46 years at a government job? He should be a poster boy for the difficulty of firing the worse than incompetent. He actually worked hard at making the lives of most Americans worse than it could have been otherwise.
NASA supported and encouraged this "scientist" for all these years while he distorted facts to suit his own personal crusade. It is a blight on that organization. I deeply resent that my tax dollars went toward his financial support. If I were elected President, I would make it one of my aims to find out who in NASA has been protecting Hansen all of these years, and make sure their careers were terminated immediately.
