"I believe in evolution and trust scientists on global warming. Call me crazy," GOP presidential hopeful and former Utah governor Jon Huntsman recently tweeted. You've got to hand it to Huntsman - he sure knows how to endear himself to folks who won't vote in the Republican primary.

Huntsman has said that he fears that the GOP will be perceived as the "antiscience party." That is, he gave a nod to Democrats' conceit that theirs is the party of science. Why? Because the Dems don't tolerate questions about evolution or global warming.

For the record, I believe in evolution. But I also have respect for those who see God's handiwork in the process -- and see little reason to try to marginalize those with different personal beliefs.

I also share the skepticism voiced by a number of scientists -- yes, scientists -- who reject global-warming orthodoxy in defiance of a political/academic machine that enforces submission to one view. Those who do not agree with alarmist predictions on climate change do so at their careers' peril.

As then-Delaware state climatologist David Legates told me in 2007, he would tell students who were not global-warming true believers, "If you don't have tenure at a major research university, keep your mouth shut."
