As deforestation and climate change threaten to transform the Amazon, there is growing concern that the ecosystem may be reaching an irreversible tipping point, beyond which self-reinforcing feedback loops would lock the system in a degraded state and lead to the Amazon flipping from a carbon sink to a carbon emitter.



Summary

The Amazon rainforest faces an imminent crisis due to deforestation and climate change. Scientists fear the ecosystem is nearing a critical tipping point. Beyond this threshold, self-reinforcing negative feedback loops would accelerate degradation. This means the rainforest could irreversibly transform into a savanna-like state, losing its biodiversity and essential functions. Critically, the Amazon, currently a carbon sink, could flip and begin releasing more carbon dioxide than it absorbs, exacerbating global warming. This transition would have catastrophic consequences for the regional and global climate.
