They mostly just make fun of it rather than outright say it isn't real. Three episodes stick out for this: Two Days Before the Day After Tomorrow, Goobacks, and ManBearPig. They don't really even mock global warming itself in these episodes, but people who exaggerate it's effects and people who take it way too seriously.
