«I think one should take our social network analysis with a grain of salt to understand that this is an unusual configuration of people with a highly central person involved in this. It is no surprise to any working scientist that there are groups of statisticians, groups of mathematicians, groups of paleoclimate scientists, groups of physicists that work together closely and that there are competing social networks.» Edward Wegman i kongresshøring i juli 2006, se stenografisk referat.

Anders Moberg, Dmitry M. Sonechkin, Karin Holmgren, Nina M. Datsenko, Wibjörn Karlén og Stein-Erik Lauritzen: «Highly variable Northern Hemisphere temperatures reconstructed from low- and high-resolution proxy data», i Nature 433 (10. februar 2005). Sitat: «We find no evidence for any earlier periods in the last two millennia with warmer conditions than the post-1990 period—in agreement with previous similar studies. The main implication of our study, however, is that natural multicentennial climate variability may be larger than commonly thought, and that much of this variability could result from a response to natural changes in radiative forcings. This does not imply that the global warming in the last few decades has been caused by natural forcing factors alone, as model experiments that use natural-only forcings fail to reproduce this warming. Nevertheless, our findings underscore a need to improve scenarios for future climate change by also including forced natural variability—which could either amplify or attenuate anthropogenic climate change significantly.» (Lauritzen var ved en feil utelatt som medforfatter i den publiserte artikkelen, noe som blei korrigert seinere.)

«The editor-in-chief of Climate Research, Hans Von Storch, resigned after the publisher of Climate Research refused to print a retraction, as did four other editors. In his resignation letter, Von Storch wrote: "The review process had utterly failed; important questions have not been asked ... the methodological basis for such a conclusion (that the 20th century is probably not the warmest nor a uniquely extreme climate period of the last millennium) was simply not given."» Fra Stephen Cauchi: «Global warming: a load of hot air?», i The Age 17. januar 2004.
