Should these scientists be ostracized for voicing dissent?

Debate is necessary. Global warming theory is not final. They have often made wrong predictions, and I dispute the interpretation of their results. They are mostly using models that are unproven; not enough time has been given to prove them. I think their is a lot about our planet we have yet to learn, and no one should think the jury is out and the verdict is reached in the global warming debate. It is just starting, really.
