Mongabay: The first comprehensive assessment of the climate cooling potential of different geoengineering schemes has been conducted by researchers at the University of East Anglia (UEA). The results are published in the journal Atmospheric Chemistry and Physics Discussions Among the findings, according to a statement from UEA:Enhancing carbon sinks will take nearly 100 years to bring atmospheric carbon dioxide levels back to pre-industrial levels and will require sharp cuts in emissions.
Stratospheric aerosol injections and sunshades in space — a concept supported by Paul J. Crutzen, winner of the 1995 Nobel Prize in Chemistry for his work on the hole in the ozone layer — have "by far the greatest potential to cool the climate by 2050" but carry the greatest risk.
Adding phosphorous to the ocean via existing activities may have greater long-term carbon sequestration potential than iron or nitrogen fertilization schemes.
Sequestering carbon by planting forests and as 'bio-char' — charcoal added back to the soil — have greater short-term cooling potential than ocean fertilization. Bio-char also offers to potential to boost soil productivity for agriculture.
Increasing the reflectivity of urban areas could reduce urban heat islands but will have minimal global effect. The same goes for schemes involving ocean pipes and stimulating biologically-driven increases in cloud reflectivity.
The beneficial effects of some geo-engineering schemes have been over-estimated and mis-calculated in previous calculations….

Biochar, the modern version of an ancient Amazonian agricultural practice called Terra Preta (black earth), is gaining widespread credibility as a way to address world hunger, climate change, rural poverty, deforestation, and energy shortages… SIMULTANEOUSLY!
The IBI Announces Success in Having Biochar Considered as a Climate Change Mitigation and Adaptation Tool;
POZNAN, Poland, December 10, 2008 - The International Biochar Initiative (IBI) announces that the United Nations Convention to Combat Desertification (UNCCD) has submitted a proposal to include biochar as a mitigation and adaptation technology to be considered in the post-2012-Copenhagen agenda of the UN Framework Convention on Climate Change (UNFCCC). A copy of the proposal is posted on the IBI website at
The International Biochar Initiative (IBI).
Modern Pyrolysis of biomass is a process for Carbon Negative Bio fuels, massive Carbon sequestration,10X Lower Methane & N2O soil emissions, and 3X Fertility Too.
Every 1 ton of Biomass yields 1/3 ton Charcoal for soil Sequestration, Bio-Gas & Bio-oil fuels, so is a totally virtuous, carbon negative energy cycle.
Charles Mann ("1491") in the Sept. National Geographic has a wonderful soils article which places Terra Preta / Biochar soils center stage.
Please put this (soil) bug in your colleague's ears. These issues need to gain traction among all the various disciplines who have an iron in this fire.
http://ngm.nationalgeographic.com/2008/09/soil/mann-text
I also have been corresponding with Michael Pollan ( NYT Food Columnist, Author ) to do a follow up story.
Since the NGM cover reads "WHERE FOOD BEGINS" , I thought this would be right down his alley and focus more attention on Mann's work.
It's what Mann hasn't covered that I thought should interest any writer as a follow up article;

The many new university programs & field studies, in temperate soils; Cornell, ISU, U of H, U of GA, Virginia Tech, JMU, New Zealand and Australia.
Glomalin's role in soil tilth, fertility & basis for the soil food web in Terra Preta soils.
Given the current "Crisis" atmosphere concerning energy, soil sustainability, food vs. Biofuels, and Climate Change what other subject addresses them all?
This is a Nano technology for the soil that represents the most comprehensive, low cost, and productive approach to long term stewardship and sustainability.
Carbon to the Soil, the only ubiquitous and economic place to put it.
In a recent National Public Radio interview, Michael Pollan talks about how he was approached by a Democratic party staffer about his New York Times article, The "Farmer & Chief", an open letter to the next president concerning U.S. agriculture/energy policy. The staffer wanted Pollan to summarize the article into a page or two to get it into the hands of Barack Obama. Pollan declined, saying that if he could have said everything that needed to be said in two pages, he wouldn't have written 8000 words.
Michael Pollan is well briefed about Biochar technology, but did not include it in his "Farmer & Chief" article to President Obama, (Which he did read & cited in a speech) but I'm sure Biochar will be his 8001th word to him.

Total CO2 Equivalence:
Once a commercial bagged soil amendment product, every suburban household can do it,
The label can tell them of their contribution, a 40# bag = 150# CO2 = 160 bags / year to cover my personal CO2 emissions. ( 20,000 #/yr , 1/2 Average )
http://www.epa.gov/climatechange/emissions/ind_calculator.html
But that is just the Carbon!
I have yet to find a total CO2 equivalent number taking consideration against some average field N2O & CH4 emissions. The New Zealand work shows 10X reductions.If biochar proves to be effective at reducing nutrient run-off from agricultural soils, then there will accordingly be a reduction in downstream N2O emissions.
This ACS study implicates soil structure as main connection to N2O soil emissions;

Most all this work corroborates char soil dynamics we have seen so far . The soil GHG emissions work showing increased CO2 , also speculates that this CO2 has to get through the hungry plants above before becoming a GHG.
The SOM, MYC& Microbes, N2O (soil structure), CH4 , nutrient holding , Nitrogen shock, humic compound conditioning, absorbing of herbicides all pretty much what we expected to hear.
Company News & EU Certification
Below is an important hurtle that 3R AGROCARBON has overcome in certification in the EU. Given that their standards are set much higher than even organic certification in the US, this work should smooth any bureaucratic hurtles we may face.
EU Permit Authority - 4 years tests
Subject: Fwd: [biochar] Re: GOOD NEWS: EU Permit Authority - 4 years tests successfully completed
Doses: 400 kg / ha – 1000 kg / ha at different horticultural cultivars
Plant height Increase 141 % versus control
Picking yield Increase 630 % versus control
Picking fruit Increase 650 % versus control
Total yield Increase 202 % versus control
Total piece of fruit Increase 171 % versus control
Fruit weight Increase 118 % versus control
There is list of the additional beneficial effects of the 3R FORMULATED BIOCHAREU DOSSIER for permit administration and summary of the results from 4 different Authorities who executed different test programme is under construction
I suggest these independent and accredited EU relevant Authority permit field tests results will support the further development of the biochar application systems on international level, and providing case evidence, that properly made and formulated (plant and/or animal biomass based) biochars can meet the modern environmental - agricultural - human health inspection standards and norm, while supporting the knowledge based economical development.
We work further on to expand not only in the EU but in the USA as well. My Cincinnati large scale carbonization project is progressing, hopefully the first industrial scale 3R clean coal - carbon plant will be ready in 2009.

U.S. Department of Agriculture to Evaluate CQuest™ Biochar
Non-Funded Cooperative Agreement Signed
The objective of the biochar research is to quantify the effects of amending soils with CQuest™ Biochar on crop productivity, soil quality, carbon sequestration and water quality. Field trials will involve incorporation of biochar in replicated field plots and on-farm strip trials with monitoring of crop yields, soil quality, water quality, emissions of greenhouse gasses, and soil carbon sequestration. Laboratory studies will involve amending soils with biochar and quantifying changes in soil quality and microbial activity during incubations.
Biochar will be shipped from Dynamotive's West Lorne facility to Agricultural Research Service (ARS) locations in Iowa, South Carolina, Idaho, Washington, and other ARS locations. Initial results are expected during the 2009 growing season.

Hola, Interesante, no va a continuar con este artŠ½culo?
Lovely sharp post. Never thought that it was this easy. Extolment to you!.
Thanks Anonyno,
I have never been granted Extolments before.
Biomass should never be just burnt, instead it should be fractionated to it's high value uses.
Biochar systems achieve this, to fill in gaps and hopefully expand your story & research , particularly concerning Christoph Steiner's new work with Biochar and NH3 conservation in composting systems.
Recent NATURE STUDY;
Sustainable bio char to mitigate global climate change
http://www.nature.com/ncomms/journal/v1/n5/full/ncomms1053.html
Not talked about in this otherwise comprehensive study are the climate and whole ecological implications of new , higher value, applications of chars.
First,
the in situ remediation of a vast variety of toxic agents in soils and sediments.

Second,
The uses as a feed ration for livestock to reduce GHG emissions and increase disease resistance.
Third,
Recent work by C. Steiner, at U of GA, showing a 52% reduction of NH3 loss when char is used as a composting accelerator. This will have profound value added consequences for the commercial composting industry by reduction of their GHG emissions and the sale of compost as a nitrogen fertilizer.
Since we have filled the air , filling the seas to full, Soil is the Only Beneficial place left.
Carbon to the Soil, the only ubiquitous and economic place to put it.
Thanks for your efforts.
