8.  I haven't had time to get into this - but we on  "Terrapreta" can help 
Hansen by adding more substantiation on how much can be  done.  Hansen is a 
cautious author - so I suspect the above may be on the  low side.  He is not 
mentioning growth of bacteria and fungus , nor the  added above-ground biomass that 
must occur.  Also no mention of  agricultural NOx reduction. Anyone have 
alternative numbers?  And the  costs to do this?


 
Also no mention of other direct effects;
 
10X N2O Reductions, Methane reductions, or  water  savings, 
 
and in-direct effects;
 
Water shed pollution abatement ,
 
With a proper total accounting, of all co-benefits, I'll bet that every ton  
of Char/Carbon sequestered is truly worth at least two tons, but that is  
sheer speculation, each soil type will be different. I have no idea of the  
baseline volume of N2O soil emissions of the average agricultural  acre.  
 
 
 
" help Hansen - who I now view as likely to be our most  effective spokesperso
n."
 
I sent several posts to Hansen over the last two years, and an  old high 
school friend who does ocean rise work at EPA. He , like Hansen has  during this 
administration had restrictions placed on direct contact with the  media.
 
Great to see that Hansen is  talking up Biochar  now!
