    Thwaites Glacier has developed multiple massive cracks in the last week, and huge parts of it seem to be breaking off.

    We are talking approximately 2,000 km², about half the size of Rhode Island.

    That amount of ice, which will melt after it breaks off, would be roughly 0.67cm of global sea level rise on its own.

    The Thwaites Glacier is also known as the Doomsday Glacier, because once it starts to go, it will not stop… and it is now collapsing far faster than previous consensus estimates.

        Thats wildly optimistic.

        By the time the damage piles up, there will not be enough sociopolitical cohesion or spare resources to invest in meaningful mitigation.

        We are in a global civilizational death spiral, a mutually reinforcing polycrisis, a complex systems collapse.

        Some places and countries will fare relatively better than others, but they’re all looking at massive declines in absolute terms.

        I’d say we’d be lucky to hit 2100 with a total world human population above 3 billion.

        Here’s the most recent calibration of the World 3 model, from ‘The Limits to Growth’ in the 1960s:

    Meanwhile, in Florida, we just blew past our snow record of 3", set in 1895, to 7.5". You have to wonder just how much hot air slammed into the polar vortex, and how hard, to send that all the down here.
