evidence: Sen. Ron Johnson insisted again last week that he is not a climate change denier, but CNN’s KFile found video of him from just weeks earlier telling a Republican group that it is "bullsh*t." "I don’t know about you guys, but I think climate change is – as Lord Monckton said – bullsh*t," the Wisconsin Republican said, without uttering the expletive but mouthing it, and referring to British conservative climate change denier Lord Christopher Monckton. "By the way, it is." [...] Johnson’s views are at odds with scientific consensus that climate change is real and caused by human activities.
