    Melting tundra releases methane, accelerating the increase in temperature. Rising temperature reduces polar ice, making oceans absorb more heat, accelerating heating. Climate pattern changes cause more frequent and larger wildfires, accelerating heating.

    There are probably processes that work to reduce heating as it increases that I’m not aware of, but there are a lot of positive feedback processes which is concerning.

    I believe the IPCC 1.5C was criticized because it included effects of a carbon sequestering process that hasn’t been invented yet. That’s pretty optimistic.

      Nuclear war, for one. In a more naturalistic vein, asteroid strike or massive volcanic eruptions. People worried about climate change just refuse to look on the bright side.

      Which is why I support the idea of setting up bases on the Moon and/or Mars.

      Everything is accelerating, and nobody gives a fuck to do anything before it’s too late. I hate the argument that NASA doesn’t push its budget to prevent CC or even Space X. Because stopping CC is a global effort on a colossal scale. It’s not going to work until it’s too late. Might as well get off this rock.

      Edit: Very fucking optimistic of you all

        Ignore them. They’re so hopelessly black-pilled, they’re not likely to support any significant course of action.

        We’re gonna have to kickstart human expansion into space to not only save ourselves from climate collapse but also what’s left of the biosphere. You’re not wrong at all.

        If we can’t make Earth livable we certainly can’t make the Moon or Mars livable. At best it will be a handful of people living miserably for a short time. “Get off this rock” just isn’t a realistic option, and we don’t have the time to make it so.

        The Earth would be more habitable than the Moon and Mars even in worse than worse case scenario climate change conditions. The atmosphere will still protect us from cosmic radiation, and we won’t need pressurized suits and habitats. A lot of people will suffer and die, but humanity will not go extinct because of climate change, our society will though.

        If you think leaving earth is going to solve our problems then I have a huge fucking bridge to sell you.
