Episode notes
Amazon's Carbon Role Shift
- The Amazon rainforest has shifted from being a carbon sink to a carbon source due to recent droughts and biomass fires.
- This shift may be temporary but highlights the increasing vulnerability of the forest to climate change.
Early Satellite Deforestation Work
- Brazil's deforestation monitoring started with 200+ satellite images analyzed manually on transparent paper.
- Transitioning to digital methods enabled consistent and detailed tracking of deforestation trends over decades.
Advancing Biomass Monitoring
- Use new biomass-detecting satellites and controlled CO2 injection experiments to better understand forest carbon changes.
- Combine satellite data with on-the-ground measurements for accurate and ongoing forest biomass assessment.
