How important are the non-carbon dioxide greenhouse gases?
Non-CO2 greenhouse gases (GHGs) include water vapor; methane; ozone; nitrous oxide (N2O); the group of fluorinated gases consisting of hydroflurocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6); and chlorofluorocarbons (CFCs). CO2, methane, water vapor, N2O, and ozone are naturally occurring as well as anthropogenic GHGs; the other compounds are strictly Anthropogenic – Sourced from human activity.’, 220)” ;=”” onmouseout=”hideddrivetip()”>anthropogenic.
