Climate change, biochar and community action: An exchange of letters

When plants grow, they take up carbon dioxide from the atmosphere. When the plants die, the carbon is released back into the atmosphere. However, if the plant mass is converted to charcoal, the carbon that was in the plant can be locked into the soil instead of being released into the atmosphere. Charcoal is made by heating biomass (plant and animal material) in the absence of oxygen. The fumes that are driven off can be fed back to fuel the furnace, and can also be captured to produce high octane fuel. The heat produced can be used to generate electricity.
