    Last year, the National Science Foundation and Britain’s Natural Environment Research Council launched a joint programme called the International Thwaites Glacier Collaboration to study the unstable glacier and its role in sea levels.

    The Thwaites Glacier, about the size of Florida, holds enough ice to raise ocean levels another 60 centimetres if it completely melts.

    It also backstops other glaciers capable to raising sea levels another 2.4m.

      1. 2.2.1

        Hey e hoa, check out RedLogix’s comment and link at 10 on today’ s Open Mike if you haven’t already. Wonderful.

        When does the MM home school restart, or has it already started?

    4. 2.4

      SPC (2) … Many thanks for posting.

      One massive glacier breaking down, such as that the size of Thwaites, has the potential to alter the geographics of the planet, considering the amount of water that could be released. Extremely scary stuff. Indeed enough so to force us to sit up and take notice. Not something to be ignored at all.

      Let’s see how the climate change deniers manage to explain this one away!

      1. 3.1.1

        “As with the northern hemisphere and the Arctic, there is also a southern hemisphere polar vortex. This polar vortex also extends through the stratosphere and into the mesosphere. In contrast to the northern vortex, the southern vortex is stronger, larger, and longer-lasting. In addition, temperatures are colder and ozone levels are lower than their northern counterpart.”

        1. 3.1.1.1

          Which, if my reading is correct, is good for us – the wall between us and the super-cold winter air is stronger, for longer.

          The role of mountain rangers and land/sea interaction was interesting.

          1. 3.1.1.1.1

            think it may pay to reread….only saving grace for southern hemisphere is the comparative lack of inhabited land mass at similar latitudes

            1. 3.1.1.1.1.1

              But the supercold snap in North America is because their vortex broke down and released the supercool air, no?

              It’s not my field or anything, so that wasn’t a rhetorical “no?”

              1. 3.1.1.1.1.1.1

                “Of special interest is the southern hemisphere vortex in 2002. That year had the first major warming observed in the southern hemisphere stratosphere. It was a wave-2 warming and the vortex split into two parts.”

                less volatile, but not immune….and with warmer water/air temps, altered air/water currents and reduced antarctic ice?

                1. 3.1.1.1.1.1.1.1

                  No, not immune.

                  But still stronger, for longer.

                  Anyhoo, it was an interesting read, and the role of mountain ranges was intriguing. Still working through the idea that the Andes have less of an effect because they’re narrow on a longitude basis.

                  1. 3.1.1.1.1.1.1.1.1

                    we had a ssw event although smaller in november

                    http://ds.data.jma.go.jp/gmd/tcc/tcc/products/clisys/STRAT/gif/pole30_sh.gif

                    enough for a polar breakout,regime change in the southern annular mode.

                    and fast moving polar fronts onto eastern South island and subsequent wet events.

                    The NH ssw event

        2. 3.1.1.2

          Physics for dummies;

          (So simple even a President could understand it).

          You leave the fridge door open – Near the fridge the temperature will drop. – Inside the fridge the temperature will go up.- But overall, on average, the whole kitchen will be warmer.

          Swap, ‘fridge door’ for Polar Vortex.

          Swap, ‘Near the fridge’ for North America.

          Swap, ‘Inside the fridge’ for the Arctic

          And swap the kitchen for the whole world.

    2. 3.2

      Yes that’s Chicago. We lived there for a couple of years in the nineties (our apartment building was right by the pier sticking out into the lake in the middle of the picture). Winters were always fierce but we never saw the lake frozen quite as much as this.

      Cool city Chicago as cities go.

      2. 3.2.2

        The steam rising off the open water in the upper left is pretty cool. The air has to be seriously cold for water as cold as Lake Michigan to be steaming. A good illustration of where “lake effect” snow comes from.

    3. 3.3

      Yep a slightly more benign version of the Day after Tomorrow movie. But the warning is still loud and clear. I hope our leaders hear it.

          1. 3.3.2.1.1

            It’s kind of a habit of mine. If I see something that gets attention because it’s swung out of normal one way, I get curious about what and where might there be a balancing swing the other way.

            That was a pretty big article already without delving into sea temps. Add those and it’d blow way out.

            1. 3.3.2.1.1.1

              not a criticism, more thinking out loud….if the scientists who study this for a living havnt a definitive cause yet its more reason to adopt precautionary principle.

    1. 5.1

      Hey, don’t apologise, that’s a big article that I mostly just linked to for the temp map in it. If there’s other details worth checking out more carefully, cheers for highlighting it. Besides, it’s someone else’s work, I got zero proprietorship over it.
