Steve McIntyre writes of the curious uptick in the 20th century, which doesn’t seem to be rooted in reality, or to have been in Marcott’s PhD thesis:
While one expects a difference between NHX and SHX in the Holocene, the remarkable difference between NHX and SHX not just in the 20th century, but in the 19th century is a source of considerable interest. According to Marcott, NHX temperatures increased by 1.9 deg C between 1920 and 1940, a surprising result even for the most zealous activists. But for the rest of us, given the apparent resiliency of our species to this fantastic increase over a mere 20 years, it surely must provide a small measure of hope for resiliency in the future.

I think we do somewhat of a disservice to the auditors here and the practices pioneered by Steve McIntyre to suggest that the paper is transparently bad. I don’t think it is, save the hanging blade of the hockey stick and even here many of us are primed to see something funny with such a shape.”
Have you not heard the expression “extraordinary claims require extraordinary evidence?”
Ahhh, so Marcott et al have written a paper that plagiarizes Marcott’s PhD thesis, but they didn’t even manage to get their recycling of their old work right.
So which paper is Marcott planning to retract: the plagiarized one or his thesis?
Maybe the committee should reconsider his doctoral status.
Well tick, tick, tick, indeed. Look also at the dating service information:
