Featured in WSJ's Opinion Journal

Scott Armstrong’s challenge to Al Gore was mentioned in today’s Opinion Journal Political Diary (subscription only), which features commentary and analysis on US Politics by the Wall Street Journal.

Read up on the article by Taylor Buley below (reproduced with permission):

Weather Report

Al Gore thinks the climate crisis is so dire that he’s written a book, produced a movie and organized a world-wide music event to raise awareness. These have helped to make him a rich man, but is he willing to put his money where his mouth is? Don’t bet on it.

J. Scott Armstrong, a professor at the University of Pennsylvania’s Wharton School and expert on long range forecasting, has offered to bet Al Gore $10,000 that he can do a better job of predicting the future of climate change than the UN’s Intergovernmental Panel on Climate Change, whose forecasts of rising temperatures are cited in virtually every media account. Mr. Armstrong and a colleague, Kesten Green of the University of South Australia, examined the IPCC’s work for last month’s 27th Annual International Symposium on Forecasting and found it essentially valueless according to established principles of forecasting. “Claims that the Earth will get warmer have no more credence than saying that it will get colder,” concluded the two.

So what’s Prof. Armstrong’s own climate prediction? No change at all. “The methodology was so poor that I thought a bet based on complete ignorance of the climate could do better,” says Mr. Armstrong. “We call it ‘the naïve model.’ Things won’t change.”

Professor Armstrong is the author of Long-Range Forecasting — the most frequently cited book on forecasting methods — and Principles of Forecasting, which was voted a “favorite book” by researchers and practitioners associated with the International Institute of Forecasters. If Mr. Gore accepts his challenge, Prof. Armstrong has proposed that each man put $10,000 into a charitable trust at a reputable brokerage house. The winner would then choose a charity to receive the total amount.

So far, Mr. Gore — usually quite the opportunist — has balked at the opportunity to establish credibility with global warming skeptics. “Please understand that Mr. Gore is not taking on any new projects at this time,” read a note to Mr. Armstrong from Mr. Gore’s communications director.

Chorus does not justify climate prophecies

with one comment

Armstrong and Green’s work was featured in the Sydney Morning Herald’s July 7, 2007 article, “Chorus does not justify climate prophecies” by Michael Duffy:

The next week promises some excitement for those who believe global warming threatens our future. Today they can enjoy the Live Earth concert in Sydney. But on Thursday they will have to suffer ABC TV’s showing of The Great Global Warming Swindle, a British documentary sceptical of the orthodoxy…

Armstrong on Fox 29

Prof. Scott Armstrong from Penn’s Wharton School talks about how he can’t find any forecast model that predicts global warming. He has offered to make a bet with Al Gore over climate change. So far, Gore hasn’t taken him up on it.

Making predictions is a difficult business, Dr Kesten Green an expert in the field, says that many scientists when looking at the future impact and extent of climate change fail to take into account the basic principles of forecasting.    

Counterpoint is a program on the Radio National Network of the Australian Broadcasting Corporation, presented by Michael Duffy and Paul Comrie-Thompson.

News Coverage

without comments

Special Report with Brit Hume recently covered the challenge with the piece “One Expert Is Willing to Bet Money Al Gore Is Wrong About Global Warming.” Interview by FOX News Channel’s Matthew Hill.

Armstrong says he hasn’t gotten a response yet — and Gore’s office did not return a call from us asking for reaction to the challenge.

• Armstrong was also featured on American Family Radio News. Interview was done by Jim Brown, education reporter for American Family Radio News.

• Australia’s Courier Mail featured Dr. Kevin Trenberth as well as Armstrong and Green’s work in the article “Forecasts all up in the air.” Article by Bob Carter.

In a paper [presented] at the 27th International Symposium on Forecasting in New York this week, Scott Armstrong and Kesten Green audit the relevant chapter in the IPCC’s latest report. They find that “in apparent contradiction to claims by some climate experts that the IPCC provides ‘projections’ and not ‘forecasts’, the word ‘forecast’ and its derivatives occurred 37 times, and ‘predict’ and its derivatives occur 90 times” in the chapter.

Are you waiting for Gore’s response too? Why not digg us?

Today, the University of Pennsylvania newspaper “The Daily Pennsylvanian” covered Armstrong’s challenge on the front page (pdf). Click here to view the online version of “An Inconvenient Bet?”

Of note in the article is the author’s interview of an MIT climate scientist:

Carl Wunsch, a professor of physical oceanography and climate-change expert at the Massachusetts Institute of Technology, said that though different forecasting models show different outcomes for the planet as a result of global warming, most which are taken seriously by climate-change experts do show the world overall becoming warming and wetter because of human activity.

“They should be regarded as possibilities … that need to be taken seriously,” he said.

Wunsch also questioned whether someone who is admittedly unversed in the scientific principles of meteorology and geology could provide a better forecasting model than experts in these fields.
