CO2 levels don't actually poison us though. The problem isn't CO2 levels per se, but the effect they have on global climate change, by trapping more heat. If less light gets through, then the planet cools, even if CO2 levels remain high. If temperatures stabilize or drop by 1.5C, then plants should eventually be able to remove the excess CO2, as long as we stop increasing our output. OTOH, the decreased amount of light getting through might make solar panels less efficient, and may reduce plant growth since they kinda need sunlight too. Sooooo...
High levels of CO2 are 100% toxic, why would you ever suggest otherwise?
Technically accurate, but not accurate in any meaningful way in this context.
The planet would be unlivable LONG before CO2 levels got high enough to directly risk the health and safety of humans through inhalation.
You know, I mistakenly conflate CO2 and particulate matter — I recognize my error.
We aren’t even halfway to the “this isn’t a great idea to live in” levels, and far from lethal levels. Purely from a “toxicity” level your bedroom at night is far worse than projected co2 levels in the next 100 years.
Does that mean it’s fine to keep increasing? No. But arguing that we are anywhere near “high levels” as it pertains to toxicity is inherently flawed.
