I'm trying to point out your units are parts per million. The full atmosphere is one million units. If 80 units take up 5 inches of vertical computer screen space, one million units would take 1 mile up of screen space. If you were to scale the atmosphere content to fit on your screen you would not see that CO2 content even exists. It's a very small player in the atmosphere, and the delta from 200 years ago is even smaller.
Through the use of very precise laboratory instruments taking millions of readings over many years and analyzing them with statistics scientists can barely detect that human CO2 generation exists.

The use of very precise instruments and observations of the change in both the 14C/12C ratio and the 13C/12C ratio (in seawater and tree rings and carbonate sediments and ice cores) indicate that the increase in atmospheric CO2 concentrations since the mid-1800s is due primarily to fossil fuel combustion for energy production.
