What's Causing This Extreme Winter Weather?

A new study suggests that rapid increases in temperature in the Arctic are causing the jet stream to change.

As much of the U.S. has endured a seemingly endless string of nasty winter storms, some scientists are suggesting that an altered jet stream pattern might be to blame.

Is this unusual or just a bad winter? One study suggests that climate change has altered the jet stream creating a situation where weather patterns are stagnating over the U.S. 
The study, according to Time, shows that the jet stream over Northern Europe and North America has shifted . The study found that as temperatures continue to rapidly rise in the arctic, the temperature difference between the Arctic and middle latitudes is diminishing – slowing the jet stream.

The BBC reported that as the jet stream slows, it has begun taking a longer, more meandering path. Consequently, weather patterns tend to become "stuck over areas" and cold weather is driven further south while warm weather is driven further north.

However, other scientists have disputed the notion that climate change is to blame for shifting the jet stream.

The Daily Mail quoted climate professor Mat Collins as saying "There is no evidence that global warming can cause the jet stream to get stuck in the way it has this winter. If this is due to climate change, it is outside our knowledge."

How long? Until the cows come home, when the chicken comes home to roost. Until perches grow on mango trees in February.... Until the sees run dry, and the hills turn to dust....until the stars go out....And if their is a life after this....until forever there....Or, until I get tired and bored here, which could be anytime now.

This world without end.... I think refers to the end of Earth, and it's the next world without end

Update: Large Democrat donor threatens to withhold $100million from the Democrat campaign funds if they don't get serious about global climate change. Result: Dems pull an all nighter to discuss global climate change. Hmmm. What is the one thing politicians want most? More power. How do they get more power? More government. How do they get more government? Creating a threat and needing to create another govt entity, raise taxes to pay for it.

Chris, here is the story: ( http://www.latimes.com/nation/politics/politicsnow/la-pn-senate-climate-change-20140310,0,5951075.story#axzz2vcRe5t6p ) The glacier in the poster has been retreating since the mid 1700's. Underneath, the land is exposing what was a forest during the medieval warm period, until the little ice age. Coming out of the little ice age as we have been brings it back to what it was before. But these people cherry-pick locations and time periods to suit the propaganda. ALWAYS, I STATE THE SAME....IF IT WAS TRUE, THEY WOULDN'T HAVE TO LIE. ( http://notalotofpeopleknowthat.wordpress.com/2013/08/26/retreating-alaskan-glacier-reveals-remains-of-medieval-forest/ ) ( http://www.wunderground.com/news/melting-glacier-exposes-frozen-forest-20130924 ) WIKIPEDIA IS INTERESTING. They describe the retreat because of coming out of the little ice age. They don't realize the description of the slowing of retreat and times of more retreat coincide with the sun cycles, and global tenmps of the 60 year cycle.

Now that we have google earth, one can look at the larger picture of the muir glacier, and actually see the expansion of ice from 1994. GLOBAL WARMING: If it were true, they wouldn't have to lie. Disclaimer: Although the glacier topic is something I don't know much about, Its probably more than these senators.
