Global+Warming+Theories

Global Warming Theories There are many theories about why global warming has been so tremedous in the past century. Only a few of them are listed below:
 * Global warming is caused by the pollution caused by people. This is what many people are known to believe. The pollution amounts and carbon footprint of the people of the world is soooo humungous that this theory is not unreasonable. If global warming is caused by the people of the world, then the only way to stop global warming is to reduce the pollution and carbon footprint of the world.
 * Global warming is caused by a hot spot. In many times in the world's history, the earth's temperature has undergone series temperature rises and drops. This may just be another temperature rise like some of the times in the past. However, if this is the reason for global warming, it cannot be stopped for the time being and the temperature will hopefully rebound like it has in the past.
