Melting Arctic Ice May Bring Severe Winter

Well this is a kick in the ass:

Francis published a study last year in which she showed that Arctic warming might already be causing the jet stream to become more amplified in a north-south direction. In other words, the fall and winter jet stream may be getting wavier. A more topsy-turvy jet stream can yield more extreme weather events, Francis said, because weather and climate extremes are often associated with large undulations in the jet stream that can take a long time to dissipate.
“We know that certain types of extreme weather events are related to weather that takes a long time to change,” Francis said.
While there are indications that the jet stream is slowing and may be more prone to making huge dips, or “troughs,” scientists have a limited ability to pinpoint how this will play out in the coming winter season.

“The locations of those waves really depends on other factors,” Francis said, such as El Niño and a natural climate pattern known as the Arctic Oscillation. “I can only say that it’s probably going to be a very interesting winter,” she said.
Francis’ work has linked Arctic warming to the unusually cold and snowy winters of 2009-10 and 2010-11, during which the U.S. East Coast and parts of Europe were pummeled by fierce winter storms and experienced cooler-than-average conditions. The winter of 2011-12 was much milder, by comparison, but Francis said it, too, was consistent with her research. Not all meteorologists agree on the Arctic connection theory, but that may change with time.

I can just imagine more ice storms and ridiculous winds knocking out power for days or weeks.  I don't have any idea what kind of weather might result from climate change, but it seems the consensus is that it will be more extreme.
