9 degrees Fahrenheit by 2100.


Researchers at the National Center for Atmospheric Research used a computer model to predict probable long-term increases in the Earth''''s temperature if no actions are taken to curb the emissions of gases and pollutants that many scientists blame for global warming.


The researchers said the planet has warmed up by about 1 degrees over the last century. But they say it is likely to heat up by about 1 or 2 degrees as early as 2030.By 2100, the most likely increase would be in the range of 4 to 7 degrees, they said.


美国国家大气研究中心的研究人员在一项研究报告中预测说，地球在未来的一个世纪内将变得更热，气温从现在到2100年为止将平均上升华氏3-9度(约为2-6摄氏度)。这一预测成为现实的可能性为90%。


研究人员的这一结论是用一个固有的电脑程式计算出来的。研究人员表示，在过去的一个世纪内，地球气温升高了大约一华氏度(约为0.667摄氏度)，在2030年之前还会升高1-2华氏度；在此基础上，到2100年前，气温还会上升4-7华氏度。
