John Boehner of Ohio refused to allow it unless Gilchrest would say that humans have not contributed to global warming

Why the right goes nuclear over global warming | Most of the heat is generated by a small number of hard-core ideologues. | March 25, 2007

"Do you think it's been proven beyond a reasonable doubt that the Earth is warming because of man-made problems?" Of the respondents, 23% said yes, 77% said no. ... 2,000 UN scientists worldwide, find.. that the certainty on man-made global warming had risen to 90%.

So, the magazine asked the question again last month. The results? Only 13% of Republicans agreed that global warming has been proved. As the evidence for global warming gets stronger, Republicans are actually getting more skeptical. ...
...
How did it get this way? The easy answer is that Republicans are just tools of the energy industry. It's certainly true that many of them are. Leading global warming skeptic Rep. Joe L. Barton (R-Texas), for instance, was the subject of a fascinating story in the Wall Street Journal a couple of years ago. The bottom line is that his relationship to the energy industry is as puppet relates to hand.

The truth is more complicated — and more depressing: A small number of hard-core ideologues (some, but not all, industry shills) have led the thinking for the whole conservative movement.

Your typical conservative has little interest in the issue. Of course, neither does the average nonconservative. But we nonconservatives tend to defer to mainstream scientific wisdom. Conservatives defer to a tiny handful of renegade scientists who reject the overwhelming professional consensus.

National Review magazine, with its popular website, is a perfect example. It has a blog dedicated to casting doubt on global warming, or solutions to global warming, or anybody who advocates a solution. Its title is "Planet Gore." The psychology at work here is pretty clear: Your average conservative may not know anything about climate science, but conservatives do know they hate Al Gore. So, hold up Gore as a hate figure and conservatives will let that dictate their thinking on the issue.

Meanwhile, Republicans who do believe in global warming get shunted aside. Nicole Gaudiano of Gannett News Service recently reported that Rep. Wayne Gilchrest asked to be on the Select Committee on Energy Independence and Global Warming. House Republican leader John Boehner of Ohio refused to allow it unless Gilchrest would say that humans have not contributed to global warming. The Maryland Republican refused and was denied a seat.

Reps. Roscoe Bartlett (R-Md.) and Vernon Ehlers (R-Mich.), both research scientists, also were denied seats on the committee. Normally, relevant expertise would be considered an advantage. In this case, it was a disqualification; if the GOP allowed Republican researchers who accept the scientific consensus to sit on a global warming panel, it would kill the party's strategy of making global warming seem to be the pet obsession of Democrats and Hollywood lefties. ...
