This article on a conference sponsored by the free-market Heartland Institute points out that, while there is a large scientific majority on the side of anthropocentric global warming (AGW), it's not a complete agreement. Despite accusations by people like Al Gore that the only objectors to AGW are tools of corporate interests, there is in fact still some scientific pushback against several AGW lines of argument.
COMMENT: I'm not saying the contrarians are right. But I'm glad they are still getting some coverage. Any scientific theory on which we're talking about basing a gigantic shift in the global economy must be continually forced to buttress its position and address any negative evidence.
