Apparently, the "science is settled", or maybe not:
“I think that climatic changes have a natural causes according many geological data…I am very glad to sign the U.S. Senate’s report of scientists against the theory of man-made global warming.” - Geology Professor Uberto Crescenti of the University G.d'Annunzio in Italy is the past president of the Society of Italian Geologists.
“I am appalled at the state of discord in the field of climate science…There is no observational evidence that the addition of anthropogenic greenhouse gas emissions have caused any temperature perturbations in the atmosphere.” - Award-winning atmospheric scientist Dr. George T. Wolff, former member of the EPA’s Science Advisory Board, served on a committee of the National Oceanic and Atmospheric Administration (NOAA) and authored more than 90 peer-reviewed studies.
“The sky is not burning, and to claim that it is amounts to journalistic malpractice…the press only promotes the global warming alarmists and ignores or minimizes those of us who are skeptical.” - Chemist Dr. Mark L. Campbell, a professor of chemistry at the U.S. Naval Academy in Annapolis, MD, who has published numerous studies in the Journal of the American Chemical Society on topics such as methane.
“Once again we have misleading climate change pronouncements being based on data errors, data errors detected by non-UN, non-IPCC, non-peer-reviewed external observers…This is exactly what happens when you base your arguments on ‘consensus science’ and not scientific fact.” - Professor Dr. Doug L. Hoffman, a mathematician, computer programmer, and engineer, who worked on environmental models and conducted research in molecular dynamics simulations. Hoffman co-authored the 2009 book, The Resilient Earth, described as “bringing a dose of skeptical reality to climate science and the global warming debate.”
“The questions are scientific, but the UN answers are political. The global warming debate is hardly about science.” - Computer Modeler and Engineer Allen Simmons, who worked 12 years with NASA's top climate scientists and wrote computer systems software for the world's first weather satellites and aided in the development of computer systems for polar orbiting satellites. Simmons co-authored the new skeptical book The Resilient Earth.
Belief in climate models compared to “ancient astrology”… "I believe the anthropogenic (man-made) effect for climate change is still only one of the hypotheses to explain the variability of climate.” - Award-winning Japanese Physicist Dr. Kanya Kusano, program director of the Japan Agency for Marine-Earth Science and Technology who’s research “focuses on the immaturity of simulation work cited in support of the theory of anthropogenic climate change.” compared climate models to “ancient astrology.”
“The recent ‘panic’ to control GHG (greenhouse gas) emissions and billions of dollars being dedicated for the task has me deeply concerned that US, and other countries are spending precious global funds to stop global warming, when it is primarily being driven by natural forcing mechanisms.” - Climatologist and Paloeclimate researcher Dr. Diane Douglas, who has authored or edited over 200 technical reports, specialized in the reconstruction of a variety of proxy data and has worked for the Department of Energy and conducted research for the Arizona State Office of Climatology to investigate the Little Ice Age.
“Temperature measurements show that the [climate model-predicted mid-troposphere] hot zone is non-existent. This is more than sufficient to invalidate global climate models and projections made with them!”- UN IPCC Scientist Dr. Steven M. Japar, a PhD atmospheric chemist who was part of Intergovernmental Panel on Climate Change’s (IPCC) Second (1995) and Third (2001) Assessment Reports, and has authored 83 peer-reviewed publications and in the areas of climate change, atmospheric chemistry, air pollutions and vehicle emissions.
“The cause of these global changes is fundamentally due to the Sun and its effect on the Earth as it moves about in its orbit. Not from man-made activities.” - Retired Award Winning NASA Atmospheric Scientist Dr. William W. Vaughan, recipient of the NASA Exceptional Service Medal, a former Division Chief of NASA’s Marshall Space Flight Center and author more than 100 refereed journal articles, monographs, and papers.
“Unfortunately, Climate Science has become Political Science…It is tragic that some perhaps well-meaning but politically motivated scientists who should know better have whipped up a global frenzy about a phenomena which is statistically questionable at best.” - Award-Winning Princeton University Physicist Dr. Robert H. Austin, who has published 170 scientific papers, was elected a member of the U.S. National Academy of Sciences and is the current Chair of the U.S. Liaison Committee of the International Union of Pure and Applied Physics.
“Based on the laws of physics, the effect on temperature of man’s contribution to atmospheric CO2 levels is minuscule and indiscernible from the natural variability caused in large part by changes in solar energy output.” - Atmospheric Scientist Robert L. Scotto, who has more than 30 years air quality consulting experience, served as a manager for an EPA Superfund contract and is co-founder of Minnich and Scotto, Inc., a full-service air quality consulting firm. He also is a past member of the American Meteorological Society (AMS). Scotto, a meteorologist who has authored or co-authored numerous technical publications and reports.
“Whether the ice caps melt, or expand --- whatever happens --- the AGW (anthropogenic global warming) theorists claim it confirms their theory. A perfect example of a pseudo-science like astrology.” - Mathematical Physicist Dr. Frank Tipler, professor at Tulane University has authored 58 peer-reviewed publications and five books.
“My dear colleague [NASA’s James] Hansen, I believe, has finally gone off the deep end... The global warming ‘time bomb,’ ‘disastrous climate changes that spiral dynamically out of humanity's control.’ These are the words of an apocalyptic prophet, not a rational scientist.” - Chemist Dr. Nicholas Drapela of the faculty of Oregon State University Chemistry Department
“There is no credible evidence of the current exceptional global warming trumpeted by the IPCC…The IPCC is no longer behaving as an investigative scientific organization or pretending to be one…Their leaders betrayed the trust of the world community.” - Chemist Dr. Grant Miles, author of numerous scientific publications who was elected to a Fellowship of the Royal Institute of Chemistry, was a member of UK Atomic Energy Authority Chemical Separation Plant Committee.
