I don't like Bill Nye anymore.
Meh, he didn't say anything too terribly problematic.
Would it be better if the U.S. produced its own energy? Yes.
Would it be great if American scientists discovered new forms of energy? Yes.
Is it good to teach children math and science so that they may become great scientists? Yes.
Is sustainable energy a good thing to shoot for? Yes.
Is the earth still going to be around no matter what? Yes.
Should we want to take care of the planet for our own sake? Yes.
Does the thickness of the earth's atmosphere really have much to do with the matter of whether humans affect it or not? I doubt it.
Are Nobel Prizes ever given to discoveries that are false or misrepresented? Yes, I think a few have, Nobel committees being fallible.
Are "green" forms of energy like wind and solar really a viable replacement for fossil fuels? Not hardly. But he didn't seem to think they are. I wish he'd mentioned nuclear.
That aside, I can't dig up any dirt on Tyson or Feynman.
I don't know why you should want to. Only an idiot would only value the achievements and statements of a person if that person is perfect and has no "dirt" on them.
