Get a CO2 sensor, and you will see CO2 levels spike massively in occupied rooms with poor ventilation. Indoor CO2 levels can easily exceed 4x the normal outdoor level. Because of this, and critical thinking, I don’t believe for a second that a global rise in CO2 has any direct effect on our behavior. I could be convinced that increasing time spent indoors (and online) does, though
Typical CO2 concentrations:
- Outdoors (2024): ~430ppm
- Outdoors (2000): ~370ppm
- Indoors (depends on ventilation): 800ppm ~ 2000ppm+
2022 Polestar 2 with all the options. I think the Polestar is super cool, and I didn’t want to replace my Tesla with another Tesla. I got it used last August for $36k, because used rentals were flooding the market. This car goes for $70k new, but it is not worth anywhere near that
