By all means, let's collect opinions on this, because opinions are absolutely the way to answer such a question.

Why we could even make it "scientific" by asking people to toss out a number and then could average them together using the Jeffersonian method.

5 PPM makes most people act like idiots. Unfortunately we have been far above that for millennia.

... yes?

Absolutely.  See the ppm average in Washington D.C. as a reference.

The vodak will affect the cognition long beforehand.

Everyone knows that. That's why the EPA is doing all they can to get as many particulates in the air as possible to drive out the CO2. They darker the air, the smrter you'll be!

Whatever the number is, we already passed it a while ago.

Doesn't matter, it's still going way higher. Maybe it will be better if we're all in a fog.

CO2 levels are very high on submarines and there's no sign of cognitive decline.

Worst case would be an environmental lead situation, where we don't notice because it doesn't affect fully developed brains but has deleterious effects on children.

If they would just use Brawndo to water the plants then the plants would become super powered and absorb all the excess CO2 no problem.

Already passed that point..  seems to affect the weak minded the most, which explains the liberal behavior patterns...

Probably.  But basic human cognition has already been trashed so badly by myriad other factors, we'll probably never know.

The air we breath OUT is about 40,000 parts per million carbon dioxide. It is no coincidence that this is the kind of level where toxicity results for mammals. That is why you start to get headaches at such levels. People with COPD have morning headaches caused by the built up of CO2 in their damaged lungs during the night. Even with healthy lungs, you would die a slow and agonizing death breathing re-cycled air without CO2 removal.

All animals that breath oxygen in and CO2 face problems at such levels. Fortunately, the CO2 quickly dissipates and amounts to only about 300 kilograms (less than a third of a metric tonne) per year. The the effects of breathing by poor people you have to add a few tonnes for cooking fires, rice growing and the like.

The world's poor still produce much less CO2 than an American street person (8.8 tonnes a year).

The average personal CO2 bill comes to 5 or 6 tonnes per person in Europe, 19 to 20 tonnes in North America, and over 50 tonnes in some Gulf states.

I knew quite a lot of this years ago. The rest is Google and Wikipedia.
