LC50 for CO2 is 100,000 ppm. OSHA limits are 5,000 ppm. 2009 Ambient atmospheric levels are 389 ppm. Like I said, double the ambient level and it will have no noticeable effect on human breathing!
This whole business comes back to politically trumped up effects on global warming.

Oh come now! This is not a serious argument. If I put you in a Japanese hot spring bath for a half-hour you would probably find it pleasant. If a million acres of Georgia land were inundated with 50 deg C water filled with sulphur it would be a disaster. Please, give us a break. This is a science forum. You can't just toss out the last hundred years of climatology and substitute a statement about how you would fare if you were put in a room with a lot of CO2. That's got nothing remotely to do with climatology, and you know it. - Jed
