Brrr, it's cold in the Antartic

But not as cold as it used to be. To many in the church of climate change denial ("climate scientologists" I think Curly calls them), Antarctic cooling has been the elephant in the room. To many deniers, a gap in scientific knowledge on the issue discredits anthropogenic global warming. Even climate scientists have acceded the point that there was a gap. Honestly reviewing the issue, the IPCC concluded in 2007 that:
"It is likely that there has been significant anthropogenic (human-induced) warming over the past 50 years averaged over each continent - except Antarctica."
Whilst some parts of the Antarctic have been getting cooler, the average across the continent shows a warming trend over the last 50 years. But those pesky scientists at who prepared the work and have submitted their paper to Nature have been cautious in pointing out that:
"Our paper — by itself — does not address whether Antarctica’s recent warming is part of a longer term trend."
But it does address that gap in the IPCC's 2007 assessment.

It looks more than ever that the denial position is to climate science as the desperate "God of the gaps" philosophy is to physics and biology.
