Global methane emissions are major part of the global greenhouse gas emissions. Methane in the atmosphere has a 100-year global warming potential of 34.Myhre, G., D. Shindell, F.-M. Bréon, W.

Sources of atmospheric methane

Biogenic (b) methane is produced by microorganisms in a process called methanogenesis. Abiogenic (a) methane stored in rocks and soil stems from ancient biomass and the generation mechanisms are the same as for other fossil fuels.

Natural sources

Natural sources that have always been a part of the methane cycle include: With the ongoing draining for agricultural and building areas, wetlands and the associated methane production are on the decline.
