First of all, anything that adds cost to energy prices right now is going to be viewed with a great amount of concern. And so, you notice the cap and trade debate has kind of faded into the background and it’s unclear what that would look like when and if it reemerges. I would also state Sen. McCain supports that approach, but how you do it is really important....you can argue that the world, the globe is warming as it always has for natural reasons. But I think the weight of the science indicates that at least some of it — you know you could argue it’s half a percent or something more substantial, you know — is caused by human behavior. So there are some things that we can reasonably and voluntarily do to reduce the human impact.... in the wake of this energy crisis, where people are, you know, struggling to pay the bills, that debate on cap and trade has fallen to the background for understandable reasons.
Bush waited until after the election to backtrack, but we're seeing it beforehand.
UPDATE: Some good news though - Palin is now waffling about anthropogenic climate change instead of outright denying it, and denying that she previously denied it. Progress through lying! (Though her statement that you need to do something about it regardless of whether it's natural or artificial hardly lends confidence in her ability to analyze.)
