Newmark’s Door tells us that J. Scott Armstrong, a noted professor of marketing at Wharton, has taken a look at the “global warming models” and come to some conclusions:
We have concluded that the forecasting process reported on by the Intergovernmental Panel on Climate Change (IPCC) lacks a scientific basis.
1. No scientific forecasts of the changes in the Earth’s climate. Currently, the only forecasts are those based on the opinions of some scientists. Computer modeling was used to create scenarios (i.e., stories) to represent the scientists’ opinions about what might happen. The models were not intended as forecasting models (Trenberth 2007) and they have not been validated for that purpose. Since the publication of our paper, no one has provided evidence to refute our claim that there are no scientific forecasts to support global warming.
We conducted an audit of the procedures described in the IPCC report and found that they clearly violated 72 scientific principles of forecasting (Green and Armstrong 2008). (No justification was provided for any of these violations.) For important forecasts, we can see no reason why any principle should be violated. We draw analogies to flying an aircraft or building a bridge or performing heart surgery—given the potential cost of errors, it is not permissible to violate principles.
2. Improper peer review process. To our knowledge, papers claiming to forecast global warming have not been subject to peer review by experts in scientific forecasting. . . .
5. Forecasts are needed of the costs and benefits of alternative actions that might be taken to combat climate change. Assuming that climate change could be accurately forecast, it would be necessary to forecast the costs and benefits of actions taken to reduce harmful effects, and to compare the net benefit with other feasible policies including taking no action. Here again we have been unable to find any scientific forecasts despite our appeals for such studies.
Speaking of the peer review process, Warren Meyer at the ever readable Coyote Blog reminds us that, in fact, “peer review” has a fairly narrow function, and not the power most would like to give it.

Last Friday there was an article in one of the most read science journals, Science, entitled “Galloping Glaciers of Greenland have Reined Themselves In” by Richard A. Kerr.
Yes, as the title suggests, the article explains that a wide-ranging survey of glacier conditions across south eastern Greenland, indicates that glacier melt has slowed significantly and that it would be wrong to attribute the higher rates of melt prior to 2005 to global warming or to extrapolate the higher melt rates of a few years ago into the future.
She further reports that for some reason, the MSM just hasn’t managed to pick up on this story.
That shouldn’t come as a huge surprise to anyone who has followed the AGW issue from its beginning. The MSM has been one of its chief enablers. And it appears that the BBC has given up all semblance of impartiality in its coverage of AGW:
Londoners might have been startled last Monday to see a giant mock-up of a polar bear on an iceberg, floating on the Thames outside the Palace of Westminster. They might not have been so surprised to learn, first, that this was a global warming propaganda stunt and, second, that the television company behind it is part-owned by the BBC.
And finally, Czech President Vaclav Klaus fired at Al Gore again:
“I don’t think that there is any global warming,” said the 67-year-old liberal, whose country holds the rotating presidency of the European Union. “I don’t see the statistical data for that.”
Referring to the former US vice president, who attended Davos this year, he added: “I’m very sorry that some people like Al Gore are not ready to listen to the competing theories. I do listen to them.
“Environmentalism and the global warming alarmism is challenging our freedom. Al Gore is an important person in this movement.”
Klaus was speaking at the World Economic Forum and said that he was more concerned about the planned actions to combat the so-called problem than the consequences.
