Global warming is in a period of time, the earth's atmosphere and ocean temperatures phenomenon, is mainly refers to man-made temperature to rise. Think may be e to the worldwide greenhouse gas (co2) emissions caused by too much.Nearly 100 years, the average global temperature has experienced: cold and warm to cold, warm, four on the whole the temperature to rise. After entering the eighty s, global temperature rise significantly.The global atmosphere and the surface of this system is like a huge "glass greenhouse", make the earth's surface has always maintained a certain temperature, the suitable for humans and other biological survival environment. In this system, can not only let the sun radiation through the atmosphere and reach the ground, and also can prevent the ground radiation loss, we put the atmosphere on the surface of this protective effect is called the atmospheric greenhouse effect (green house effect). Known as the greenhouse gases "greenhouse gases", they can make the sun shortwave radiation through freedom, at the same time can absorb long-wave radiation from the earth's surface. These gases have a carbon dioxide, methane and chlorofluorocarbons, ozone, nitrogen oxide and water vapor, etc., is one of the main carbon dioxide. Over the past century global climate is graally warming, at the same time, the content of greenhouse gases in the atmosphere are also increased dramatically. Many scientists agree that greenhouse gas emissions of the greenhouse effect caused by the fuel is the basic cause of global warming. 全球变暖指的是在一段时间中，地球大气和海洋温度上升的现象，主要是指人为因素造成的温度上升。世界范围内认为可能是由于温室气体（二氧化碳）排放过多所造成的。　　近100多年来，全球平均气温经历了：冷→暖→冷→暖四次波动，总的来看气温为上升趋势。进入八十年代后，全球气温明显上升。　　全球大气层和地表这一系统就如同一个巨大的"玻璃温室"，使地表始终维持着一定的温度，产生了适于人类和其他生物生存的环境。在这一系统中，大气既能让太阳辐射透过而达到地面，同时又能阻止地面辐射的散失，我们把大气对地面的这种保护作用称为大气的温室效应（green house effect）。造成温室效应的气体称为"温室气体"，它们可以让太阳短波辐射自由通过，同时又能吸收地表发出的长波辐射。这些气体有二氧化碳、甲烷、氯氟化碳、臭氧、氮的氧化物和水蒸气等，其中最主要的是二氧化碳。近百年来全球的气候正在逐渐变暖，与此同时，大气中的温室气体的含量也在急剧增加。许多科学家都认为，温室气体的大量排放所造成的温室效应的加剧是全球变暖的基本原因。
