Tony Heller - Right Where He's Always Been

More of Tony Heller / Steve Goddard's seeming inability to read graphs.

In Arctic Summer Crashes And Burns he claims, amongst other things, that

Arctic sea ice extent is right where it always is this time of year.

Illustrated with this graph.

On that graph, current sea ice is marked with a red dot, clearly showing it very similar to where it was this time last year, below where it's been for the two years before that, and way below (almost 2 million km2 below) the 1981 - 2000 average. In fact it's not even within 2 standard deviations of the average.
