Earth may become uninhabitable in 1By due to increasing brightness of the sun. In 3-4B years it will be too hot for liquid water on the surface.

Earth is on course to become uninhabitable for human civilisation its current form within a century, with an associated mass extinction. Even if all industrial activity stopped tomorrow there's now enough CO2 in the system to guarantee a succession of uncomfortable and expensive droughts, floods, storms, and wildfires for thousands of years. If it doesn't they will become more and more extreme very quickly. If ocean acidification and warming destroy the foodchain in the seas, collapse on land will happen very quickly.

  Did you notice that you aren't wrong because you're not really saying anything at all? "in its current form" - so maybe with slightly different distribution of land use but basically fine and not necessarily as different as today is from 50 years ago? "mass extinction" already been happening for ages for many species. "uncomfortable floods/etc?" Already been happening for all of history. "very quickly" is how quicky? "more extreme" is how much more extreme?

    > so maybe with slightly different distribution of land use but basically fine and not necessarily as different as today is from 50 years ago? No, probably very much more different than that, more like rolling back on industrialisation and globalisation. Closer to 500 years than 50, without the same hope of "progress" that we had back then. > "mass extinction" already been happening for ages for many species. Yeah, we all learned about dinosaurs when we were little kids, but if humanity collapses there's no guarantee of anything similar developing after us.

      That's better putting some numbers on it. Just to be clear, are you saying climate change is expected to cause a 1500's level of industrialisation globally? I might have misread you but if that's really your claim, you should provide a source because it's an extreme claim that's wildly different to any scientific predictions I've read about. Why wouldn't there be any hope of progress? What is the force that would make this regression permanent? As I understand it, the whole problem with climate change is not the outcome of the climate but the speed of change being too high for plants and animals to adapt, either by migration or evolution.

  Indeed. Maybe once day, aliens will drop by and discover what remains of humanity. And stories will be told of how, when the time came, our species decided to bury its head in the sand and hope the problem would go away. Or maybe that we attempted to create god to come rescue us. Life imitates art. We refused to listen to the scientists.

    Why do you think aliens will drop by? If aliens were visiting every planet in the universe, don't you think we would have noticed that by now? I mean, why didn't they visit the solar system and colonize it (and everywhere else) aeons ago?

      Someone has to be the first.
      - pfdietz 2y ago
        So, your theory is aliens are abundant, but by extreme coincidence we're first?
        AlecSchueler 2y ago
        We haven't visited any other planets so we're not the first either.
