- Correct me if I am wrong, but I believe that the current atmospheric
- studies on Venus indicate very little, if any water content in the
- atmosphere, having been either evaporated or destroyed by UV
- radiation. Since it was probably the water in the Earth's atmosphere
- which was allowed to rain down onto the Earth because of cooler
- temperatures here than at Venus, cleansing the atmosphere of carbon
- dioxide, as well as forming oceans in which the carbon dioxide could
- dissolve, later locking some of it in the rocky material at the bottom
- of these early sees, how is it proposed to do the same thing on Venus,
- "automatically"?
