Proposed merge of Climate of Mars into Atmosphere of Mars

[edit]

Oppose. There is not "wide overlap". Sure, there is some overlap, but considering the length of both articles, and the amount of unique content in each, merging the articles would simply make one of the articles far too long. aaronneallucas (talk) 01:28, 2 January 2023 (UTC)[reply]
Oppose While there is some overlap in the topic of the atmosphere, the climate-related article contains a lot of information that isn't directly related to the atmosphere. Joyous! | Talk 18:12, 27 February 2023 (UTC)[reply]
Closing, given the uncontested objections and no support. Klbrain (talk) 10:20, 30 April 2023 (UTC)[reply]

Atmosphere of Mars

The atmosphere of Mars is a layer of gases surrounding Mars, which is composed primarily of carbon dioxide (95%), along with molecular nitrogen (2.8%), and argon (2%) and trace levels of other compounds. The Martian atmosphere is much thinner than Earth's, its average surface pressure of 610 pascals (0.088 psi) being less than 1% of the Earth's value. This prohibits the existence of liquid water on the surface of Mars, but many studies suggest that the Martian atmosphere was much thicker in the past. The effective temperature at the surface is around 210 K (−63 °C; −82 °F), and it has a large daily temperature range due to the low thermal inertia; in some regions it can vary from −75 °C (−103 °F) to near 0 °C (32 °F). Dust devils and dust storms are prevalent on Mars, which are sometimes observable by telescopes from Earth, and can threaten the operation of Mars rovers. Planet-encircling dust storms occur on average every 5.5 Earth years (3 Martian years), but the mechanism responsible for these storms is not well understood. This small dust devil was captured by NASA's Curiosity rover in 2020.

carbon dioxide vs water

[edit]

i took out a sentence saying water vapor would make Mars warmer, and t hen self-reverted. CO2 is much more powerful than water vapor, and at global warming potential we say water may even be negative. but it seems the relationship isnt proportional to total amt in atmosphere, so i self-reverted. i will try to look into this if i get a chance.Soap 23:05, 2 August 2023 (UTC)[reply]
