Daily Mean Temperatures in the Arctic 1958 - 2010
Daily mean temperatures for the Arctic area north of the 80th northern parallel, plotted with daily climate values calculated from the period 1958-2002.

Frank Lansner hidethedecline.eu/pages/posts/colder-arctic-temperatures-in-the-melt-season-vs.-giss-temperatures-188.php has plotted this data for the melt season since 1958 in the form of a graph. He states:
DMI data show that Arctic 80N-90N temperatures in the melt season this year is colder than average. This was the case last year too, while earlier years in the DMI analysis period (1958-2010) hardly ever shows Arctic melt season temperatures this cold.
This is how DMI temperature averages for Arctic 80N-90N melt season appears when plotted to allow comparison over time:
(When i speak of “the melt season” i refer to the period where temperatures 80N-90N are above zero Celsius. The green line above is the DMI temperature average, a little over 0,9 Celsius)
It seems that average Arctic temperatures 80N – 90N in melt season of the years 2004, 2009 and 2010 are around 0,4-0,5K whereas the temperatures in 1991 and 1993 where around 1,3 K. In general DMI´s data (if correct) reveals a cooling from the mid 1990´ies till today.

Is it possible that Hansen at NASA/GISS can be showing an ever hotter Arctic anomaly when the actual summer temperatures there, according to the DMI, are apparently falling over time?
Interesting.
