Experts reconstruct sea surface temperatures off of Norway - evidence confirms this subarctic region was warmer during Roman and Medieval times
Modern warming is not unprecedented as claimed by the IPCC's Climategate "scientists."
"Sejrup et al established exceptionally accurate chronologies for two marine sediment cores raised from the same location on the Norwegian continental margin...they developed the δ18O history depicted in the figure [adjacent], which they use as a proxy for what they call "near surface water summer temperature." And as this history clearly shows, the peak warmth of the Medieval Warm Period was significantly greater than the peak warmth of the Current Warm Period has been to date." [H.P. Sejrup, H. Haflidason, J.T. Andrews 2011: Quaternary Science Reviews]
