Not any time soon, as far as I'm aware. According to [0] a fancy article from Business Insider, the rate of increase is 2ppm/yr, on average.
But many studies suggest cognitive effects of CO2 levels as low as 1,000ppm. See: https://ehp.niehs.nih.gov/doi/10.1289/ehp.1510037 https://ehp.niehs.nih.gov/doi/10.1289/ehp.1510037

- baxtr 8y agoThanks! So 2ppm/year gives us another 300 yrs to top 1000 ppm. I guess we’re safe for now! Rock on
- Retric 8y agoYour local air has higher CO2 than the environment even today it can reach 1000 ppm with poor ventilation. So, it's likely to be an increasing issue long before we hit 1000 ppm outside.
- graeme 8y agoIndoor air is 1000+ in most places that don't actively ventilate. The higher outside air is, the less effective ventilation will be.
- dTal 8y agoIt won't always be 2ppm/year. The rate increases yearly. We can expect 1000ppm somewhere around 2100, perhaps a bit after. Of course 1000ppm has far nastier effects than just those on human cognition.
