People send me stuff. Robert Sheaffer sent part of a blog post titled:
The “hockey stick” slaps back by Donald Prothero
After reading it, this is what I mailed back:
Oh please, Marcott et al has been fully debunked for recent temperatures. Even Marcott himself admits the uptick is not robust on RealClimate.
Marcott et al have posted their long-promised FAQ at realclimate here. Without providing any links to or citation of Climate Audit, they now concede:
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.
