  2. Atmosphere of Mars - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Mars

    The atmosphere of Mars is the layer of gases surrounding Mars.It is primarily composed of carbon dioxide (95%), molecular nitrogen (2.85%), and argon (2%). [3] It also contains trace levels of water vapor, oxygen, carbon monoxide, hydrogen, and noble gases.

  3. Terraforming of Mars - Wikipedia

    en.wikipedia.org/wiki/Terraforming_of_Mars

    Because its atmosphere consists mainly of CO 2, a known greenhouse gas, once Mars begins to heat, the CO 2 may help to keep thermal energy near the surface. Moreover, as it heats, more CO 2 should enter the atmosphere from the frozen reserves on the poles, enhancing the greenhouse effect. This means that the two processes of building the ...

  4. Terraforming - Wikipedia

    en.wikipedia.org/wiki/Terraforming

    Terraforming Mars would entail two major interlaced changes: building the atmosphere and heating it. [40] A thicker atmosphere of greenhouse gases such as carbon dioxide would trap incoming solar radiation. Because the raised temperature would add greenhouse gases to the atmosphere, the two processes would augment each other. [41]

  6. Mars carbonate catastrophe - Wikipedia

    en.wikipedia.org/wiki/Mars_carbonate_catastrophe

    The carbonates removed (leached) greenhouse gases, water vapor, and carbon dioxide from the atmosphere. Carbonates still exist on Mars. Early greenhouse gases came from Mars' early magma, planetesimals and comets. The carbonate catastrophe ended the Noachian time span. Mars' interior cooled, so it did not develop plate tectonics and a carbon ...

    On the current rate at which carbon dioxide and other gases are building up in the atmosphere, the world will see temperature rises well beyond 1.5C. Levels of climate-warming greenhouse gases in ...

  8. Climate of Mars - Wikipedia

    en.wikipedia.org/wiki/Climate_of_Mars

    Carbon dioxide is a greenhouse gas that raises a planet's temperature: it traps heat by absorbing infrared radiation. Thus, Tharsis volcanoes, by giving off CO 2, could have made Mars more Earth-like in the past. Mars may have once had a much thicker and warmer atmosphere, and oceans or lakes may have been present. [11]
