In the exact same way major sudden changes in the climate have lead to the extinction of the majority of plants an animals over this planets history. We are not special.

We are special in many ways, we have technology, we are everywhere, and we can think and plan (although considering global warming that is debatable). Global warming would have to create dramatic conditions everywhere on the planet, not leaving any small pocket of survivability to make humans extinct.
Possible? Theoretically yes, but pretty unlikely. But obviously extreme global warming would be a catastrophe even if some of humanity survive.
Technology depends on a lot of people cooperating around the globe. Disrupt a few critical chains (power generation, fertilizers, computers), add a bit of good old war and you'll soon be in the era before Haber process and a lot of people die. And then the remaining people will have trouble keeping that level of technology with how sudden the change would be.
Well yes that's what I said, it could destroy civilisations and their technology. It seems much harder to kill every isolated tribe in the whole world, and every survivors of the destroyed civilisations.
There's little evidence that humans are able or willing to cooperate at this scale. See: the past century of climate change.
Runaway greenhouse effects on other planets have resulted in surface temps of 400C+
Yes, but Venus has 93 times the atmospheric pressure of Earth, and it's overwhelmingly CO2.
Earth isn't likely to get a true runaway like that until the sun gets another billion or so years on the clock, and when it does it will be water vapour as the oceans are promoted to atmosphere.
What we're doing to ourselves is still bad, of course, but it's nowhere near that bad.
Is there a possible scenario for that on earth, that results in every place on earth having a temperature non survivable by humans?

We have a massive survival range and we're on every continent. That kind of sudden climate change is not nearly enough to wipe us out. Some other climate scenarios might. Nuclear war definitely could.
The thing that would end our species due to nuclear war is the exact same thing that would end us from climate change - a collapse of the modern systems of society that we depend on for survival. A nuclear exchange won't set every human on fire, but it's the collapse of food production, healthcare, logistics chains, security, and eventual disease that follows. And because of the size of our population and how depended the majority of us are on these systems, it would likely happen extremely quickly before plateauing out to very small, scattered population groups that would struggle in a hostile environment.
Outside of extreme feedback loop scenarios, there is no way for climate change to disrupt food anywhere near the level of nuclear winter, and there would be no mass destruction of supply chains either.

So you agree they would survive
