What is the most important meeting to pay attention to? Perhaps it is Barack Obama's townhall ... or perhaps not.
There are a lot of valuable and exciting conferences out there.
It is an understatement to say that the energy and environmental domains are "hot" and that you could spend your life solely running from conference to conference while only getting a taste of valuable meetings. From wave energy meetings in Sweden to water-less toilet sessions in Finland to Energy Summits hosted by Harry Reid in the Las Vegas heat, there are a lot of valuable and important choices out there. As with looking toward better sanitation options in Finland, some potentially critical sessions go on with little media (and thus little popular) attention. Right now, Boulder, Colorado, is hosting one such meeting: North American Biochar 2009.
Right now, humanity is engaged in a massively reckless geoengineering experiment, pumping huge amounts of carbon dioxide and other GHGs while continuing to pave the planet black and otherwise modify the humanity's habitat with little understanding (or regard) for the havoc that we are and could be creating. In response to this, we have the serious movements to find paths to reduce emissions (whether through efficiency or clean energy or ...) but there are also increasing calls for looking toward geoengineering (both from the thoughtful to the inane).
When it comes to this arena, there are some basic principles that should guide on thinking on geoengineering. In short, we should seek paths that support multiple goods (saving money, improving life conditions, helping reverse global warming) rather than costly paths that create more risks and uncertainties and whose pursuit seem to large costs with stovepiped (and uncertain) benefits.
The core principle should be: win-win-win. A proposal that, in a systems of systems effort, provides multiple wins and does not solely address temperature. Thus, a proposal that offers real potential for improving economy, reducing carbon, and contributing to reduced temperature (both directly, somehow, and indirectly through reduced carbon loads or carbon capture) would seem to merit greater prioritization than high-cost efforts that would solely impact "temperature" but not impact (or worsen) the carbon load equation.
The first, when it comes to the built environment, is High-Albedo (White) Roofing (and other human infrastructure): Secretary of Energy Steven Chu has brought attention to the great win-win-win potential here. Building owners would see direct financial savings, the urban heat island would cool (leading to more energy savings as the ambient temperature falls), our cities would be more comfortable, and we would reduce global warming directly (reflecting more solar radiation to space) and indirectly (the multiplicative energy savings). What are we waiting for? Let's get to it ... make this national building code for, at least, flat-roofed buildings: yesterday!
When it comes to the agricultural space, we turn to bio-char/agri-char and why Boulder might have the most important meeting in America. Very simply, we have the potential for a carbon-negative fuel that will, over time, also foster improve fertility in soil. Very simply, gasification of biomass can be combined with agricultural practices to create energy, have the waste plowed back into the soil to improve fertility (while reducing fertilizer requirements), and have some of the carbon from each of these cycles captured in the soil.
"[T]he great advantage of biochar is the fact that the technique can be applied world-wide on agricultual soils, and even by rural communities in the developing world because it is relatively low tech."
The conference, going on right now in Boulder, pulls together many of the globe's top experts in this domain: from understanding soil dynamics to experts on biomass power generation associated with biochar to environmental historians to technologists with innovative paths forward to policy experts who work to provide pathways to make reality of biochar's promise.
This is a highly promising arena that has gotten a little attention, but not enough and certainly not enough resources. If Secretary of Energy Chu has become a visible spokesman for White Roofing, maybe another Administration official will do the same for bio-char:
The keynote speakers for the conference will be Secretary of Agriculture Tom Vilsack and Dr. Susan Solomon, Senior Scientist, National Oceanic and Atmospheric Administration
Source note: Beneath the radar scope of most, there is a lot of work going on in biochar/terra preta. May links with additional information end of discussion here
Some videos, serious and seriously amusing but serious.

Steven Chu on White roofing
Highly recommend taking the time to watch Steven Chu on The Daily Show where, among other things, he spoke of white roofing.
