温室气体与气候变迁——兼论科学不确定性

GREENHOUSE GASES AND CLIMATE CHANGE UNCERTAINTIES IN SCIENCE

Rising global tempreture resulted from increasing carbon dioxide and other greehouse gases in the atomosphere is causing an increasing worldwide concern and the pressure change is rapidly escalating.This paper reviewed various viewpoints in scientific researches on carbon dioxide with its sources and sinks, warning effects and impacts,etc,and showed different understanding of acting mechanisms of other greenhouse gases.The scientific uncertainties on greenhouse gases and climate change resulted in an obstacle to effective progress in international policy-making for global environment conservation, and the necessity to solve the problem of uncertainties have being become an urgent task to scientists.The conception of integration of environmental protection and economic development is highly appreciated.
