There's no way climate change can wipe out the entirety of humanity and make the earth uninhabitable, especially in the next 15 years. Are greenhouse gases supposed to turn Earth into Venus in 15 years? That's the only way I see that it can truly become "uninhabitable", and I don't see how that can happen.
Even then, a small percentage can always survive in closed-loop habitats shielded from the outside world, ala Biosphere 2.0.

- pmiller2 7y agoMaybe not in 15 years, but climate change can cause enough of the earth to become uninhabitable that civilization crumbles. Wiping out 95% of humanity would almost certainly be enough to cause the downfall of modern society. Your Biosphere future is a highly optimistic one, IMO.
- NeedMoreTea 7y agoThe nearest humanity has got to a closed-loop habitat, that works on an ongoing basis, were the Soviets in the seventies during their lunar programme. We are far away from one that's viable. It can be the new fusion: "ready in twenty years"... indefinitely.
