    Global warming is funny in that there is a threshold at which runaway reaction evaporates all water on the planet and changes it into inhabitable wasteland akin to other sad space rocks.

    I don’t know what are the chances for that but I feel if it is anything above 0.1% then it is too fukin big of a chance.

    I don’t want to risk that the scientists completely missed the mark in some computer simulation or missed some vital, crucial info and this is the actual scenario, those things are awfully hard to model and predict. Maybe the rate of change is so meaningful that it kicks in some bad stuff that would not happen if the rate of change was hundred thousands years. Who knows at this point. Climatologists are fumbling around in confusion

      That won’t happen, CO2 and warming has been much, MUCH higher than it is now or probably will ever be.

      What will happen is that loads of animals will die because they won’t be able to adapt quick enough. Thought that we had many extinctions now? Try a hundred times more.

      What will happen is mass crop failures due to extreme weather, and water shortages. Humans being the assholes that the are will not focus on an actual solution, they’ll just start wars over the scarce resources to make it even worse.

      Humanity actually might go extinct if we let it ge tbad enough.

      There are still many people out there claiming it’s all fake. Can we please just make them extinct?

        It begins with wiping out the brainwashed. Theoretically, this should allow democracy to correct the problems, but i suspect the owners will just stop pretending they operate within the bounds of democracy at that point and go all out authoritarian to prevent themselves from being dethroned. Then we wipe them out.

      0.1% chance would be huge. That kind of probability is an unacceptable risk even just for a personal injury, let alone the destruction of all life on earth.

        The good news is that almost all lines of evidence lead us to believe that is unlikely to be possible, even in principle, to trigger full a runaway greenhouse by addition of non-condensible greenhouse gases such as carbon dioxide to the atmosphere. However, our understanding of the dynamics, thermodynamics, radiative transfer and cloud physics of hot and steamy atmospheres is weak. We cannot therefore completely rule out the possibility that human actions might cause a transition, if not to full runaway, then at least to a much warmer climate state than the present one. High climate sensitivity might provide a warning. If we, or more likely our remote descendants, are threatened with a runaway greenhouse then geoengineering to reflect sunlight might be life’s only hope. …[2 sentences cut to meet arXiv char limit]… The runaway greenhouse also remains relevant in planetary sciences and astrobiology: as extrasolar planets smaller and nearer to their stars are detected, some will be in a runaway greenhouse state.

        We have a huge geoengineering greenhouse experiment running on earth as we speak with unclear final outcome. But at least the science of climate will become clearer during this experiment that’s for sure.

        It’s not that outlandish as one would instinctively think considering we have no idea why warming accelerated so much in the last years. It’s a good reason to act, among many others. However before that would happen obviously humanity would be long gone anyway.

        Also from interesting bits as of now theoretically our GHG ppm is the same as when there was no ice on Greenland and sea level 10 m higher. It seems we are now merely waiting for the delayed reaction because even if we would stop all emissions we would also have to remove the GHGs to avoid it.

        Another interesting thing is that scientists are intentionally underplaying some things to not appear ‚alarmist’ because it was figured out that this would have opposite and unhelpful effect to climate action. Except for James Hansen.

        In any case it’s useful to know what is the absolute worst scenario and what huge GHG numbers do to the planet(s).
