methane"(Also called marsh gas.) Colorless, inflammable gas of formula CH4; the simplest hydrocarbon.
Methane A radiatively active gas that participates in the greenhouse effect; derived from the organic processes of burning, digesting, and rotting in the presence of oxygen; CH4.
Methane (CH4(5)
CH4 is among the six greenhouse gases to be curbed under the Kyoto Protocol.
Water vapor, methane, and carbon dioxide can also act as significant positive feedbacks, their levels rising in response to a warming trend, thereby accelerating that trend.
The most important trace gases contributing to the greenhouse effect are water vapor, carbon dioxide, ozone, methane, ammonia, nitric acid, nitrous oxide, ethylene, sulfur dioxide, nitric oxide, dichlorofluoromethane or Freon 12, ...
This warming is likely due to the increase of so called "greenhouse gases" -- such as CO2, methane and CFCs (chloro-fluorocarbons). These gases absorb outgoing heat from our planet and "reflect" it back to Earth.
Greenhouse gases include carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and water vapor. Carbon dioxide, methane, and nitrous oxide have significant natural and human sources while only industries produce chlorofluorocarbons.
This outgoing longwave radiation is partially trapped by greenhouse gases such as carbon dioxide, methane and water vapour which then radiate the energy in all directions, warming the earth's surface and atmosphere.
Other components are traces of Neon (Ne), Helium (He), Methane (CH4), Krypton (K), Hydrogen (H), Nitrous Oxide (N2O) and Xenon (Xe)

Weather Facts ...
Greenhouse effect- The process by which heat is trapped in the atmosphere by water vapor, carbon dioxide, methane, and other gases that form a "blanket" around Earth.
Greenhouse gases- Gases in the atmosphere that trap heat.
The concentration of ozone is variable, between 10 and 0.1 parts per million. Carbon dioxide, methane, and nitrous oxide have all been increasing since the beginning of the industrial age.
Greenhouse Gas - Certain gases, such as water vapor, carbon dioxide, and methane, that more effectively trap heat affecting the Earth's surface temperature.
The gases that absorb terrestrial radiation and contribute to the greenhouse effect; the main greenhouse gasses are water vapor, methane, carbon dioxide, and ozone.
Ground Blizzard Warning ...
Enhanced greenhouse effect - The natural greenhouse effect has been enhanced by man's emissions of greenhouse gases. Increased concentrations of carbon dioxide, methane and nitrous oxide trap more infra-red radiation, so heating up the atmosphere.
Greenhouse Gases - the gases that absorb terrestrial radiation and contribute to the greenhouse effect; the main greenhouse gasses are water vapor, methane, CO2 and ozone.
Greenhouse gases Infrared-absorbing gases that contribute to the greenhouse effect in the Earth-atmosphere system. The main greenhouse gas is water vapor; others are carbon dioxide, ozone, methane, and nitrous oxide. ...
Chemicals such as methane (CH4) and nitrous oxide (N2O), which are released at the earth's surface and destroyed slowly in the atmosphere, can be used to infer vertical rates of transport.
radiation (mostly visible light) from the sun, than to the long wavelength radiation (infrared radiation) leaving the Earth. These gases then reemit the trapped energy, partly toward the Earth's surface. Examples are carbon dioxide, methane, CFCs, ...
