Recent temperature extremes at high northern latitudes unprecedented 
in the past 600 years.

  <Summary>
    <Abstract>Recently observed extreme temperatures at high northern latitudes 
are rare by definition, making the longer time span afforded by climate 
proxies important for assessing how the frequency of such extremes 
may be changing. Previous reconstructions of past temperature variability 
have demonstrated that recent warmth is anomalous relative to preceding 
centuries or millennia, but extreme events can be more thoroughly evaluated 
using a spatially resolved approach that provides an ensemble of possible 
temperature histories. Here, using a hierarchical Bayesian analysis 
of instrumental, tree-ring, ice-core and lake-sediment records, 
we show that the magnitude and frequency of recent warm temperature 
extremes at high northern latitudes are unprecedented in the past 600?years. 
The summers of 2005, 2007, 2010 and 2011 were warmer than those of all prior 
years back to 1400 (probability P &gt; 0.95), in terms of the spatial average. 
The summer of 2010 was the warmest in the previous 600 years in western 
Russia (P &gt; 0.99) and probably the warmest in western Greenland and the 
Canadian Arctic as well (P &gt; 0.90). These and other recent extremes greatly 
exceed those expected from a stationary climate, but can be understood as 
resulting from constant space-time variability about an increased mean 
temperature.
