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 swarm…

A nuclear build out would make enough cheap electricity to scrub the atmosphere clean.

> 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".

A sign of intelligence is to prevent "can/maybe/potentially" from becoming "actual", especially when the consequences are dire. A sign of unintelligence is to ignore the signs, then blame the ones who acted for needlessly averting the tragedy, claiming it would never have happened.

Wow, you competely edited your comment to say something different than the one I replied to.

You also still failed to articulate your argument.

I don't think you want to make this about intelligence.

ironically, the collapse of the global economy is what could save us

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

You can get a decent CO2 meter from stores like IKEA. You’ll come to the conclusion that the cozy feeling you get sometimes is directly related to the ppm being well over 1000. It affects your thinking, but it creates “atmosphere”. The first 440 ppm you’ll get for free. This used to be lower and has risen steeply in the last 100 years and continues to do so. See the historical graph at https://www.co2levels.org/

For homeowners, I highly recommend making sure you have some way to bring it fresh air on demand, and then automate it in conjunction with a CO2 monitor. I added a duct fan and ERV before my HVAC system's fresh air intake, and then tied the fan to an air quality monitor.

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

The study points out that CO2 levels are rising, and in 50 years might cause blood HCO3- to exceed 30mEq/L. It then references https://journals.lww.com/cjasn/abstract/10.2215/cjn.11941017... as to why that level is dangerous. But if you read that abstract, it's about diagnosing blood diseases, and suggests based on surveys of different studies of current people's blood levels that levels above 30mEq/L be flagged as o…

High bicarbonate in blood is not a blood disease, in the same way that high glucose in blood is not a blood disease either. High bicarbonate leads to severe and serious problems that can be fatal in those with weak lungs or a weak heart and in children and the elderly. Even in healthy persons, high bicarbonate will lead to low extracellular potassium which is immediately detrimental to the heart. I have experienced it first hand. There is a reason why bicarbonate in blood has a reference range.

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

No. Even with the amount of co2 current being dumped into the atmosphere there's not enough total solar energy capture to Venus things up. A few thousand years, absolutely. To add: desertification and more or less removing the support systems for modern population levels can easily happen with what's going on. But the oceans won't boil first. Everything else will die first.

Why are you only talking about co2 if you're going to try and be serious when responding to a joke? Please make an attempt to understand the situation better if you care that much.
