Monique: Thank you for posting links to the two reviews on climate change, in the sticky thread. I am heartened to see that in fact, the PF are not comprised of global warming skeptics, as was my first impression. Both reviews lie with consensus opinion. It's been my experience that all "anti" warming reviews and papers tend to come from Shell, Exxon, etc. or those in their employment. Should you come across any reviews that oppose the consensus, I would be interested to see them, and to see who has put them together. I would like to mention one thing. You introduce these two reviews with the note that there is "controversy" in the scientific community ... and it is my understanding that this is not an accurate reflection of the state of things. For example, see: http://www.sciencemag.org/cgi/content/full/306/5702/1686 This link relates a survey of climate change literature. Of 928 papers analyzed, not one opposed the consensus opinion. There is no controversy among climate scientists, in my understanding.
