Episode notes
Amazon As Continental Air Conditioner
- The Amazon acts like a continental air conditioner by recycling huge volumes of water vapor.
- This 'flying rivers' system stabilizes rainfall, monsoons and agriculture across much of South America.
Huge Carbon Reservoir At Risk
- The Amazon stores an enormous amount of carbon equivalent to over a decade of global fossil fuel emissions.
- Losing that carbon would risk runaway warming far worse than today's climate change.
Tipping Point Near For Savannization
- Scientists estimate a tipping point when 20–25% of the Amazon is deforested, triggering savannization.
- Parts of the southeast are already a net carbon source, suggesting the tipping point is near or beginning.
