In the 1970’s, The Polar Vortex Was Caused By Global Cooling.

The claims that the Polar Vortex, that has brought the cold winter in the States and wet weather to Britain, is linked to global warming are based on the theory of a weaker jet stream. The idea is that,as the Arctic warms, the temperature differential between high and mid latitudes decreases. As the jet steam is powered by this differential, the theory goes, the jet stream is liable to turn from a powerful polar or zonal flow to a slower meridional one.

Just imagine a slow moving river, and think of how it meanders in comparison to a fast moving one. The theory sounds superficially attractive, until one realises that such events have occurred regularly in the past.

Back in 1975, C C Wallen, Head of the Special Environmental Applications Division of the World Meteorological Organization, had this to say about the consequences of the cooling trend since 1940:

 

The principal weather change likely to accompany the cooling trend is increased variability-alternating extremes of temperature and precipitation in any given area-which would almost certainly lower average crop yields.

During cooler climatic periods 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.

 

 

And he even gave us these diagrams.

Now, Wallen may have been right about the causes, or he might have been wrong. But what is clear is that the existence of similar jet stream conditions 40 years ago utterly discredits the theory that they now have something to do with global warming.

Unfortunately, today’s tabloid climatologists are so fixated on the idea that CO2 is the cause of everything nasty, that they don’t seem to want to learn from the past.

It’s rather sad really.

    Paul they don’t learn from the past because it isn’t relevant to their religion. No straw is left unclutched as the world refuses to burn up to the dictats of their high priests. The way anything proves the CO2 theory is, in itself, clear proof of large dollops of steer droppings being issued from Warming Central for all the foot soldiers to grasp onto.

    Once again I recommend Rupert Darwall’s book “The Age of Global Warming”. Anyone who reads this well researched and bibliographed book and still thinks science is behind the Climate Change campaign really is on the Kool-Aid.

    Paul not sure if you’ve seen this before.

    Funny that. I’ve been leaving messages on this facebook page https://www.facebook.com/YearsOfLiving until they finally got round to blocking me which is nice.
    Their latest piece covers the polar vortex with a handy comic illustration.
    It’s true that whenever you point out the shortcomings of their position or the extreme shortcomings and hypocrisy of those featuring in their television series they go on the offensive hurling abuse.
    Funny old world eh?

    I’ve been telling you all just that for several years:

    but have moved on and created a new description as to how the system must work.

    Thanks, Paul.
    Yes, it is sad when science is distorted to accommodate politics and destroy reputations.
    I think this state of affairs might be the precursor to a scientific revolution.
    And thanks for the link to the 1975 Douglas piece and the Wallen diagrams.

    I think the unusual storm damage this year on the South coasts of England and Wales was not just that the storms kept coming (way more than normal), but that some of them involved Southerly winds, which is quite unusual. The more usual sou’westers are relatively harmless.

    ”Polar Vortex” is: when extra cold / HEAVY air is puled away from the polar caps, by the earth’s centrifugal force

    Weather is caused by the temperature difference between the poles and the tropics. The higher the difference the more energy available for weather so cold temperatures foster violent storms. The reason why our worst weather is in the winter. The Jet Streams are powered by energy transfer as well not as the Climateers seem to try to fit to their GHE theory. It is not temperature as much as energy which only comes from the sun.
