GISS shows June anomalies north of 80N from 0-5 to 4C. They depend heavily on those large North Pole numbers to bring the global average up.
A couple of minor problems.
- It is impossible to get those sort of anomalies over the ice pack in summer. Temperatures over the ice are buffered by the latent heat of melting.
- Actual measured temperatures show that June was below normal north of 80N.
So where do the GISS numbers come from? They pull them out from where the sun never shines, because they don’t have any thermometers north of 80N.
