Oh, yes WUWT is really all over this one.

Tick, tick, tick – how long will the new Marcott et al hockey stick survive?

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.

Part I of this series looked at the validity of conclusions for the 11,300 time span covered in Marcott et al. “A Reconstruction of Regional and Global Temperature for the Past 11,300 Years.” This segment (Part II) analyzes conclusions in the Marcott et al. paper in which they contend that “Global temperatures are warmer than at any time in at least 4,000 years” and “Global temperature….. has risen from near the coldest to the warmest levels of the Holocene within the past century.” A heat spike like this has never happened before, at least not in the last 11,300 years”
As in Part I, this segment analyzes the Marcott et al. conclusions using the scientific method of Feynman in which conclusions are checked against well-established data from other sources,. As Feynman points out, if a hypothesis (conclusion) disagrees with observations and data, it is wrong. It doesn’t make any difference how beautiful the hypothesis (conclusion) is, how smart the author is, or what the author’s name is, if it disagrees with data or observations, it is wrong.

Green forces, eager to promote their theories of global warming, appear to be practicing intellectual recycling. Is this the return of the notorious hockeystick – which, in 2001, was the central dogma of Anthropogenic Global Warming (AGW) believers?
This quasi-religious faith in catastrophic AGW still remains a prerequisite for membership in scientific and media elite circles, even in the face of the failure of earlier (model) predictions of apocalypse to manifest, and the admission by an apostle of the faith that for the past 17 years global temperatures have not increased — contrary to the projections of every climate model.
Yes, everyone follow Wayne's suggestion and go to WUWT and read all about it.
