I agree with you - it is often the exception rather than the rule, but that does not mean we can discount skeptics because they are a minority. In this case, there are enough skeptics, and enough sound logic behind them, that there is reason to be skeptical (again, go through all the quotes in the wikipedia entry I linked and see if you can dismiss all of them).

I would never propose that we should or should not believe in AGW. What I propose is that we should be skeptical to both sides until we have the hard, undeniable data. Again, I would emphasize there is a huge difference between a fact and a hypothesis. Many studies have already been proven wrong, temperatures have not risen as dramatically as expected.

In the long run though it makes little difference either way as I have stated. Regardless of AGW, we should pursue green technology because we are running out of non-renewable energy, and advancing energy research is perhaps the most important scientific field at this point in time.
