This is trouble for the GOP. By the time 2016 rolls around, 2015 will have blown away the record for warmest year, making any claims of a hoax look insanely stupid.
Not that that matters to the conservative true believers. The Republicans been feeding their ultra-low-information base the "global warming is a hoax" conspiracy theory for years, so now their idiot base has incorporated it into their religion, and demands that all candidates bow down to the sacred denialism idol.
However, no candidate dares go on the national stage spouting such a stupid conspiracy theory, as he'd be laughed out of the room.
So now all the GOP candidates have to walk a fine line, like Jeb's "I'm not a scientist" mumbling. Their brainwashed base demands denialism, but denialism is electoral poison to all the normal people.
Life is good. Pass the popcorn.
