Several prominent scientists have pointed out the [[politicized science]] of the UN's assessment methods. The scientific reports are submitted to a panel of representatives appointed by each country in the IPCC. Several scientists have complained about their work being misrepresented by the U.N.
One scientist, Michael Mann, was investigated by the U.S. Senate for a [[scientific fraud]] uncovered by two persistent statistics experts (see [[Hockey stick graph]]).
*Mr. Mann testified before the Senate committee that his research is the "mainstream view" because it is featured in a chapter of the U.N. Nations Intergovernmental Panel on Climate Change (IPCC) report, of which Mr. Mann was a lead author. Mr. Soon and Ms. Baliunas challenged Mr. Mann's claim by reviewing the large body of literature that shows his claims to be unsubstantiated and his research to be fatally flawed. In truth, Mr. Mann's work is the scientific outlier — the one study that does not fit with the wealth of scientific evidence. <ref>http://washingtontimes.com/commentary/20030825-090130-5881r.htm</ref>
