In a belatedly-posted FAQ to the paper, which appeared on Real Climate earlier today,Marcott et al. make this startling admission:

Q: What do paleotemperature reconstructions show about the temperature of the last 100 years?

A: Our global paleotemperature reconstruction includes a so-called “uptick” in temperatures during the 20th-century. However, in the paper we make the point that this particular feature is of shorter duration than the inherent smoothing in our statistical averaging procedure, and that it is based on only a few available paleo-reconstructions of the type we used. Thus, the 20th century portion of our paleotemperature stack is not statistically robust, cannot be considered representative of global temperature changes, and therefore is not the basis of any of our conclusions.

Got that?

In case you missed it, I repeat:

. . . the 20th century portion of our paleotemperature stack is not statistically robust, cannot be considered representative of global temperature changes . . .

What that means is that this paper actually has nothing to do with a “hockey stick” as it does not have the ability to reproduce 20th century temperatures in a manner that is “statistically robust.” The new “hockey stick” is no such thing as Marcott et al. has no blade. (To be absolutely clear, I am not making a point about temperatures of the 20th century, but what can be concluded from the paper about temperatures of the 20th century.)

thanks to andrew for the links..

more lies..and the key point here is that they announce these claims with all this grandeur..but when its shown to be total theory,conjecture and not representative..there is no media follow up to deny it..evidence of the scam continuing with willing participants in the media who are are either to scared to be truthful or just totally ignorant..
