Here's a snippet from Michaels's column:
So here's what Al told Grist Magazine about global warming: "I believe it is appropriate to have an overrepresentation of factual presentations on how dangerous it is, as a predicate for opening up the audience.""Overrepresentation of factual presentations"? There's a graceful euphemism for lies. I guess he can get away with this because no controlling legal authority has said he can't.
It would be nice to think he came up with this de novo. But exaggeration of global warming has long been considered virtuous.
