Now the modelers can turn their efforts to Mars and explain how a planet with an atmosphere that's 95% CO2, manages to stay cold rather than have runaway greenhouse warming.

There's also a slight matter of atmospheric density and the amount of water vapor in the atmosphere. Water vapor is the primary greenhouse gas.

I agree. It's more complicated than simply the percent of CO2 present.

I was being facetious.
