Where is the climate change data that compares percentage of plankton type CO2 vs O2 in the earths oceans?

Most people who take for granted this climate change have no idea its all made up: Ice core charts that don't match the fossil record or even show 79A.D. massive volcanic blow off that doubled the earths CO2 levels for decades that the fossil record shows from sedimentary quarries that CO2 consuming plankton's multiplied to control and return earths equilibrium.
