I thought the claim was the Arctic was already going to be ice free in the summer by 2013, according to their theory and models. How can there possibly still be ice there 10 years later and melting faster than predicted?
Well, in fact, the actual Arctic sea ice has remained steady since 2007.
Now, it DID DECLINE between the highs back when the first satellite measurements began in 1978-79.
Declined noticeably from (about) 1983 to 2006. Yes, sea ice decreased!
Since 2007 - now 1/3 of the entire 45 year satellite record, SEA ICE HAS REMAINED STEADY.
