Not to diminish the threat, but I think the impact of climate change on human civilization is often overrated. Countries most affected will include India, Bangladesh, Indonesia... none of them in the modern global powers. What I expect 50-100 years from now is: In most affected countries, mass precarity, mass migrations, hardening of borders, end of the relative post-WW2 world peace. In Europe/USA, flooded areas will be evacuated/relocated. Living conditions will worsen as a result of the end of globalization. In Russia/Greenland/Canada, warming temperatures will create more temperate areas. This will create new economic hubs, and the economic growth paradigm will prevail. Business will continue, and conditions will worsen for another 100 years. After that, a sizeable portion of Earth will be unfit for humans, and human population will have decreased a great deal. But no end of the human race visible for now.
