You will have quite some intellectual effects before you start coughing. In fact, where we are going with adding co2 to the atmosphere, people will be measurably dumber in 50 years.
Yes, really. Indoors we can easily get as high co2 levels as 1000ppm (starting from 400 something which we have outside now). That has in various studies been connected to upwards of 30% in cognitive decline in some tests like decision making. Simpler tests are also affected, but not as much. Here's an article about a Harvard study: https://archive.thinkprogress.org/exclusive-elevated-co2-levels-directly-affect-human-cognition-new-harvard-study-shows-2748e7378941/ https://archive.thinkprogress.org/exclusive-elevated-co2-lev...
Dry ice in the car without the windows down seems like a bad idea.
- at_a_remove 6y agoI've done it tons of times. Part of having the stuff wrapped up and insulated is that it isn't sublimating like mad.
- bjoli 6y agoYou don't really notice 1000ppm, and unless you have some ventilation going you can probably reach that quite quickly in your car. I am not saying that it didn't work out or that it was reckless. Just make sure you have adequate ventilation.
- at_a_remove 6y agoJust as an indicator, you can get up to 5,000 ppm with two passengers in a car after an hour's worth of driving.
- bjoli 6y agoExactly: 5000ppm means significantly worse decision making and crisis response. How much more co2 does sublimating dry ice put out? Well packaged probably not that much, but certainly more than another person breathing beside you.
