I am a co-author of Klemm et al (2013), a paper discussing pollen-transfer functions and a Holocene length reconstruction. Yesterday, I needed to find it to enter it into the Norwegian research reporting system, and discovered that a climate skeptic blog had written about this paper.
“THE HOCKEY SCHTICK” has a post titled “New paper finds another non-hockey-stick in Arctic Siberia”
A new paper published in Palaeogeography, Palaeoclimatology, Palaeoecology reconstructs temperatures in Arctic Siberia over the past 15,000 years and finds another non-hockey-stick with temperatures ~2C higher than the present during the early to mid Holocene [9,000 to 4,000 years ago].
This is followed by a figure showing the reconstructions and the abstract.
Since the sampling resolution of the pollen data is ~200 years, each 1-cm sample spans a couple of decades, and bioturbation reduces the resolution further, it is perhaps not surprising that Klemm et al (2013) don’t resolve a sharp up-tick in the 20th Century.
