30,000ppm might kill some animals. You breathe out 30-40ppk. Doesn't start hurting until much higher.

300ppm is only double extinction levels.

Balance is something that is seriously missing from the current narrative

Fair enough. But they've found even slight increases in CO2 can affect brain function. So humanity could have an IQ meltdown as CO2 increases lol

It certainly seems to have a wild effect on my liberal ex-friends. I'm going to have to ask for a source on your statement.

Even in a closed room with no ventilation at night, it can cause decreased brain function

Interesting study. Relevant to indoor spaces with poor ventilation, for sure.

I notice that they did not control for time based adaptation to the changed CO2 levels.
