Major Earth systems likely on track to collapse. The risk is most urgent for the Atlantic current, which could tip into collapse within the next 15 years, and the Amazon rainforest, which could begin a runaway process of conversion to fire-prone grassland by the 2070s.

Giant trees of the Amazon get taller as forests fatten up on carbon dioxide
"We're not seeing signs of them dying off," one of the study's lead authors told NBC News. "They are increasing in size and number as well."

Amazon rainforest generates US $20 billion worth of rainfall each year. The study estimates that, across the tropics, each square meter of forest contributes about 240 to 300 liters of rainfall. Such estimates could support policy discussions on payments for forest protection.

The Amazon tipping point is much closer than expected due to deforestation. A new study shows that with 25% forest loss, 1.5°C of warming could trigger a shift to savannah—a catastrophe that would otherwise only occur at 4°C of warming.

Deforestation-induced drying lowers Amazon climate threshold
Nature - The Amazon forest faces a near system-wide transition of 62−77% of the area under a combination of 1.5–1.9 °C global warming and 22−28% deforestation.
