Just over a month before the United Nations convenes on September 23 in New York City to discuss climate change and activists gather for a week of action, the Obama White House Council on Environmental Quality (CEQ) argued it does not have to offer guidance to federal agencies it coordinates with to consider climate change impacts...read more

J. Scott Armstrong Ph.D is a marketing professor at the Wharton School of Business at the University of Pennsylvania. According to his website, Armstrong's work focuses mainly on forecasting methods, strategic planning, survey research, and research methods.
Armstrong was the editor of Principles of Forecasting and the author of Long-Range Forecasting and Principles of Forecasting. He is also the co-founder of forecastingprinciples.com.
Stance on Climate Change
When Armstrong extended “The Climate Challenge” to Al Gore in June, 2007, he based his forecasts on “the naive (no-change) model; that is, the forecasts would be the same as the most recent year prior to the forecasts.”
“We published a peer-reviewed paper showing that the forecasting procedures used by the U.N.'s Intergovernmental Panel on Climate Change violated 72 of 89 relevant principles (e.g., 'provide full disclosure of methods'). The IPCC has been unable to explain why it violated such principles. In response, we developed a model that follows the principles. Because the climate is complex and poorly understood, our model predicts that global average temperatures will not change.”

Other climate change skeptics who signed include Claude Allègre, Jan Breslow, William Happer, William Kininmonth, Richard Lindzen, James McGrath, Rodney Nichols, Burt Rutan, Harrison H. Schmitt, Nir Shaviv, Edward David, Michael Kelly, Henk Tennekes, and Antonino Zichichi.
Media transparency found that the Op-Ed had misrepresented the position of Yale economist William Nordhaus. SkepticalScience also did a comprehensive examination of the signatories and found that few of them had published anything in peer-reviewed journal on the subject of climate change. , 
Armstrong was a speaker at the Heartland Institute's 2010 International Conference on Climate Change. 
His speech was titled “Global Warming: A Scientific Forecasting Controversy
or a Political Movement?”

Armstrong's signature is displayed alongside a full-page ad funded by the CATO institute that appeared in numerous newspapers including the Washington Post, the New York Times and the Chicago Tribune in 2009.
The ad criticizes President Obama's declaration that “few challenges facing America and the world are more urgent than combating climate change,” stating that “with all due respect Mr. President, that is not true.” It goes on to claim that “there has been no net global warming for over a decade,” and that the dangers of climate change are “grossly overstated.” 
Armstrong presented his research paper (co-authored by fellow skeptics Willie Soon and Kesten Green) on forecasting polar bear populations at the Heartland Institute's 2009 International Conference on Climate Change.
The paper, titled “Polar Bear Population Forecasts: A Public-Policy Forecasting Audit,” was published in Marketing Papers in 2008 and criticized projections of declining polar bear populations.

In June, 2007, Armstrong extended a “Global Warming Challenge” to Al Gore. Although Al Gore declined the bet, Armstrong continued to track the hypothetical outcome on his website theclimatebet.com; he maintains that average temperatures will remain constant or drop rather than rise. 
Armstrong continues to use theclimatebet.com as a forum to post his research.
- Kesten Green, Willie Soon — Co-authored studies on climate change, and testified before congress on the subject of climate change. Green also serves as “advisor” to Armstrong's website, theclimatebet.com.
Scott Armstrong, Willie Soon, and Kesten Green released an “unpublished working paper” arguing that the current forecast data on polar bear populations is inadequate for making a decision as to whether polar bears should be listed as a threatened species under the US Endangered Species Act.
While the polar bear paper is not published in a peer-reviewed scientific journal, it has appeared on websites such as the Science and Public Policy Institute website, Spiked Online, and various blogs.
His report was critiqued by the science writers at Realclimate.org who accuse Armstrong of having read “none of the primary literature,” only one chapter of the IPCC report and only “an un-peer reviewed hatchet job on the Stern Report” (a 2006 report on the economic impact of global warming completed by the British government). 
He also published a more recent paper: with Kesten Green in 2011 titled “Effects of the global warming alarm: A forecasting project using the structured analogies method” (PDF). Although this paper does not appear to be published in a peer-reviewed journal, Green and Armstrong do claim to “seek peer review from others, especially with evidence that would challenge our findings or conclusions.”
