Right-wingers sure love to mock science, don't they? Here's another one (a Pajamas Media/New York Post wingnut), who thinks his own ignorance is absolutely hilarious.
To review, global warming and climate change are terms that describe two different phenomenon. It's really not that complicated, if you're an upright walking biped who breathes through their nose.
And the next time some winger pulls the 'CLIMATE CHANGE' HAHAHAHAHA card, remind them it was Frank Luntz who encouraged that terms use.
