Rainforest Roulette: What Happens When the Amazon Goes Dry? Scientists Have Answers

Biomass Collapse: The experimental area lost approximately 40% of its vegetation biomass, with large trees dying off first. This shifted the rainforest from a carbon sink to a carbon emitter before stabilizing.
No Savanna Transition: Contrary to earlier predictions, the drought-stressed forest did not transform into a savanna, retaining its structural integrity despite significant biomass loss.
Human Impact: NASA studies cited in the research highlight that human activities, including deforestation and greenhouse gas emissions, have intensified atmospheric dryness, exacerbating drought conditions.

A 24-year drought simulation in the Amazon rainforest has uncovered critical insights into how the ecosystem responds to prolonged dryness. Conducted by Brazilian and British scientists in the Caxiuana National Forest, the Esecaflor project diverted 50% of rainfall from a one-hectare plot using t...
