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).
Earth's Greenhouse Gases. Even though only a tiny amount of the gases in Earth s atmosphere are greenhouse gases, they have a huge effect on climate. There are several different types of greenhouse gases. The major ones are carbon dioxide, water vapor, methane, and nitrous oxide.All of these have molecules with three or more atoms.The atoms are held together loosely enough that they vibrate when they absorb heat.ven though only a tiny amount of the gases in Earth s atmosphere are greenhouse gases, they have a huge effect on climate.
