re: Ok, so off to Mars
"Now in a cubic meter of Earth air there is .035% of it CO2 or per million parts there is 350 parts CO2. This means that in a cubic meter of Earth air the density of CO2 is .0004305 kg/m3. "
I should have times this number by 1.5, so instead the density of CO2 is .00064575 kg/m3
"Which means there there is 46.4576 times CO2 in a cubic meter of Mars air as there is in Earth's air."
Correction: 30.97 times.
Anyways, keeping it short, it works out that instead 6.48 C, it's 4.2 C.
Which is on the other side of 5 C , the stated greenhouse affect of Mars.
