Iceland Adjustments Spread To Norway And Russia

We have already seen how GHCN recently introduced a tranche of temperature adjustments for most stations in Iceland and Greenland that had the effect of cooling the past and/or warming the present, thereby creating a false warming trend. Further investigation shows that similar adjustments have been made for many other stations, ranging from the Shetland Islands through Northern Norway and onto much of Russian arctic coast.
Ostrov Dikson, an island just off the Russian coast in the Kara Sea, is one of these and the adjustments, as shown above, have resulted in 2011 being about half a degree warmer than any other year on record. Previously both 1943 and 1945 were warmer.
So far I have found similar changes at the following stations :-
Jan Mayen Island
According to GHCN, these adjustments, on a global scale, are insignificant. However, all the stations are inside or close to the Arctic Circle, and as there are no other stations between them and the North Pole they are used to estimate temperatures across a large swathe of the Arctic, from Nuuk in Greenland, 51o West, to Dudinka 86o East, a sweep of 137 degrees. More than a third of the Arctic is potentially affected by these adjustments.
According to GISS, the Arctic is the fastest warming place on the planet, even though they have no actual temperature data for most of it. Their map shows just how little coverage they have, even allowing for a 250 km projection.
Now it appears that even the little data they have is corrupted. Meanwhile GHCN continue to prevaricate and Hansen plays with his pink crayon.
