Causes of Global Warming

The first step in stopping global warming is knowing its causes. Most if not all scientists agree on what causes global warming

Carbon dioxide is the principal green house gas. Power plants which generate electricity also produces carbon dioxide, in 2002 about 40% of U.S. carbon dioxide emissions was from the burning of fossil fuels to generate electricity. About 20% of U.S. carbon dioxide emissions come from cars, which run on gasoline, the most cars that contribute to global warming are cars with poor gas mileage. Truck used mostly for commercial purposes also produce carbon dioxide. Airplanes that in the near future will be used more and more also produce carbon dioxide. Methane is the second after carbon dioxide in the green house gases. Methane is produced from sources like rice paddies, bovine flatulence, bacteria in bogs and fossil fuel production. Nitrous oxide is another green house gas; man-made sources of nitrous oxide include nylon and nitric acid production and the use of fertilizers in agriculture. Last but not least is deforestation; by cutting down all these trees we are increasing the amount of carbon dioxide in the atmosphere.

Now we now most if not all the causes of global warming, and by knowing the causes, this means that we are capable of stopping global warming.
