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?
