Rubert Darwall, strategy consultant and policy analyst. He read economics and history at Cambridge University, Judith Curry, former Professor and Chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology: How dependable is climate science? Global warming mitigation policies depend on the credibility and integrity of climate science. In turn, that depends on a deterministic model of the climate system in which it is possible to quantify the role of carbon dioxide (CO2) with a high degree of confidence. This essay explores the contrast between scientists’ expressions of public confidence and private admissions of uncertainty on critical aspects of the science that undergirds the consensus.
Vaclav Havel, , first Prime Minister (1993–1998) and second President of the Czech Republic (2003–2013). The issue of climate alarmism, of man-made and human society endangering global warming has become one of my main topics as well as worries. I strongly disagree with the global warming doctrine which is an arrogant, human freedom and prosperity of mankind endangering set of beliefs, an ideology, if not a religion. It lives independently of the science of climatology. Its disputes are not about temperature, they are part of the “conflict of ideologies”.
Tim Ball, Environmental Consultant, Tom Harris, Executive Director of International Climate Science Coalition, Paul Driessen, Senior Policy Advisor, Committee For A Constructive Tomorrow: The plot to deceive the world about human-caused global warming gathered momentum right after the World Meteorological Organization and United Nations Environment Program (UNEP) created the United Nations Intergovernmental Panel on Climate Change (IPCC) in 1988. “Dr. James E. Hansen of the National Aeronautics and Space Administration told a Congressional committee that it was 99 percent certain that the warming trend was not a natural variation.” More than any other event, that single hearing before the Energy and Natural Resources Committee publicly initiated the climate scare, the biggest deception in history. It created an unholy alliance which was bolstered by the U.N. and the popular press – leading to the hoax being accepted in governments, industry boardrooms, schools and churches all across the world.
Howard Cork Hayden, Emeritus Physics Professor, University of Connecticut: This is a closing argument by Professor Hayden. The debate took place at Colorado State University - Pueblo on December 2, 2017. The other person in the debate was Professor Scott Denning of CSU - Fort Collins. Use search box with Denning to find his presentation.
Howard Hayden, December 19, 2017: What, then, is the basis for saying CO2 causes warming? More CO2 causes more absorption of IR in the far wings of the spectrum, and pretty high in the atmosphere. That absorbed energy rapidly adds heat to the local air, and is generally not radiated back to the surface. The actual atmospheric processes cannot be ignored, and they are not simple as Scott Denning avers.
