   The claim you're trying to make is, frankly, laughable.  First, the monthly
   temperature/monthly CO2 curve works in an opposite direction from what
   you're suggesting in this case.  If there were no terrestrial biota taking
   up and releasing carbon dioxide, we wouldn't be seeing such a seasonal cycle
   in CO2 concentrations.  So no, it's not the temperature driving the seasonal
   cycles in CO2 concentrations, it's the biota.

     Forgive me if I missed something, but are you arguing it is not factual to
     suggest temperature has anything to do with seasonal fluctuation in
     atmospheric CO2 caused by photosynthesis, respiration and decomposition?
     Arent you both talking about the same thing?
