Thanks for the added material. It seems we understand the differences well, so
I will keep this short.

Some years ago I calculated how much energy it would take to convert
100 ppm of CO2 into synthetic oil which could be stored in old oil
fields safely for millions of years.
100 ppm of CO2 would be 470 cubic km of the stuff. It's what humans
added to the atmosphere since ~1960.
