Take Newt Gingrich, for instance. Only four years ago he was willing to sit on a love seat with Nancy Pelosi and film a commercial for a campaign headed by Al Gore. In it he explained that he agreed with the California Congresswoman and then-Speaker of the House that the time had come for action on climate. This fall, hounded by Morano, he was forced to recant again and again. His dalliance with the truth about carbon dioxide hurt him more among the Republican faithful than any other single “failing.” Even Mitt Romney, who as governor of Massachusetts actually took some action on global warming, has now been reduced to claiming that scientists may tell us “in 50 years” if we have anything to fear.
In other words, a small cadre of fervent climate-change deniers took control of the Republican Party on the issue. This, in turn, has meant control of Congress, and since the president can’t sign a treaty by himself, it’s effectively meant stifling any significant international progress on global warming. Put another way, the various right wing billionaires and energy companies who have bankrolled this stuff have gotten their money’s worth many times over."
