A Chinese scientist predicted in Beijing Monday that the global temperature will rise 1.4 to 5.8 degrees centigrade in the coming 100 years, marking the fastest temperature ascending period in recent 10,000 years.

Addressing a conference held in Beijing, Qin Dahe, the academician with Chinese Academy of Sciences and also the director of China Meteorological Administration, said that the surface temperature over the earth climbed 0.6 degrees centigrade on the average in the past 150 years, however, rose faster during the recent 20 years due to the effects intensified by human activities.

 

Scientists think that the increase of carbon dioxide density in the air could be the indicator to temperature growth. At present, the world annual carbon discharge amounts 6.3 billion tons, and expected to reach 35 billion tons in 2100.

 

Scientists warned that global warming will affect ecological system, social economy and national security, and possibly induce the deficiency of cultivated land, resources and energy resources, and may cause regional friction or even wars.
