[Terrapreta] CO2 in the oceans

[teelws at jmu.edu]

Kevin, David and All,

Belief and trust in science are generally founded on following a rigorous set of methods designed to eliminate bias and get at an empirical evaluation of a particular phenomenon.  This rigor is then judged by a peer group of scientists in a refereed system that attempts with vigor to weed out junk science and only allow to be published the material that passes muster.  James Hansen is one scientist who has done this with regularity.  His "opinions" are based on considered judgment based on rigorous scientific principles.  Thus the "trust" has a foundation in broad community assessment based upon the principle of doubt.  Scientists are skeptics at their core.  Thus when the community reaches approximate consensus it ought not be ignored or rejected.

Having read Hanson's work, and the work of such climate change skeptics as Patrick Michaels, I am convince that James Hanson and the IPCC do much better work.  Michaels and the climate skeptics generally rely on older data, sometimes vetted, sometimes not, that now lacks scientific community credibility.  For us readers of terrapreta this credibility is very important.  We need to know if biochar can improve soil quality and sequester carbon.  Drs. Lehmann and Steiner have the kind of credibility in the science community that Hanson has, which is why we tend to go back to their work as the foundation for our own efforts to prove the efficacy of biochar in other soils.  Rejecting the scientific community's general premise puts us in danger of looking ridiculous and finding ourselves trapped by unintended consequences.  We do need to exercise caution and not create more problems than we are attempting to solve.

On the other hand, accepting the fact that Hanson is correct, we need to move fast.  The planet shows strong signs of ill-health and we are the likely cause.  Terrapreta is one arrow in our quiver that looks good, especially since it improves poor quality soils (I am not saying yet that it is beneficial in high quality, high organic matter soils) and has potential to sequester carbon.  Our task, at least as I see it, is to make sure that terrapreta works, is produced in a manner that "does not harm" and can be replicated widely by people in a diverse number of climates, regions, and economic conditions.  

My own minor experimenting indicates that biochar I made from waste wood in a wood stove, improves germination and early growth rates in swiss chard, but some design flaws in the experiment made it unpublishable.  I plan to improve the design, based in part on what I have read on this list and in published materials, and see if these initial observations are valid.  Good science will be the foundation of our success.  Therefore it is imperative that we have a good understanding of what good science is.  Hanson, in my judgment, is a good scientist.
