Here at RealClimate we understandably have an intense interest in the positions of the Presidential and Vice-Presidential candidates regarding global warming and carbon emissions. What the stance bodes for future action on climate change is consequential in itself, but beyond that the ability to use sound science in this case serves as a bellweather for the candidates’ whole approach to science. Whatever else you can say about the candidates, it has been encouraging that both John McCain and Barack Obama favor mandatory action to reduce US carbon emissions.
But, enter Gov. Sarah Palin, McCain’s pick for VP. Palin’s position on global warming has been stated quite clearly in this recent interview with the publication Newsmax , where she says “A changing environment will affect Alaska more than any other state, because of our location. I’m not one though who would attribute it to being man-made.” How is this to be reconciled with McCain’s position? Do they just agree to differ? What does this bode for future actions if McCain were to win the election, especially in view of the fact that, in a Cheney-esque way, Palin is likely to be put in charge of energy policy? The recent vice-presidential debate sheds some light on the issue. A full transcript of the debate is here.
