John Eidson, electrical engineer: Dr. Happer is one of the best of the best when it comes to knowing about the atmosphere. But because he has doubts about man-made global warming theory, the alarmists who try to scare kids about the climate don’t like him and say ugly things about him. He doesn’t let that bother him. He just does what he’s always done—give his good faith scientific opinion and let the people who don’t like that he speaks his mind say whatever they want. See this short, interesting video. Enjoy life and nature.
