Now, evidence has been supplanted by hard scientific fact. All four major global temperature tracking outlets (Hadley, NASA's GISS, UAH, RSS) have released updated data. All show that over the past year, global temperatures have dropped.

The cold waves were certainly was not even remotely predicted by any of the global climate models that the IPCC uses to assess future climate change.
But, why has this winter been so cold? Besides potential large scale effects such as changes in the sun or the earth's orbit which I am not well informed, the two things I can point to are La Nina and a record amount of sea ice in the Antarctic. But he year could still turn out warm of course, because we have only been through 2 months. But, if the cooler trend continues it will force many "Global Warming" theorists to re-think on their theories. And it makes you wonder about the "Global Warming" movement in general, and climatologists must head back to the forecasting computers and figure out what major piece of the climate puzzle was unaccounted for, that caused such a severe error in future projections.
