  2. Atmospheric methane - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_methane

    The concentration of atmospheric methane is increasing due to methane emissions, and is causing climate change. [3] [4] Methane is one of the most potent greenhouse gases. [5]: 82 Methane's radiative forcing (RF) of climate is direct, [6]: 2 and it is the second largest contributor to human-caused climate forcing in the historical period.

  3. Methane emissions - Wikipedia

    en.wikipedia.org/wiki/Methane_emissions

    Emissions of methane into the atmosphere are directly related to temperature and moisture. Thus, the natural environmental changes that occur during seasonal change act as a major control of methane emission. Additionally, even changes in temperature during the day can affect the amount of methane that is produced and consumed. [citation needed]

  4. Greenhouse gas emissions from wetlands - Wikipedia

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

    A changing climate affects many factors within the ecosystem, including water table, temperature, and plant composition within the wetland—all factors that affect methane emissions. However, climate change can also affect the amount of carbon dioxide in the surrounding atmosphere, which would in turn decrease the addition of methane into the ...

  5. 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]

  6. Greenhouse gas emissions - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions

    Carbon dioxide (CO 2) is the main greenhouse gas resulting from human activities. It accounts for more than half of warming. Methane (CH 4) emissions have almost the same short-term impact. [4] Nitrous oxide (N 2 O) and fluorinated gases (F-gases) play a lesser role in comparison.

  7. Deforestation and climate change - Wikipedia

    en.wikipedia.org/wiki/Deforestation_and_climate...

    Deforestation is a primary contributor to climate change, [ 1 ][ 2 ] and climate change affects the health of forests. [ 3 ] Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. [ 4 ][ 5 ] Greenhouse gases are emitted from ...

  8. Clathrate gun hypothesis - Wikipedia

    en.wikipedia.org/wiki/Clathrate_gun_hypothesis

    Clathrate gun hypothesis. Methane clathrate is released as gas into the surrounding water column or soils when ambient temperature increases. The clathrate gun hypothesis is a proposed explanation for the periods of rapid warming during the Quaternary. The hypothesis is that changes in fluxes in upper intermediate waters in the ocean caused ...
