Nothing-----
I have measured it for 30 yrs and the ox has been 20.9 %
the green house gases 1.1% and nitrogen 78%
The increase in CO2 not there
Methane not there
Measure it and quit calculating what u want it to be.

Volcanos that put out a lot of CO2 and H2SO4. Power plants and cars. Burning forests. Plankton dying. Methane from the ground, cows and Taco Bells.
