地球气候变化及其主要原因

摘要

地球上的气候自始至终都在不停地变化.冷暖交替,气温波动,是气候变化的最基本特征.自然因素是地球气候变化的主要原因,而人类活动不是气候变化的主要原因,人类活动排放的二氧化碳更不是气候变化的罪魁祸首.地球上的气候灾害主要是自然因素引起的,而人为因素的影响是很小的.减排二氧化碳既不能阻止气候变化,也不能预防气候灾害的发生.大规模地减排二氧化碳,劳民伤财,徒劳无益,势必扰乱社会经济的健康发展.%The climate on the earth,from time to time,has been changing without stop.Replace of both the cold and warm,and fluctuation of air temperature,are the most basic property of climate change.Natural factors are main causes led to climate change,and but so are not anthropogenic activities,and still more the carbon dioxide emitted by anthropogenic activities is not chief culprit of climate change.Disasters of climate on the earth mainly are produced by natural factors,and influence of anthropogenic factors is very small.Decrease of emission of carbon dioxide cannot stop climate change,and cannot prevent happening of climate disasters,too.Large-scale decrease of emission of carbon dioxide would disturb healthy development of the society and economy.
