   You really need to make up your mind!  You claim (correctly) that water   
   vapor is a greenhouse gas that is far more potent than carbon dioxide,   
   and yet, as I have pointed out to you ad nauseam, Venus has less total   
   water vapor in its atmosphere than does our World.  And, so, if CO2 is   
   not trapping the extreme heat there, what is?  It can't be H2O; there is   
   simply not enough of it!  What gases, then, are responsible, if not CO2??   
      
   But, if that does not convince you, what about the planet Mars, which   
   has very little water vapor in its atmosphere (far less than our World),   
   and yet, its lowest temperatures (at its poles) are above those of the   
   night side of Mercury??  With an atmospheric pressure only 1% of our   
   World, Mars coldest night temperatures are still above those of   
   Mercury's even at a distance of 1.5 AU from the Sun.   
      
   And, so, if you just want to consider water vapor as such pertains to   
   the nighttime temperatures of Venus, Earth and Mars, none of what you   
   are saying makes sense:   
      
   Venus -- 5.9 x 10^15 kg of water vapor results in 460 C nighttime temps.   
   Earth -- 1.27 x 10^16 kg of water vapor results in 15 C day & night.   
   Mars  -- 7.5 x 10^12 kg of water vapor results in -70 C nighttime temps.   
      
   Now, here are the surface solar constants for each of the above Worlds:   
      
   Venus:  157 W/m²   
   Earth:  340 W/m²   
   Mars :  200 W/m²
