温室效应和温室气体减排分析

人类活动所排放的温室气体在大气层中的不断增加和积累，使地球温室效应变得越来越严重。由于温室气体所造成的气候异常和由此引发的灾害无国界，因此解决温室气体排放是全人类共同的问题。为此，介绍了温室气体和温室效应，以及大气层中CO2浓度变化和世界排放CO2的情况；通过分析说明世界经济高速发展对化石燃料需求的不断增长，是第二次世界大战以来尤其是近20年来大气中CO2浓度快速增长的主要原因。同时还对排放CO2最多的发电和供热、交通运输、房屋建筑3大领域的节能和减排进行了分析，指出解决全球变暖问题需要人类的智慧、良知和理智。

Greenhouse Effect and Emission Reduction of Greenhouse Gases

Globally,a greenhouse effect becomes more and more serious because of a continuous increase and accumulation of greenhouse gas caused by people activities.Greenhouse gas brings about an abnormal climate and even will cause some hazards.So far,how to reduce greenhouse-gas emission is an important problem for human being.This paper presents both greenhouse gas and greenhouse effect;meanwhile,it illustrates CO2 concentrationvariation in atmosphere and CO2emission in the world.It is indicated that the main caus...
