Senator Bernie Sanders has long been one of the strongest voices for aggressive action on climate change on Capitol Hill, and Bill Nye has long been one of the strongest advocates for pro-science policy in the United States, so it was quite disappointing that their recent Facebook Live discussion about the need to take bold action to reduce carbon pollution was so short on substance. It was quite sad to see Nye continue to peddle the bogus notion that with enough evidence, Donald Trump can change his mind about the importance of combating the climate crisis.
