Kudos to Rep. Daryl Metcalfe, Chairman of the PA House Environmental Resources & Energy Committee, for being the adult in the room at yesterday’s hearing on so-called climate change (i.e. man-made global warming). Metcalfe, who is a “denier” that mankind is catastrophically causing the earth to toast, arranged a hearing on “Pennsylvania CO2 and climate.” He included six witnesses who testified they believe in the fairy tale of man-made global warming, and five witnesses who don’t, to offer their best evidence for/against. That’s about as even as it gets. Yet eco-leftists, like the executive director of PennEnvironment, compared those (of us) who hold an opinion other than his, to Nazis.
