Decline of the Great Lakes Tied to Lake Ice Decline

  2. I remember walking on Lake Michigan during the winter. The ice formed by the water and wind took on fantastic shapes, it was a true wonderland. I was in school at Northwestern, in Evanston, IL at the southerly end of the lake. Thinking back on it, walking out on that ice was probably a very bad idea (though, clearly, I survived it). It's just slightly possible that my judgement was affected at that time (1972 or so) by ... external factors...

    I've swam, body surfed, sailed, flown a light airplane across, and walked on Lake Michigan. The Lake is a part of me in the way the sea is for some others. I've been in California since 1976 and I still get east and west turned around because, when you're going toward the water from Rockford, Illinois or watching the sun on the water in Evanston, you're looking east.

    I don't have much in the way of factual argumentation to make here, but this is hugely demoralizing to me.

  3. I remember the fabulous ice cliffs (high and crumpled in fantastic shapes) at sunrise on Lake Erie in 1967! No problem walking on the ice then. For some reason, "2000 light years from home" always brings back the rainbow colors to my mind. I was just a visitor.

    For the last couple of years, almost every water temperature anomaly visual has shown the Great Lakes bright red. The smaller the body of water, the quicker the consequences.

    Beautiful, if horrifying, algae bloom:

    (I think EO has lots more images for interested parties.)

    A year or so ago I followed up on some problems there and it did not look good.

  4. Ricky Rood at Wunderground has an article about the connection between the arctic oscillation (AO) and the Great Lakes, with extract here:

    These changes in the weather pattern have large consequences on the weather in the U.S. When the North Atlantic Oscillation is in its positive phase, the winters in the Mid-Atlantic and Southeastern U.S. are moist and mild. When the North Atlantic Oscillation is in the negative phase, the winter in the same regions of the U.S. are cold and snowy. Though snowy, the actual amount of water that falls from the sky is less than average.

    The discussion of the Arctic Oscillation often focuses on the winter and spring because in the U.S. the discussion of weather and climate often over emphasizes what is happening in the Interstate 95 corridor. (Isn’t it great that I-95 has its own website?). However, the Arctic Oscillation is the dominant mode of variability in the Northern Hemisphere middle latitudes, and this is true all of the year. When we say that something is the “dominant mode,” we mean that if we formally measure the variance and then try to describe the variance by recognizable patterns, then the single largest way to describe the variance is with the Arctic Oscillation.

  5. for what its worth, I-80, I-10 and I-35 all have websites form the same outfit, too...

    Thanks for the link. My education was very light on oscillations other than the El Nino. Something worth looking into.
