You're reading too much into what I said. I didn't mean to imply that global warming will end the world with certainty and definitely not that the planet will blow up. I simply meant that the probability of the world (in the sense of the human civilization in its current form; definitely not the planet itself) ending from global warming is greater than it ending from god-like AGI.
I don't consider this a controversial statement. From my own reading of the relevant studies, I think there is definitely a non-negligible probability that runaway effects may make Earth very harsh or even completely unsuitable for human life, eventually. Are you saying the current studies outrule this scenario entirely or with near certainty?
