  2. Greenhouse gas monitoring - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_monitoring

    Greenhouse gas monitoring is the direct measurement of greenhouse gas emissions and levels. There are several different methods of measuring carbon dioxide concentrations in the atmosphere, including infrared analyzing and manometry. Methane and nitrous oxide are measured by other instruments.

  3. Atmospheric methane - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_methane

    The atmospheric methane concentration has continued to increase since 2011 to an average global concentration of 1911.8 ± 0.6 ppb as of 2022. [16] The May 2021 peak was 1891.6 ppb, while the April 2022 peak was 1909.4 ppb, a 0.9% increase. [55] Annual atmospheric methane concentrations from 1990 to 2021.

  4. Methane emissions - Wikipedia

    en.wikipedia.org/wiki/Methane_emissions

    The most clearly identified rise in atmospheric methane as a result of human activity occurred in the 1700s during the industrial revolution. During the 20th century—mainly because of the use of fossil fuels—concentration of methane in the atmosphere increased, then stabilized briefly in the 1990s, [56] only to begin to increase again in ...

    The levels of the crucial heat-trapping gases in the atmosphere reached historic highs last year, growing at near-record fast paces, according to the U.S. National Oceanic and Atmospheric ...

  6. Carbon monitoring - Wikipedia

    en.wikipedia.org/wiki/Carbon_monitoring

    Carbon monitoring as part of greenhouse gas monitoring refers to tracking how much carbon dioxide or methane is produced by a particular activity at a particular time. For example, it may refer to tracking methane emissions from agriculture, or carbon dioxide emissions from land use changes, such as deforestation, or from burning fossil fuels, whether in a power plant, automobile, or other device.

  8. Methane - Wikipedia

    en.wikipedia.org/wiki/Methane

    In 2013, atmospheric methane accounted for 20% of the total radiative forcing from all of the long-lived and globally mixed greenhouse gases. [63] Between 2011 and 2019 the annual average increase of methane in the atmosphere was 1866 ppb. [12] From 2015 to 2019 sharp rises in levels of atmospheric methane were recorded. [64] [65]
