| 摘 要： | 在联合国下属的政府间气候变化专门委员会（IPCC）的4次评估报告影响下，全球变暖达到前所未有家喻户晓的程度．各国人民似乎对“气候变暖”有谈虎色变的感觉．只要是灾难，不论水灾还是旱灾，不管是降温的雪灾还是高温的热浪，各国媒体均将这些灾害与“气候变暖”紧密联系起来，IPCC第四次报告也是如此．气候真的变暖了吗？真的那么严重变暖了吗？气候变暖真的给人类带来的只是可怕灾难而没有益处吗？水灾与旱灾是一对矛盾的2个方面，如何都能够由“全球变暖”一个因素所导致？地质记录表明，气候冷暖波动是地球气候变化一般形式，过去在人类能够影响大气二氧化碳含量以前，地球气候就是一直在不断地冷暖变化着的．驱动地球冷暖变化的主要因素是地球接收太阳辐射量的变化．不变的气候是短期的，是暂时的，而变化的气候却是长期和永恒的．持续了约550年变冷小冰期于1850年结束，随后进入暖期则是正常的自然过程．人类活动最大可能只是叠加了变暖的影响．本研究综合对比分析全球变暖和全球变冷2种气候变化所产生的一系列后果，认为全球变暖给人类带来结果是利大于弊．

| Abstract: | Climate change is a hot topic in modern society, as global warming is detected for last 100 years. Intergovernment Panel on Climate Change （IPCC） believed that human activities played an important role in contribution to global warming. Now people seem afraid very much on the ＂global warming＂, as any natural disasters happen, no matter the disaster is flooding or drought, heat wave or cool snowing disasters, just attribute them as a result of global warming. So did IPCC 4th assess- ment report. Is global climate really warming？ Is global climate really so severely warming？ Does glob- al warming bring to human just disadvantages without any benefits？ Flooding and drought are the two aspects of a pair of antinomy, how both can be caused by the same factor of ＂global warming＂ .9 Geological records show that climatic variation is normal on the earth history. Many glacial and inter- glacial periods, respectively corresponding for global cooling and warming, cycle long time before human appearance. The main driving factor of global change is the amount of the Earth receiving radiation from Sun. Stable climate is temporarily and short terms, while various climate is long terms and everlasting. This paper synthesizes and compares various consequences of global warming and cooling, we think that global warming brings more benefits than disadvantages to human beings. |
