Yes I’ve thought about this for ages, however there’s hardly any CO2 in the air that’s the thing a small amount causes the green house warming, but I wouldn’t have thought it’d be easy to remove that small amount out. I don’t know much about CO2 deposition, I assume that’s the opposite of sublimation. However this does happen a lot on Mars. Certainly the fact that photosynthesis can work with such low concentrations is impressive, mind you if it couldn’t work it wouldn’t.
