I think differences between scientists on feedbacks & irreversible/runaway climate scenarios is one of the trickiest areas.

Are feedbacks factored into the IPCC models adequately?

Would 2.5°C likely trigger 3°C and so on, or is there 0 evidence for this? Tricky, tricky, tricky.

Also, how much warming is locked in and why?

Would 3°C cause total collapse or is it 4°C for end of civilisation?

It seems obvious that the more warming there is the more dangerous the world becomes politically, though not everyone agrees on that either. 'Thriving' at 2.5°C?!?

I was mulling over this from @MichaelEMann.👇

I think (or, I think I think) that it must be accepted as unknown territory despite all the scientific understanding, and that therefore 'risk' becomes the key word.

But the uncertainty & debate is unsettling.

Thoughts @JKSteinberger @DavidLWindt @fragmansixty9?
