Key point made:
Money is given to scientist who support the Global Warming theory.
Does it really matter that he owned the Weather Channel? Personally I don't see how that rolls over into him being an expert on global warming, so much as it makes him a savvy business man.
I get that it's hard to find scientists to go on the record, who aren't stained by fossil fuel dollars... but that would feel a lot more persuasive to me.
