Sebastian Luening, paleogeologist: Michel de Rougemont chemical engineer: Without questioning the observed global warming or the emissions to the atmosphere of infrared-absorbing gases, three central issues remain without properly quantified responses, without which no other climate policy than that of a gradual adaptation can be justified: the sensitivity of the climate to human contributions, the disadvantages and the benefits for mankind resulting from a generally warmer climate, and the foreseeable evolution of the climate in consequence of unpredictable changes in human activity.
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.
