Brutal Winter Caused By Changing Jet Stream, Scientists Say Warming Arctic Temperatures Are To Blame

Winter storms, especially in North America and Europe, seem nearly endless these days. After one marches through and dumps its freight, another is just a few paces behind. What's worse, the bitter winter weather we're experiencing could be the start of a long-term trend. A recent study of global weather patterns is helping scientists understand how a changing North Atlantic jet stream could mean that colder, longer winters are here to stay.
