Chicago (AFP) - A warmer Arctic could permanently affect the pattern of the high-altitude polar jet stream, resulting in longer and colder winters over North America and northern Europe, US scientists say.
The jet stream, a ribbon of high altitude, high-speed wind in northern latitudes that blows from west to east, is formed when the cold Arctic air clashes with warmer air from further south.
The greater the difference in temperature, the faster the jet stream moves.
According to Jennifer Francis, a climate expert at Rutgers University, the Arctic air has warmed in recent years as a result of melting polar ice caps, meaning there is now less of a difference in temperatures when it hits air from lower latitudes.
"The jet stream is a very fast moving river of air over our head," she said Saturday at a meeting of the American Association for the Advancement of Science.
"But over the past two decades the jet stream has weakened. This is something we can measure," she said.
As a result, instead of circling the earth in the far north, the jet stream has begun to meander, like a river heading off course.

Well, no use defending the indefensible. Those numbers don’t even come close to substantiating my point. I concede to your superior knowledge, and thank you for uplifting my understanding towards your level.
The primary cause is the Rockies. The rising air causes a mean ridge over the Rockies and a mean trough in the jet over central north america. That varies due to weather but is there on average.
I believe that these researchers should have to spend a month at the respective poles during their winter months before being allowed to pass their, ‘knowledge’, on to the rest of us.
What it boils down to is that they are no better than the snake oil salesmen of the past and should be treated accordingly
Do these "scientists" do double shifts as part time New York bridge salesmen ?
RE: “You know, Earth is mostly a molten planet, with a very, very thin crust upon which we float. How come no one ever discusses the heat radiation from within?”
Although the interior of the Earth is incredibly hot, very little of that heat makes it to the surface.
Most of that energy is consumed by “continental drift,” in other words, the motion of the tectonic plates under the great land masses at Earth’s surface.
The sun radiates about 350 watts per square meter onto the surface of the Earth.
Energy that travels from the Earth’s core to the Earth’s surface is actually less than 1 watt.
Thanks for the info. You’ve taught me a lot today.
Are you sure Dr. Francis isn't just talking out of her ass?

Global Warming on Free Republic
Like a study showing the benefits of a rising tide. Then opps, the tide goes out. TOTAL BS.
Hmmm. Does this seem bass-ackwards to anyone else?
See my response at #19. The ice is an insulator over (relatively) warm water.
The warmists are scrambling for study results or analyses to prove that all of this cold weather is the result of warming. It’s the only argument they have left, and the gravy train is slowing down.
They are desperate. I’m sure they applaud every time some “expert” comes out with an analysis like the one in this article. They are hoping against hope that this one, maybe this time, will stick and they can all go back to raking in the cash, getting speaking engagements, getting recognition and Nobel prizes, and getting the prime positions at universities and government jobs.
This particular “expert” isn’t on the same page as the rest of them. That’s what caught my eye. She says explicitly that it’s “too early” to blame this on human activity. 2 decades of climate data are far too little to make such a claim. And unlike the vast majority of her colleagues, she doesn’t do that. This isn’t someone like Algore who would call for legislation after a warm evening.
Seems to me that “global warming” must be self correcting. The warmer it gets, the colder it gets.
Yup... Funny how that works with nary a law or an executive order.

Repeats a pattern seen almost 100 years ago.

So lets say the arctic gets warmer and there is more open water. Then there will be more evaporation and more percipitation will fall somewhere. Enough snow falls and some might stick around all year, as it surely would in Greenland, wouldn’t that build glaciers? Maybe even on the NE of the American continent?
My problem with these kind of articles is that if we are to take the “scientists” as credible, then they should have predicted this sort of model 10 years ago. They just keep modifying the theory to fit the latest weather patterns.
The AGW crowd (who now call it climate change) is stuck on man-made causes for routine climate shifts. Most of them do not acknowledge intelligent design and they refute an idea that is found throughout nature called homeostasis (balance). The earth has been inhabitable for thousands of years because there are larger mechanisms in place that act to prevent large fluctuations in weather. We find in nature a response for almost everything and that principle also exists in our climate.
The mechanisms are macro and micro and we still don’t understand them. The main variable is the radiation from the sun and each day the energy/heat released by man is barely a measurable fraction in comparison to the heat of the sun. They didn’t get it then and they don’t understand it now. The majority of the models simply ignore the sun when truthfully the activities of man have little to do with how much radiation we absorb and no effect on how much we receive.
Man-made climate change is truly about government control and taxation. It is equal parts wealth redistribution and crony capitalism and it has led to some of our most ridiculous ideas - ethanol, wind farms, solar farms, etc etc.
global warming is a hoax and all these scientists and the media are hoaxsters ,criminals, liars and idiots
Warmer Arctic = Colder Winter??
LOLOLOLOLLL.
