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:
In introducing the report of their study, Esper et al. (2012) write that millennial-length temperature reconstructions have become “an important source of information to benchmark climate models, detect and attribute the role of natural and anthropogenic forcing agents, and quantify the feedback strength of the global carbon cycle.” And, therefore, the four researchers have dedicated themselves and their talents to developing the most reliable long-term regional temperature reconstructions possible, focusing their attention most recently on parts of northern Sweden and Finland.
The study analysed living and sub-fossil Pinus sylvestris trees, Scots pines as they are more usually called.
Scots pines are long lived trees usually 150-300 years, though there are some that have lived for 700 years in Scandinavia.
In considering the authors’ findings with respect to the purpose of this review, the four researchers say that the new temperature history “provides evidence for substantial warmth during Roman and Medieval times, larger in extent and longer in duration than 20th century warmth.” Once again, therefore, as ever more data-inclusive and carefully-analyzed studies of palaeotemperature proxies are conducted, it is becoming ever more evident that there has not been anything unusual, unnatural or unprecedented about either the rate of warming or the level of warmth achieved during the 20th century, which further suggests that there is no real-world empirical evidence for any CO2-induced global or regional warming. It has all been natural.
It has all been natural, recently the weather soothsayers at the UK Met Office
quietly stealthily released data that shows conclusively that there has been no warming for the last 16 years.
The warmists would have us all believe that the pause in their Global Warming wet dream, which has lasted for the same duration as the warming did, is of course caused by Anthropogenic Global Warming and that we must commit economic and democratic suicide and adopt the Green Agrarian Dream to prevent an increase of more than 2 C.
