The graph above is the GISS 1200km temperature anomaly profile (by longitude) for March, 2011 at 83N. It shows the entire 83N latitude band at 4.5C – 9.5C anomaly.
This data is completely fabricated. Using 250km smoothing, this is what their profile looks like at 83N.
They have zero data at 83N-90N, yet report very high anomalies – which massively skew the global average upwards.
Hansen has commented in the past that errors in the GISS’s adjusted US temperature data don’t matter to the global average, because the US is only a few percent of the total global area. Certainly this also applies to the Arctic.
This then leads to the question of why Hansen thinks it is necessary to fabricate observational data for a region that is only a few percent of the total global area, especially when there are ways of checking the accuracy of the fabrication.
The fabricated observations are created using a climate model.
Then, the fabricated observations created using a climate model are used to verify the accuracy of….. a climate model!
Hansen’s hubris is becoming legendary.
Chris Y Says: “This then leads to the question of why Hansen thinks it is necessary to fabricate observational data for a region that is only a few percent of the total global area, especially when there are ways of checking the accuracy of the fabrication.”
Because he is a zeolot on a mission, and he can, and has been getting away with it. The adjustments only go one way. He would do much more if he could.
Two points.
1) Shouldn’t the data points at +/- 180 degrees be the same? There,’s are 3.5 degree difference.
2) Chris y, yes it is only a small percentage of the entire globe, but when used an a projection of the world which visually expands the polar areas, it has a huge impact to the unwitting innocent victim of the propaganda.
Yes, and the way temps are grid-extrapolated, the anomaly has a propagative effect on successive adjacent areas. Like a ripple from a rock thrown into a pond, it grows!
the smoothing rests on a single old paper, updated or maybe not really by the same author. Guess who.
“Chiefio’s” been looking at this fairy story too.

The links to GISS are giving me ‘Fatal Error’. Have they been pulled?
No, it was a temporary link which probably expired.
