  2. Methane emissions - Wikipedia

    en.wikipedia.org/wiki/Methane_emissions

    Methane emissions occur in all sectors of the natural gas industry, from drilling and production, through gathering and processing and transmission, to distribution. These emissions occur through normal operation, routine maintenance, fugitive leaks, system upsets, and venting of equipment.

  3. Atmospheric methane - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_methane

    [5]: 82 Methane's radiative forcing (RF) of climate is direct, [6]: 2 and it is the second largest contributor to human-caused climate forcing in the historical period. [6]: 2 Methane is a major source of water vapour in the stratosphere through oxidation; [7] and water vapour adds about 15% to methane's radiative forcing effect. [8]

  4. Methane - Wikipedia

    en.wikipedia.org/wiki/Methane

    Methane is a tetrahedral molecule with four equivalent C–H bonds. Its electronic structure is described by four bonding molecular orbitals (MOs) resulting from the overlap of the valence orbitals on C and H. The lowest-energy MO is the result of the overlap of the 2s orbital on carbon with the in-phase combination of the 1s orbitals on the ...

    en.wikipedia.org/wiki/Fossil_fuel

    A fossil fuel[a] is a carbon compound - or hydrocarbon -containing material such as coal, oil, and natural gas, [2] formed naturally in the Earth's crust from the remains of prehistoric organisms (animals, plants and planktons), a process that occurs within geological formations. Reservoirs of such compound mixtures can be extracted and burned ...

  9. Methanogenesis - Wikipedia

    en.wikipedia.org/wiki/Methanogenesis

    Methanogenesis or biomethanation is the formation of methane coupled to energy conservation by microbes known as methanogens.Organisms capable of producing methane for energy conservation have been identified only from the domain Archaea, a group phylogenetically distinct from both eukaryotes and bacteria, although many live in close association with anaerobic bacteria.
