Hi.
Is it possible that rising CO2 levels in the Earth's atmosphere might actually be able to cause a direct kill effect where low-level CO2 poisoning due to direct chemical toxicity could start killing humans and perhaps even other animals? (well, actually, it would cause a deterioration in global health, leading to early death, and making life bad in the meantime). It suggests even levels as low as 426 ppm (and we're at 400 ppm right now!) could be a problem, with 600 ppm being the level of a "stuffy room" (that can't be good for you, can it?):

Is this legit?
On the other hand, I've tried looking up information for the effects of low level CO2 exposure on humans (say, below 5,000 ppm) and have gotten what seem to be conflicting results, so I am not sure how valid this is.
Is this a serious concern? Note that this would be a direct kill meaning it is due to the CO2 gas itself, not the effects on climate.
