Prominent members of the climate research community did not respond to the article by engaging use in a dispute over the facts.

==Distortion of the facts==
The pro-Kyoto side of the equation has famously asserted that temperatures in 1998-2007 are the highest in 1,000 years. However, peer-reviewed research published in scientific journals contradicts this claim.
In 2003, the "[[hockey stick graph]]" of [[Michael Mann]] was examined by McIntyre and McKitrick in ''Energy & Enviornment''. They found that:
: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.
