[Terrapreta] Catalyst: Carbon Bigfoot

[Sean K. Barry]

Hi Kevin,

Kevin says:

You raise an excellent point: Char is being used as a carbon neutral 
fuel, rather than for TP.

If GW was not being caused by GHG's, and if char was not being used to 
reduce GHG's, then more char would be available for TP, with all the 
benefits you list below.

You missed my excellent point!  Using charcoal as a "carbon neutral" fuel is NOT the best way to combat Global Warming caused from increased concentrations of GHG.  If charcoal is used in the formation of Terra Preta soil, then it becomes "carbon negative", instead of being just "carbon neutral" fuel.  Charcoal made from plants that take CO2 out of the atmosphere when they were growing, once put into soil, will sequester that CO2 for 500 to 10,000 years or more.  That is undeniably a better form of carbon sequestration than any carbon stored in living plants.  TP formation can actually "mine" CO2 from the atmosphere and sequester it, darn near permanently.  Burning charcoal only prevents the release of more CO2 from burning fossil fuels.  Burning charcoal from biomass is only "carbon neutral" because it recycles atmospheric carbon (versus adding fossil carbon to the atmosphere).  It will not reduce atmospheric carbon concentrations to just burn more charcoal and burn less fossil fuels.

I think burning fossil carbon should be made illegal or heavily fined or both.  I think we should make charcoal from renewable fresh (annual growth) biomass.  We need to put charcoal into the soil and demonstrate the agricultural benefits.  I think the charcoal amendments to soil should be done Terra Preta style, with other biomass amendments (compost, natural fertilizers), microorganism inoculants, and all the working permaculture practices you can throw at it.

We have to quit monkey diddling around and debating whether Global Warming is human caused or not.  We have to rethink whether "The American Way of Life is Not Negotiable" or whether it is and "adaptation" to imminent GW will force greedy, self serving behaviors to die out.  Making Terra Preta soils is a reasonable attempt to do things that will BOTH help humans adapt to imminent Global Warming Climate Changes and will make an effective mitigation strategy against rising GHG concentrations.  

Regards,

SKB

  Dear Sean

  You raise an excellent point: Char is being used as a carbon neutral 
  fuel, rather than for TP.

  If GW was not being caused by GHG's, and if char was not being used to 
  reduce GHG's, then more char would be available for TP, with all the 
  benefits you list below.

  If we hang the future of TP on funding from Carbon Credits, TP would be 
  dealt a serious blow, if Carbon Credits were not forthcoming.

  On the other hand, if we develop TP in a way that it can be successful 
  on its own merits for promoting more effective agriculture, then Carbon 
  Credits would be a massive windfall, and an enormous boost to TP use.

  What do you think we should be doing to maximize the early acceptance 
  and widespread use of char for TP?

  Best wishes,

  Kevin
