It has been four years and...

From The Guardian of September 17, 2012:

Arctic expert predicts final collapse of sea ice within four years
One of the world's leading ice experts has predicted the final collapse of Arctic sea ice in summer months within four years.

In what he calls a "global disaster" now unfolding in northern latitudes as the sea area that freezes and melts each year shrinks to its lowest extent ever recorded, Prof Peter Wadhams of Cambridge University calls for "urgent" consideration of new ideas to reduce global temperatures.

In an email to the Guardian he says: "Climate change is no longer something we can aim to do something about in a few decades' time, and that we must not only urgently reduce CO2 emissions but must urgently examine other ways of slowing global warming, such as the various geoengineering ideas that have been put forward."

A perfect example of a forecast from a computer model - Prof. Wadhams is using a flawed model and he does not check his result with actual data.

First, here is some of that pesky data. The gray line is the average extent from 1981 through 2010. 2016 is the blue line. The width of the gray line represents the value of two statistical standard deviations. The 2016 data looks pretty normal to me - a little bit on the low side but we just had a very large El Niño event and that always affects the Arctic Ice.

Second, remember this story from two days ago: Global Warming Expedition Stopped In Its Tracks By Arctic Sea Ice

And it seems that the good Professor needs to be soundly mocked and driven into the ice-free sea. From the UK Independent of June 4th, 2016:

Arctic could become ice-free for first time in more than 100,000 years, claims leading scientist
The Arctic is on track to be free of sea ice this year or next for the first time in more than 100,000 years, a leading scientist has claimed.

And who is saying this?

Professor Peter Wadhams, head of the Polar Ocean Physics Group at Cambridge University, told The Independent that the latest figures largely bore out a controversial prediction he made four years ago.

What a buffoon in the truest sense of the word!
