Clinton, Hillary (D) - Not Clearly Pro or Con Hillary Clinton, U.S. Senator (D-NY), stated in a YouTube.com video of a Town Hall Meeting in Des Moines, IA titled "Hillary Clinton Answers a Global Warming Question in Iowa" (accessed Mar. 18, 2008): "...[T]he President [George W. Bush] and Vice President [Dick Cheney] refuse to admit that there were any human contributions to global climate change. There are climatic changes that are so-called natural, but we have so changed the atmosphere that it has a ripple effect...Yes, there are natural reasons why the climate may get warmer but we put so much CO2 into the atmosphere that that changes the natural forces..."

Gravel, Mike (Lib) - Not Clearly Pro or Con

Mike Gravel, former U.S. Senator (D-AK), in an article titled "How Mike Stands on the Issues" on his official candidate website (accessed Mar. 18, 2008), stated: "Senator Gravel believes that global climate change is a matter of national security and survivability of the planet.

		Keyes, Alan (Ind) - Con Alan Keyes, former Assistant U.S. Secretary of State, stated in a Sep. 30, 2000 article titled "Debunking the Gashouse Gang," posted on the Renew America website: "Just how likely is it that increasing levels of carbon dioxide resulting from human use of fossil fuels will cause a significant increase in global temperature — and that such an increase will be seriously harmful to human society?... A survey of what reputable scientists are actually saying on the question, however, suggests that it is quite likely that no one on earth knows just 'how likely' these bad results are. In fact, I think it is quite unreasonable for anyone to be confident that we face a human-induced global warming that will, on balance, be harmful rather than beneficial for humanity or the environment, much less that such a warming would be catastrophic." Sep. 30, 2000 Alan Keyes

McCain, John (R) - Not Clearly Pro or Con John McCain, U.S. Senator (R-AZ), stated in a Sep. 27, 2007 National Review article titled "America's Strategic Vulnerability: Vital Energy Questions": "I also believe that strengthening our energy security goes hand-in-hand with addressing global climate change, which I believe is real with human activity contributing to the buildup of greenhouse gases in the atmosphere." Sep. 27, 2007 John McCain

McKinney, Cynthia (Grn) - Not Clearly Pro or Con Cynthia McKinney, former U.S. House Representative (D-GA), stated in her May 1, 2007 Green Party Presidential Candidate Questionnaire: "The situation is now quite clear. The United States can no longer hide its truculence under the mask of weather fluctuations or unclear science, islands are disappearing, indigenous ways of life are threatened, indeed the world as we know it is at risk if the United States continues to do nothing." May 1, 2007 Cynthia McKinney

Nader, Ralph (Ind) - Not Clearly Pro or Con Ralph Nader, attorney, author, and political activist, was quoted in a video titled "Ralph Nader Proposing a Green Party to Take on Global Warming -- The 'Spoiler' Candidate Speaks During the 2000 Election," posted on vimeo.com (accessed Apr. 9, 2008): "The very things we should do for the family pocketbook, more fuel-efficient cars, more solar energy, more fuel-efficient appliances, lighting, air conditioning systems, will also reduce the contribution to global warming." Apr. 9, 2008 Ralph Nader

Obama, Barack (D) - Pro Barack Obama, U.S. Senator (D-IL), stated in an article titled "Barack Obama's Plan to Make America a Global Energy Leader" on his official candidate website (accessed Mar. 13, 2008): "Global warming is real, is happening now and is the result of human activities. The number of Category 4 and 5 hurricanes has almost doubled in the last 30 years. Glaciers are melting faster; the polar ice caps are shrinking; trees are blooming earlier; oceans are becoming more acidic, threatening marine life; people are dying in heat waves; species are migrating, and eventually many will become extinct." Mar. 13, 2008 Barack Obama

Paul, Ron (R) - Not Clearly Pro or Con

Ron Paul, U.S. Representative (R-TX), stated in an Oct. 16, 2007 interview "Paul on the Record," with environmental website Grist.org: "I think some of it [global warming] is related to human activities, but I don't think there's a conclusion yet. There's a lot of evidence on both sides of that argument. If you study the history, we've had a lot of climate changes. We've had hot spells and cold spells. They come and go. If there are weather changes, we're not going to be very good at regulating the weather." Oct. 16, 2007 Ron Paul

Mar. 11, 2008 Daniel Imperato Top      Kubby, Steve (Lib) - Not Clearly Pro or Con    Steve Kubby, founder of the American Medical Marijuana Association, stated in a Mar. 12, 2008 email to ProCon.org: "Most scientists believe that humans are responsible for some portion of the factors driving global climate change. Many scientists disagree on whether or not that portion is 'substantial.' As it happens, though, the policies we need to follow for other reasons -- reasons like reducing our dependence on finite distant energy sources in hostile lands, and reducing pollution which threatens human health -- are the same policies we would need to follow to reduce whatever our actual climate impact is. We need to stop subsidizing the petroleum industry and hiding the true cost of its products. We need to let alternative energy sources compete on a playing field that isn't controlled, through government, by Big Oil."

I do, however, welcome the debate as it points out that we are severely lacking any long-term energy planning as a country and on a worldwide basis."
