The homo genus has survived huge variations over the last 200k years. The likely global warming scenarios are very bad but extinction would need a major screwup with AI and/or genetic engineering. Evolutionary processes will prevent total extinction, even if "the next generation is raised" one way, new trends will emerge. A population of few thousand is enough for humanity to come back. Even if population dropped 50% every 30 years, it's still 500 years to get down that low. And we haven't even started trending downward yet.
