Oh we will, I have no doubts about that. If we are still here in any significant numbers 100 years from now it will be a miracle. Religious zealotry towards prophets and/or profits means climate change gets ignored.

You think climate change will wipe out a majority of people, and within only 100 years?

If so, you're ignoring science just as much as the religious zealots.

Global warming can't do it directly, but the resulting instability -- mass migration, famine, political and religious zealotry -- could certainly increase the odds of nuclear conflict. I doubt that a majority, i.e. 3.5+ billion, will die, but it won't be pretty.

I think most climate scientists will tell you they just don't know what will happen that far out.

Political zealotry is just as dangerous, if not more so. A singularity or nuclear war is more of an existential threat than any religious ideology could ever be.

Well, if _you_ indeed have any nukes or involvement with those humans referenced in this story (as implied in your comment) and even if not, then this song might give you a smile.. and some pause before listening to someone who would feel no remorse for making Life extinct: [Randy Newman - Political Science ("Let's Drop the Big One")](https://www.youtube.com/watch?v=PGO42gvCSPI)
