  2. Greenhouse effect - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_effect

    The planet Venus experienced a runaway greenhouse effect, resulting in an atmosphere which is 96% carbon dioxide, and a surface atmospheric pressure roughly the same as found 900 m (3,000 ft) underwater on Earth. Venus may have had water oceans, but they would have boiled off as the mean surface temperature rose to the current 735 K (462 °C ...

  3. Greenhouse gas - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas

    This is an accepted version of this page This is the latest accepted revision, reviewed on 9 December 2024. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...

  4. Runaway greenhouse effect - Wikipedia

    en.wikipedia.org/wiki/Runaway_greenhouse_effect

    Through this effect, a runaway feedback process may have removed much carbon dioxide and water vapor from the atmosphere and cooled the planet. Water condenses on the surface, leading to carbon dioxide dissolving and chemically binding to minerals. This reduced the greenhouse effect, lowering the temperature and causing more water to condense.

  5. Illustrative model of greenhouse effect on climate change

    en.wikipedia.org/wiki/Illustrative_model_of...

    Absorption cross sections for CO2 (green) and water vapour (purple). The wavelengths most relevant to climate change are those where the green plot crosses the upper horizontal line, representing a CO2 level somewhat larger than the current concentration. CO 2 absorbs the ground's thermal radiation mainly at wavelengths between 13 and 17 micron ...

  6. Carbon dioxide in Earth's atmosphere - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_in_Earth's...

    In Earth's atmosphere, carbon dioxide is a trace gas that plays an integral part in the greenhouse effect, carbon cycle, photosynthesis and oceanic carbon cycle. It is one of three main greenhouse gases in the atmosphere of Earth. The concentration of carbon dioxide (CO 2) in the atmosphere reached 427 ppm (0.04%) in 2024. [1]

  7. Carbon dioxide - Wikipedia

    In Earth's atmosphere, carbon dioxide is a trace gas that plays an integral part in the greenhouse effect, carbon cycle, photosynthesis and oceanic carbon cycle. It is one of three main greenhouse gases in the atmosphere of Earth. The concentration of carbon dioxide (CO 2) in the atmosphere reached 427 ppm (0.04%) in 2024. [78]

  8. Carbon sequestration - Wikipedia

    en.wikipedia.org/wiki/Carbon_sequestration

    When the nutrient rich deep ocean water is moved to the surface, algae bloom occurs, resulting in a decrease in carbon dioxide due to carbon intake from phytoplankton and other photosynthetic eukaryotic organisms. The transfer of heat between the layers will also cause seawater from the mixed layer to sink and absorb more carbon dioxide.

  9. Infrared window - Wikipedia

    en.wikipedia.org/wiki/Infrared_window

    The infrared atmospheric window is an atmospheric window in the infrared spectrum where there is relatively little absorption of terrestrial thermal radiation by atmospheric gases. [1] The window plays an important role in the atmospheric greenhouse effect by maintaining the balance between incoming solar radiation and outgoing IR to space.
