This is why they don't believe in climate change/global warming, either

Poll: Majority of GOP primary voters don't believe Obama was born in the U.S.

If 51% of the likely Republican primary voters (that is heavily weighted now, in a lot of states, toward the Mind-Empty, er, Tea Party, voters) believe that Barack Obama wasn't born in the U.S. of A. (in Hawaii), then how in the world can we expect these Fox News disciples to grasp the nuances of climate change?

Answer: we can't. We need a massive heat wave to devastate flyover country to jolt them out of their complacency, on the order of what happened in Russia last summer.

Sorry to be so blunt, but it's the only thing that might make an impression. But they'd probably just end up blaming it on the "weather", anyway.
