The ~9800 years preceding the last 200 years showed a gentle increase from about 265ppm to ~280ppm.

Around 1912, atmospheric CO2 levels breached the 300 ppm threshold for the first time in at least 2.1 million years. In the last few years we've broken through 400ppm!

Dry air is still composed of roughly 78.09% nitrogen, 20.95% oxygen, 0.93% argon, and 0.04% carbon dioxide...messing with the hundreths of decimal points is obviously no big deal because we have so much air...
I might be missing something in this post.

I had said I believe the climate dispute is over what kind of impacts the .01% additional atmospheric CO2 is having (if any) on our environment, and you’re response is that atmospheric CO2 has risen 100 ppm?

I don’t understand what point you were trying to make.
