It's not that nothing is knowable, it's that predicting the future is hard and easy to get wrong, particularly with something as complex as civilization, since humans adapt and civilization changes. The same applies to the biosphere as well. Saying for example that polar bears will go extinct or coral will all die off is ignoring the possibility that some bears and coral will adapt to the warmer world. We can't be sure about such predictions. We need to see how life and civilization responds.
- AstralStorm 7y agoUsually the life responds by getting extinct, as seen in so many species lately. What makes you think humans are special? Do you expect speciation for a change that will take less than 100 years? Technological evolution on an unprecedented scale? Because this is what it is going to take. Not even going underground en masse will work and that is essentially the most extreme social change I can see. (Even more extreme than space travel, cars, internet.)

Do you have a count of how many have gone extinct in the past decade? > What makes you think humans are special? Our brains. And yes, technology and science. Humans are extremely adaptable. Our ancestors survived an ice age with stone aged tech and spread around the world to live in all sorts of environments. > Not even going underground en masse will work LOL, what? Who is saying that the Earth will become so hot that we won't be able to survive on the surface? You think 3-4°C is going to have that effect?
