Fine- have this debate. Not in front of Congress, not in front of Pruitt, not in front of the President. Have it in front of scientific societies and communities around the world. They are able to understand and evaluate the debate, not Pruitt, not Congress, and certainly not the President. Believe it or not, that is NOT a slam of their intelligence. There are many smart people who are not well versed in science- why ask them to decide the debate? Let the experts decide and then LISTEN to the consensus that will emerge.
