Methane is more potent than CO2, but fairly short lived. Maybe Mars had more Methane in the distant past? If a 95% CO2 atmosphere isn't enough green house gas for liquid water, I'd assume internal heat played some sort of role.
- cesis 10y agoMethane is short-lived because of oxygen.
- ChuckMcM 10y agoMy guess is methane as well, Mars still "breathes" out methane occasionally[1]. Given that chunks of Mars have been kicked off the planet and landed on Earth, I wonder if you modeled a chunk of Titan's methane ice being kicked off Titan and hitting Mars would have the effect of filling out enough of Mars' atmosphere to warm it.
