You mean like John Clauser, the theoretical physicist, I presume? I wonder what Barack Obama or Henry Kissinger said about global warming.
I think a lot of this is down to the media especially in the West giving more coverage to skeptics (in many fields) than they do to scientists, simply because it's more entertaining and sparking of debate, to feel like goverment, big pharma, oil companies etc are all out for us. The concensus isn't that interesting.
