Hansen shows the region north of 80N red hot (1958-2002 baseline) in July, even though he has essentially no data there. DMI shows temperatures in July almost exactly normal.
If Hansen actually knew anything about the Arctic, he would know that having an anomaly of +4 degrees over the ice sheet during the summer is almost impossible. The latent heat of melting ice holds the temperature very close to freezing over the ice during the summer. But he needs those big Arctic numbers to keep the global temperature up close to scenario C – the zero emissions scenario.
