Sigma Series — Biochar, Environmental Superstar

Tuesday, January 9, 2018

This lecture will describe biochar, its history and its virtues, and also describe how it can be made and used simply by almost anyone. Most approaches to the global warming problem concentrate on reducing the rate at with greenhouse gases are added to the atmosphere with the ultimate hope of moving to a “carbon free” future in which we are no longer adding them at all. But these solutions cannot undo the damage that has been done by 300 years of removing carbon from geological sequestration to cycle through the atmosphere, biosphere, and oceans. To reverse this damage, carbon must be withdrawn from the cycle and sequestered in an inert state for hundreds or thousands of years. Doris Hamill is a scientist with degrees in physics and biophysics who has spent her career managing technology development.
