Al Gore Won’t Bet on Global Warming Because He’s Wrong (Guest: Kesten Green)

February 1, 2018

In 2007, forecasting experts J. Scott Armstrong and Kesten Green offered Al Gore a wager concerning future temperatures. The time is up and had Gore taken the bet, he would have lost.

In 2007, Professor Kesten Green of the University of South Australia Business School, and his colleague J. Scott Armstrong at the University of Pennsylvania offered a wager to Al Gore. At the time of the wager, Gore was touting his book and movie An Inconvenient Truth. The bet centered on whether the temperature would be higher ten years from now if carbon dioxide continued to rise, would it rise consistently, and how much the warming would be.

Green and Armstrong bet there would be no noticeable change from the past with temperature rising and falling naturally and following no discernible upward trend.  If Gore had taken the bet, he would have lost. Green discusses the bet and how the Intergovernmental Panel on Climate Change continually violates the principles of scientific forecasting. They discern the IPCC’s flawed methodology may explain why its projections are regularly wrong
