Northern Scandinavian Forests Confirm Roman & Medieval Warming Periods

A new peer reviewed study has just been completed Variability and extremes of northern Scandinavian summer temperatures over the past two millennia by scientists from the Johannes Gutenberg University, Swiss Federal Research Institute, Finnish Forest Research Institute and the Oeschger Centre for Climate Change Research which confirms the existence of both the Roman Warm Period (RWP) and Medieval Warm Period.

A believable Climate computer model must be able to reconstruct past warming and cooling events, after all, if the computer model cannot recreate the past reliably then it’s future predictions are going to be significantly different to the observed reality, as is the case with the current generation of computer climate models.

The need to benchmark and calibrate the computer climate models against recorded real world temperatures is recognised by the authors of the study: Read the rest of this entry
