I dunno what discussions you are referring to specifically, but the mainstream belief is that all-out nuclear war would end in nuclear winter. I have seen some posts/articles recently contesting that, which are (quietly) supported by the scientific community. we don't know for sure that nuclear winter wouldn't happen, but the foundations of the original theory have come into question under the last few decades: https://en.wikipedia.org/wiki/Nuclear_winter#Criticism_and_d...

I don't really see a meaningful distinction between "end of the human race" and merely "end of civilization as we know it", but it's interesting to learn about the current debate among experts.

That isn't an interesting debate to have or to watch.

Particularly not when as big of a chunk of our population believes the rapture is coming in their lifetimes.
