Two tenets of AGW theory are 1) tree-ring paleoclimate data reconstructs an accurate portrayal of the climate of the past [except when scientists don’t like what it shows, call it a “divergence problem” and hide the decline] and 2) the poles should show the most warming of all. Unfortunately, the Scots pines in the Torneträsk area within the Arctic Circle in northern Sweden around 68.5°N have not received the memo on AGW as of 2004. A 2008 paper shows that the updated Torneträsk data “show a trend of -0.3°C over the last 1,500 years”. The trees also say that the end of the Little Ice Age in the late 1800’s was the lowest temperature over the past 1,500 years, and according to ice core data was the lowest temperature in the past 10,000 years. By pure chance, this exceptionally cold period is also the same time the global temperature record (HADCRU) begins in 1850. Thus, the global thermometer record showing increasing temperatures in the 20th century mostly represents the recovery from the lowest temperatures of the past 10,000 years during the Little Ice Age. The Torneträsk pines insist that the rate of temperature increase and temperature anomaly of the 20th century was not unprecedented and was less than that of the Medieval Warming Period (~850-1200AD).
