Now consider that: During the Carboniferous period when huge deposits of calamites were laid down (later to be pressed into coal through diagenesis) the CO2 / O2 curves significantly diverged. Could it be that the C-O2 bond was broken and the C store in the coal?

Look at the P-T horizon. The largest extinction ever, initiated rapid and significant temperature rises (Wilkes Land Meteorite and the resultant [antipodal] Siberian Traps [hypothesis]). The PT event also preceded a sharp drop in O2 and a sharp rise in CO2. BUT, no such reaction to the Chixulub K-T horizon extinction event (beginning of the Cenozoic).

Atmospheric oxygen concentration continues to rise since the T-J Extinction and CO2 continues to fall.

What is the role of mankind in the “catastrophic rise” in CO2 ?
