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 In the late 19th century, scientists experimentally discovered that N 2 and O 2 do not absorb infrared radiation (called, at that time, "dark radiation"), while water (both as true vapor … 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.
