Burning of fossil fuels for the purpose of electricity generation is the main cause of global warming. About 93% of the carbon dioxide is emitted from the electric utility industry. Coal emits about 1.7 times as much carbon as natural gas. Natural gas gives out 50% carbon dioxide. Carbon dioxide is emitted from cars too; about 20% of carbon dioxide comes from the burning of gasoline in the internal combustion engines of cars and other kind of vehicles. Carbon dioxide is emitted from airplanes and it causes about 3.5 % of global warming and it will rise as years pass by. Methane is also one of the major gases which contribute to global warming. While carbon dioxide is the principal greenhouse gas, methane is second most important. It is twenty times more effective than carbon dioxide in trapping the heat in the atmosphere. Another greenhouse gas is nitrous oxide; it is a colorless non-flammable gas with a sweet smell. It is produced naturally in oceans and rain forests. Some examples of manmade nitrous oxides are nylon nitric acid and fertilizers. Deforestation is also another main cause of atmospheric carbon dioxide. The destroying of forests is throwing hundreds of millions of tons of carbon dioxide into the atmosphere each year.
