Amazon rainforest could reach ‘tipping point’ by 2050, scientists warn

We need to respond now,' says author of study that says crucial forest has already passed safe boundary and needs restoration

Up to half of the Amazon rainforest could hit a tipping point by 2050 as a result of water stress, land clearance and climate disruption, a study has shown.

The paper, which is the most comprehensive to date in its analysis of the compounding impacts of local human activity and the global climate crisis, warned that the forest had already passed a safe boundary and urged remedial action to restore degraded areas and improve the resilience of the ecosystem.
