  2. Atmospheric methane - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_methane

    Atmospheric methane is the methane present in Earth's atmosphere. [2] ... [50] From 2015 to 2019 sharp rises in levels of atmospheric methane have been recorded.

  3. Methane emissions - Wikipedia

    en.wikipedia.org/wiki/Methane_emissions

    The atmospheric methane (CH 4) concentration is increasing and exceeded 1860 parts per billion in 2019, equal to two-and-a-half times the pre-industrial level. [19] The methane itself causes direct radiative forcing that is second only to that of carbon dioxide (CO 2). [20]

  4. Atmospheric carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_carbon_cycle

    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).

    Increases in levels of carbon dioxide – the main greenhouse gas – from 2020 to 2021 was larger than the average annual growth rate over the last decade, with concentrations reaching 415.7 ...

    Scientists are also worried about the rapid rise in atmospheric levels of methane, a shorter-lived but more potent heat-trapping gas. Both jumped 5.5% over the past decade.

  7. Atmospheric methane removal - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_methane_removal

    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]

  8. Greenhouse gas emissions from wetlands - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions...

    Greenhouse gas emissions from wetlands of concern consist primarily of methane and nitrous oxide emissions. Wetlands are the largest natural source of atmospheric methane in the world, and are therefore a major area of concern with respect to climate change. [1][2][3] Wetlands account for approximately 20–30% of atmospheric methane through ...

  9. Arctic methane emissions - Wikipedia

    en.wikipedia.org/wiki/Arctic_methane_emissions

    Atmospheric methane concentrations are 8–10% higher in the Arctic than in the Antarctic atmosphere. During cold glacier epochs, this gradient decreases to insignificant levels. [ 19 ] Land ecosystems are thought to be the main sources of this asymmetry, although it has been suggested in 2007 that "the role of the Arctic Ocean is significantly ...
