I was kicking around an alternate history for a roleplaying session and got to thinking about swelling up Mars a bit, like in Harry Turtledove's "A World of Difference."

The idea is that plus-sized Mars would still be red and lifeless (?), so it wouldn't alter human history. (Lots of religions depend on Mars being red.) However, it'd be larger (surface gravity ~0.8G) and have a thicker atmosphere (~0.7 bar.) If that atmosphere was 80% nitrogen and 20% carbon dioxide, what would that do for the Martian climate?

Are there any handy planet climate modelers to figure out a planet's average temperature based on pressure, CO2 levels, and insolation?
