Speaking of facts, one fact is that CO2 concentration iincreases in
saturation as water gets colder, not warmer as is the case with say,
dissolving sugar in water.  If  the oceans are getting warmer, AND the
CO2 levels of the atmosphere are increasing, wouldn't that imply that
the dissolved CO2 levels in the ocean would decrease as temperature
increases, increasing atmospheric CO2? There is also the pressure
factor-- the CCM boundary number is reflective of how much pressure is
required in essence, to force CO2 out of solution below that level. And
the buffering depends upon the amount of calcium and other elements
available in suspension to react with the CO2 and carbonate (in its
various anionic forms). .

This is not an easy scenario to model, as  the various levels of the
ocean water column react differently --somewhat like one of those
multicolored Jell-O desserts. The entire column cannot be treated as
uniform. 

This is definitely food for thought, however. Thanks George.
