Now, if some scientist comes up with something that overthrows a major part of a field of science, that scientist is going to be famous, so there's a big incentive to refute AGW if possible.
This idiotic sophism has been so often refuted, that any attempt to do so again seems futile. In fact, if I were in a fouler mood, it would elicit the well-deserve soup of expletives in your direction. But hey, I am not there yet.
So once again, any self-selected group cannot be considered honest if they are not open to criticism or introspection from outside experts. The AGW camp is just such a group. If you are one of them, you are a "peer". If you are a renowned world-expert on a subject on which these "peers" make statements, but you yourself are not an expert on their entire subject, when you ask questions on the field of your expertise, they brand you a denier, bring out the tar and feathers and drag your name through the mud. So not only are they not open to any outside criticism, they, under the threat of destroying people's careers, actively discourage any outside experts from questioning their "findings."
This is a classic http://en.wikipedia.org/wiki/N... type of logical fallacy.
I am glad we've covered that so that the next rabid dog foaming at the mouth, because his favorite politicians or celebrities told him to support AGW, can repeat this fallacy again.
