I've worked out the equilibrium temperature w/o greenhouse gases. Does anyone know a not too difficult explanation how to take into account the co2 blanketing effect in that radiation balance as a function of the %?
Wow.... the CO2 contribution should be an extra coefficient on that equilibrium level that you already calculated for the normal atmosphere.
You just need to know how much Infrared gets absorbed by CO2, depending on the concentration in the atmosphere...
Or how much more CO2 absorbs, when compared with O2 and N2... I tried searching for it, but couldn't find it in 5 minutes... Best luck to you.
