Soil carbon farming can remove the 40% overshoot of today’s excess atmospheric CO2 and stabilize levels for today’s climate, but in the narrowly shrinking time window for effective action this can be achieved with current carbon farming methods in decades only if both quantity and quality (lifetime) of soil carbon removal are increased greatly above current (land and carbon degenerative) practices.
New calculations show that there is critical need to focus on storing carbon in the two soil types with the most long lived carbon, biochar that can be produced and applied in any soil, and restoring wetlands, especially marine wetlands like mangroves, salt marshes, and sea grasses. Large-scale, long-term carbon sequestration efforts such as the Commonwealth Secretariat’s proposal for Regenerative Development to Reverse Climate Change are critically needed.
The new soil carbon drawdown information was presented for the first time at the World Soil Day event in Harvard Square, Dec 5 2016, sponsored by Soil4Climate Green Cambridge and the Soil Carbon Alliance
This talk follows up on presentations two weeks before at the Conference on Marine Biodiversity and Climate Change, held at Harvard by Biodiversity for a Livable Climate, which showed that oceans could become significant carbon sinks only by turning them into dead zones. but that new Biorock methods produce effective restoration of marine ecosystem services by rapidly restoring coral reefs, oyster reefs, sea grasses, salt marshes, fisheries habitat, and severely eroded beaches.
