  2. Inert gas - Wikipedia

    en.wikipedia.org/wiki/Inert_gas

    The term inert gas is context-dependent because several of the inert gases, including nitrogen and carbon dioxide, can be made to react under certain conditions. [1] [2] Purified argon gas is the most commonly used inert gas due to its high natural abundance (78.3% N 2, 1% Ar in air) [3] and low relative cost.

  3. Atmospheric methane - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_methane

    Methane (CH 4) concentrations in the atmosphere measured by the Advanced Global Atmospheric Gases Experiment (AGAGE) in the lower atmosphere (troposphere) at stations around the world. Values are given as pollution free monthly mean mole fractions in parts-per-billion. [1] Atmospheric methane is the methane present in Earth's atmosphere. [2]

  4. Methane - Wikipedia

    en.wikipedia.org/wiki/Methane

    Methane is extremely flammable and may form explosive mixtures with air. Methane gas explosions are responsible for many deadly mining disasters. [84] A methane gas explosion was the cause of the Upper Big Branch coal mine disaster in West Virginia on April 5, 2010, killing 29. [85]

    Methane emissions in the atmosphere come from natural wetlands, agriculture, livestock, landfills and leaks and intentional flaring of natural gas in the oil and gas industry. Methane is ...

  6. Atmosphere of Earth - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Earth

    The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes), all retained by Earth's gravity.

    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 ...

  8. Atmospheric carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_carbon_cycle

    Methane (CH 4) is one of the more potent greenhouse gases and is mainly produced by the digestion or decay of biological organisms. It is considered the second most important greenhouse gas, [10] yet the methane cycle in the atmosphere is currently only poorly understood. [11] The amount of methane produced and absorbed yearly varies widely. [10]

    Methane, a potent greenhouse gas that traps heat in the atmosphere and warms the planet much faster than carbon dioxide in the short term, is considered a top threat to the climate.
