Well, to be honest with you, I don't have much time for either side. I think the Liberals, but more particularly the Left have done a lot of damage to AGW acceptance simply by trying to integrate into their own economic mumbo jumbo, and trying to beat conservative elements over the head with it. They've made one of the supreme challenges of humanity at this point of time and politicizing it for their own ends). The conservatives, on the other hand, are often just people easily manipulated by large commercial interests who want to delay significant responses to AGW long enough to maximize profits. That's why the fossil fuel companies fund crap "think tanks" like the Heartland Institute, because they serve to give conservative and libertarian types a pack of memes to trot out every time the topic of global warming comes up. A pox on both their houses, I say. Both groups are populated by idiots and demagogues.
To my mind, the time has come to simply look at the best way of dealing with the problem. For me, the simplest way and the way that it is the most market oriented is carbon pricing. Start upping the price of fossil fuels, thus allowing market forces to concentrate investment on alternatives. I don't even care if governments pocket the cash. The whole point isn't reinvestment of carbon taxes, but rather to create an artificial scarcity. This solution should be eminently favorable conservatives and libertarians, because it favors their economic approach, but of course, it will cost the likes of the Koch Brothers money, so the game goes on.
