Researchers are concerned about a huge chunk of ice larger than Mexico failing to refreeze as temperatures drop in Antarctica.

      Yeah, that wording is clunky. I guess, according to the article, the ice is known to melt and return in a cyclical pattern every year. This year almost a million square miles of ice did not form as expected.

        The whole article is a bit clunky to read.

        “The word ‘unprecedented’ gets thrown around a lot…” Are you trying to reach a minimum word count?

      Right now, it’s winter in the southern hemisphere. Sea ice should be expanding around Antarctica, but it’s doing so much less than previous years. It’s so bad there’s a chance there won’t be any sea ice by the time it’s mid summer there, in December/January/February. If that happens, there’s nothing to stop the land glaciers from slipping into the sea and significantly raising sea levels worldwide. Could be like 10 feet of sea level rise depending on what happens. (Thwaites Glacier has been named in many articles as especially precarious and able to contribute 10 feet on its own.)

        I share your concern over the risks posed by the loss of sea ice. However, per the Thwaites Glacier Collaboration, even if the entire glacier were to collapse it would amount to around a 65cm rise of sea level, and the majority of that would come in the 22nd and 23rd century.

          Ok, cool. idk. Was just referencing stuff like this, from Wired: “If it totally melts, the Thwaites Glacier, aka the Doomsday Glacier, could add 10 feet to sea levels. Sea ice protects Thwaites and other glaciers because it acts like a buffer, absorbing the energy of winds and waves that would otherwise erode them.”

    This is the best summary I could come up with:


    Researchers are increasingly concerned about a huge chunk of ice — larger in area than Mexico — failing to refreeze as seasonal temperatures drop in Antarctica.

    “Unprecedented is a word that gets bandied around a lot, but it doesn’t really get to just how shocking this is,” Hobbs, a sea ice scientist at the University of Tasmania, told The Guardian.

    “There’s a sense that something weird is going on,” Walt Meier, a senior scientist at the National Snow and Ice Data Center at the University of Colorado, told The Guardian.

    We’ve seen strong declines in the amount of Antarctica’s sea ice since 2016, with experts still debating how much human activity is contributing to the trend.

    Concrete evidence is proving hard to come by, due to the complexity of the continent and its surrounding ocean’s dynamics.

    “The Antarctic system has always been highly variable,” Ted Scambos, a glaciologist at the University of Colorado Boulder, told CNN.

    There’s supposed to be quite a few things down in that ice. Some encased. Some not so much. Some natural. Some not so much.

    if ice fails to re-freeze, it’s not really ice anymore, is it?

    was this generated by AI or something? such a shit article

        The discovery channel was showing ice shelves sloughing off into the ocean in 2011. They made it sound like it’d all melt soon.

              And from images of ice cascading into the sea, you genuinely drew the conclusion that Antarctica would be completely ice-free in less than 12 years?

              So, nobody actually told you that, you just decided it was true after seeing video of ice falling into the sea. But that decision was firm enough in your mind to cause you to believe that, since there is still some ice in 2023, the doom-sayers of the Discovery channel were wrong and we had nothing to worry about?

              Fascinating. I wish I had the ability to make those kinds of amazing leaps of reasoning on subjects I know absolutely nothing about and then believe them hard enough to post snarky shit in public.
