The Spin
Narrative A
The Amazon's tipping point is a huge issue for our global climate emergency. This study shows that the rainforest is on its way to being a much-feared net emitter of CO2 by 2050. There's still a window to take action, but we're running out of precious time.
Narrative B
This doesn't merit the hysteria. Researchers know the Amazon isn't the "lungs of the world"--it takes in as much oxygen as it puts out. As deforestation continues, the resulting farms and pastures will still produce a lot of oxygen. Plus, 80% of the Amazon still remains today, with 50% of it fully protected. The alarmism doesn't match the ecological reality.
Metaculus Prediction
The Metaculus Community predicts that 13.3 million hectares of tree coverage will be lost in Brazil in the three-year period starting from 2020.
