CO2 overload in blood suggests toxic atmosphere within 50 years

I'm a bit confused by this, since indoor CO2's higher (double?) so wouldn't we already be experiencing it?

The study doesn't say "fatal" it says "toxic". Not toxic like lead, toxic like cigarettes. The actual effects discussed are subtler than "all life dies in 50 years".

Dang can we please change this editorialized title? When you click through the actual title is: Carbon dioxide overload, detected in human blood, suggests a potentially toxic atmosphere within 50 years

Won't the rising, boiling oceans get us before we have to worry about this?

> There is mounting experimental evidence that lifetime exposure to these increasing atmospheric CO2 levels can negatively impact the normal physiology of organisms... Studies indicate that, after this time, elevated atmospheric carbon dioxide, leading to CO2 accumulation in the body, has the potential to cause a range of adverse health effects. There's an awful lot of distance from "can" and "potential" to "toxic".

So even will all the effort we've put into solar and decreasing coal, being more economical unless there is massive widespread international cooperation to suddenly and rapidly start deindustrializatizing the air we breathe will be doing us in less than 25 years. Sounds great, at this point doesn't really seem to be anything I can do as an individual except enjoy the ride, because it's now a race to see whether swarms of killer AI robots do us in, the global economy collapses, the ocean currents fail, and if none of those happen the air will end up killing us all anyway. Sounds like I might as well try and enjoy it while it lasts. Cheers!

co2 by itself doesn't appear to really matter: https://news.ycombinator.com/item?id=19863319 key phrase being "There's a big difference between seeing high concentrations of carbon dioxide as indicative of poor ventilation and seeing high concentrations of carbon dioxide itself as detrimental to cognitive function."
