An Extremely Cold 2012-13 Winter Doesn’t Disprove Climate Change – May Confirm It. Record Arctic Ice Melt.

Extent of record Arctic ice melt in summer 2012.The Huffington Post posted an article, “Arctic Ice Melt Could Mean More Extreme Winters For U.S. And Europe,” forecasting extreme changes in 2012-13 winter weather patterns caused by the record Arctic ice melt. Scientists Jennifer Francis [Rutgers] and Stephen Vavrus [Wisconsin-Madison] published their study in March 2012 and in it, predicted that due to Arctic amplification, extreme weather events [cold spells, droughts, flooding] would not only occur but will be more persistent in northern latitudes. The 2012 record Arctic melt is changing the shape and direction of the jet stream and will lead to prolonged weather events. Check out the article for more information.

Personally, it gets a little tiring listening to both sides of the climate change issue point to the weather at that moment, and location, as a sign of change or no change. We’ll see if the predictions made in the Francis/Vavrus study play out during the course of the 2012-13 winter. Unfortunately, they nailed it this summer. [Huffington Post]
