In 1989, in an article in Forbes, Bailey wrote a "...sneering attack..." on Jay Forrester, the father of system dynamics. In the article he described the book, The Limits to Growth as "as wrong-headed as it is possible to be." Bailey said that, "Limits to Growth predicted that at 1972 rates of growth the world would run out of gold by 1981, mercury by 1985, tin by 1987, zinc by 1990, petroleum by 1992, copper, lead and natural gas by 1993." According to physical chemist and energy expert, Ugo Bardi, "...Bailey's accusations are just plain wrong." In 1993 Bailey repeated his accusations in his book, Ecoscam. In it, he claimed that none of the projections of the 1972 LTG study turned out to be correct. In his 1993 book, Ecoscam, Bailey wrote, "Despite a great deal of continuing scientific uncertainty, it appears that CFCs do contribute to the creation of the Antarctic ozone hole and perhaps a tiny amount of global ozone depletion.... t makes sense to phase out the use of CFCs." When Science reported in July 2016 that the ozone layer was restoring itself after CFCs were banned, Bailey wrote, "Since atmospheric pollution presents significant barriers to assigning property rights, I concluded that the international treaty banning CFCs was the appropriate response." The position taken in his 1995 book The True State of the Planet has been described as "growth forever" or "Promethean" arguing for unrestrained exploitation based on assumptions of unending nature, value derived exclusively from man's changes to material, and exceptional human resourcefulness. His follow-up book Earth Report 2000 was recognized for being among the works of established authors "who have argued that past and present widely accepted visions of environmental deterioration and disaster... have little or no basis in fact." Citing these two books, Holt, Pressman and Spash describe the CEI as believing, "technology will solve all environmental problems and that present environmental dilemmas are simply a necessary outcome of much needed economic growth." Bailey has described himself as a "libertarian transhumanist." He explains this in his book Liberation Biology. In 2005, Bailey said that new data convinced him that the earth is definitely warming and that the likely cause is human activity. He has endorsed a carbon tax as one possible solution. He has stated in the article "Global Warming — Not Worse Than We Thought, But Bad Enough":
Details like sea level rise will continue to be debated by researchers, but if the debate over whether or not humanity is contributing to global warming wasn't over before, it is now ... as the new IPCC Summary makes clear, climate change Pollyannaism is no longer looking very tenable.
Bailey is critical of Al Gore and his film about global warming, writing, "On balance Gore gets it more right than wrong on the science, but he undercuts his message by becoming the opposite of a global warming denier. He's a global warming exaggerator." Bailey voted for George W. Bush in both 2000 and 2004, a fact which he later wrote made him "disheartened and ashamed." In 2008, he voted for Barack Obama because he felt that "he Republicans must be punished and punished hard."
