But who on Earth is so fond of CO2? right, plants via photosyntesis.

So why not sending green algae on Venus to harvest that CO2? When the temp drops, send something else, like trees.

Quite SF, but would worth a calculation.




If you want plants to do it, you need water, and there isn't any. The solar wind blew it all away.

Not just because "plants need water", because the chemistry is CO2 + H20 => O2 + carbohydrate


Indeed, you are right. Interesing link on this subject [1], it explains a bit more in detail the greenhouse runway process.

Plants can't photosynthesize without water. No hydrogen, no water, no photosynthesis to take CO2 out of the atmosphere.
