Record Antarctic Ice Due to Global Warming?

Ice around the South Pole has expanded to cover a record area, scientists revealed yesterday – a month after saying that the North Pole had lost an unprecedented amount of its ice.

Researchers say – rather confusingly – that both occurrences are down to the ‘complex and surprising’ effects of global warming.

The record Antarctic sea ice cover was revealed in satellite images from the US National Snow and Ice Data Center in Colorado.
Oops. Gotta come up with something quick. How about this:
In the Arctic, the amount of sea ice is governed by the temperature of the sea and air around it.

But in the Antarctic, what matters is the wind. Changes in the strength and directions of the wind over the last few decades appear to be pushing the ice further out to sea.

Researchers believe climate change has created a ‘wall of wind’ that keeps cool weather bottled up in Antarctica while the rest of the planet is warming.
Wattsupwiththat explains the "thinning" Arctic ice sheet here, as well as the selective use of data from an area dictated by then-Senator Gore.
