In an effort to save their funding and reputations, climate scientists are currently trying to blame jet stream dips on global warming. But in 1975 scientists knew that they were caused by global cooling.
Science News, Vol. 107
March 1, 1975
During cooler climatic periods, however, the high-altitude winds are broken up into irregular cells by weaker and more plentiful pressure centers, causing formation of a “meridional circulation” pattern. These small, weak cells may stagnate over vast areas for many months, bringing unseasonably cold weather on one side and unseasonably warm weather on the other. Droughts and floods become more frequent and may alternate season to season, as they did last year in India. Thus, while the hemisphere as a whole is cooler, individual areas may alternately break temperature and precipitation records at both extremes. If global temperatures should fall even further, the effects could be considerably more drastic. According to the academy (National Academy Of Sciences) report on climate, we may be approaching the end of a major interglacial cycle, with the approach of a full-blown 10,000-year ice age, a real possibility
Steve,
thanks for this posting. It is a useful counter to the nonsense contained here:
http://www.dailymail.co.uk/sciencetech/article-2757831/Is-global-warming-causing-COLDER-winters-Melting-ice-destabilising-polar-vortex-study-claims.html
In 1975, they blamed the identical phenomenon on excess ice.
In 1975 the political corruption of “science” was in its infancy .
The meandering of the jet stream blamed on a warming arctic is claimed due to less temperature differential between lower and higher latitudes. If the lower latitudes were cooler then, the same less temperature differential existed.
Nonsense. The largest swings in temperature always occur near the poles.
What drives the polar vortex is the difference in temperature between the Arctic and mid latitudes, said Coumou. Once sharp, this differential has blurred in recent years as the Arctic — where temperatures are rising at about twice the global average — warms up, he said.
http://www.rawstory.com/rs/2014/01/the-polar-vortex-scientists-explain-why-global-warming-is-making-winter-colder/
Well these “scientists” say that opposite: http://www.aol.com/article/2014/09/15/global-warming-likely-to-cause-colder-and-snowier-winters/20962706/?icid=maing-grid7|main5|dl9|sec1_lnk3%26pLid%3D529696
“The “polar vortex” that plunged Canada and the U.S. into historical cold last winter is said by researchers to have occurred because melting polar ice changes weather patterns, according to a study published earlier this month.
A team of Korean and American scientists asserted in a new study that the melting ice causes the northern jet stream (upper level air flow) to shift south and bring polar air with it.
The polar ice is melting because warmer water is riding the Gulf Stream (ocean currents) from tropical regions of the Atlantic Ocean to an area north of Scandinavia.”
Rah, they are not saying the opposite. Warmer arctic = less temp differential = meandering jet stream.
Yet we do not have a “polar vortex” every year, so I guess they are still feeling the elephants leg and not realizing what they have.
Global warming CANNOT make winters warmer. But of course some idiot will try to twist the “globe” into just one part of the planet. If there is global warming (by DEFINITION), there is more heat, and less cold. So there is less cold to sink south. Period.
However, if we are experiencing natural variations, then yes, things can happen that will drive some of the STILL frigid air (that cannot possibly exist with global warming since the poles are warming faster) south.
You bleat well for a sheep. You just forgot to engage brain.
No, they’re relieving themselves on our leg and telling us it’s raining.
Polar vortex has been connected to the ozone/Uv interaction aka a sleepy sun.
Here is one paper: http://www.nature.com/nature/journal/v467/n7316/full/nature09426.html
And here is another

A third:
PENN STATE: Ozone depletion trumps greenhouse gas increase in jet-stream shift
I have to go to work so those pointers will have to do.
How does this work when we all know that arctic ice in INCREASING? And yes they did say the opposite. You said: “What drives the polar vortex is the difference in temperature between the Arctic and mid latitudes, said Coumou.”
What those “scientists: said: “to have occurred because melting polar ice changes weather patterns, according to a study published earlier this month……….The polar ice is melting because warmer water is riding the Gulf Stream (ocean currents) from tropical regions of the Atlantic Ocean to an area north of Scandinavia.””
Your warmth is air theirs is water. Your claim is the warmth comes from the mid latitudes and theirs is that it comes from the tropics. Differing bands of latitude. Mid latitude is from 30 to 60 deg. Tropics from 23° 26? 16? N and to 23° 26? 16? (or 23.4378°) S.
rah says “How does this work when we all know that arctic ice in INCREASING?”
rah, While Arctic ice extent is greater than a few years ago, it is less than a dozen years ago:

And it is more than it was 55 years ago. It is called weather and variability.
Bob, you remind me of a fish out-of-the-water. The fish just keeps flopping and flopping, hoping to somehow flop back into the water.
Sometimes it works for the fish, sometimes it doesn’t….
Using “Raw Story” as a source? Seriously?
That doesn’t make any sense. Look at the “Warm “zanal [sic] circulation” winds (left); cool “meridional circulation” figure.
The greatest temperature differential is the one on the right.

I have personally witnessed fifty years of deceptive government science since I started research on “The origin of elements in the solar system” with P. K. Kuroda (aka Kazuo Kuroda) in 1960 and discovered in 1964 that neon isotopes implanted into dark parts of the Fayetteville meteorite by the solar wind had been sorted by mass:
http://www.omatumr.com/Data/1964Data.htm
For the next couple of decades, NASA-funded scientists denied solar mass-fractionation of neon and claimed that data points along the mass-fractionation line were mixtures of Ne-A, B, C, D, etc
See: The neon alphabet game,” Proceedings Eleventh Lunar Planet Sci. Conf. 15, 879-899 (1980); http://www.omatumr.com/abstracts2005/Neon_alphabet_game.pdf
I remember well the warnings of a new Little Ice Age in the mid-1970s and NASA’s scramble to hide evidence in the 1980s and 1990s that the Sun’s pulsar core made our elements and birthed the entire Solar System in a supernova explosion five billion years (5 Ga) ago:

Government deceit became even more obvious after the Climategate emails surfaced five years ago, in late November 2009.
My question, Steven (aka Tony), Where is the statesmanship to lead society back to sanity?
The best hope I have found is the Ron Paul Institute for Peace and Prosperity, but Ron is almost as old as me! http://ronpaulinstitute.org/
This paper gives a summary of sixty-eight years of government deception about the source of energy in cores of heavy atoms and stars, from 1946 until 2014.

Hello Oliver,
I’m sure a lot of us can empathize with your question. I’ve thought about it for a number of hours, and gone over about a dozen possible answers in my mind. In my opinion, the best answer to your question is this. There are still smart people to be found in positions of power, many of them behind the scenes. But it’s rather difficult for those leaders to lead a generation of people in a new direction when they’ve been leading them in the opposite direction for so many years, and scrambling the brains of that generation in a misguided belief that they must “fundamentally transform” the culture. Rest assured that there is evil, an evil force, behind the mistakes that have been made. And that same force has a degree of power to prevent attempts to correct the erroneous course on which we’ve been heading.
I look at Ron Paul and I think to myself:
I look at Ross Perot, and I think:
I look at Reagan, and I think:
These are just three examples, and I could cite others of people who were personally close to me, but these ones illustrate my point … which is that those leaders with the ability to envision a powerful strategy for correcting some of the damage, and the skill to implement that strategy … have strong disincentives to act on their ideas.
Bear in mind that the United States is not an island unto itself, but is part of a global power structure, and for it to try to go in the opposite direction as that global structure is going … is about as easy as rowing upstream in the Mississippi with only one oar.

For years those who tried to warn of a ‘New World Order’ were called Conspiracy Nuts and worse. Now we have global Leaders like former WTO Director-General Pascal Lamy coming right out and saying. “The reality is that, so far, we have largely failed to articulate a clear and compelling vision of why a new global order matters” and that the agreement was made among world leaders in the 1930s “that the road to peace lay with building a new international order…”
The fact that world leaders are now coming right out in the open and saying that behind the scenes they WERE building a global government scares me to death.
“For more than a century ideological extremists at either end of the political spectrum have seized upon well-publicized incidents such as my encounter with Castro to attack the Rockefeller family for the inordinate influence they claim we wield over American political and economic institutions. Some even believe we are part of a secret cabal working against the best interests of the United States, characterizing my family and me as ‘internationalists’ and of conspiring with others around the world to build a more integrated global political and economic structure–one world, if you will. If that’s the charge, I stand guilty, and I am proud of it.”
? David Rockefeller in his 2002 book entitled “Memoirs”
Yes, we were called that, weren’t we? Nowadays, they usually let us say whatever we want, quote their statements or whatever, and then just give us the silent treatment. Surprisingly effective, too! This generation doesn’t even need ad hominem to follow the prescribed path. All they need to see is a leader ignoring his critics, and they just follow suit. Very well-programmed people!

Hubert Lamb proposed this hypothosis at about that time. In cold times, the jet stream produces more waves than warm periods. Quote.
Reblogged this on the WeatherAction News Blog.
We have a blocking high developing over the Arctic basin this week which will allow temps to drop pretty good. Canadian Ice Service starting to show new ice formation in various places in the Archipelago and even starting in the Beaufort. These blocking patterns do cause weather extremes, and they have been doing so for as long as the Earth has been here. This year and last, we have seen some cooler summer temps in the Arctic overall, and temps this month are dropping pretty quickly.
Another note is the cooler waters in the Hudson Bay, Barents, and Kara seas. Ice could form a little quicker in these areas this Fall. The Summer pattern kept these areas from getting too warm unlike the past few years because of blocking patterns favoring more northerly winds. Looking for that this Fall again.
http://weather.unisys.com/surface/sst_anom.gif
Where do Unisys get the data to create these charts? I’ve noticed that the range – high to low – has progressively increased over the years. The ranges now are often infeasible – somewhere on that chart is a sea surface temperature 16.2°C below the mean and somewhere else there is a sea surface temperature 27.1°C above the mean. These are both infeasible temperatures for Earth (assuming the mean is ~14°C. What is going on?
At first glance it looks like the same or similar colors repeat four times, so it looks like it is meant to be confusing.
A major difficultly in human thought is that we have to blame any event on a slngle happening.
I would suggest considering the idea that earth’s climate happens from the confluence of many things in many different cycles.
If the timing is correct we can have a major shift in climate, but mostly we have negative feedbacks which keeps the earth closer to equilibrium, although I do not think we ever get there.
CO2 is a minor player and really the system is so complex that for anyone to say they understand it completely is being a fool
Even the IPCC admitted the climate is ‘Chaotic’ (as in chaos theory) and therefore CAN NOT BE MODELED. (I have the quote stashed somewhere.)
Dr. Brown has suggested that at this point the climate oscillates between two ‘Strange Attractors’ but in the distant past there seems to have been three.
We can model out about three days and if we are lucky around five. After that it is a crap shoot because the outcome is very sensitive to the initial state and we do not yet know the unknown unknowns much less the exact values for the parameters we think we know.

We are know thanks to the Milankovitch Cycles (and Lisiecki and Raymo’s 2005 rebuttal of Loutre and Berger’s 2003 astronomical model) we are in the transition zone for switching from the warm interglacial to glaciation. We haven’t the foggiest idea of what actually kicks the earth from the one Strange Attractor to the other. This is where the focus of Climate Science should be not on Gore Bull Warbling and wasting tax payer money on bird smokers and bat-chomping, bird-slicing eco crucifixes.
On the other hand if the elite do know what kicks the earth into glaciation and they know it will happen soon, sucking as much wealth out of northern countries and buying large swaths of southern land makes sense…..

Given that the jet stream always sits above and between air mass cells, in this case the Mid-latitude Cell and the Polar cell, and is at the junction between the top of the troposphere/tropopause/stratosphere, where the ozone layer is; this is where the air circulations differ rapidly (in composition, temperature, pressure, humidity, and wind velocity and direction) as you cross any of these boundaries – is it not about time that more empirical research was done on this phenomenon?
Human knowledge of why the jet-stream exists, and reasons for its movement are missing – regardless of what ‘scientist’ say. If there were an understanding of this effect then jet-stream ‘wobbles’ would never be a surprise, and to some degree would be predictable.

Especially the winds at the poles.

SEE: slides 16 on especially #27 and #32
Before Solar Cycle 24 the jets were more zonal due to the widening of the ‘tropical belt’ Now we see the tropical belt narrowing and the jets going more meridional.
This is an older study (2007) about the widening of the tropical belt. Solar Cycle 24 began January 4, 2008. Cycle 23 was relatively active until ~ January 2006. So it was before the sun went into a funk.

I think it is strange that the jet-stream goes loopy after NASA reported that the stratosphere/thermosphere had reduced. Sorry I haven’t a link, I’m trying to remember where I saw that – it was just before the jet-stream was reported to have moving.
But the change in the jet stream just couldn’t be caused by changes in the sun…. NAH, it is all the fault of the added 3 ppm of CO2 from humans since 1958!
Per the IPCC, 4% of annual emissions are from Mankind, with 96% coming from natural sources. So mankind gets the blame based on 4% of the annual emission or ~ 4% of (400 ppm minus 315 ppm) = 3 to 4 ppm change in 56 years at the point where the log curve is going flat……
It’s obvious innit.
The meander waves caused by warming are in anti phase to those caused by cooling. The amplitude is the same though.
