She was on record as supporting Cap and Trade back in 2007. She is now on record as being against it as of 2009.

She also supported in in the 2008 VP debate. Given that the idea has become VERY unpopular with the public, I am as skeptical of this "conversion" as I would be if Romney suddenly came out with strong statements against health care mandates. The problem is that she has never repudiated her earlier stand. Here is a a quote from a December 2009 Washington Post piece she wrote: http://www.washingtonpost.com/wp-dyn/content/story/2009/12/08/ST2009120803542.html?sid=ST2009120803542

"That's not to say I deny the reality of some changes in climate -- far from it. I saw the impact of changing weather patterns firsthand while serving as governor of our only Arctic state. I was one of the first governors to create a subcabinet to deal specifically with the issue and to recommend common-sense policies to respond to the coastal erosion, thawing permafrost and retreating sea ice that affect Alaska's communities and infrastructure."

From the same article: "But while we recognize the occurrence of these natural, cyclical environmental trends, we can't say with assurance that man's activities cause weather changes. We can say, however, that any potential benefits of proposed emissions reduction policies are far outweighed by their economic costs."

No, we cannot say that "any potential benefits of proposed emissions reduction policies are far outweighed by their economic costs". First of all, CO2 is NOT a pollutant. CO is but not CO2. Secondly, "policies" aimed at CO2 emissions do far more harm than good.
