Facts on CO2

[Zephyr]

At 2000 PPM (give or take) humans start to feel side effects of CO2 like insomnia nausea and headaches.


There's so much stupid in this thread my head hurts.

Jazz, since in your books CO2 is all good, even at prehistoric levels before man, maybe you can talk to your pal Trump and get him to remove the CO2 scrubbers on all submarines, space craft and the ISS. He could save on the cost of building and operating without scrubbers and promote plant growth at the same time! It is the type of policy Trump would endorse.

Where does the product go that comes out of the scrubbers. It would probably make good fertilizer

Table B-1. Acute Health Effects of High Concentrations of Carbon Dioxide
Carbon Dioxide Concentration (Percent)/Time/Effects

17 - 30 / Within 1minute / Loss of controlled and purposeful activity, unconsciousness, convulsions, coma, death

>10 – 15 / 1 minute to several minutes / Dizziness, drowsiness, severe muscle twitching,
unconsciousness

7 – 10 / Few minutes / Unconsciousness, near unconsciousness
1.5 minutes to 1 hour / Headache, increased heart rate, shortness of breath, dizziness, sweating, rapid breathing

6 / 1 – 2 minutes / Hearing and visual disturbances
#16 minutes / Headache, dyspnea
Several hours / Tremors

4 – 5 / Within a few minutes / Headache, dizziness, increased blood pressure, uncomfortable dyspnea

3 / 1 hour / Mild headache, sweating, and dyspnea at rest

2 / Several hours / Headache, dyspnea upon mild exertion

Other research shows prolonged exposure at 1% will result in same health issues experienced at the 2 % level. Zephyr, instead of just saying the information presented is stupid, how about rather than just one level of exposure, with no exposure time and especially when you add "give or take" in your exposure levels on health effects, how about posting a source of your claim.

Human Pathology. Some of us have science backgrounds and don't require cognitive offloading for facts.

You guys are so precious. Human breath has a concentration of 4000 ppm.

People aren't passing out at hockey and basketball games.

How about you look up how many air exchangers are on a modern insulated building, and the rate of exchange.

And how much natural circulation there is on older buildings.

Hey Jazz, put a plastic bag over your head and see how long until you pass out as CO2 concentrations rise and O2 falls. Or is your human pathology different than everyone else.

BTW, Zephyr why was the buildup of CO2 on Apollo 13 so critical that they had to improvise a scrubbing system given your self declared superior knowledge?

You realize 2000 PPM is 0.2%, right?

Where am I saying high concentrations of CO2 are OK? I said the exact opposite.

My apologizes if I misunderstood this comment of yours which I initially replied to:

I thought you were saying my claim of health effects of high levels of CO2 were stupid.
