Trees dying and not decomposing is how we got all that coal that we're now turning back to CO2.

Trees dying and not decomposing is how we got all that coal that we're now turning back to CO2.
- cmrdporcupine 5y agoIt's also how we got all the carbon in our top soils. A 6 inch or more covering of carbon (mixed with minerals etc) covering huge parts of the earth's surface. Planting trees, harvesting them, and turning them by pyrolysis into biochar/charcoal and then burying it can partially restore these soils and sequester carbon at the same time.
- adrianN 5y agoYep, but it is a nontrivial amount of work to produce approximately as much biochar as we have burnt coal.
- cmrdporcupine 5y agoOh, absolutely. It would take generations. But taking forestry waste and turning it into a soil amendment is a worthwhile endeavour even from the POV of improving food production.
