要关注大气污染带来的长期环境灾难

The Long-termed Environmental Suffering Caused by The Atmospheric Pollution

温室问题是一个十分重要的全球环境问题。它是由于人类活动产生的微量气体污染物进入大气引起的。这类污染物中包括一些二氧化碳和一定量的其它气体(CH_4·N_2O·O_3和CFC)改变了大气中的热比例,从而引起大气温度升高。这种现象通常称为“温室效应”。由于CO_2成倍的累积结果,到下一个世纪的中叶,地球表面的温度将增长1.5℃～4.5℃。这种增温趋势对中国地区来说,应该引起重视。

The greenhouse effect problem is a very important global environmental plo-blem. It is due to that the human activities emit gaseous pollutants into the air. Some of these emissions including carbon doxide and certain other gases (CH4、N2O、O3 and CFC) , altering the heating rates in the atmosphere, and thus causing the bigger temperature in the atmosphere, which is comnonly called 'the Greenhouse Effect' , For the double accumulation effect of CO2, the temperature of atmospbere will increase by 1.5℃-4.5℃ in the middle of next century, This temperature increasing may have significant effects on regional climate of China,
