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. An exception are purely human … 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 • Attribution of recent climate change • Cap and Trade See more WebAug 25, 2011 · The lifetime of a greenhouse gas refers to the approximate amount of time it would take for the anthropogenic increment to an atmospheric pollutant concentration to return to its natural level as a result of either being converted to another chemical compound or being taken out of the atmosphere via a sink. This time depends on the pollutant's ...

WebApr 9, 2024 · H2O Is Liquid Because Of Its Ability To Form Hydrogen Bonds Which Is Possible Only In Case Of F , O And N Because Of Their High Electronegativity. Hence, water has a higher boiling point (or is a liquid at room temperature) whereas h 2 s is a gas at room temperature. Consequently h2o is liquid while h2s is gas.
