30-yrs of global....cooling?

[Wagner]

Wait, Al, I'm confused...I thought the planet was warming? I'm pretty sure I heard all the 'scientists' saying that...ya know, the planet is 3 degrees warmer than it was 190yrs ago..or something.

Pretty sure CNN has a whole series documenting the "Planet in Peril" hmmm.

Wait, are they back on cooling again? Didn't they say that back in the 70's too?

Those damn high pressure ridges in the Arctic:



Feeling That Cold Wind? Here’s Why.
By KENNETH CHANG

Published: January 9, 2010




A bitter wind has been blowing over parts of North America, Europe and Asia. Some places have been colder than ever, like Melbourne, Fla., which dipped to 28 degrees last Thursday, a record low. Europe has been walloped by snowstorm after snowstorm.





What’s going on? Global cooling?
Nope. A mass of high pressure is sitting over Greenland like a rock in a river, deflecting the cold air of the jet stream farther to the south than usual.

This situation is caused by Arctic oscillation, in which opposing atmospheric pressure patterns at the top of the planet occasionally shift back and forth, affecting weather across much of the Northern Hemisphere.

What’s notable this year is that the pattern of high pressure over the Arctic is more pronounced than at any time since 1950.

In most years over the past few decades, the opposite has been true: there has been lower-than-average pressure over the Arctic, and higher-than-average pressure over the mid-latitudes — the middle of which cuts through Maine, across the Great Lakes and on to Oregon.

That pattern allows the jet stream to blow unimpeded from west to east and keeps the cold Arctic air largely north of the United States. The result tends to be warmer temperatures across much of the United States east of the Rocky Mountains.

No one is quite sure what drives these flip-flops in air pressure.
“I tend to think of it as a random thing,” said John M. Wallace, who is a professor of atmospheric sciences at the University of Washington. “I don’t think we understand any reasons why it goes one way one year and the other way another year.”

What does seem clear is that these oscillations have nothing to do with global warming, or, for that matter, global cooling. For one, they’re not new. And this winter’s cold has not been global. Santa, by North Pole standards, has been experiencing a balmy winter.

“Pretty much all of the Arctic is above normal,” said Dr. Walter Meier of the National Snow and Ice Data Center in Boulder, Colo. In some areas, the temperatures are as much as 15 degrees Fahrenheit above normal.

In terms of global average temperature, this winter’s arctic oscillation “probably roughly cancels out,” Dr. Meier said. (In fact, last year ranked as the fifth-warmest year on record since 1850, the United Kingdom’s Met Office says.)

And it is certainly not the coldest air that has descended on the United States. In a great blizzard that swept across the East Coast in 1899, even parts of Florida dropped to below zero.
“We’re not close to those types of things,” said Michael Vojtesak of the National Weather Service.

Just goes to show there are MANY variables which make up our weather patterns. One major variable often overlooked by the doomsayers of global warming is that glowing ball of fire in the sky. Sure...We should work to keep global pollution down to a minimum; but don't bring down the economy in a knee jerk reaction to something science has yet to fully understand.

I just love how this cold weather pattern coincided with that freak show circus in Copenhagen.

I think the truth about global warming probably lies somewhere between Wagner and Mr. Gore's opinions. A few cold winters don't disprove anything. Big picture...big picture.

Wait , what , we are on this topic again .
I am not going to drag out some long winded scientific documents , I happen to know that some of this weather shenanigans is caused by the Earths magnetic field fluctuating , this affects El Nino and other stuff .

You guys need to pay closer attention to the news...
Clearly the mass effect of the dreaded Mad Cow epidemic from a few years ago, has significantly reduced the amount of methane gas in the atmosphere thus minimizing the greenhouse effect and causing temperatures to drop recently.
Not to worry though because the global mass effect of the latest science backed media scare about H1N1 should have enough people on the planet all running a fever at the same time, inevitably raising the ambient temperature to above average any day now.
Stay tuned and believe everything you hear in the news, read in the scientific literature and are told by your mechanic. They must know what they are talking about, they are employed and get paid, right?

nice pull MD...so if it is cold it is global warming and if it is warm it is global warming. Sounds like a win/win for the environmentalist industry..woohoo.

Point is, it is BS to change your entire way of life (or a nations), go in debt and stop the world on this bogus research

My feet are cold. I could stand some warming right now. Anybody got Al Gore's number handy?
