- -01 Beating Climate Change Will Require Massive Government Coordination (Grist.org)
"One of my recurring obsessions over the years has been the enormous difference between reducing carbon emissions and reducing carbon emissions enough. There are thousands of ways to reduce emissions relative to a business-as-usual baseline, many of which are relatively painless. But reducing emissions enough to limit temperature rise to 2 degrees Celsius — the agreed-upon international target — is another matter entirely. Plenty of policies and strategies can achieve the former but not the latter."
"That’s why, to my mind, some of the most important work in the world is being done at the Deep Decarbonization Pathway Project (DDPP). Convened by the Sustainable Development Solutions Network and the Institute for Sustainable Development and International Relations, it consists of 15 research teams, one for each high-emitting country, each charged with developing concrete, detailed pathways by which its respective country could reduce emissions enough to meet the 2C goal." 11-14

"Engineers envision that long plastic tubes, called photobioreactors, be integrated into building designs or retrofitted onto existing skyscrapers. Algae would grow from pumped-in carbon dioxide and sunlight and be harvested for use either as a liquid fuel to run in a combined heat-and-power unit or turned into biochar, or charcoal used as a soil conditioner that also sequesters carbon from the air." 09-09

- -Climate Change: What We Can Do (Evaluation and Development Institute)
"Earth's climate became very stable 10,000 years ago, allowing for agriculture for the first time. Our stable climate arose from a balance of three ingredients:
-Greenhouse gases
-Ocean currents and
-Polar ice
Greenhouse gases provided a stable temperature to allow ocean currents to mix heat and cold around the globe and to maintain a relatively constant amount of polar ice.
We now have 1/3 more CO2 in the air than we had only 150 years ago--and CO2 stays in the atmosphere for hundreds of years. The extra carbon keeps more heat in the air. The extra heat is absorbed by polar ice, soil, and the oceans. The ice over the Arctic Ocean is expected to be gone during summers within 5-10 years. Instead of ice over the Arctic Ocean reflecting heat, the Arctic Ocean will absorb heat. This will slow the ocean currents even more--they already are slowing because of the change in climate.
When the ocean currents stop and the Arctic ice melts, we will have a climate catastrophe that can be expected to last thousands of years. Permafrost in Russia and other regions will melt, releasing gigantic amounts of carbon and methane stored in the soil. The release will trigger even more extreme climate."
"Only one cost-effective solution has been found for quickly reducing the carbon in the air:"
"Each year we must convert enough biomass (organic waste) into biochar (charcoal) to extract at least 7 gigatons of carbon from the air and place it in our soils." 08-09
- -One Last Chance to Save Mankind (TreeHugger.com)
"For those that don’t know who James Lovelock is here’s the one sentence bio: Originator of the Gaia hypothesis, chemist, did work on atmospheric chlorofluorocarbons which eventually led them from being banned, advocate of nuclear power. Which is to say, that when James Lovelock says humanity only has one chance left not to get annihilated by the effects of climate change in the 21st century, it’s worth shutting up and listening to what the man says." 10-10
- -Study: Biochar Can Provide Substantial CO2 Reduction (Tri-CityHerald.com)
"The most comprehensive analysis yet of the worldwide potential of biochar -- a charcoal-like substance -- shows it could offset up to 1.8 billion metric tons annually of the world's human-caused greenhouse gas emissions, according to a new study."
"The study found the maximum total offset amounts to 12 percent of the current 15.4 billion metric tons of greenhouse gas emissions that human activity adds to the atmosphere each year." 10-10

- Biochar for for Removing Phosphate from Water (WaterandWastewater.com)
"In the study, researchers started by collecting solid residues left after beet tailings were fermented in a device called an anaerobic digester, which yields methane gas. The material was baked at about 1,100 degrees Fahrenheit to make biochar."
"The biochar was added to a water-and-phosphate solution and mixed for 24 hours. It removed about three-fourths of the phosphate, much better results than researchers obtained with other compounds, including commercial water-treatment materials. The phosphate-laden biochar can be applied directly to soils as a slow-release fertilizer." 03-12

- How Much Biochar Will Be Needed to Return to Pre-Industrial Levels of Carbon? (TerraPetra.BioenergyLists.org)
"The Earth’s surface area is 51 gigahectares (nice unit!) of which 1.36 gHa are arable (by George M’s figure) - that’s 2.7% of the total. So:"
"If all the 'excess' carbon dioxide in the atmosphere were converted into carbon and spread across all the earth’s arable lands, there would be 17kg of charcoal per square metre, in a layer 8cm thick."
"That’s not an unfeasible notion. The Gardening with Biochar FAQ mentions biochar application rates of around 5kg/m2." 08-09
- Stability of Biochar (UCSUSA.org)
"Major et al (2010) produced biochar and applied it to soils in a Colombian savanna, thenmeasured the amount of the biochar carbon respired as CO2 from the soil and the amount percolating through the soil. Two years after the biochar addition, their measurements indicated that up to 3% of the biochar had been respired as CO2, but they could not account for 20-50% of the biochar. Presumably it washed off the fields during intense rainfall, but Major et al. had no direct measurements of biochar in runoff. Assuming that none of the “missing” biochar carbon was respired and converted to CO2 after leaving the site where the investigators were measuring soil CO2 emissions, the authors calculated a mean residence time for thebiochar of approximately 600 years."
"Haefele et al. (2011) produced biochar from rice husks and applied it to rice cropping systems in the Philippines and Thailand. At one site they measured CO2 emissions from the soil immediately after application and again two years later. At all sites they measured biochar carbon in the soil after application and two years later. Where Haefele et al. measured soil respiration they found no change between the two time points, and, more significantly given the limited sampling of CO2 emissions, found no change in the amount of biochar in the soil. The authors conclude that 'realistic residence times might be in the range of thousands of years….' ” 01-17
