Nobody lied about global warming... Bill8 explained it basically...
But I will make it simpler for the GFY brain
Northern/Western European cold and snow winter 2010/2011 explanation with global warming:
Global Warming -> Ice Melts -> Melted Ice Water cools oceans -> Gulf stream cools down -> Gulf stream heats air less than in 2009/2010 ->Europe gets colder air -> Europe gets colder
There, simple huh?
