Could you please point us to any sources of information on historical levels of oxygen into atmosphere? Does it grow,fall or stay constant? Otherwise the source of extra carbon dioxide in the atmosphere stays questionable. For example ocean warming may increase it without fossil fuels burning and completely independent of human activity.

I suggest that you take a ride on the google machine yourself.
