In 2008, the US government’s top climate experts announced that the Arctic had passed a “tipping point” and would be ice-free by 2013.
Arctic sea ice thickness is almost exactly the same as it was in 2008, and extent is at a 10 year high. There was no tipping point. It was all nonsense.
So how do they respond to their incompetence? By repeating the exact same lies seven years later.
