Scientists Marvel At 'Increasingly Non-Natural' Arctic Warmth (msn.com) 481

mmell writes: Recognizing that this is a dreadfully old story (at least by Slashdot standards), current developments make this once more a current story. Scientists studying the Arctic environment are used to seeing broad variations in average temperature readings, but recent results have been so far beyond the normal range that they are only able to conclude that they are being caused by human activity. The temperature data (which includes a great many days with readings above 0C) is bolstered by measurements showing that the Arctic ice shelf is both thinner and less extensive than has ever been previously recorded. I wonder if the Arctic ice cap will reform in the winter, or if it's possible that its absence will cause irreversible changes to the Earth's ocean currents (and by extension, Earth's climate)? "[A]fter studying the Arctic and its climate for three and a half decades, I have concluded that what has happened over the last year goes beyond even the extreme," wrote Mark Serreze, director of the National Snow and Ice Data Center in Boulder, Colorado, in an essay for Earth magazine. According to The Washington Post, the scientists' simulations predict some places in the high Arctic will rise over 50 degrees above normal. One chart, embedded in the report and shared by several meteorologists online, shows a "jaw-dropping and emblematic display of the intensity and duration of the Arctic warmth. It illustrates the difference from normal in the number of 'freezing degree days,' a measure of the accumulated cold since September."

      I feel reminded of the Dead Parrot sketch by Monty Python

      cue a flooded street, two men standing in front of a wall of sandbags that tries its best to keep the flood out

      A: Hello? I'd like to register a complaint. About the climate change.
      B: Oh yes, yes, the climate change, the biggest science hoax of the century, yes, what about it?
      A: What about it? It's coming right up to my front door here!
      B: Oh no, no, that's just ... rain.
      A: Look, matey, I know a flood if I see one, and that's a flood, no rain.
      B: No, no, that's rain. We get that a lot lately. Wonderful weather, ain't it? Relaxing and soothing the pitter-patter of drops...
      A: Pitter-patter? No pitter-patter enters into it, it's a flood!
      B: Oh, that water you mean? Yes, that's coming down the hill. Happens sometimes.
      A: Down the hill? The hills are dry as bones since the glaciers went away, but there's no beach anymore. Actually THIS IS the beach!
      B: It's not (take a pump and pumps some of the water back out behind the sand bags) See? It's reciding!
      A: You pumped it out.
      B: That was you moving the water.
      A: I never did such a thing!
      B: (pulls a sand bag out of the wall, an arm thick stream of water starts to flood the area). See? It's flooded!
      A: You made it!
      B: I what?
      A: You made the water appear. You're trying to trick me into believing you.

      and so on.

      Claiming that humans will go extinct just hands the denialists a convenient straw man to attack. Scientists aren't predicting anything that humans can't adapt to. But they are predicting changes that spell the end of things that many are emotionally attached to, like species endangered by changing habitats, or ways of life which are no longer possible in certain places (e.g. drought-driven failure of family farms in certain locations).

      Another way of looking at climate change is purely as an economic tradeo

  • There is a reason I chose to live at elevation in the colder north of England.

    At 50 degrees (Fahrenheit right?!) I should be living in a tropical environment very soon. If sea level rises significantly land value will rise as well.

    This simulation model really does sound fantastic...but for full disclosure, was my estate agent involved in the creation of this model?

    I mean, not that it does not sound awesome but isnt a computer simulation a thing in which scientists make educated guesses as to parameter

      You know what happens in a tropical environment? Tropical storms. You know what tropical storms plus sea level rise equals? You're fucked. HTH, HAND!

        Sea level rise has been estimated to be on average between +2.6 millimetres (0.10 in) and 2.9 millimetres (0.11 in) per year ± 0.4 millimetres (0.016 in) since 1993 Sea level rise [wikipedia.org]

        One tenth of an inch a year, I'm just not feeling your sense of urgency here; especially since

        new analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001. That net gain slowed to 82 billion tons of ice per year between 2003 and 2008. NASA Study: Mass Gains of [nasa.gov]

          Yeah, let's wait until it's urgent, and then find out we're too late to change anything.

      Says who? Another likely outcome is that ocean circulation patterns will change and we'll lose the North Atlatic drift. The northernmost point of England is comfortably above Goose Bay in Canada, just across the Atlantic. You might like to look at pictures of the area in Winter, in order to see what a not entirely unlikely outcome for England is.

      You have a cute idea that raising sea levels will just mean property values of higher land goes up.

      That is not what will happen. History shows us that people dispossessed of land (by, say, flooding) don't just roll over and disappear. They don't turn up on your street, decide it's too pricey and meekly head off somewhere else where they won't be a bother.

      They are refugees. They need somewhere to live. If they can't buy property, they will squat. They will set up a tent in your front garden, and to

    It's been hot this summer, really hot so naturally, I'm catching some waves.

    The water is cold, icy cold and I'm only half joking when I say, 'now we know where the icebergs are melting to'. I know it's subjective, I posted this in previous years, however I have decades of experience in the ocean and I remember by month just how cold the water should feel for that time of year. My mental map of the way the ocean should feel is changing enough to notice.

    I can sustain a 2+ hour body surf if I have time. I

  • It's still a friggin' simulation. Occam's Razor says it's a bug in your code.

    • It's still a friggin' simulation. Occam's Razor says it's a bug in your code.

      Occam's Razor says the simplest answer tends to be correct, when your trying to model systems with multiple nonlinear dependant varibles; the simplest answer is any output is chaotic crap, no matter how good your code is.

        OK, tell you what, I'll model a chaotic simulation and you bet against me being right.

        The weather is chaotic and so unpredictable.

        Bet you $1000 that it doesn't snow on August 1 in London.

  • ... specially those scientist living there warming the place, if they moved out it would obviously cool down again.

    Once the humans are gone.

  • Whatever happened to "unnatural" or simply "abnormal"? Why do people keep insisting on using "non" as a prefix?

    I love how Slashdot champions every feat of engineering and scientific discovery, until it relates to climate.

    The cognitive dissonance is deafening.
