If the population goes through a Toba-esque bottleneck due to climate-change-imposed breadbasket failures and there's no free energy (oil) left to bootstrap the world back to complexity similar to today, then is that "still here"?
Does "A Canticle For Leibowitz" qualify as "still here"?
Have you considered reading the Christian eschatology Wikipedia page? It's easier to go to the source than reinventing it, you can recycle the Latin phrases too - win-win.
Arguments like these do a lot to make so many people roll their eyes at the real dangers of climate change that exist. There isn't a bit of concrete evidence nor serious predictions (not even by the IPCC) that claim climate change will be so bad in the next cnetury as to create a Toba type die-off (which by the way was, if it even affected humanity that severely since this is still heavily debated, caused by massive global cooling instead of warming). Get a grip on the real risks and work from there. Why rabidly lean towards an apocalyptic stance except out of a morbid fetishism that many humans have always had to end of the world predictions?
