Turns out that the more scientifically educated you are…wait for it…wait for it…the more likely you are to be critical and skeptical of both the evidence for climate change and the proposed solutions. So yes, critical thinking is important, and no, climate change skeptics are not (necessary) ignorant (or stupid or thick headed or whatever it is that people call skeptics. (There is an element of skepticism inherent in critical thinking. Thinking critically means (in some sense) always asking: prove it. And when you can’t prove it beyond a scientifically reasonable doubt, critical people shrug and say, ok, whatever, maybe later, maybe never, but right now I ain’t convinced.)
Note also that there is a very important aspect of this with respect to climate change and it has to do with causes and consequences. For climate change the issue of what to do about it is, for some reason, intimate with the actual changing of the climate. It need not be this way. (For commentary on why this happens to be the case, see Mungowitz’s commentary.) One can believe that the climate is changing, and even that humans are the primary cause, and still believe that nothing ought to be done about it (at least, nothing on a grand scale). This is rational given the cost and benefits associated with doing something about it. But, people that don’t want to do anything about it are routinely derided by those who would impose a grand world order to attempt to solve the problem.
Mungowitz also has some good commentary on the topic, below the fold (see link).
