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 data. A systematic sequence of analyses is presented that examine issues concerning the proxy evidence, utilizing both indirect analyses via exclusion of proxies and processing steps subject to criticism, and direct analyses of principal component (PC) processing methods in question. Altogether new… Expand

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. Expand
The ‘hockey stick’ and the 1990s: a statistical perspective on reconstructing hemispheric temperatures
Abstract The short instrumental record of about 100–150 yr forces us to use proxy indicators to study climate over long timescales. The climate information in these indirect data is embedded inExpand
The importance of the geophysical context in statistical evaluations of climate reconstruction procedures
TLDR
It is shown that there is now a need to move beyond hemispheric average temperatures and to focus instead on resolving climate variability at the socially more relevant regional scale. Expand
Proxy-based reconstructions of hemispheric and global surface temperature variations over the past two millennia
TLDR
The results extend previous conclusions that recent Northern Hemisphere surface temperature increases are likely anomalous in a long-term context to at least the past 1,700 years, but with additional strong caveats. Expand
On the verification of climate reconstructions
Abstract. The skill of proxy-based reconstructions of Northern hemisphere temperature is reassessed. Using an almost complete set of proxy and instrumental data of the past 130 years aExpand
Climate of the Past On the verification of climate reconstructions
The skill of proxy-based reconstructions of Northern hemisphere temperature is reassessed. Using an almost complete set of proxy and instrumental data of the past 130 years a multi-crossvalidation isExpand
Analysis of the Moberg et al. (2005) hemispheric temperature reconstruction
The Moberg et al. (Nature 433(7026):613–617, 2005. doi:10.1038/nature03265; M05) reconstruction of northern hemisphere temperature variations from proxy data has been criticised; the M05 method mayExpand
A statistical analysis of multiple temperature proxies: Are reconstructions of surface temperatures over the last 1000 years reliable?
Predicting historic temperatures based on tree rings, ice cores, and other natural proxies is a difficult endeavor. The relationship between proxies and temperature is weak and the number of proxiesExpand
Assessment of three temperature reconstruction methods in the virtual reality of a climate simulation
The performance of statistical climate reconstruction methods in the pre-instrumental period is uncertain, as they are calibrated in a short instrumental period but applied to much longerExpand
Pseudo-proxy evaluation of Climate Field Reconstruction methods of North Atlantic climate based on an annually resolved marine proxy network
Abstract. Two statistical methods are tested to reconstruct the interannual variations in past sea surface temperatures (SSTs) of the North Atlantic (NA) Ocean over the past millennium based onExpand
