The data set of proxies of past climate used in Mann, Bradley and Hughes (1998, “MBH98” hereafter) for the estimation of temperatures from 1400 to 1980 contains collation errors, unjustifiable truncation or extrapolation of source data, obsolete data, geographical location errors, incorrect calculation of principal components and other quality control defects. We detail these errors and defects. We then apply MBH98 methodology to the construction of a Northern Hemisphere average temperature…

Robustness of the Mann, Bradley, Hughes reconstruction of Northern Hemisphere surface temperatures: Examination of criticisms based on the nature and processing of proxy climate evidence
The Mann et al. (1998) Northern Hemisphere annual temperature reconstruction over 1400–1980 is examined in light of recent criticisms concerning the nature and processing of included climate proxy

Abstract Results are presented from a set of experiments designed to investigate factors that may influence proxy-based reconstructions of large-scale temperature patterns in past centuries. The
Uncertainties in Assessing Global Warming during the 20th Century: Disagreement between Key Data Sources
We have reanalyzed the available data on the terrestrial temperature in the Northern Hemisphere over the past 1000 years using both direct observations and various proxy records. It is shown that the

McIntyre and McKitrick (1) (henceforth MM04) are incorrect with respect to each major point they raise, including those concerning the main data sets we used and the principal components algorithm
Discussion of: A statistical analysis of multiple temperature proxies: Are reconstructions of surface temperatures over the last 1000 years reliable?
TLDR
Despite a good effort to capture the various points of contention in the reconstruction arena, McShane and Wyner (2011) provide an incomplete, and at times inadequate, review of the existing literature considering reconstruction of Northern Hemisphere surface temperatures over the past millennium.

TLDR
The centennial variability of the NH temperature is underestimated by the regression-based methods applied here, suggesting that past variations may have been at least a factor of 2 larger than indicated by empirical reconstructions.
