I also believe we should all be so muzzled.

What does Inhofe make of the NAS finding? Inhofe recognizes that the Earth is warming, but sees this as part of the natural cycle. Inhofe mentioned the Medieval Warm Period -- A.D. 1000 to 1270, when the Vikings grew crops in Greenland. So he doesn't buy this 12,000-year high. His office referred me to a piece University of Oklahoma geology professor David Deming penned for the Normal Transcript that noted, "The fact that the thermometer wasn't invented until the year 1714 ought to give us pause when evaluating this remarkable claim."

I remain agnostic on global warming, as I've seen good arguments on both sides. I know, however, that I never will be convinced that global warming is a scientific threat as long as believers put most of their energy into establishing orthodoxy and denying that reputable global-warming skeptics exist.

The Times' "mainstream scientists" line undermines the editorial's credibility, as it ignores the likes of MIT climate scientist Richard S. Lindzen, who argues that clouds and water vapor will counteract greenhouse-gas emissions. Ditto the 60 Canadian scientists who wrote to Prime Minister Stephen Harper that there is no "'consensus' among climate scientists."

Let me add the Copenhagen Consensus, a group of Nobel Prize-winning scientists and economists that looks at the best way to spend a hypothetical $50 billion to benefit mankind, rated fighting global warming as a "bad" use of money. That's amazing, when you consider the pressure that is put upon scientists to conform.

"Consensus" is another word for clique science. The good people are true believers, the bad people exhibit a "will to disbelieve." Editors used to salute healthy skepticism. Now some are global-warming Torquemadas.
