The one-eyed science monster is here again to scare teenage girlies
No one is funded to poke holes in the CO2-octopus, so researchers can follow a silly idea for a long time. In a normal world someone would have scoffed and squashed this horror show in the tea room.
It is yet another meaningless correlation pretending to be a dangerous trend. Supposedly rising levels of carbon dioxide in the air around us is tainting our very blood, causing a public health crisis. Atmospheric CO2 is “higher than anything humans ever experienced” says Dr Phil Bierwirth, worried that current CO2 levels are beyond what we evolved to deal with, and 100% wrong.
Poor Dr Bierworth obviously doesn’t realize that even though atmospheric CO2 has risen from 320ppm to 420ppm, normal indoor CO2 levels are 500 to 1,000 ppm, and the air we breathe out is 40,000ppm.
We don’t need a quarter century to raise our blood CO2 levels — we can hold our breath and get there in sixty seconds.
Or we just need to go jogging.
Since he is a retired environmental geoscientist, it was cruel to set him up to fail so badly on what is a beginner medical question.

Rising carbon dioxide levels now detected in human blood
— Phys Org
Rising carbon dioxide levels are being detected within the human body, with new research warning a key blood marker for the gas could near its healthy limit within decades if current trends continue. The findings are especially relevant for children and adolescents, whose developing bodies will experience the longest cumulative exposure to rising atmospheric CO₂.
Using data from the U.S. National Health and Nutrition Examination Survey (NHANES), the team examined blood results from around 7,000 people every two years between 1999 and 2020.
Average levels of serum bicarbonate—a marker closely linked to carbon dioxide in the body—have risen by approximately 7% since 1999. Over the same period, average calcium and phosphorus levels have declined.
So many travesties of correlation in modern science use the term “mirror”:
These changes mirror the rise in atmospheric CO₂, which has increased from about 369 parts per million (ppm) in 2000 to more than 420 ppm today.
Humans evolved in an atmosphere containing roughly 280–300 ppm of CO₂. The average annual increase over the past decade has been about 2.6 ppm per year, with 2024 recording a 3.5 ppm rise.
“It appears we are adapted to a range of CO2 in the air that may now have been surpassed.
“As CO2 in the air is now higher than humans have ever experienced, it appears to be building up in our bodies. Maybe we can never adapt such that it is vitally important to limit atmospheric levels of CO2.”
We not only evolved to deal with high levels of CO2, it is an important signaling mechanism in our blood — high CO2 levels tell red blood cells to give up their oxygen. It’s how our blood gets oxygen to the cells that need it the most.
Whole health movements have been built upon raising the CO2 levels in our blood — like the Buteyko breathing or the Alexander technique — both used to reduce asthma.
If bicarbonate levels are slowly rising in blood perhaps it might be because there is more time spend indoors, less sunlight, poor breathing techniques, poor fitness levels, or more people with sleep apnea?
The obsession with energy efficiency means air flow indoors is more restricted than ever and thus we probably sleep in rooms with higher levels of CO2 than we did 30 years ago.
Whatever it is, modern witchdoctors will try to reduce blood bicarbonate levels with windmills.
UPDATE: CO2 dissolves in blood with the equilibrium reaction:
CO2 + H2O ⇄ H2CO3 ⇄ HCO3– + H+
If you hyper or hypoventilate for a few minutes it is possible to shift the direction of the flow here and even change blood pH. The pace of breathing, and the shallowness or depth will change the bicarbonate levels (HCO3-).
Check out the title of the paper! A ‘potentially toxic atmosphere within 50 years!’ It could only be written by zealots living in a crazy bubble.
As Dr Faustus remarks below, most of the CO2 in our blood is created by our metabolisms as we burn fats and sugars. A small rise in the air around us is irrelevant.

Having worked in a Physiology dept it was my understanding that the breathing reflex is triggered by co2 concentration not o2 levels.
Grok agrees – ‘The involuntary (automatic) urge to breathe and the primary drive for normal breathing rhythm are triggered mainly by rising CO2 levels (or more precisely, the resulting increase in blood acidity, or drop in pH) rather than falling O2 levels.’

This sounds like it might be Babylon Bee satire but since the Left have become parodies of themselves, we know it’s not.
It’s so tough for satirists these days, or even to establish whether the latest insanity of the Left is real or satire.

It is April the First everyday now. I wonder just how much mankind is wasting on the sort of drivel these people have produced and what could be achieved spending the money on something of benefit although it is questionable as to whether those involved in this could produce something of merit.
60
The only thing REALLY rising is the funding for junk science like this latest serving of dreck
220
The level of desperation is also rising, Pauly, as is the level of crap.
90
At least I’m glad none of my taxes paid for this Australian “research”, at least I hope not. But presumably it still cost the time of taxpayer-funded “researchers” who should have been doing something useful instead.
120
260
Phys Org – or whatever the letter head says is another ‘Conversation’ type site. Is it publicly funded?
20
Notice how the CO2 scare stories keep getting more extreme and more bizarre?
260
Directly related to desperation as the gravy train recedes into the distance taking their cushy funding with it. Horror of horrors these charlatans might have to find work more suited to their inabilities.
90
Just keep an eye on the weather forecasts. Forecasts of “ extreme “ weather, “ severe “ storms etc are almost daily stories. Last forecast for our area predicted severe storms & possible flooding ( same as 5 or 6 previous forecasts ). As usual we had less than 10mm of precipitation over the following 24 hours. Maybe the relief could be attributed to a neighbour about 5 houses further down the road buying an EV. 😂😂😂. That’s the message they’re trying to send. Poor ole BoB!!!
90
I wonder what the submariners think of this.
“The average CO2 concentration on U.S. Navy submarines is reported to be around 3,500 ppm, with a range of 300 to 11,300 ppm. Studies suggest that exposure levels up to 40,000 ppm do not significantly impair cognitive performance in submariners.” So says the web.
400
Nuclear submarines can apparently remained submerged with purified air to breath and desalinated water on board for very long periods and do not of course need refuelling and air supply reasons to surface and become vulnerable to surveillance and attack.
They are also very fast underwater as compared to convention diesel-electric propulsion submarines. A US Aircraft Carrier visiting Sydney 1990s told a visitor flown out to experience ship life before it entered into Sydney Harbour said the Captain was not willing to tell him the top speed on that ship and battle group accompanying it, but did admit when reminded that Jane’s Fighting Ships magazine had exposed it that the nuclear submarine below the fleet can zig zag and keep up.
The guess is that the Aircraft Carrier could at full speed ahead exceed 30 knots.
90
If the figures quoted are real and they are statistically significant, they still represent very small changes, just a few percent. It’s also possible that any change over the study period 1999-2020 is also due to people spending much more time indoors, a high CO2 environment, than they did in previous times.
210
The use of face masks and curfews that our polititions forced upon us, would account for that CO2 David.
180
If you were to correct the figures for the increased time spent indoors – maybe using a technique like homogenisation – you would find that CO2 levels in human blood are decreasing at a frightening rate. So you have two choices: 1. CO2 levels in blood are rising at a frightening rate. 2. CO2 levels in blood are decreasing at a frightening rate. There is no option 3 because it isn’t frightening.
200
Improved insulation in houses to improve energy efficiency (and limit the rise in energy prices caused by other “green” policies) is another likely cause ion the increase in CO2 levels in human blood, at least in some countries.
10
Why was a geoscientist employed to write an article about a change in CO2 concentration in humans? Why was it not a physician? A physiologist? A human biologist? Or anyone in a discipline actually dealing with the body? This is like appointing Tim Flannery to be the climate change spokesperson; an anthropologist, completely untrained in the requisite scientific discipline. That’s the clue.
250
Anyone who supports the Official Narrative on “climate change” is considered an “expert”, even ignorant and stupid politicians who are allowed to make multi-billion dollar engineering decisions.

Hence, Jo posting that image of Edvard Munch”s iconic painting “The Scream” is so appropriate. Known by the Norwegians as “Skrik”, the image typically is interpreted as a depiction of existential human angst. A 134 years after it was painted, we can present it as a symbol for all the hysteria and anxiety that the climate alarmists supposedly suffer from.
50
More laughable lunacy for us to ignore and as stated above Submariners live for weeks or months with co2 levels at many thousands of ppm, so I’m sure we can easily cope with 425 ppm.
Anyway in a normal conference hall co2 levels can easily be 600 ppm + and yet our life expectancy in the wealthiest countries continues to increase. Just look up the data.
210
Yes, but alarmists have seen them turn blue in the face haven’t they?
No? Ok. As you were.

Hilarious! Your point is extremely sharp, Jo. I cannot stop laughing.
151
Not so funny David. I have noticed that my fingernails and toenails are growing faster as CO2 concentrations increase.

A decade ago I floated Sherrington’s hypothesis that the size of human teeth was increasing in correlation with higher ambient CO2 concentrations in the air.
Are any dentists reading this? Comments? Geoff S

The Buteyko method of breathing to control Asthma results in the beneficial increase in CO2 in the system.
Jo,
Perhaps you could tell us more about that?
40
Sorry, Jo. In reading your post in more detail I see you have already made this point.
I’m just a poor old dumb civil engineer, but on one of my projects I got tangled up in the construction of a 200 seat lecture theatre. I found it interesting that the air-con boys had designed their system to monitor CO2 levels and to divert fresh air into the re-cycling mix to keep the CO2 level below a point that causes drowsiness. (I don’t recall what that level was.)
I’ve also wondered whether it’s rising CO2 levels at church that causes yawning and sleeping or the boring sermons!
160
MichaelinBrisbane,
Thus negating the one benefit many such lectures have.
120
Where were these studies when mask wearing was causing CO2 intakes to soar? Or maybe this is a COVID after-effect!
110
I had a blood test recently, no mention of CO2, have I missed something.
120
CO2 wasn’t even mentioned in any of my tests in the last 30 years… Perhaps they didn’t find any and didn’t bother to tell me. Should I sue them for malpractice?
20
For the last 300,000 years Human life expectancy was about 28.5 years, but today Human life expectancy is about 74 years.
IOW as co2 levels have increased since 1800 or since the start of the Industrial Revolution life expectancy has soared plus GDP per capita. See OWI Data.
Of course Human population has increased by a further 7.2 billion in just the last 225 years as well.
So why can’t they spend 5 minutes online and then wake up to their silly nonsense?
80
I understand that in Australia it is now 80 years and increasingly people are living beyond 90 years and record high achieving 100 plus.
20
Dennis, Australia is now 84.18 years. Scroll down to see all countries at the Macrotrends link.
BTW the global life expectancy has been reduced recently to under 74 years, evidently because of covid deaths.

Checking my tests, bicarbonate is usually in range, but it seems highly volatile. One time it went from 30 to 22 in tests 8 weeks apart, which is marginally above to the bottom of the normal range. There was no obvious reason.
Something that is so easily influenced by diet and exercise surely can’t be a reliable basis for such a study.
10
Mr Grim, volatile is the word. If you hyper or hypoventilate for a few minutes it is possible to change blood pH. The pace of breathing, and the shallowness or depth will change the bicarbonate levels (HCO3-). It is an equilibrium reaction.
CO2 + H2O ⇄ H2CO3 ⇄ HCO3- + H+

Daft comment.

“Humans evolved in an atmosphere containing roughly 280–300 ppm of CO₂”
I doubt it. Firstly we share a lot of DNA with lobsters. And lobsters react similarly to seratonin. So I think he is talking about evolution as humans moved from the ocean to the land from a time when CO2 was very much higher and plants reduced CO2.
Plus like everything else, such a person believes everything is just perfect today and evolution, plate movement, planet nutation and climate variation and sea level variation should just stop. This can all be acheived with windmills and solar panels.
170
I wonder what he thinks of people who have already adapted to lower O2 levels?
“High-Altitude Natives (Tibetans/Andeans): These populations exhibit superior adaptations, including larger lung capacities, higher resting ventilation, and in the case of Tibetans, a lower hemoglobin concentration that protects against mountain sickness.”
So as with sea level rise, the logic here is that we should use the power of science to stop any changes. Because we are perfect. And the weather is perfect. And the sea level is perfect. And CO2 levels were perfect in 1750. So change should be illegal.
160
OMFG- you have totally lost it. Please pick up a genetics or biochemistry text.
014
Perhaps you should take your own advice for once?
“Humans and carrots share roughly 98.7% of their DNA, based on comparisons of conserved genes, highlighting that basic cellular processes (DNA repair, metabolism, translation) are remarkably similar across life forms. Despite this, carrots have a larger genome, with about 32,000 genes compared to roughly 19,000–20,000 in humans. “
110
and?
The housekeeping genes that all eukaryote cells have are highly conserved across all taxa. What has this to do with dissolved CO2?
19
I picked a very different and delicious animal with a common ancestor which lives life in a very different CO2 environment under the water, but breathes out CO2, as all living things do. It’s specist to demand a certain level of CO2 in the air for humans, the CO2 of 1750AD at sea level.
Everything adapts. Darwinian selection, adaptation. It’s particularly churlish of any scientist to claim they are the highest lifeform on earth and imply they perfect in every way and want evolution to stop. And sea level changes to stop. Even a variation in average CO2 levels has to stop. It’s all quite absurd.
80
I’m a PhD in genetics. I maybe have picked a book up at some point apart from the one I wrote.
19
Then you should have known better! Are you playing games? I studied genetics and biochemistry as well. Biophysics too. But my interests were elsewhere.
100
Then why write about housekeeping genes in lobsters when discussing whole body responses to CO2 in humans? Bonkers if you think that you had a point.
07
A PhD should be able to work it out. It’s not rocket surgery.
60
parsimony plus the nonsense you wrote above tells me that you don’t have a clue.
03
OMFG (to repeat your words) respiration genes evolved 2.4 Billion years ago, and thus some of the oldest genes. They evolved through the monster CO2 era (when CO2 levels were 4000ppm+) and spread to, well, every animal that breathes.
TdeF is correct, and you know it, (you said as much “The housekeeping genes that all eukaryote cells have are highly conserved across all taxa. “) His point was only that this is a very small-minded fixation by these researchers on the last million years. Amphibians crawled out of the ocean 370 million years ago. So air breathers have dealt with higher CO2 levels for most of time since then.
Just because the human species did the final evolutionary tweaks in the last million years doesn’t mean we lost the ability to breathe air at 425ppm. Even cavemen had to deal with higher CO2 as they slept huddled together in their caves or stick-huts surrounded by animal skins, especially if they had any fires burning. If the weather was cold, you know, they probably restricted the airflow as much as possible. Hence the fact that humans *evolved during an ice age* suggests we would have to cope every night with higher CO2 in enclosed spaces.
As Dr Faustus mentions below, most CO2 in our blood comes from our own respiration — burning fats and sugars, not from what we breathe in.
What evidence do you have that humans developed some novel fragile super-tuned respiration pathways that would affect us even if the global atmosphere returned to 500ppm or 600ppm?
120
Sorry but what? Do you know about genetic background? Homeostasis? About the vast differences in physiology? No, you and Tdef are very wrong. The fallacy about us sharing genes and a common ancestor means we are the same for a chosen trait is an old and boring one, and not too far removed from creationism in its disingenuousness.
As for where the CO2 comes from. Again, so what? At the blood air boundary, CO2 is exchanged in the lungs at a rate proportional to the [CO2] in the lungs. If you change that equilibrium to reduce loss from the blood you get a higher [CO2] in the blood. That is also not rocket science. Members of this blog have a hard time understanding equilibria in atmospheric science so it’s understandable that they struggle here too.
010

In other words, you have a qualification in a field that thinks it knows everything, but actually knows bugger all (like climate science). Come back when genetics has actually grown up into a mature science rather than a bunch of wannabes that haven’t even scratched the surface.

Quickly reading their paper, it seems the authors are working under the impression that the entire presence of serum bicarbonate is due to atmospheric CO2 entering the body through respiration and dissolving in the blood. Their ‘model’ then is a simple one: increase in ambient CO2 = proportionately greater uptake – a measured linear relationship implies correlation, so QED.
https://link.springer.com/content/pdf/10.1007/s11869-026-01918-5.pdf
In fact, serum bicarbonate is created in the body by the energy-producing reaction between oxygen and glucose, which produces the bicarbonate ion as a waste product. Dissolved CO2 introduced via respiration makes up such a small proportion – 5% – that it is not measured separately in blood testing and is reported along with bicarbonate.
https://www.ncbi.nlm.nih.gov/books/NBK308/#:~:text=We%20measure%20serum%20total%20CO,30%20mEq/L%20of%20serum.
The problem then for the disasteratiiis explaining why the minor antmospheric contribution apparently achieves 100% of the claimed biological change.
Which our authors don’t seem to notice.
210
Possibly the point is that CO2 is toxic pollution per se, ipso facto. So any level of CO2 is bad. And a higher level of CO2 is far worse. Who cares that human beings are internal combustion engines burning sugars into CO2 and H2O. In a perfect world we would run directly on solar energy for body warmth and muscular energy. Perhaps closer to Lizards and snakes then. A bit like solar panels in Norway in Winter.
190
thanks for the link and great to see someone on here actually reading the paper.
perhaps Jo would address her criticisms to the paper, which is about sustained (24/7/365) breathing of air at >400ppm CO2 vs the long term average of <300ppm. It is not about our ability to cope with short term – minutes, hours – high levels of CO2.
It is about the knock on physiological affects such as caused by changes in the blood and bone calcium concentrations.
All comments here critiquing the paper that don't know what the paper is about are off the mark.
117
Gee Aye, given that many people are now almost entirely indoor creatures, they are breathing CO2 levels of 600 – 1000 ppm. How do we detect the outdoor rise to 425ppm when the overwhelming force in this experiment is indoor CO2?
Every single night humans are sleeping in a high CO2 environment, and that’s been the same for centuries.
If anything, the obsession with energy efficiency may have increased CO2 indoors as drafts and airflow are reduced.
190
Every single night humans are sleeping in a high CO2 environment, and that’s been the same for centuries.
Combined with the new building requirements relating to air transfer, this is why the ceiling fan normally is running in our bedroom all night.
60
Indeed. Thus contributing to Sick Building Syndrome (SBS) and also seemingly increased cases of mould. On top of that, the sort of people who even today wear masks while alone in their cars, probably are also too paranoid to open their windows, or even go outside unless absolutely necessary, thus breathing in huge concentrations of CO2.
Back in the day, Australian houses were extremely well ventilated, perhaps not energy efficient but they didn’t have to be, Australia was blessed with cheap energy before John Howard made it expensive.
80
I’d be interested to know what the actual average and minimum is. Haven’t dug up a study yet.
On the subject of that study, done not so far from you, is that it is mostly over-reach.
Conjecture and what-ifs are fine in publications in context and in proportion to the data, but this paper extends itself beyond what is reasonable, especially given the preliminary nature of the primary data.
I think there is something worth investigating even if it comes to nothing.
I don’t know but that doesn’t mean it can’t be. It would be fallacious to use that as a proposition to dismiss any further study.
06
I habitually keep my small kitchen window open about 3 inches and daily hold the front door open for a few minutes early and late in the day to freshen the air and increase O2 levels.
I never like a closed-up house which is why there is no door stripping at the bottom of the front door.
I also have over 20 houseplants available to suck up some of the excess CO2, Cyclamens, Cape Primroses, Christmas Catus, African Violet, Moth Orchids and a struggling Gardenia.
I use my green thumb a lot.
20
Sounds like a great plan, and especially admirable in the cold weather I know you get sometimes…
10
When it gets cold I have the window open a crack overnight, open it up a bit in the afternoon, it was 66 degrees F today (19 C) that makes the window open by 15cm soon will close it back down.

So have fossil fuels saved us from the “150 ppm line of death for plants” during the next full glaciation?
So why wouldn’t we want to save our planet from co2 starvation if we can all benefit as well?
Here’s the quote from the co2 Coalition Scientists’ facts archive……
“For the last 140 million years, CO2 levels fell precipitously & steadily to within about 30 ppm of the 150 ppm “line of death” below which plants can’t survive. Both the relatively short-term data from ice cores and much longer-term data going back 140 million years (Berner 2001) show an alarming downward trend toward CO2 starvation. The release of carbon dioxide by the use of fossil fuels has allowed humanity to increase concentrations of this beneficial molecule, and perhaps avert an actual CO2-related climate apocalypse”.
60
Yes, that’s why I have thought for a long time that CO2 levels at about 1,000ppm would be preferable.
40
What a breath of fresh air
40
Never knew CO2 could be so much fun!
20
Complex life began about 600 million years ago and today our current quaternary period has the lowest co2 levels for the last 600 million years.
So what are we worried about and shouldn’t we all want a much greener earth?
Here’s the quote from the co2 Coalition Scientists…..
“Contrary to the oft-repeated mantra that today’s CO2 concentration is unprecedentedly high, our current geologic period, the Quaternary, has seen the lowest average levels of carbon dioxide since the Precambrian. Though CO2 concentrations briefly peaked 320,000 years ago at 300 ppm, the average for the past 800,000 years was 230 ppm (Luthi 2008). The average CO2 concentration in the preceding 600 million years was more than 2,600 ppm, nearly seven times our current amount and 2.5 times the worst case predicted by the IPCC for 2100. Our current geologic period (Quaternary) has the lowest average CO2 concentration in more than 600 million years”.
30
This is the beginning of the evidence that shows a direct link between increasing atmospheric carbon dioxide and human life rather than just a climate link now that the climate link has been exposed as a scam.
Opening windows would be an easy fix to lower CO2 levels. Also take a walk outside.
My CO2 meter sees an increase when I face it as opposed to looking away from it. It inevitably has a lower reading outside than inside.
A bigger house would be expensive but also a way to lower CO2 levels.
30
Rick how much did your co2 meter cost and what brand is it?
10
Pointing out that people living indoors experience higher levels of CO2 to those living in the fields and caves would not be unexpected, even if the atmospheric CO2 levels were constant. Especially with the move to high rise city living worldwide. 83% of Victorians now live in Melbourne increasingly not in a free standing home. Nothing to do with Climate Change, but the whole study is just grant milking, not real science. I suppose they could study the methane content of farts too.
60
Don’t give them any ideas! Our taxes will be further wasted.
60
Less calcium in the blood increases acidity, so the bicarbonate buffering system produces more CO2. It is especially the case in people with infection whose bodies are struggling to regulate ph, and with the the average microbiome continuing to decline the average person is more acidic than in 1999.
40
Somebody played a real practical joke on this idiot. Come in sucker.
10
Oh dear, so at 420 ppm we are close to the limit of what humans can cope with? Someone should take him aside and quietly point out that the air in submarines especially nuclear submarines which remain submerged for long times is controlled to around 2000 to 5000 ppm and humans have no problem at all coping with that for months on end. So 420 ppm is nowhere near any significant limit.
60
Oh dear. One of the bots has made it through the new security settings.
GI don’t know how to fix the problem. Then again the problem only appears during business hours.

So we are worried that CO2 in the atmosphere has climbed from 0.028% to 0.042% in 250 years. Life threatening.
It means we now breathe in CO2 at 0.042%. And we breathe OUT at a massive 7%. Worse, exercising hard at 14%. Over 330x as much CO2!
And we are supposed to think the amount of CO2 incoming matters. It hardly matters how much CO2 is in the air!
It matters to plants. They are built from CO2 entirely. More CO2 means more trees and trees growing faster. NASA have proven this.
But humans are built from real food, carbohydrates we can burn into CO2 and H2O. Incoming CO2 is likely so low as to be insignificant for humans, except that CO2 buildup is used to trigger breath taking, likely as a developed defence mechanism.
It is unlikely that an additional 0.0144% CO2 in the air matters in the slightest. (At sea level, in the open with no face covering)

I don’t suppose the small increase in these CO2 levels could possibly be attributed to the fact that people are spending more time indoors and less out in the fresh air?

They probably sampled a group who had been out drinking the previopus night. LOL

Bierworth is a chook! He’s trying to make a bogeyman out of natural processes. These results prove that the laws of chemical equilibrium are working as they should.
