Causes of Global Warming.

Most of things in our world have causes on the environment. In the following I am going to look at the various reasons that have led to this development. The first point worth mentioning is Carbon Dioxide Emitted from transportations such as cars, trucks, airplanes, about 36.5% of U.S carbon dioxide emissions comes from the burning of gasoline. Another 40% of U.S. comes from the burning of fossil fuels for the purpose of electricity generation. Second most important cause is greenhouse gases such as water vapor, carbon dioxide and methane, these gases heats the surface and lower atmosphere, which emits some energy back to earth. Another major cause of global warming is population, normally every year the number of population rise which means more method of transportation will used which cause more methane, carbon dioxide will spread in the weather, as well its will going to help cause global warming.
