A brief note on this: this is not yet the big "#Amazon dieback" #TippingPoint (where dieback becomes self-perpetuating across most of the rainforest) as the net CO2 emissions are still largely being driven by degradation and so can still be limited - but it's still not good. 1/7
There are several steadily worse Amazon milestones – CO2 emissions from degraded areas surpassing CO2 absorption by intact areas, intact areas becoming C sources too due to drought, & a rain-driven tipping point beyond which a wide-scale shift to savannah becomes inevitable. 2/7
