S. Fred Singer, a distinguished physicist and coauthor of Climate Change Reconsidered II: Physical Science, writes a devastating critique of the United Nations' Intergovernmental Panel on Climate Change (IPCC)'s Summary for Policymakers of its Fifth Assessment Report. According to Singer, “This new SPM reveals that the IPCC has retreated from about a dozen alarmist claims promulgated in its previous reports or by scientists who are prominently associated with the IPCC. Their SPM also contains more than a dozen misleading or untrue statements, plus about another dozen statements that mislead readers or misrepresent important aspects of the science.”

This essay is based on a Policy Brief published by NIPCC in October 2013, titled “Scientific Critique of IPCC’s 2013 ‘Summary for Policymakers,’ by Craig D. Idso, Robert M. Carter, S. Fred Singer, and Willie Soon.” It can be accessed at

Dr. S. Fred Singer was among the first and is still the most prominent scientist in the world speaking out against global warming alarmism.
