Okay - so they change the way sea ice is calculated. Got it. If you compare last years method with this years it looks like sea ice is increasing, but if you compare apples-to-apples, you see that its really isn't. But this map apparently only shows data up to 2010 (WTF?) when minimum ice levels were apparently reached in 2012.
Don tinfoil hats and flame retardant suits as required.
