Not by Fire but by Ice


Discover What Killed the Dinosaurs . . . and Why it Could Soon Kill Us


Ice age engulfed Europe in a matter of months

11 Nov 09 - About 12,800 years ago the northern hemisphere descended into a period of glaciation known as the Younger Dryas, which lasted around 1,300 years. The Younger Dryas - named after an alpine/tundra wildflower - marked the extinction of the mammoth, the mastodon, and many other ice-age animals, and marked the disappearance of the Clovis culture in North America.

William Patterson of the University of Saskatchewan and his colleagues studied a mud core of Younger Dryas age taken from an ancient lake in Ireland. Using a scalpel, they sliced  layers from the core measuring 0.5 to 1 millimeter thick (the thickness of 10 to 25 hairs). Each layer represented up to three months of time.

The researchers determined that temperatures plummeted within a matter of months, or a year at most. "It would be like taking Ireland today and moving it up to Svalbard" in the Arctic, says Patterson.

          As you know if you’ve read either Not by Fire but by Ice or Magnetic
          Reversals and Evolutionary Leaps, I think it is no coincidence that the
          Gothenburg magnetic excursion coincided with the beginning of the
          Younger Dryas.

          You’ll also remember reading that all ice ages during the last 250,000
          years – ALL of them - began in less than 20 years, sometimes in less
          than three years.

          This new discovery ups the ante.
