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
The Climate Was Hotter In Roman & Medieval Periods
Nature Climate Change, the cooling effect of orbital shifting on the climate has been up to four times as powerful as anthropogenic (human-caused) warming pressures
The denial by warming alarmists of a hotter climate in Roman and Medieval times has long been a central foundation to support the flawed theory of Anthropogenic Global Warming.
According to hockey stick creator Michael E Mann, the Medieval Warming Period (MWP) was a localised event, if indeed the MWP actually happened for Michael Mann at all.
New research has found that the MWP reached as far as Antarctica, as an indicator atmospheric levels of CO2, at the time were around 250 ppm, as opposed to 393 ppm today. Greenland (the clue is in the name) was not always covered in ice as it is today, between 982 AD – 1500 AD the Vikings farmed Greenland, in recent times Viking Farms have been found frozen in the permafrost.

The Medieval Warming Period Was Much Warmer Than It Is Today
New EU Research: Medieval Unprecedented Warming Period temps robustly higher - by 1.2 degrees
A new EU study of global warming between 900 AD and 2002 shows beyond doubt that despite lower levels of atmospheric CO2 global temperatures were significantly higher than they are today.
This is yet another study that shows junk scientist Michael E Mann and his “hockey stick” are wrong.
The myth of the hockey stick lives on despite the IPCC subsequently distancing themselves from Mann and his ability to hide the decline. Read the rest of this entry
