While I’m no fan of Bill Nye or the climate change crowd, I do have to say that I should be offended that just because his diploma was a BS that he, and others like him, can’t be self educated in meteorology or any other discipline. From the BBT, we constantly hear Sheldon put Howard down because he doesn’t have a PhD, only a Masters in Engineering, as though that makes someone lessor in capability. I think that Bill Nye’s bow tie is on too tight and has cut the oxygen from getting to his brain, but that doesn’t mean that an engineer can’t also be well versed, and self taught, in any of the sciences.
Aha! That only leaves CO2 in his system.
Maybe he's a huffer.
I think the key is to acknowledge that having a degree in science (I have a BS in Chemistry) does not make you an expert in every science, but does allow you to view data and theories critically using the techniques you have learned in your specialty.
Even more important, is to keep in mind how much you don’t know, and that you are capable of being wrong and misinterpreting things.
I detest Bill Nye for ignoring both of these caveats.
