全球变暖的原因很多，概括以后有以下几点：
1.人口剧增因素
近年来人口的剧增是导致全球变暖的主要因素之一。同时，这也严重地危肋着自然生态环境间的平衡。这样多的人口，每年仅自身排放的二氧化碳就将是一惊人的数字，其结果就将直接导制大气中二氧化碳的含量不断地增加，这样形成的二氧化碳“温室效应”将直接影响着地球表面气候变化。
2.大气环境污染因素
目前，环境污染的日趋严重已构成一全球性重大问题，同时也是导致全球变暖的主要因素之一。现在，关于全球气候变化的研究已经明确指出了自上个世纪末起地球表面的温度就已经开始上升。
3.土地遭侵蚀、沙化等破坏因素
4.森林资源锐减因素
在世界范围内，由于受自然或人为的因素而造成森林面积正在大幅度地锐减。

there Are many reasons for global warming, summed up the future include the following:
1. Population explosion factor
In recent years, the rapid increase in population led to one of the main factors of global warming. At the same time, it is also a serious danger ribs with a balance between the natural ecological environment. So many people, only its own emissions of carbon dioxide per year would be a staggering figure, the result will lead directly to the content system of atmospheric carbon dioxide is increasing, so the formation of carbon dioxide "greenhouse effect" will directly affect the Earth's surface climate change.
2. Atmospheric pollution factors
At present, the worsening of environmental pollution has posed a major global problem, but also contribute to global warming, one of the main factors. Now, with regard to global climate change research has clearly pointed out that since the beginning of last century the Earth's surf
