  2. Greenhouse gas emissions from wetlands - Wikipedia

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

    A heat map of the planet showing methane emissions from wetlands from 1980 to 2021. 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.

    A massive surge in wetlands methane — unaccounted for by national emissions plans and undercounted in scientific models — could raise the pressure on governments to make deeper cuts from their ...

  4. Methane - Wikipedia

    en.wikipedia.org/wiki/Methane

    Wetlands are the largest natural sources of methane to the atmosphere, [47] accounting for approximately 20 – 30% of atmospheric methane. [48] Climate change is increasing the amount of methane released from wetlands due to increased temperatures and altered rainfall patterns. This phenomenon is called wetland methane feedback. [49]

  5. Marsh gas - Wikipedia

    en.wikipedia.org/wiki/Marsh_gas

    This process is called hydrodynamic transport, and it accounts for more than half of nighttime methane fluxes as well as 32% of annual methane emissions from wetland environments. [3] Ebullition, also known as bubbling, is a type of one-way transport of gases from nutrient rich sediments, to the water column, and then to the atmosphere.

  6. Record leap in methane levels as greenhouse gases reach new ...

    www.aol.com/record-leap-methane-levels...

    Methane, a strong but short-lived greenhouse gas, is produced from a range of sources, including natural wetlands, agriculture and fossil fuel production.

  7. Peatland - Wikipedia

    en.wikipedia.org/wiki/Peatland

    Fully water-saturated wetland soils allow anaerobic conditions to manifest, storing carbon but releasing methane. [48] Wetlands make up about 5-8% of Earth's terrestrial land surface but contain about 20-30% of the planet's 2500 Gt soil carbon stores. [49] Peatlands contain the highest amounts of soil organic carbon of all wetland types. [50]

  8. Atmospheric methane - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_methane

    Wetland soils, however, are often sources of atmospheric methane rather than sinks because the water table is much higher, and the methane can be diffused fairly easily into the air without having to compete with the soil's methanotrophs. [73] Methanotrophic bacteria also occur in the underwater sediments.

  9. Minerotrophic - Wikipedia

    en.wikipedia.org/wiki/Minerotrophic

    Stable water and nutrient availability via groundwater systems allows for a diverse array of plant species to grow in minerotrophic wetlands. [4] This also allows for peat to accumulate provided the water does not flow too quickly. [4] A minerotrophic wetland may be alkaline or weakly acidic, which also influences vegetation communities.
