I think your math is off.

Tomayto, tomahto... Your "by volume" theory really has no point, whether you cite "total" GHG or or "total" gases overall. The point is the total thermal signature of the uptick, and the genesis of the uptick.

C02 by itself contributes somewhere between 9-25-ish% of the
greenhouse effect. (Per your cohort Shek, and many other public sources)
Current levels of CO2 are at 384 ppm, or .0384%; up about 100 ppm from the late 50's - early 60's. (both facts well documented)
Anthro sources of the CO2 can be directly tied to the uptick. (Per direct carbon ratio studies)
Your number does not work out very well in these well established numbers.
