   So does cold water hold more dissolved N2 and O2 than hot water.  So by   
   your logic we should be seeing the total N2 and O2 content of the   
   atmosphere rise approximately 50% over the last couple centuries like   
   CO2.  Have you heard any such reports?

   Are you saying natural processes are absorbing and releasing large   
   amounts of CO2 already, presumably for a net absorption of zero, so it's   
   fine for humans to also release CO2 without ever reabsorbing any?

   If true, your numbers seem to deny that CO2 has risen 50% since   
   pre-industrial.  How do you explain that?
