    The NAO which is the North Atlantic Oscillation.

    For the past 20 years, the NAO has remained largely positive.

    If you reside in the NE, the NAO has significant impact on your weather.

    Looking at the past few months of NAO fluctuations, you can easily see that when the NAO has been positive, your temperatures have been warmer than "average" and when it has been negative, your temperatures have been colder than "average." During La Nina phases, the NAO being negative means our temperatures are much below "average." During El Nino phases, the NAO being positive means our temperatures are much above "average."

    No greenhouse gasses, no CO2 emissions, absolutely NOTHING to do with Al Gore. A natural meteorological phenomenon that is measured daily.
