Bhaskar et al You are mostly correct below, but leaving out the fact that the “8 Billion tons of Carbon consumption per year” is nearly balanced by the subsequent return of that carbon as the biomass rots or is consumed by “critters”. The net annual change is a small part of that 8 Gt C/yr.
My answer for your last question to John below: he is almost certainly talking of a net value - but much larger than 2 Gt C/yr. - close to your value of 10 Gt C/yr. I am about to send in my own analysis of John’s interesting chart. I am saying there, in part, that ocean biomass can be helpful - because growth rates are so large - and presumably can be captured in the 2030 time frame that is central to John’s scenario. Of course I see much of that ocean biomass ending up in soils - providing the best economic returns (including carbon neutral energy values as well) - for centuries/millenia (as with terra preta soils).
