Just when you think the bottom of the Hockey Stick rabbit hole has been reached, Steve McIntyre finds yet more evidence of misconduct by the Team.
The research was from Briffa and Osborn (1999) published in Science magazine and purported to show the consistency of the reconstruction of past climate using tree rings with other reconstructions including the Mann Hockey Stick. But the trick was exposed in the Climategate dossier, which also included code segments and datasets.
In the next picture, Steve shows what Briffa and Osborn did not only did they truncate their reconstruction to hide a steep decline in the late 20th Century but also a substantial early segment from 1402-1550.
As Ive written elsewhere, this sort of truncation can be characterized as research misconduct specifically falsification. But where are the academic cops? Any comment from Science magazine?
Steve also discusses the code underlying the plot and you can see how the truncation is a clear deliberate choice not something that falls out of poorly understood analysis or poor programming.
