The sun, natural cycles, bad measurement, faulty science....all are viable counterpoints to Climate Change. My biggest problem (with both sides) is that they both try to shut down the debate. GOP pol's have made up their mind and do nothing but shut down climate change activists. Dem's have made up their mind and do nothing but shut down dissent. Like most things the science debate has become to embroiled in politics. If we (the GOP) are so confident the science supports our conclusion then put our 5 best scientists on the stage with their 5 best and let's have a full science debate.
