After a decade of near-zero growth in methane levels, "globally averaged atmospheric methane increased by [approximately] 7 nmol/mol per year during 2007 and 2008. During the first half of 2009, globally averaged atmospheric CH 4 was [approximately] 7 nmol/mol greater than it was in 2008, suggesting that the increase will continue in 2009."
Atmospheric methane removal is a category of potential approaches being researched to accelerate the breakdown of methane that is in the atmosphere, for the purpose of mitigating some of the impacts of climate change. [1] Atmospheric methane has increased since pre-industrial times from 0.7 ppm to 1.9 ppm. [2]
This high level of water saturation creates conditions conducive to methane production. Most methanogenesis , or methane production, occurs in oxygen-poor environments. Because the microbes that live in warm, moist environments consume oxygen more rapidly than it can diffuse in from the atmosphere, wetlands are the ideal anaerobic environments ...
More than 70% of atmospheric methane comes from biogenic sources. Methane levels have risen gradually since the onset of the industrial era, [13] from ~700 ppb in 1750 to ~1775 ppb in 2005. [10] Methane can be removed from the atmosphere through a reaction of the photochemically produced hydroxyl free radical (OH).
