Amazon rainforest 'close to irreversible tipping point'

Forecast suggests rainforest could stop producing enough rain to sustain itself by 2021

Soaring deforestation coupled with the destructive policies of Brazil's far-right president, Jair Bolsonaro, could push the Amazon rainforest dangerously to an irreversible "tipping point" within two years, a prominent economist has said.

After this point the rainforest would stop producing enough rain to sustain itself and start slowly degrading into a drier savannah, releasing billions of tonnes of carbon into the atmosphere, which would exacerbate global heating and disrupt weather across South America.
