Bryan Shuman, a UW professor in the Department of Geology and Geophysics, and Jeremiah Marsicek, a recent UW Ph.D. graduate in geology and geophysics, led the new study that is highlighted in a paper, titled «Reconciling Divergent Trends and Millennial Variations in Holocene Temperatures,» published today (Jan. 31) in Nature.

That assumption conflicts with studies finding that the Northern Hemisphere was warmer than present for several decades during the Medieval Warm Period and Roman Warm Period and for thousands of years during Holocene Optimum. (globalwarming.org)
This is a possibility in the abstract, but the present behavior of the climate system, the behavior of coupled atmosphere - ocean models in modern conditions, and the record of Holocene climate changes do not give any hint that such a thing occurs. (realclimate.org)
