I just posted the following comment to the review of "Hell and High Water" on Gristmill:
I'm halfway through the book, and I've come to the conclusion that it's the very best general-interest GW book I've read so far. The tone is strong and uncompromising, but the book itself isn't depressing. What
is depressing is watching the American administration stick its collective head in the sand (or somewhere more scatological, if you prefer).
My major concern is in the imminent convergence of Climate Change, Peak Oil and Food Scarcity. Researching those three aspects of the Global Problematique, keeping an eye out for ways they intersect and amplify each other, as well as how solutions to one may be incompatible with (or even prevent) solutions to the others - now
that's depressing.
I'm even thinking of putting together a two-book package on this convergence to give to people who Need To Know. It would consist of Hell and High Water and Richard Heinberg's "The Party's Over" - one of the better general books on Peak Oil.
Anyhow, on to charcoal fertilizer. I recently had my eyes opened to the general subject of
Terra Preta do Indio in the Amazon. This led me to the discovery of the commercialization of the idea by a company called
Eprida, and also to the academic work of
Johannes Lehmann.
This research points the way to a very low-level technology that has mind-boggling promise: it sequesters carbon, it enhances soil fertility, and it can produce biofuels - both directly by growing fuel crops and indirectly during the charcoal-making process. As a result it addresses in one mechanism the three main converging crises: liquid fuels, CO2 emissions and imminent food scarcity.
It's also one of the few mitigation proposals that might actually scale up enough to do some good. In fact the scalability seems to be extremely good, as reported in
this article:
Claims for biochar's capacity to capture carbon sound almost audacious. Johannes Lehmann, soil scientist and author of Amazonian Dark Earths: Origin, Properties, Management, believes that a strategy combining biochar with biofuels could ultimately offset 9.5 billion tons of carbon per year-an amount equal to the total current fossil fuel emissions!
As a result, I'm convinced that this technology deserves mention, an possibly even pride of place, in analyses such as Dr. Romm's. I have yet to see it mentioned in any general-interest overview of the topic, and I believe this is an egregious oversight. It's certainly as doable as a million wind turbines, less technologically problematic than CO2 sequestration in old gas fields, and much more politically acceptable than 700 nukes.
