Do you know the history of the atmosphere of Venus? Or of Venus
itself,
for
that matter?

I know what I've read. The general consensus seems to be that billions
of
years ago it had large amounts of water but also large amounts of CO2.
The
CO2 heated the planet up beyond the boiling point of water despite the
sun
being weaker then and the rest is history. Anyway , this is getting way
off
topic. The point is more CO2 = more heat trapped. Thats simple physics
and
you cannot argue your way out of it.

I haven't said that there isn't. However, there is also a chain of
chemical
reactions forming the Carbon cycle, and those reactions have kinetics and
equilibria which are temperature dependent. That restrains the level of
CO2
in the atmosphere.
