Gases in Earth's AtmosphereImpacts on The Overall Greenhouse EffectNatural and Anthropogenic SourcesRemoval from The AtmosphereHistory of Scientific ResearchFurther ReadingExternal LinksNon-greenhouse gasesThe major constituents of Earth's atmosphere, nitrogen (N2) (78%), oxygen (O2) (21%), and argon (Ar) (0.9%), are not greenhouse gases because molecules containing two atoms of the same element such as N2 and O2 have no net change in the distribution of their electrical chargGreenhouse gasesGreenhouse gases are those that absorb and emit infrared radiation in the wavelength range emitted by Earth.Carbon dioxide (0.04%), nitrous oxide, methane, and ozone are trace gases that account for almost 0.1% of Earth's atmosphere and have an appreciable greenhouse effect. ThIndirect radiative effectsOxidation of CO to CO2 directly produces an unambiguous increase in radiative forcing although the reason is subtle. The peak of the thermal IR emission from Earth's surface is very close to a strong vibrational absorption band of CO2 (wavelength 15 microns, or wavenumber 667 cm−1).
