SUDDEN FREEZING NORTHERN HEMISPHERE 12,800 YRS.AGO

Posted on November 16, 2009 by Jeffrey Newman

Scientists have found definitive evidence that the northern hemisphere of the earth was put into a speedy deep freeze 12,800 years ago, over a period of just months, resulting from a sudden slowdown of the gulf stream. This allowed ice to spread hundreds of miles southward from the arctic. Previous research suggested that the change took over ten years. William Patterson, Geological Sciences Professor of The University of Saskatchewan in Saskatoon Canada, who conducted the extensive study said that the findings suggest that the earth’s ckimate is unstable and can flip from warm to cold rapidly with the right trigger. Some scientists have suggested that if the Greenland ice cap melts, a similarly dramatic effect may occur by disrupting the ocean currents.
