No, Pascal's Wager is foolish since you could not possibly select the correct god from the myriad of gods available (Christianity, Islam, Buddhism, Hinduism, etc) given that belief is mutually exclusive. At any rate it's not the same thing. The precautionary principle is an insurance sale, not some metaphysical nonsense. And you're being unfair about your characterization of Global Warming. It is just not any doomsday scenario. There's enough reputable scientists getting their panties in a knot that it should be cause for concern.

It is not being metaphysical in nature that makes Pascal's Wager nonsense. It is that it demands action without sufficient rational foundation. The rational reaction to a possible crisis in which one lacks information is not to jump immediately away from what looks like the scariest outcome. That tends to make things worse. The right reaction is to focus on research until a decision absolutely cannot be avoided--and even then, make the minimum decision the evidence warrants. I view that as the case here. If the evidence is sufficient to convince and act on, okay. Act on it. But if it is not, the stakes being high do not change anything. By all accounts, there's time yet to be more certain, so let's take the time and be more certain. Incidentally, "a lot of reputable scientists are concerned" is a statement about state of the evidence, and not a very persuasive one to me. I know a thing or two about simulating complex systems; a non-predictive simulation, a theory concerning a single variable input, a loose-but-not-awesome correlation? In a complex system, that really is street preacher kind of evidence. Absolutely it warrants theoretical concern; follow that line of research. But as a call to action? Nah. Call me when you've got a robust enough model that you can use it to win wars or make money, and we'll talk.

  Well, the problem here is that we're talking about a possible run away greenhouse effect that will condemn most of humanity to death. The point being is that you must act now in order to stop it and that this is the rational approach even if you do not have conclusive evidence. Your gamble is an unacceptable risk, or so the principle would say. I spent a couple years living in mainland China with pollution so bad that you literally could barely see across the street. On many clear sky days you could look directly at the sun with no issue. I flew over the country to different cities dozens of times and always the entire country was covered in a thick smog for thousands of kilometres. We really have no idea here in North America of the scale of things going on. And China is going to massively increase their emissions in the coming decades.
