Nowadays, one of the most difficult problems is Global Warming. It is obvious that increasing in earth's temperature has made significant negative effects on earth's climate during the last few decades. Not only earth's climate was affected, but also the world's life was involved by this changing. While most people do not realize the worse effects of rising the earth's temperature, the researchers try to illustrate the impact of changing the earth's temperature on the future of the next generations on this plant(1). Clearly, people could notice that earth's weather has varied several times during the last few decades(1). Because of the effects of Global Warming, winter season become warmer and warmer. These effects lead to many modifications on earth's climate. In our days, the researchers are working hardly to go ahead in their studies' and obtain the reasons and the impacts of Global Warming and discover the best solution for this dilemma. Consequently, researchers' studies figure out that Global Warming comes from many sources, especially human's activities and the natural factors. Both are responsible for increasing the figure of Carbon dioxide (Co2) and other gases in earth's atmosphere. It is important that the governments and people find solution for Global Warming problem and decrease the buildings and greenhouses emission, cut down the industrial waste heat, and encourage people to use biofuel in their vehicles.
The researchers may able to find out the three main sources of Global Warming: human's activities (that is caused by their daily activities and its impacts on people's life) and the natural factors (which is caused by the chemical and physical impacts of natural sources) (3). To be precise, there are two kinds of human's sources such as heat and gases emission that produce from the buildings and the greenhouses and heat loses that come from the power plants and factories. The buildings and greenhouses emissions are heat and gases emit from any buildings and houses activities like air-conditioning, using gas for houses and buildings activities, the radiations that come from the electrical equipment. All these reasons have largely impact on earth's weather due to increasing the proportion of Carbon dioxide (Co2). Many researchers may argue that the building and the greenhouses emissions get the great benefits to earth's weather and environment because they believe that these emissions...
