>> you cannot compare Venus with its proximity to the sun

Which of course explains why average temp on Venus is much higher than average temp on Mercury even though average Mercury insolation is about 3x that of Venus.

You actually can't look only at distance to the sun and greenhouse effect - you also have to look at albedo. Average Venus insolation is about twice that of the Earth, but Venus albedo is way higher as the cloudy atmosphere reflects most of the sunlight. So net net, I think absorbed energy from insolation is about the same (or maybe even lower for Venus).

(Really my last word on the subject)
