    Global Warming believers tell us that this cold spell most of us have been having actually proves global warming.

    I don't recall another theory where an outcome is proven by the exact opposite outcome. So I thought it might be fun to come up with some... in a mocking kind of way.

    Maybe I didn't explain this very well... but lets have a go. This thread might be a bust, if so.. my apologies.

    A cold spell in mid-latitudes, a very warm spell in the Arctic.

    Unusual Arctic warmth as north hemisphere shivers | Reuters

    Northern Hemisphere has shivered in a cold snap in recent weeks, temperatures in the Arctic soared to unusually high levels, U.S. scientists reported.

    This strange atmospheric pattern is caused by natural variability and not by rising levels of greenhouse gases. However, it could affect Arctic ice which in turn may impact global warming, said Mark Serreze, director of the U.S. National Snow and Ice Data Center in Colorado.

    "It's very warm over the Arctic, with air temperatures locally at 10 to 15 degrees F (5.6 to 8.4 degrees C) warmer than they should be in certain areas," Serreze said in a telephone interview on Monday.

    This contrasts with record or near-record cold over much of the eastern United States and Canada, Europe and Asia for the last two weeks of December and the first days of January, the data center reported.

    It's due to a large area of high pressure over the Arctic, and a big area of low pressure at the mid-latitudes, where much of the Northern Hemisphere's population is concentrated.

    Usually these areas of differing air pressure would shift and mix in a phenomenon known as the Arctic oscillation. Instead, they've remained stationary in what scientists term a negative phase of the oscillation. A positive phase would have low pressure over the Arctic and high pressure over the mid-latitudes.

    Serreze said that as of December, the oscillation was in the most extreme negative phase seen since modern record-keeping began in 1950.

    "Normally the circulation of the atmosphere would mix these two (areas of varying air pressure) together, and it's not doing a very good job of that right now, so we have these blobs of warm air over the Arctic and these blobs of cold air over the mid-latitudes, just sitting there," he said

    Well it is common sense that since it's warmer in the Arctic the cold must have come south for the winter.

    And in 2009, what planet were you on?

    Report: 2009 was a warm year in USA - USATODAY.com

    By Doyle Rice, USA TODAY
    Despite an unusually chilly year in the Midwest, the national U.S. temperature was slightly above average in 2009, according to the National Climatic Data Center.
    This marked the 13th consecutive year the nation experienced a warmer-than-normal average temperature. Since the late 1980s, 21 of the last 24 years have been unusually warm in the USA. Beginning in late 1800s, when accurate weather records began, the country has been warming at a rate of about 0.1 degree per decade, according to the climate center.

    Overall, the nation measured 53.1 degrees for the year, which ranked it as the 35-warmest year on record. The long-term average is 52.8 degrees.

    The climate center reported that while much of the central Plains and Midwest had below-normal temperatures in 2009, the coolness there was counterbalanced by above-average readings in parts of the South, Southwest and West.

    Precipitation was more of a story than temperature in many locations. Three states –Illinois, Arkansas, and Alabama– slogged through their second-wettest year on record. Meanwhile, six other states had one of their top 10 wettest years ever recorded: Delaware, Maryland, Virginia, Georgia, Mississippi, and Missouri.

    Switchboard, from NRDC :: Dan Lashof's Blog :: More on 2009 Global Temperature Data

    Looking deeper into the data does reveal some interesting differences between the NASA and NOAA time series, which are most likely due to slightly different approaches to combining all the individual weather station data to obtain a global average. In the NASA-GISS time series 2009 is tied for the second warmest year on record with 1998, whereas NOAA pegs it as tied for 5th. (Both NOAA and NASA rank 2005 as the warmest year, in contrast to the UK Met office which ranks 1998 as slightly warmer.) Hansen’s post estimates that the uncertainty in determining the global average temperature in any one year is 0.025ºC (one standard deviation). Taking this uncertainty into account, 1998, 2002, 2003, 2006 and 2007 are in a virtual tie with 2009 for second warmest in the GISS data series. Similarly, 2002, 2006, 2007 and 2004 could all be considered to be in a statistical tie with 2009 for third warmest in the NOAA dataset.

    Re-read the Op and take it elsewhere, This is supposed to be a lighthearted thread not one for your Global warming propaganda.
