    freezing behinds off because of global warming.

    right, OR?

    And last year the east and southeast of the US had extreme snow events.

    One of the primary predictions of global warming is wider and wilder weather swings, with an overall warming. And that is exactly what we are seeing. Now if we were seeing months where the average global temperature was the tenth or twentieth coldest on record, you might have a case that global warming was slowing, or even going the other way. But what we are seeing, is that even with two La Nina's back to back, the worst that we got for January was that it was between the 20th and 30th coldest on record.

    Frankieboy, when we get a decade that is about in the middle of the decades on record, then you can flap yap. Until then, as long as each decade is warmer than the last, we are most definately in a warming trend.

    Okay.

    Hey EUROPE! There appears to be something going on that some people are calling global warming.

    FWIW, I think we ought to call it GLOBAL WEIRDING as one of the things that result from this Global Weirding event is wider and wider swings in the jet stream that often result in very harsh winters and very hot summers.

    Actually the extreme winter weather in Europe fits in with the climate scientists' predictions as to what would happen as the Arctic ice cap melts away and exposes the warmer ocean waters to the air.

    Science behind the big freeze: is climate change bringing the Arctic to Europe?
    A loss of sea ice could be a cause of the bitter winds that have swept across the UK in the past week, weather experts say

    The Independent
    04 February 2012
    (excerpts)

    The bitterly cold weather sweeping Britain and the rest of Europe has been linked by scientists with the ice-free seas of the Arctic, where global warming is exerting its greatest influence. A growing number of experts believe complex wind patterns are being changed because melting Arctic sea ice has exposed huge swaths of normally frozen ocean to the atmosphere above. In particular, the loss of Arctic sea ice could be influencing the development of high-pressure weather systems over northern Russia, which bring very cold winds from the Arctic and Siberia to Western Europe and the British Isles, the scientists believe. An intense anticyclone over north-west Russia is behind the bitterly cold easterly winds that have swept across Europe and some climate scientists say the lack of Arctic sea ice brought about by global warming is responsible.

    "The current weather pattern fits earlier predictions of computer models for how the atmosphere responds to the loss of sea ice due to global warming," said Professor Stefan Rahmstorf of the Potsdam Institute for Climate Impact Research. "The ice-free areas of the ocean act like a heater as the water is warmer than the Arctic air above it. This favours the formation of a high-pressure system near the Barents Sea, which steers cold air into Europe." Studies by scientists at the Alfred Wegener Institute for Polar and Marine Research have confirmed a link between the loss of Arctic sea ice and the development of high-pressure zones in the polar region, which influence wind patterns at lower latitudes further south. Scientists found that as the cap of sea ice is removed from the ocean, huge amounts of heat are released from the sea into the colder air above, causing the air to rise. Rising air destabilises the atmosphere and alters the difference in air pressure between the Arctic and more southerly regions, changing wind patterns.

    Professor Rahmstorf said the Alfred Wegener study confirms earlier predictions from computer models by Vladimir Petoukhov of the Potsdam Institute, who forecast colder winters in western Europe as a result of melting sea ice. Dr Petoukhov and his colleague Vladimir Semenov were among the first scientists to suggest a link between the loss of sea ice and colder winters in Europe. Their 2009 study simulated the effects of disappearing sea ice and found that for some years to come the loss will increase the chances of colder winters.

    Wider swings is a "Primary predication"? Really? Since when?

    How does this work in a lab, because it sounds like you just make it up as you go
