One of the things ignored in looking at the Martian atmosphere is the total lack of global warming, in spite of the fact that the atmosphere,though thin, is still thick enough to fly a helicopter in. Mar’s atmosphere is composed of 93% CO2, and there is in total ten times as much CO2 on Mars as we have on earth...absolute amount, not percentage. And no fossils or humans had anything to do with its presence.
If you were to model CO2 warming, you couldn’t pick a better place than Mars.
