近100多年来,全球平均气温经历了冷－暖－冷－暖两次波动,总体来看为上升趋势.特别是进入八十年代后,全球气温明显上升.1981～1990年全球平均气温比100年前上升了0.48℃ .全球变暖的后果,会使全球降水量重新分配,冰川和冻土消融,海平面上升等,既危害自然生态系统的平衡,更威胁人类的食物供应和居住环境.全球变暖不仅会对地表环境、生态系统等各方个面产生短期或长期的影响,更会对人类文明的繁衍和发展产生深远的影响,甚至威胁着人类的生存.所以,对于全球变暖的研究具有十分重要而深远的意义.目前,全球温度仍在持续上升,每年由于全球变暖造成的气象灾害时有发生,因此,对全球变暖的研究已经到了一个刻不容缓的地步.”Since the industrial revolution, human industrial activities, as well as the dramatic increase in the global population is growing rapidly before the industrial revolution than the Earth's surface temperature has increased by a larger extent. Nearly 100 years, the global average temperature has experienced cold-warm-cold-warm twice fluctuations, the overall view of an upward trend. Especially into the 1980s, the global temperature has gone up significantly. 1981 to 1990 the global average temperature rose by 0.48 ° C over 100 years ago. The consequences of global warming, will redistribute global precipitation, glaciers and permafrost melt, sea level rise, the balance of harm to both natural ecosystems, but also threaten human food supply and the living environment. Global warming will not only surface environment, the ecological systems and other face-to-face short-term or long-term impact the reproduction and development of human civilization, but also have a far-reaching impact, and even threatened the survival of mankind. Therefore, the study of global warming is of great and far-reaching significance. Currently, the continuing rise in global temperature in each of the meteorological disasters caused by global warming is occurring, and thus, Research on global warming has reached a critical state.
