My conservative friends don't think there's anything to be concerned about. My liberal friends are pretty green on such issues. Disagreements aren't over the science, perhaps, so much as opinions on the degree of impact and risk. It would all be entertaining discussion, I suppose, if the questions weren't about the fate of the world and life on it. :)
If we find ourselves agreeing with politicians on environmental subjects, there's little likelihood of scientific objectivity. If we have time to have an opinion, perhaps we might take the time to review the issues for ourselves.

Inspired by NPR's 'Science Friday' show, obviously.
