Re: Forests: Carbon sequestration, biomass energy, or both? - New paper #carbonsequestration

How well do these numbers fit with your calculations (in your message below)
“Every year, plants convert 4,500 EJ of solar energy and 120 Giga Tonnes of carbon [= 439 Gt CO2] from the atmosphere into [ ~240 Gt of new] biomass – eight times as much as the global energy need.” (https://worldbioenergy.org/uploads/Factsheet_Biomass%20potential.pdf , 2016). That same document identified the global composition of annual biomass supply in 2012 to be 56 EJ of biomass energy [about 29 Gt of biomass], with an expected near- tripling to 150 EJ by 2035 [~85 Gt of biomass].
The above is from the WBA (World Bioenergy Association) in 2016.

Hi David, research I did in 2007 claimed these figures, - "Approximately 100 billion tons of carbon circulates between the atmosphere and the approximately 750 billion ton reservoir in Land plants” .
Later I came across a claim that it was 110 billion tons, so I thought well, that’s in the ball park.
So that gives us a pretty good margin, - we don’t have to pyrolize every skerrick.
Last I could bear to look we are throwing about 15 billion tons into the atmosphere every year, but of course not at this moment thanks to Coronavirus.
Nothing like getting back to Base Principles Eh.
