A Partial List of Global Warming Skeptics

A Partial List of Global Warming Scientist Skeptics

• Chris de Freitas, Associate Professor, School of Geography, Geology and Environmental Science, University of Auckland, who believes the Earth is warming but the cause is unknown.

Scientists in this next section accept the observations of rising temperatures, but conclude it is too early to ascribe any cause to these changes, man-made or natural.

• Claude Allègre, French geophysicist, Institute of Geophysics (Paris
• Robert C. Balling, Jr., director of the Office of Climatology and an associate professor of geography at Arizona State University[7])
• David Deming, geology professor at the University of Oklahoma Committee on Environment and Public Works, December 6, 2006 [8])
• Richard Lindzen, MIT meteorology professor and member of the National Academy of SciencesRoy Spencer, principal research scientist, University of Alabama in Huntsville
• (George C. Marshall Institute Washington Roundtable on Science and Public Policy, April 17, 2006 [11])

Scientists in this section accept the observations of rising temperature, but conclude that natural causes are likely more to blame than human activities.

• David Legates, associate professor of geography and director of the Center for Climatic Research, University of Delaware
• Marcel Leroux, former Professor of Climatology, Université Jean Moulin
• Tim Patterson [26], paleoclimatologist and Professor of Geology at Carleton University in CanadaFrederick Seitz, retired, former solid-state physicist, former president of the National Academy of Sciences, who has stated that, "So we see that the scientific facts indicate that all the temperature changes observed in the last 100 years were largely natural changes and were not caused by carbon dioxide produced in human activities.", Environment News, 2001 [28]
• Nir Shaviv, astrophysicist at the Hebrew University of Jerusalem

• Willie Soon, Harvard-Smithsonian Center for Astrophysics:
• Henrik Svensmark, Danish National Space Center
• Jan Veizer, environmental geochemist, Professor Emeritus from University of Ottawa:
This section contains scientists who accept that global warming will occur, but advocate the position that it will be of little impact or a net positive for human society.
• Sherwood Idso, former research physicist, USDA Water Conservation Laboratory, and adjunct professor, Arizona State University, who has stated, "[W]arming has been shown to positively impact human health, while atmospheric CO2 enrichment has been shown to enhance the health-promoting properties of the food we eat, as well as stimulate the production of more of it. ... [W]e have nothing to fear from increasing concentrations of atmospheric CO2 and global warming.", Enhanced or Impaired? Human Health in a CO2-Enriched Warmer World, co2science.org, Nov, 2003, p. 30 ([36]).
