greenhouse gases

Trace gases that contribute to the greenhouse effect, mainly carbon dioxide, methane, nitrous oxide, and chlorofluoro­carbons; components of the atmosphere that contribute to the greenhouse effect; any gas that contributes to the greenhouse effect; gaseous constituents of the atmosphere, both natural and from human activity, that absorb and re-emit infrared radiation. Water vapor (H2O) is the most abundant greenhouse gas. Greenhouse gases are a natural part of the atmosphere and include carbon dioxide (CO2), methane (CH4, persisting 9-15 yrs with a greenhouse warming potential (GWP) 22 times that of CO2), nitrous oxide (N2O persists 120 years and has a GWP of 310), ozone (O3),hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride.
