"I'm sure the majority (but not all) of my IPCC colleagues cringe when I say this, but I see neither the developing catastrophe nor the smoking gun proving that human activity is to blame for most of the warming we see." - John R. Christy
Patrick J. Michaels, A.B. Biological Sciences, S.M. Biology, Ph.D. Ecological Climatology, Virginia State Climatologist (1980-2007), Associate Professor of Environmental Sciences, University of Virginia (1986-1995), President, American Association of State Climatologists (1987-1988), Research Professor of Environmental Sciences, University of Virginia (1996-Present), IPCC Contributing Author and Reviewer
"A number of studies point to sources other than greenhouse gases as explanations for the modest warming trend of the late 20th century." - Patrick J. Michaels

Applied Mathematics (Harvard), Ph.D. Applied Mathematics (Harvard), Research Scientist, National Center for Atmospheric Research (1966-1967), Associate Professor and Professor of Meteorology, University of Chicago (1968-1972), Professor of Dynamic Meteorology, Harvard University (1972-1983), Director, Center for Earth and Planetary Physics, Harvard University (1980-1983), Alfred P. Sloan Professor of Meteorology, Department of Earth, Atmospheric and Planetary Sciences, Massachusetts Institute of Technology (MIT) (1983-Present), Fellow of the American Meteorological Society, Fellow of the American Geophysical Union, IPCC Lead Author (2001)
"Given that the evidence strongly implies that anthropogenic warming has been greatly exaggerated, the basis for alarm due to such warming is similarly diminished." - Richard S. Lindzen
Roy W. Spencer, B.S. Atmospheric Sciences, M.S. Meteorology, Ph.D. Meteorology, Research Scientist, University of Wisconsin (1982-1984), Senior Scientist for Climate Studies, NASA (1984-2001), NASA Exceptional Scientific Achievement Medal (1991), American Meteorological Societys Special Award (1996), Principal Research Scientist, University of Alabama in Huntsville (2001-Present)
"As a climate researcher, I am increasingly convinced that most of our recent global warming has been natural, not manmade." - Roy W. Spencer
S. Fred Singer, A.M. Physics (Princeton), Ph.D. Physics (Princeton), First Director, National Weather Satellite Center (1962-1964), First Dean of the School of Environmental and Planetary Sciences, University of Miami (1964-1967), Deputy Assistant Secretary (Water Quality and Research), U.S. Department of the Interior (1967-1970), Deputy Assistant Administrator, U.S. Environmental Protection Agency (1970-1971), Professor of Environmental Science, University of Virginia (1971-1994), Research Professor, Institute for Humane Studies at George Mason University (1994-2000)
"We see no evidence in the climate record that the increase in CO2, which is real, has any appreciable effect on the global temperature." - S. Fred Singer
Sherwood B. Idso, B.S. Physics, M.S. Soil Science, Ph.D. Soil Science, Research Scientist, U.S.D.A.

"I find no compelling reason to believe that the earth will necessarily experience any global warming as a consequence of the ongoing rise in the atmosphere's carbon dioxide concentration." - Sherwood B. Idso
