This was not the article to read while boarding a plane for a conference.

I am something like a canary in the coalmine here. I actually get drowsy and start nodding off despite herculean effort in some poorly ventilated rooms.
Interestingly - and this is a huge conceptual leap here that would need examination - but it describes the kind of neuronal change as "disorganised activity"/reduced cohesion. This is also found in people with ADHD and "night owls" with sleep phase delay disorder - likely poor neuronal communication in the parts of the brain contributing to altertness and attentiveness at baseline in such individuals I am the poster child sleep phase delay disorder person. Connected issues? Another reason ADHD kids would do worse in a class than at home or outside? |

Current atmospheric CO2 levels are at about 415ppm. This is the foundation upon which all interior CO2 levels are based on and are going to raise as the atmosphere becomes more saturated. It's beginning to seem very unlikely we're going to avoid reaching atmospheric 600ppm as our states commit deeper and deeper into an adaptation ideology of handling global warming. We've already got things like O2 bars and canned air that commodify oxygen; I'm thinking it's just a matter of time before celebrities start outfitting their homes, carrying around their own Oxygen concentrators. At first, I'm sure it will be presented as a kind of trendy thing. I can already see Elon Musk smugly explaining how having his own source of fresh O2 helps him to be more innovative and productive. The Kardashians chatting on The View or some shit how it helps keep them looking young and ready for the world.
Meanwhile, the rest of us will be called greedy for wanting our brains to work. |

It's not about more oxygen, it's about less CO2. Oxygen supplementation may be trendy, but what we really will need indoors are CO2 scrubbers. I expect within 50 years they'll join furnaces and AC units as a standard household appliance. That is, if we're fast enough to deploy them before we're too stupid to realize we need them.

True. Apologies, I thought o2 concentrators scrubbed co2 through zeolite but it looks like they just scrub out nitrogen.
Edit: Though now that I think about it. Eventually it's goign to become an oxygen problem. Hooray! |

But you have to admit it's a shame it's come to this, yes?

We could just put a bunch of plants in our homes and offices.

Maybe, but I wouldn't put too much hope in that once the numbers get high enough. This study uses 6 offices about 10-12 m2 each. 3 plants (in 11 inch pots) removed about 14.3 ppm per plant in an air conditioned setting and 32ppm per plant in a non air conditioned setting. It's obviously something we should definitely be doing already and I'm sure there will be more efficient plants that can be probably be used, but if we're talking about sequestering with 3-7 plants per 100ppm and co2 levels are getting up in the thousands you're going to run out of space for humans. Also, I'm wondering if we're going to run into an issue where plants start to drown in the CO2... Which is something we're starting to see happening in agriculture as nutrients drop in response to higher CO2.
