Mini ice age took hold of Europe in months
4th January 2010
Around 12,800 years ago the northern hemisphere was hit by the Younger Dryas mini ice age, or “Big Freeze”. It was triggered by the slowdown of the Gulf Stream, led to the decline of the Clovis culture in North America, and lasted around 1300 years.
Hans Renssen, a climate researcher at Vrije University in Amsterdam, the Netherlands, says recent findings from Greenland ice cores indicate the Younger Dryas event may have happened in one to three years. Patterson’s results confirm this was a very sudden change, he says.
