With Such Cold Winters We Can't Have Global Warming - Right?

Have you heard people say that?  That if we have such cold winters we must not have global warming.  It does sound a little confusing.

But as Physorg reports:
While it may seem counter-intuitive, warmer Arctic climes caused by climate change influence air pressure at the North Pole, shifting wind patterns in such a way as to boost cooling over adjacent swathes of the planet.
As global climate change increases, cold and snowy winters will become the rule – just as will violent thunderstorms and massive downpours. The warming atmosphere sucks up more water – then puts it down in the form of more rain, more snow. "The changes are irreversible."

"Cold and snowy winters will be the rule rather than the exception," said James Overland of the US National Oceanic and Atmospheric Administration.

Continued rapid loss of ice will be an important driver of major change in the world's climate system in the coming years, he said at an Olso meeting of scientists reviewing research from the two-year International Polar Year 2007-2008.

The exceptionally chilly winter of 2009-2010 in temperate zones of the northern hemisphere were connected to unique physical processes in the Arctic, he said.

But then again, what do scientist know?  I would much rather believe fortune-tellers, profits, soothsayers and other purveyors of mythology (Bachmann, Palin, Beck, the Pope, televangelist, "healers", and other charlatans, etc.).
