Boulder – Snowiest January Through September On Record

 “The first 8-1/2 months of the year have been the snowiest on record in Boulder,” says Steven Goddard website. “Almost nine feet of snow already this year.”

  1. It’s actually well known that snow levels increase as temperatures approach zero and are actually heaviest at +3C.

    It would therefore not be surprising that, with a 1C rise in temperature since 1850, that snowfall levels have also gone up.

    This is a postulate, not a claim, and it would perhaps be interesting to see if there has been an analagous temperature rise to accompany the snowfall increase.

    1. Notice how the snowfall has increased recently in the NH,

      while the temperatures have been falling in the same period,

      The Arctic icecap used to be much larger at the beginning of the XX century, when temperatures were colder.
      There were also important oscillations of snowfall during the colder period of the 1960’s and 70’s.
      Therefore the relation between temperature and snowfall is not linear.
      By simple logic, I’d say that, after a period of strong warming as happened in the last century, a colder climate would favor increased snowfall.

    2. Rhys,
      “heaviest” perhaps, yes. But snowfall measurements on the ground increase as it gets colder.
      See, heavy snowfall (around the freezing mark or slightly above) will be full of water and therefore compacts itself, making for not a lot of snow, but weight-wise heavy.
      But take the same amount of snowfall, and drop the temperature 5-10 degrees below freezing, and that snowfall becomes light and fluffy, thereby increasing the height of the snow on the ground.

  2. One thousand to fifteen hundred years ago conditions were generally wetter on parts of the Colorado Plateau than currently. However, about a thousand years ago the Anasazi natives began migrating from southern parts of the plateau east to the Rio Grande drainage. It simply became too dry for them to sustain habitations on the plateau at places like Mesa Verde and Chaco Canyon. Perhaps the 1440-year cycle is returning to wetter conditions. A simple shift in the jet stream and relocation of dominant high and low pressure patterns is all that is needed to return more moisture to areas that have generally been drier.

  3. Yes, Boulder is one of the hardest hit areas. I hate to think how they will fare if this current, seemingly endless humidity and rain in the southwestern desert, including here at the foot of the Colorado Plateau where I live, continues and turns into snow in high places like Colorado, in a month or so. Even though the storms and rain have ended here for the last few days, the humidity has been much higher 0% than our usual 5-10%.

    1. What’s interesting is that during the last major Glacial period, that part of North America (the Southwest) was wetter.

  4. There is some common sense starting in Australia, with running the article Global Warming Forecasts wrong, says U.N. report. We are actually warming at only half the rate it had claimed in 2007, the source was U.K’s Daily Mail Newspaper.
    When you are wrong and you know it, it is easier to have a polite backdown, without admitting you are wrong.
