“Have the climate models been successful in predicting anything? They, of course, predict substantial global warming. This is not surprising given the expressed belief of some of the model builders in the global warming hypothesis and the many parameters in the model that need to be introduced. However, the models also predict unambiguously that the atmosphere is warming faster than the surface of the earth; but all the available observational data unambiguously shows the opposite! Truth in science is always determined from observational facts. One finds the truth by making a hypothesis and comparing observations with the hypothesis. It is absolutely essential that one should be neutral and not fall in love with the hypothesis. If the facts are contrary to any predictions, then the hypothesis is wrong no matter how appealing. "Truth by Assertion" is not science.”

Context: If an economist uses a complicated model to predict just about anything, you can ignore it. By analogy, a doctor can’t tell you the exact date of your death in 50 years. But if a doctor tells you to eat less and exercise more, that’s good advice even if you later get hit by a bus. Along those same lines, economists can give useful general advice on the economy, even if you know there will be surprises. Still, be skeptical.

Global Warming: Natural or Manmade? http://www.drroyspencer.com/global-warming-natural-or-manmade/

"The Bubble of American Supremacy" in The Atlantic Monthly (December 2003), p. 63 - 66 http://www.globalpolicy.org/empire/analysis/2003/12supremacy.htm
Context: The supremacist ideology of the Bush Administration stands in opposition to the principles of an open society, which recognize that people have different views and that nobody is in possession of the ultimate truth. The supremacist ideology postulates that just because we are stronger than others, we know better and have right on our side. The very first sentence of the September 2002 National Security Strategy (the President's annual laying out to Congress of the country's security objectives) reads, "The great struggles of the twentieth century between liberty and totalitarianism ended with a decisive victory for the forces of freedom and a single sustainable model for national success: freedom, democracy, and free enterprise."
The assumptions behind this statement are false on two counts. First, there is no single sustainable model for national success. Second, the American model, which has indeed been successful, is not available to others, because our success depends greatly on our dominant position at the center of the global capitalist system, and we are not willing to yield it.
