"We analyzed the temperature change of the first decade of the 21st century for Alaska, both for annual and seasonal values. For this study we used all first order meteorological stations in Alaska, which are operated by professional meteorologist of the National Weather Service (NOAA).
 
There are 20 such stations, fairly well distributed over the
different climatic zones of Alaska [1]. We limited our
investigation to these stations, as all of these have similar or
identical in instrumentation and operational procedures. In
Fig. (1) the location of these stations is given.
There are many more climate stations operating in
Alaska, run by different federal, state and local entities as
well as by the industry and private individuals. The quality
of these stations is mixed, but it should not be taken as an
indication that all of these are of poor quality....

1926 was the warmest year ever recorded not only in Fairbanks, but also in
Sitka (southeastern Alaska) and Barrow (northern Alaska),
for which stations the data are available. The mean decadal
temperatures of Fairbanks show for the 1980’s the highest
value (-1.94°C) followed by the 1920’s (-2.39°C) and 1990’s
(-2.59°C). Further, a sudden temperature increase in Alaska
was recorded starting in 1977 [5], seemingly driven by the
change in polarity of the Pacific Decadal Oscillation (PDO)
Index [6], which went from dominantly negative before 1977
to dominantly positive values after that year. An update
version of the temperature trend for the mean of the 20
Alaskan first order stations is presented in Fig. (2), showing
that the temperature increase was non-linear. Besides the
strong temperature increase starting in 1977, on which
Hartmann and Wendler [5] reported, a cooling trend in the
2nd half of the first decade of the new century is clearly visible. 

At this time it cannot be decided whether this is a
climatic shift during the first decade of the 21st century or if
it represents decadal-interdecadal variability."...via Drudge
