This winter's harsh weather and record-setting snow have many asking, what happened to global warming?

Winter officially started a few days ago, but freezing temperatures have paralyzed European travel for weeks. 

"We've reduced the number of flights by European airlines by a third," John Holland-Kaye, BAA commercial director, said. "And that's the first time that's ever been done by any airport in the world."

Now, European Union leadership, which  believes in global warming, wants to know why European airports weren't prepared for what some are calling a new "ice age."

"The vice president wanted to underline that he is extremely concerned about the level of disruption to travel across Europe caused by the severe snow," Helen Kearns, European Commission spokeswoman, said. "Stating very clearly that it's unacceptable and that it should not happen again."

Britain is going through it's worst December since official weather records began.

In the United States, the collapse of the Minneapolis Metrodome roof from too much snow has become a symbol of winter 2010.

In 2002, some climate experts predicted there wouldn't be enough snow in the future for the Winter Olympics, and that ski resorts would be snowless.

Yet, that's currently not a problem in California.

Still, the climate change establishment isn't ready to doubt its own predictions about global warming. Supporters say the record snowfall and cold whether are, in fact, proof of climate change.
