I will use the excuse of observing the fifth anniversary (more or less) of former Vice-President Al Gore’s predictions in 2007, 2008, and 2009 that the North Pole would be ice-free by now. Since the North Pole ice cap sits atop open water, I know Santa must have been worried there for a while.
To refresh your memory, HERE is the video of the Goreacle making the prediction to a meeting in Copenhagen of the UN Climate Change Conference in December of 2009.
— UPDATE —
When I posted this initially, the estimates were that the increase in the amount of ice was on the order of 29%. Now, the ice-men have revised their estimates upward markedly, to at least 50% and maybe even 75%.
