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).
The atmosphere is made up of many different gases. Several gases have the ability to reflect the sun's energy radiating from the earth back to the earth as heat. The gases with this capability are known as greenhouse gases (GHGs). The main GHGs are water vapor, carbon dioxide, methane, and nitrous oxide. Without some level of GHGs in the atmosphere, the earth would be much colder than it is and life on this planet would be much different.
