Along with carbon dioxide (CO 2 ), nitrous oxide (N 2 O),and chlorofluorocarbons (CFCs), methane (CH 4 ) concentrations in the atmosphere have increased markedly since the industrial revolution [ Ledley et al , 1999] .These so‐called greenhouse gases, along with water vapor, are generally considered to be the major players in the current global warming trend. Just how much global warming is due to anthropogenic contributions has not been resolvedsemi; however, recent increases in the atmospheric concentration of methane are undeniable. The bulk of the atmospheric methane increase has been attributed to the burning of fossil fuels and biomass, wetlands and flooded crops, natural gas seeps, and emissions from domesticated animals and landfills.
