Martin P. Tingley & Peter Huybers
Nature 496, 201–205 (11 April 2013) doi:10.1038/nature11969
Using a hierarchical Bayesian analysis of instrumental, tree-ring, ice-core and lake-sediment records, they show that the magnitude and frequency of recent warm temperature extremes at high northern latitudes are unprecedented in the past 600years.
