Gergis findings re-surface – the Hockey Stick lives!
By Tony Thomas 31-03-2014
Hello again Hockey Stick, goodbye global Medieval Warming Period.
These are the conclusions of a multi-proxy 1000-year climate reconstruction published today (March 31) in Nature Climate Change, by Dr Raphael Neukom of the Oeschger Centre at the University of Bern, and Dr Joelle Gergis of the University of Melbourne.
Dr Neukom summed up for a University of Melbourne press release:
The study showed the ‘Medieval Warm Period’, as identified in some European chronicles, was a regional phenomenon.
During the same period, temperatures in the Southern Hemisphere were only average. Our study revealed it was not a common climate event that many people have previously assumed.
The paper claims that in 99.7 percent of the results, the warmest decade of the millennium occurred after 1970.
The press release says,“And surprisingly, only twice over the entire past millennium have both hemispheres simultaneously shown extreme temperatures.
One of these occasions was a global cold period in the 17th century; the other was the current warming phase”.”
