The Global Warming
Li Tianxing Instructor Wu Chaoqun HIS 402 27 May 2013 The Global Warming Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation. Population growth in recent years, the population factor is the rapid increase in global warming, one of the main factors. At the same time, this is a serious danger to the rib natural balance between the ecological environments. So much of the population, each year only to their own carbon dioxide emissions would be a staggering figure, and the results will lead directly to the system of concentration of carbon dioxide in the atmosphere continue to increase, this form of carbon dioxide "greenhouse effect" will have a direct impact on the Earth's surface climate Change. Carbon dioxide and other air pollution that is collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up. Coal-burning power plants are the largest source of carbon dioxide pollution -- they produce 2.5 billion tons every year. Automobiles, the second largest source, create nearly 1.5 billion tons of CO2 annually. Atmospheric pollution factors currently, the increasingly serious environmental pollution has posed a major global problem, but also leads to global warming one of the main factors. Now, with regard to the study of global climate change has been clearly pointed out that since the late 1990s from the Earth’s surface temperature has started to rise. There are numerous causes for this problem. On one hand, human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming according to the theory. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem.
