Amazon Rainforest (Carbon Sink)
conceptMoney & Finance
The Amazon is close to a point of no return where it stops being a rainforest and turns into dry grassland — and that would speed up climate breakdown worldwide.
Who they are
The Amazon rainforest, the vast carbon-storing forest, treated here as a make-or-break climate system.
What they do
The engine tracks how close it is to a tipping point where it can't recover.
How it works
It's already 17-18% deforested; scientists (Nobre/Lovejoy) warn that 20-25% triggers an irreversible flip to savanna because the forest makes its own rain. A record 2024 drought lost 2.78 million hectares, 60% to fire; cattle ranching drives 80% of clearing, pushed by Chinese demand for soy and protein — and the clearing continues no matter which government is in power.
Why it matters
If the Amazon flips, a major planetary carbon sponge is lost and global pollution overshoot accelerates sharply.
The engine's record — word for word
17-18% deforested. Tipping point at 20-25% triggers irreversible phase transition from rainforest to savanna (Nobre/Lovejoy). Generates own rainfall via moisture recycling. 2024 record drought: 2.78M hectares lost, 60% from fire. Degradation surged 163% while clear-cutting fell 11%. Cattle ranching 80% of clearing, driven by Chinese soy/protein demand. Jiang test: extraction continues regardless of government ideology. If Amazon flips, BAU2 pollution overshoot accelerates radically.
