Charcoal from Comets, Asteroids and Wildfires
Tom Miles, May 28, 2007

There is speculation that pockets of charcoal that resulted in enriched soil came variously from comets and asteroids and resulting wildfires, as well as intentional burning. The latest comet event has been reported as 12,900 years ago in North America. See Science Daily:
Did A Comet Hit Great Lakes Region, Fragment Human Populations, 12,900 Years Ago? May 23, 2007

and National Geographic News:
Comet Wiped Out Early North American Culture, Animals, Study Says May 23,2007

Potential extraterrestrial causes of terra preta formation are discussed in the literature from Cornell University and elsewhere. It has also been debated on the Hypography Science Forum.

Simpler Way To Counter Global Warming Explained: Lock Up Carbon In Soil And Use Bioenergy Exhaust Gases For Energy
Science Daily News, May 12, 2007

Writing in the journal Nature, a Cornell biogeochemist describes an economical and efficient way to help offset global warming: Pull carbon dioxide out of the atmosphere by charring, or partially burning, trees, grasses or crop residues without the use of oxygen.


Commentary: A Handful of Carbon
Johannes Lehmann in Nature Magazine, Vol 447, 10 May 2007

Locking carbon up in soil makes more sense than storing it in plants and trees that eventually decompose, argues Johannes Lehmann. Can this idea work on a large scale?
