Implications of the recent fluctuations in the growth rate of tropospheric methane [PDF]
, 2002 Global measurements show that the mixing ratio of tropospheric methane (CH4) increased by 1.1% (19.5 ± 1.7 ppbv) over the five-year period 1996-2000, with striking fluctuations in its annual growth rate.

Vadose zone air as a biogenic source of methane in Nerja Cave system (South of Spain) [PDF]
, 2018 Subterranean air in karst cavities has often low methane contents in comparison to atmosphere and so karst systems have been considered a sink of atmospheric methane. Methane-oxidizing bacteria have been hypothesized as responsible for CH4 depletion in

Effect of permafrost thaw on CO2 and CH4 exchange in a western Alaska peatland chronosequence [PDF]
, 2014 Permafrost soils store over half of global soil carbon (C), and northern frozen peatlands store about 10% of global permafrost C. With thaw, inundation of high latitude lowland peatlands typically increases the surface-atmosphere flux of methane (CH4), a
