I’m an engineer that makes those drawings and I can’t dispute this at all.

We would probably only ever get a real image like this if humanity becomes a multi-galactic race. And I agree, the odds of that are close to zero and sad.

What about tipping points? I hear about ice cover, ocean currents, and other systems where once we get past a tipping point, additional warming is self sustaining. At that point it doesn’t matter if we have our brakes on, we’ve gone over the cliff right?
