That's a lot of ice

 


20,000 years ago the Laurentide ice sheet covered most of North America to a depth of two miles or more. Here is the southern edge as it begins its slow retreat north across Lake Michigan, with the skyline of modern Chicago to scale.

  1. Yep. And having lived within two miles of a glacier, I can categorically state that advancing glaciers are great - as long as you don’t live in their path! It’s the ultimate NIMBY situation. Receding glaciers are much easier to live with.

    1. Retreating glaciers drag a lot huge rocks and debris; they carved out the Finger Lakes in Upstate NY.

  2. Current theories:
    Homo sapiens start migrating out of Africa 44,000 years ago.
    Neanderthals diverge from Denisovans 45,000 years ago and disappear 26,000 years ago.
    Denisovans start interbreeding in Asia 12,000 years ago.
    Stone Age starts 9,000 years ago.
    Bronze Age starts ~3,300 years ago.

    Just look at all the Global Warming early man accomplished before they even had simple stone tools.

  3. Trump's fault. Change my mind...

  4. I'm longing for the good old days before global warming.

  5. That's only a 3" accumulation of ice each year for the 20,000 years before that. Which is triflingly small.

    So now we're supposed to believe dinosaur farts and a few caveman campfires warmed the earth that much and killed off the polar bears' and woolly mammoths' habitat?

    Sh'yeah.

    1. Of course you have to believe it. CNN says so.

    3. Yes, that's exactly what the Climate Change Loons would have us believe.

  6. “Every time the cataclysmic concept has come to life, the 'beast' has been stoned, burned at the stake, beaten to a pulp, and buried with a vengeance; but the corpse simply won't stay dead. Each time, it raises the lid of its coffin and says in sepulchral tones: 'You will die before I.'
    The latest of the challengers is Prof. Frank C. Hibben, who in his book, 'The Lost Americans,' said:
    'This was no ordinary extinction of a vague geological period which fizzled to an uncertain end. This death was catastrophic and all inclusive. [...] What caused the death of forty million animals. [...] The 'corpus delicti' in this mystery may be found almost anywhere. [...] Their bones lie bleaching in the sands of Florida and in the gravels of New Jersey. They weather out of the dry terraces of Texas and protrude from the sticky ooze of the tar pits off Wilshire Boulevard in Los Angeles. [...] The bodies of the victims are everywhere. [...] We find literally thousands together [...] young and old, foal with dam, calf with cow. [...] The muck pits of Alaska are filled with evidence of universal death [...] a picture of quick extinction. [...] Any argument as to the cause [...] must apply to North America, Siberia, and Europe as well.'
    '[...] Mamooth and bison were torn and twisted as though by a cosmic hand in a godly rage.'
    '[...] In many places the Alaskan muck blanket is packed with animal bones and debris in trainload lots [...] mammoth, mastodon [...] bison, horses, wolves, bears, and lions. [...] A faunal population [...] in the middle of some cataclysmic catastrophe [...] was suddenly frozen [...] in a grim charade.'
    Fantastic winds; volcanic burning; inundation and burial in muck; preservation by deep-freeze. 'Any good solution to a consuming mystery must answer all of the facts,' challenges Hibben.”

  7. The megafaunal and Clovis extinctions occurred during the Young Dryas mini ice age around 10,000 to 9.600 BC. It was likely the result of a meteor strike somewhere in central Canada.

    Gobekli Tepe is a record of this event. See, Martin Sweatman, "Prehistory Decoded," Matador, Leicestershire, UK, 2019.

    1. An area in the NE of the Bakken shield is peppered with meteorite craters.

    2. But to label that event as cause raises questions.
      It means it was of such enormity as to change global weather, and sufficient to prevent remergence of ice sheet, but not so large as to render extinct all life.

      Proffered causes of 'selective extinction' leave me wanting.

  8. If ever around Alpine Texas,go take the cruise around The Rock Pile. It's a huge pile of Huge boulders, all nicely rounded, like russet potatoes. I don't see a way for that to exist but for a glacier finally succumbing to cave man fires and dinosaur farts causing global warming.

  10. The simplest risk/reward or upside/downside analyses of "climate change" clearly show that 2 miles of ice is infinitely worse than increased tropical storm activity and sea level rises over 300 years requiring that cities be moved a few feet with the upside of millions of square miles of additional arable land in Canada and Russia.

    There is no upside at all to cooling, none, de nada, nichts, nothing, it's all bad.

    1. Good luck planting crops when the nearest dirt is under 2 miles of ice.

  11. For years as the global warming crown screamed I said often ICE ages come and ice ages go, the next one is when not if. The planet doesn't have a thermostat you can set.

  12. Aaand that is exactly what they want for you and me. A thermostat YOU can't set.

  14. The position of the Earth's poles haven't remained stationary. You heard it from me first.

  15. If you are going to post statements about glaciers, don't be so incredibly inaccurate. Show a detailed map. Time waster, you are living up to your name. Waster.
