Many greenhouse gases occur naturally in the atmosphere, such as carbon dioxide, methane, water vapor, and nitrous oxide, while others are synthetic. Those that are man-made include the chlorofluorocarbons (CFCs) , hydrofluorocarbons (HFCs) and Perfluorocarbons (PFCs), as well as sulfur hexafluoride (SF 6).
Poor old CO2! :-) There are only two main gases in the air, oxygen and nitrogen.... You could class carbon dioxide but that is only 1%..... However, interestingly enough, even though there is only about 1% carbon dioxide in the air you can go anywhere you want in the world and you'll always get a reading of about 5%....
