How stupid is CNN’s Rick Sanchez? Jon Stewart devoted the better part of a segment to mocking his ignorance. We watched Sanchez act like a control freak, misplace Hawaii on a map, and express confusion about the conversion of meters to feet. Seriously, he wanted to know what meters meant “in English”.

Well, Einstein’s back with a vengeance. For some reason, CNN decided to let him talk science again. With equally embarrassing results.

SANCHEZ: I was just asking Chad, how can you get a volcano in Iceland? [Myers laughs]. Isn’t it too- when you think of a volcano, you think of Hawaii and long words like that. You don’t think of Iceland.

MYERS: Right.

SANCHEZ: You think it’s too cold to have a volcano there. But no! There it is.

MYERS: Look at that.

SANCHEZ: What is this? Explain-

MYERS: That is a-

SANCHEZ: Go- take us through these pictures.

MYERS: That is a plume of ash coming out of the top of [a] volcano, going straight up. Tens-

SANCHEZ: What’s that white stuff though? It looks like clouds.

MYERS: Tens of thousands- that’s just a cloud.

SANCHEZ: Oh, okay.

MYERS: Yeah. The volcano is going off, but there’s just regular weather happening underneath it. This thing is going tens of thousands of feet in the sky, and it is going right into the flight path of an awful lot of airplanes.

Yes, amazing that an island perhaps best known for its volcanic and geothermal activity could actually have a volcano.

By the way, Iceland? Yeah, formed by volcanic eruptions. Which this local Mensa chapter president would’ve known had he taken some time away from Twitter to read, oh, Wikipedia. In fact, the same website lists 43 active and extinct volcanoes in Iceland.

Video of the delicious segment here. I’ll bet this guy lectures conservatives over skepticism about global warming, too.
