A greenhouse gas (GHG or GhG) is a gas that absorbs and emits radiant energy at thermal infrared wavelengths, causing the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3). … See more The major constituents of Earth's atmosphere, nitrogen (N 2) (78%), oxygen (O 2) (21%), and argon (Ar) (0.9%), are not greenhouse gases because molecules containing two atoms of the same element such as N 2 and O … See more Current concentrations Abbreviations used in the two tables below: ppm = parts-per-million; ppb = parts-per-billion; ppt = parts-per-trillion; W/m = watts per square meter Measurements from ice cores over the past 800,000 years See more Natural processes Greenhouse gases can be removed from the atmosphere by various processes, as a consequence of: See more • Climate change portal • Environment portal • Renewable Energy portal See more The contribution of each gas to the greenhouse effect is determined by the characteristics of that gas, its abundance, and any indirect effects it may cause. For example, the direct radiative effect of a mass of methane is about 84 times stronger than the … See more Natural sources Most greenhouse gases have both natural and human-caused sources.
