Professor and Director, Atmospheric Science Department, University of Alabama at Huntsville (UAH website)<br /> Alabama State Climatologist. Lead Author, 2001 IPCC TAR. <br />

While he now acknowledges that global warming is real and the human contribution is significant, Christy has been a long-time skeptic who previously argued that satellite climate data do not show a trend toward global warming, and even show cooling in some areas. His findings have been refuted by multiple independent studies (also see "Errors Cited in Assessing Climate Data", New York Times, August 12, 2005). Christy now asserts that global warming will have beneficial effects on the planet and that increased CO2 emissions from human activities are a net positive.<br />

Christy was a contributing writer to "Global Warming and Other Eco-Myths," published by the Competitive Enterprise Institute in 2002. He spoke at a June 1998 briefing for congressional staff and media, which was sponsored by the Cooler Heads Coalition.<br />

Key Quotes

"It is our great fortune - because we produce so much of it - that carbon dioxide is not a pollutant. In simple terms, carbon dioxide is plant food. The green world we see around us would disappear if not for atmospheric carbon dioxide."<br />Source: Transcript, John Christy's testimony before Senate Committee on Commerce, Science, and Transportation, 5/17/00. <br />

"The factors that influence climate are too numerous to document, much less understand from our present level of ignorance. ...The alarmist media reports...become the source of downstream hysteria promoted by those with extreme environmental agendas. Such pronouncements by ideological environmentalists that the globe's weather is worsening are acutally false."<br />Source: "Global Warming and Other Eco-Myths: How the Environmental Movement Uses False Science to Scare Us to Death".<br />

"I don't see danger. I see, in some cases, adaptation, and in others something like restrained glee, at the thought of longer growing seasons, warmer winters, and a more fertile atmosphere."<br /> Source: Cato Institute Conference - Global Warming: The State of the Debate (December 12, 2003)<br />

"This notion of the greening of the planet [from human-caused CO2 emissions] ... generally is a positive benefit." <br />Source: Associated Press (October 20, 2006)<br />

"It disturbs me when I hear that energy and its byproducts such as CO2 are being demonized when in fact they represent the greatest achievement of our society. Where there is no energy, life is brutal and short. When you think about that extra CO2 in the air, think also about an 8-fold increase in the experience of human life." <br /> Source: Transcript (pdf), John Christy's testimony before the House Subcommittee on Energy and Air Quality.

"I've often heard it said that there is a consensus of thousands of scientists on the global warming issue, that humans are causing a catastrophic change to the climate system. Well, I am one scientist - and there are many - that simply think that is not true." <br />Source: The Great Global Warming Swindle (Documentary, 2007)<br />

'"Half of the snow was gone when Hemingway wrote 'The Snows of Kilimanjaro.' That tells you right there that the cause of that was not human effects on the climate. There is no upward trend in the temperature for that region. The reason the snows are going away is not because of temperature changes, but probably because of a lowering of the cloud amount and less precipitation." <br /> Source: Glenn Beck special "Exposed: The Climate of Fear" May 2, 2007<br />

"The Nobel committee praises Mr. Gore and the IPCC for alerting us to a potential [climate] catastrophe and for spurring us to a carbonless economy... I see neither the developing catastrophe nor the smoking gun proving that human activity is to blame for most of the activity we see."<br /> Source: Op-Ed in the Wall Street Journal, "My Nobel Moment", Nov. 1, 2007<br />

"Will increases in CO2 affect the climate significantly? Are significant changes occurring now? Climate models suggest the answer is yes, real data suggests otherwise." <br />Source: Testimony, House Committee on Natural Resources<br />
