dumber than dirt

clipped from scienceblogs.com DLC: I've already heard it from an acquaintance: "The world got cool after the volcano down near Taiwan exploded in the late 1800s [I assume he meant Krakatoa, but who knows?] and volcanoes make lots of CO2 so global warming is a hoax. Just watch how cooler it gets with the volcano in Denmark exploding and dumping CO2 in the air."* A few minutes later, after I pointed out that ash is the culprit for the cool summers and brutal winters after some volcanoes, and he said, "No, not the ash. It's the CO2. They won't let jets fly through it because there is so much CO2 that there isn't enough oxygen for the jets to burn."* A half hour later, I was significantly dumber and he was still an idiot. I took two aspirin and a scotch. * Very close to exact quotes.
