Here is a snippet from the larger story...

*And then there is biochar -- the gas and charcoal that arises from a
process of burning any form of biomass with the absence of oxygen, called
pyrolysis. *

* Charcoal is one of the most stable forms of carbon known to man. It is
also an excellent soil fertilizer. *

* Biochar in its charcoal form is seen by many, including Flannery, as one
of the single most important carbon sequesters in the world -- perhaps even
better than reforestation. *

* Put simply, reforested trees can be cut down, but once charcoal is plowed
in the soil, it's there to stay for up to a thousand years. *
