right, CO₂ has become a (inter-)national psychosomatic obsession of the privileged class, but no one should be worrying about CO₂ at all, unless you work in some very specific industries. you'd need a ppm of 50,000-100,000 to feel any real effect from CO₂, or to see noticeable greenhouse effects from it. it's today's equivalent of fearing power lines or MMR vaccines. it's fretting on something that feels tangible and controllable, without delving deeper and examining the (social and mass) media-driven presumptions underlying those fears. pollution, on the other hand, is a real concern. that's stuff like radon, VOCs, methane, dioxins, and SOₓ emissions. as such, one thing we should be doing with vigor and relentless focus is phasing out coal plants (if we were actually putting our priorities in the right place) rather than worrying about the sideshow that is carbon emissions.

This article is a about indoor air quality where co2 is a proxy measure of stuffiness... It took me a sec to figure out you were talking about something totally different.

> you'd need a ppm of 50,000-100,000 to feel any real effect from CO₂ Have you used the wrong numbers here or are you advocating some novel and unorthodox ideas about CO2? Did you mean 5,000-10,000? Because as far as I can tell, those (5-10%) are the levels where people start to do things like lose consciousness from CO2 poisoning.

  No, I think he's correct based on the study linked from this other interesting comment here: https://news.ycombinator.com/item?id=34651244 https://news.ycombinator.com/item?id=34651244

    The linked study directly states that loss of consciousness occurs after ~7 minutes of exposure to 10% CO2.

      And that's the obvious threshold. After all, no one can tell whether they've been drinking until they wake up on the floor, right?

  nope, that's exactly right. at 5-10% you feel real effects, not at 1200ppm or 3000 or any other psychosomatic level. "poisoning" is a needlessly loaded word in this context. CO₂ is literally critical for life. just about any molecule/compound at those concentration levels (outside of those we co-evolved with, like nitrogen) will have noticeable effects as well.
