The planet will be fine if you consider events like the Permian mass extinction to be "fine." If you doubt we could push things that far, see this recent MIT study: http://news.mit.edu/2019/carbon-threshold-mass-extinction-0708 http://news.mit.edu/2019/carbon-threshold-mass-extinction-07... Humans may well make it through that, but I don't think it'd be a sure thing, especially if we get secondary effects like pandemics or nuclear war.

I think some geographically isolated village may survive even a nuclear war, and as long as a village survives, humanity stands a chance. I don't rule out the possibility of us making ourselves extinct, but I think it's a low-probability outcome. Also, if only few humans remained, I'd still call it game over. WRT. the study, it's scary stuff. If that threshold truly exists, we can kiss humanity goodbye.
