The Amazon Rainforest Tipping Point is 20-25% deforestation total.

We are at 20% deforestation now.

The forest fires stem from previous deforestation, so destruction is cumulative, exponential.

Past the tipping point the rainforest dies.

To quote the Expanse, this is the cascade, (and we are nearing the point where) this station is already dead.

That's just wrong. The fires can actually make the forest stronger next year[1]. This is part of the cycle of nature. Have you been to the Amazon? Pretty much every inch of it has burned in the past, but after a year or so, you could barely tell, as in the wet season, the plants grow a lot faster than most people who are not from the region can even imagine.

The forest does recover, unless the burnt area is cleared and planted with soy or corn of-course.
The evidence disagrees, the link I posted provides evidence that the majority of the forest fires stem from previous clearances.

While there is a natural role for fire in forests this is unsustainable and close to a tipping point of unrecoverable.
