  2. Carbon sequestration - Wikipedia

    en.wikipedia.org/wiki/Carbon_sequestration

    Carbon dioxide forms carbonic acid when dissolved in water, so ocean acidification is a significant consequence of elevated carbon dioxide levels, and limits the rate at which it can be absorbed into the ocean (the solubility pump).

  3. Carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide

    Carbon dioxide is a chemical compound with the chemical ... Absorption of infrared light at the vibrational frequencies of atmospheric CO 2 traps energy near the ...

  4. Carbon sink - Wikipedia

    en.wikipedia.org/wiki/Carbon_sink

    Absorption of carbon dioxide by the oceans via solubility and biological pumps. Artificial carbon sinks are those that store carbon in building materials or deep underground (geologic carbon sequestration). [11] [12] No major artificial systems remove carbon from the atmosphere on a large scale yet. [13]

  5. Carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Carbon_cycle

    Carbon dioxide is removed from the atmosphere primarily through photosynthesis and enters the terrestrial and oceanic biospheres. Carbon dioxide also dissolves directly from the atmosphere into bodies of water (ocean, lakes, etc.), as well as dissolving in precipitation as raindrops fall through the atmosphere. When dissolved in water, carbon ...

  6. Ocean acidification - Wikipedia

    en.wikipedia.org/wiki/Ocean_acidification

    Carbon dioxide emissions from human activities are the primary cause of ocean acidification, with atmospheric carbon dioxide (CO 2) levels exceeding 422 ppm (as of 2024). [3] CO 2 from the atmosphere is absorbed by the oceans.

  7. Greenhouse effect - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_effect

    Longwave absorption coefficients of water vapor and carbon dioxide. For wavelengths near 15 microns (15 μ m in top scale), where Earth's surface emits strongly, CO 2 is a much stronger absorber than water vapor.

  8. Carbon dioxide scrubber - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_scrubber

    A carbon dioxide scrubber is a piece of equipment that absorbs carbon dioxide (CO 2). ... The absorption reaction is a gas liquid reaction, strongly exothermic, here:

  9. 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]
