This guy is such a pompous ass. He is Al Gore re-born. Like most alarmists he refuses to debate, the presents ludicrous scaremongering ideas that any high school science teacher would laugh at.
But Penn State investigated him for scientific fraud and wrong-doing (climate gate) and concluded (in an internal CLOSED investigation) that he had done nothing wrong.
And of course we know Penn State would never try to cover up wrongdoing to protect their own ass....no way........
