Professor Scott Armstrong of the Wharton School of Business at the Univ. of Pennsyvania, also associated with the Heartland Institute, is internationally known for his pioneering work on forecasting methods. Recently, he challenged former Vice-President Al Gore regarding Global Climate Modeling – and today sent off another letter:
March 28, 2008
Honorable Albert Gore
2100 West End Avenue,
Suite 620
Nashville, TN 37203
Fax 615 327-1323
Dear Mr. Gore,
The extended deadline for the Global Warming Challenge has passed and, despite the fact that I have responded to all of your concerns to date regarding the challenge, you have not been willing to engage in a scientific test of your forecasts of dangerous global warming.
Despite our literature searches and our appeals both on the Internet and in our published paper on climate change, my colleague and I have been unable to find a single scientific forecast to support global warming. If you are aware of such a study, I appeal to you directly to reveal it to the scientific community so that it can be subject to peer review and so the public can see the scientific basis for your claims.
In addition we need to continue scientific studies. Thus, I pose this question:
“When and under what conditions would you be willing to engage in a scientific test of your global warming forecasts?”
I look forward to your responses. By your own words, the global warming issue remains an important one for the future of the world. Given the enormous expenditures on this issue, I hope that as a concerned and influential citizen, you will take an active role in encouraging the application of science to this issue.
Sincerely,
J. Scott Armstrong

A history of the Global Warning Challenge is provided at http://theclimatebet.com. It includes all correspondence between Scott Armstrong and Al Gore. The site will post all papers that purport to provide scientific forecasts of global warming. The papers must provide full disclosure on how the forecasts were made, as full disclosure is one of the basic principles of science.
