Speaking of things I’d like to offer some insightful contribution to but don’t have time, do not miss yesterday’s post on RealClimate about skepticism — or rather, "skepticism."
Climate skeptics are more accurately called contrarians. Everything but the most extreme philosophical skepticism countenances accepting the consensus view of experts as likely to be true. Anything else would be crippling, since 98% of our personal knowledge is taken on the authority of experts (ever seen an atom?) rather than from direct experience.
I’ve written some on related topics before, and hope to again, but for now just go read RealClimate — and read the comments too, there’s some great discussion.
