Summary: TEHRAN (FNA)- For more than 30 years, climate scientists have debated whether flood waters from melting of the enormous Laurentide Ice Sheet, which ushered in the last major cold episode on Earth about 12,900 years ago, flowed northwest into the Arctic first, or east via the Gulf of St.Lawrence, to weaken ocean thermohaline circulation and have a frigid effect on global climate.
It did not appear south of the area covered by the Laurentide Ice Sheet (which reached its most recent and maximum extent about 18,000 years ago) until 10,000 to 12,000 years ago, when it is found in southern Alberta, southern Saskatchewan, and the bordering US states.
