Scientific American: Are you a global warming skeptic?

For the intellectually curious out there -
This series of Scientific American blog articles (with lots of reader comments) asks the musical question: Are You a Global Warming Skeptic?
Part One, Part Two, Part Three, Part Four.

Also, a (previously mentioned) three-part article on "The Climate of Man" from New Yorker magazine: Part One, Part Two, Part Three.

Naturally you are free to remain a skeptic, even after reading the articles.
Thank you Darren. Very interesting read. A confrontation of the two views is rare to read in the media nowadays.
