Bump. (apologies)
I thought this was a good summary of the AGW/no AGW debate, from a scientifically biased point of view. I say biased because, in this day and age, it has been politically divided, with the d's on one side and the r's on the other. The scientist credited with coining the phrase "global warming" back in the '70's was interviewed for the article, so it's good for a historical perspective as well.
I like the commentary below on this same page, where there still reside individuals ostensibly in the scientific community still denying the fact that temperatures are rising, whatever the cause.
