Episode notes
Mr. Iwane's Climate Change Struggle
- Mr. Iwane, a Cameroonian coffee farmer, faces declining crop yields due to erratic rainfall caused by climate change.
- Despite not being responsible for the climate crisis, Mr. Iwane's livelihood is directly impacted.
Carbon Capture and Stabilization
- Plants capture CO2, but it's released back into the atmosphere during decomposition or burning.
- Stabilizing the carbon in crop leftovers can remove CO2 and combat climate change.
Biochar: A Long-Term Carbon Sink
- Biochar, a stable form of carbon from pyrolysis, can remain in soil for centuries, effectively removing CO2.
- This makes it a viable long-term carbon removal solution.
