Greenhouse gases

Greenhouse gases are, in order of their size: water vapour (H20), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and ozone (O3), to which must be added several artificial fluoride gases: chlorofluorocarbons (CFCs), perfluoromethane (CF4) and sulphuric hexafluoride (SF4).
