M.A. Kaufman, in his Aug. 22 letter, hints that there are some climate scientists out there who deny anthropogenic climate change. About six months ago I challenged all Spokesman readers to come up with a single article in a peer-reviewed science magazine within the last five years in which the author denied human-caused global warming.

What I received was a rebuttal from Sue Lani Madsen about a peer-review article by Polisar that supposedly refuted man-caused global warming, but which in reality confirmed anthropological climate change. (Polisar uses “anthropogenic.”)

I received several other articles: one written by a biochemist, Dr. Robinson, who started the Oregon Institute of Science, which has eight faculty, two of whom are deceased, two of whom are his children and none of whom was trained as a climate specialist.

Other articles included one by a Russian physicist, one from a weatherman who was an ex-disc jockey with no science background, and several politicians, but not one from a peer-reviewed science magazine or by a climate expert.

So if Mr. Kaufman has a peer-reviewed article by a climate expert denying anthropogenic global warming I would love to read it.
