the first 20PPM of CO2 have more effect on the climate than all the rest combined.
both Venus and Mars have atmospheres comprised of mostly CO2 but Mars has a very thin one. Venus has a thick atmosphere but it does not have a resevoir of a substance like water that changes from liquid to gas which takes latent (phase change) heat from the surface to the top of the atmosphere. Earth has a stable temperature because water via evaporation and clouds has a mechanism to shed or conserve heat depending on conditions. that is why the earth had liquid water billions of years ago when the sun's output was 4 percent less than today.
The first 20 ppm is more important? That contradicts your own statement that effect of CO2 is logarithmic. Given a CO2 of 380 ppm today, that means the next 360 was TWICE as important as the first 20. Do the math!!!
konrad, you need to go to a university and have one of the math profs teach you about logarithims. Really you do.
Advice comes a bit late West..........he's already enrolled in the University of Mars.
