Amazon rainforest at risk of reaching tipping point by 2050

A study warns that up to 50% of the Amazon rainforest could reach a tipping point by 2050 due to water stress, land clearance, and climate disruption. The forest has already passed a safe boundary, with 15% cleared and 17% degraded. By 2050, 10-47% of the forest could face compounding disturbances. To prevent collapse, deforestation should be limited to 10% and global heating to 1.5C above pre-industrial levels. The Amazon's importance and complexity are not fully understood.
