Fine ash and carbon would have circulated high in the atmosphere cutting out the sun and killing huge areas of plant and animal life as well as dramatically changing rainfall patterns and temperatures over much of the earth's surface. Rapid kill-off of photosynthesising plant life = change in CO2/O2 balance.

It would seem that harvesting carbon for energy reduces the amount being lost to subduction . Is there any way to estimate past carbon deposits size pre-subduction compared to today’s ?

Perhaps something like the "decelnization of salty sea water" which is going to become and even "hotter" issue. The planet appears to be running out of "drink-able" water, combined with current "fracking" there will soon be even less. The thoughts come from "Chemical Plants" wherein they create, but also breakdown therefore creating new usable. What would happen if Carbon Dioxide were “broken down” from it’s composition?
