Linking weird weather to rapid warming of the Arctic

Professor Jennifer Francis recently presented evidence showing that the loss of Arctic summer sea ice and the rapid warming of the Far North are altering the jet stream over North America, Europe, and Russia and these profound shifts increase the likelihood of more extreme weather.  The so-called jet stream has increasingly taken a longer, meandering path, which has resulted in weather remaining the same for more prolonged periods.
