This is not what I needed to start my Saturday morning with

Given that the entire evolution period for humans has seen a stable and relatively low atmospheric CO2 level (< 300 ppm), it’s possible that our physiology is finely tuned for a range of CO2 that will not be much greater than this level. As the atmospheric CO2 levels rise, already at 420 ppm, the increasing levels of bicarbonate, and decreasing levels of calcium and phosphorus in our blood represent permanent and growing changes in human blood chemistry. These changes can be explained by CO2 retention and overload in the body. The extra CO2 being inhaled isn’t expelled via increased ventilation, as ventilation rate is controlled by pH which has likely remained stable due to acid-base regulation. CO2 storage in the body then becomes a major issue presenting a risk to population health and an existential threat for many species especially given that the rise in atmospheric CO2 may be a phenomenon that has significant momentum. Realistically, to mitigate this approaching threat, the alarm needs to be raised immediately. Unfortunately, currently there is little awareness or inclination for action on this issue.

Now, now, I've been assured that CO2 is not a pollutant

Brother I am so ready to be melted from inside out by my blood fuvk this shit

"Well, I guess it's time to wrap up this experiment called human beings up. It was a good run."

"Climate change will likely wipe out most of what we recognize as life..."

"...well, I guess its time to wrap up all of life then... please hug me."

"No."

Ha! Joke's on you, scientists! I'll be dead by then!

We're here as stewards to this planet and all of her life. We've failed at it all in our quest for money, power, and greed. I for one don't feel bad for us one bit. I do feel bad so many innocents will have to suffer, but we did nothing to stop this and it's what we deserve.

i thought we needed to be closer to 800- 1000 pom for this to be a significant problem but that might have been me confusing studies on cognition with this ?

it would be nice if it sent us sterile.

This great news! Not just not have we an increasingly unstable climate causing unprecedented heatwaves, droughts, floods, snow, now we have steady increases atmospheric CO2 will cause direct health impacts and if it goes on then we will need to mutate to cope with it. That they can measure the increase in atmospheric CO2, by proxy, in the blood is pretty frightening.

You can see the change here:

They do mention that CO2 levels are typically higher indoors and that Americans spend 87% of their time indoors, but it would have been interesting to see a prediction for how much sooner this would become a problem inside.

Ironic that the climate change deniers were usually the ones that claimed (falsely) that wearing masks caused this

On a related note, it turns out that CO2 emissions also impair cognition. So, by the time the crisis peaks everybody is going to be too cognitively impaired to actually do anything about it.

Well fuck.

Effects of indoor plants on CO2 concentration, indoor air temperature and relative humidity in office buildings

We examined the impact of indoor plants on air quality parameters in office environments, focusing on relative humidity, indoor air temperature, and CO2 concentration. Our findings demonstrated that, while indoor plants significantly increase relative humidity, they had a negligible effect on indoor air temperature and CO2 concentration in the offices we sampled. This suggests that while plants can enhance comfort in dry indoor environments, their role in regulating temperature and CO2 levels is limited.

I guess I’d need to invest in a CO2 scrubber.

Oh well, my retirement plan was dying anyway.

Well we couldn't stop capitalism from killing us and now it's killing us.

Maybe what comes after has a chance to not invent a species killing ideology.

Damn. Our current trajectory already would've made life very difficult in 100 years, this news moves up the potential extinction part to be far closer than I'd anticipated, which means if we can't cast off capitalism soon, it will destroy our species and most other life on earth very rapidly.

We desperately need to build up decentralized grassroots working class movements globally as quickly as possible, enabling the use of our most powerful weapon: the General Strike.

The governments propping up fossil fuels would be brought to their knees if suddenly deprived of profit and labor, allowing us to demand real changes, such as an end of fossil fuels, the abolishment of centralized state governments, and the end of capitalism.

The general strike was extremely effective in Chile in 2019, and had they not fallen for the trick of liberal reform, they would've had a successful revolution on their hands.

There are some concrete steps all of us can take toward enacting a general strike to make it more viable and bearable for us all. (the titles below expand if you click them).

I'd also highly recommend Full Spectrum Resistance to anyone who wants further info on how to resist (audiobook version here).

I took a quick skim. By toxic atmosphere, they mean as in probable health hazard, not as in directly killing people immediately.

Indoor co2 levels can easily hit 1000+ ppm co2, especially if your dwelling is well sealed, as many energy efficient dwellings are. Submarines keep co2 at the thousands ppm for extended periods and were the impetus for co2 studies on how much humans can take.

I don't think a major concern of rising atmospheric co2 is the direct threat to health caused by elevated co2 levels. I, personally, would be angered if someone told me that high co2 levels were dangerous to human health and then I read this.

So maybe in 100years of you can pay for it you can buy your home O²enrichment

Thank god we still have mars

Finally corporations will be able to start selling subscriptions for air to breathe! A bright future for shareholders the world over.

But Mark Carney wants anotha pipeline!

Start evolving people!

To quote the actual abstract, not just the headline,

There is mounting experimental evidence that lifetime exposure to these increasing atmospheric CO2 levels can negatively impact the normal physiology of organisms. However, directly assessing this in humans is very difficult.

It does not say that they for sure know that atmospheric CO2 levels are going to be toxic within 50 years. It only says that, based on one examination of indirect proxies, it seems like that might be the case. Something which definitely should be studied further, because even the possibility of global atmospheric toxicity is worrying, but not something to jump to conclusions on, because doing so is bad science.

Their study result makes me feel kind of sick to my stomach too, I just want to keep a level head and not jump to "welp I guess we'll all be paying billionaires for clean oxygen tanks in 50 years".

If this really does turn out to be a problem we're heading towards, it's also premature to conclude that it won't get fixed. I know that if I learn that this is for real, I'm certainly going to be telling everyone I know about it and looking for ways to spur useful action.

Couldn't have happened to a more deserving species. Shame about all of the others that are dying with us.

Neat.

"it’s possible that our physiology is finely tuned for a range of CO2 that will not be much greater than this level.". Also possible we will adapt or have to wear masks. Or will all die out.. or a giant dinosaur 🦖 happens because of radiation ...or nukes... Aliens.... Jesus returns...

I don't like this, but not surprised. We keep smoking (polluting) and we keep cutting away our lungs (removing nature).

Yeah. If you have kids after today, you’re a selfish cunt.
