Or: Surging levels of greenhouses gases are making people tired and stupid, scientists claim
- Higher CO2 in poorly ventilated places can make workers feel tired and slow
- Entire population could experience tiredness caused by burning of fossil fuels
- Huge surge in levels of CO2 in the air could affect memory and concentration
Surging levels of greenhouse gases could make people tired, forgetful and stupid, scientists claim.
Afternoon fatigue, the slump that office workers often experience, could become a worldwide problem due to surging levels in carbon dioxide.
A factor in sick building syndrome is higher carbon dioxide levels in poorly ventilated workplaces which can make workers feel lethargic, low in energy and slow, The Sunday Times reported.
But increased levels of carbon dioxide could not just affect office workers but the entire population by the end of the century, according to scientists at University College London.

It is the first research by scientists to warn about the toxic effect that raised greenhouses gases can have on humans.
The raised levels of carbon dioxide would be driven by the burning of fossil fuels.
Burning oil, coal, and natural gas are the leading causes of the carbon dioxide emissions driving climate change.
‘Human cognitive performance declines with an increase in CO2’, the researchers wrote in the paper.
‘Direct impacts of CO2 emissions on human cognitive performance may be unavoidable’.

I’ve wondered why there are so many stupid people around. I thought it was the school system.
You are on to something there Karabar and CAGWarmistism has a lot to do with it in that CO2 phobia is at epidemic proportions.
Indirectly it is, Sophie is a graduate of ‘journalism’ school, and she’s clearly intent on making people dumber than prior to reading her insights, so there’s an indirect link there, and if we dug a bit deeper we could probably convert that to a direct link to the school she came through.
Could someone help me with the logic here? I breathe in 0.04% CO2 and I breath out 4% CO2, so I’m already exposed to a CO2 concentration 100 times that of the atmosphere. The CO2 concentration in the air of a nuclear sub ranges from 3.5% to as high as 10.6%. How do these sailors know which way is up? Even if you double ambient CO2 levels to 0.08% what possible effect could that have?
Trebla;
I think you have added a “0” to the magnitudes in submarines. A quick search yields 3,500 – 10,000 ppm, which would be 0.35% to 1%. 10% would be 100,000 ppm and is a level considered “immediately dangerous to life and health” by the Center for Disease Control.
As long as the O2 percentage is high enough – does it matter what the other gasses are? I have been in labs where CO2 and N2 are used for cooling tests. They have to have an O2 monitor installed. Of the O2 goes too low an alarm goes off so everyone doesnt faint and die.
“does it matter what the other gasses are?”
Yes.
By the way, the alarm for low O2 is needed because our breathing reflex is keyed to the amount of CO2 in our lungs, not the amount of O2. If e. g. N2 increases and replaces O2 we just “fall asleep”, for good.
On the other hand if CO2 goes too high we will definitely notice it, even if there is enough O2 around.
It is the school system.
yep
I’m guessing a healthy autocorrelation with liberalism might be in play. Yes, on the submarine we had a somewhat larger concentration of CO2, but I don’t think there any extra stupidity was exhibited. It’s not the best environment for it.
Well it is absolutely clear that it is making the climate scientists more stupid
Yeah right – how about lack of oxygen?
My first thought as well Karabar. We can restate that headline to read: “Surging levels of propaganda are making people tired and stupid. Public Schools attendance thought to be the leading cause.”
I wonder if private schools are perhaps more liberal leaning than public schools? This constant beating of the drum against public schools without a shred of fact gnaws on my nerves. Yuppies who homeschool and private schools that cater to the young family already born with a silver spoon may be just as gullible to poor research and overly stated conclusions, such as the one in this sub thread.
” This constant beating of the drum against public schools without a shred of fact”
Yikes!
Item 1:
Around 1990, I noticed a huge shift, and all at once. All of a sudden, the young clerks at the convenience stores could not make change for a purchase. They had to wait for the automatic cash register to calculate the amount of change to return to the customer.
I have to tell you, this was not one incident, it was widespread. The current generation has no clue about counting up change. They just do not know.
Item 2:
I noticed a co-worker struggling with filling out the repair tickets for the work we were doing. Literacy, obviously was the problem. So I quizzed the fellow.
Vowels, consonants? Nope.
Dipthongs, breaking a word into syllables? Never heard of it.
Ok, how did they teach you reading? “We were told to recognize words by their shape“.
Clearly, the next level up, nouns, verbs, adjectives, and the whole structure of the language is totally inaccessible to this fellow. A true functional illiterate, increasingly common today but unheard of 20 years prior.
Item 3:
The National Geographic Society sponsors the annual National Geographic Challenge, an academic competition for school kids.
Circa mid 1990s, they give up after a majority of high schoolers could not identify Canada and Mexico as the neighbors of the US. to the North and South.
Item 4:
I have been informed that the recent crops of P.S. graduates can not make use of a standard round faced, analog clock. Without a digital clock, they literally can not tell the time.
The proof is all around you, walking around town, shopping in the malls.
They can not count change or tell time. They are functionally illiterate and profoundly innumerate. They can not find Europe on a globe.
But they can, and will, tell you how they feel about everything.
One must remember that the state sets the minimum requirement standards for both public and private systems. Most home schooler’s have to abide by state approved plans and testing. (At least we did. We had to obtain approval for our lesson plans and testing).
As home schoolers we choose to go beyond their standards and include cognitive thinking exercises and reasoning skills. I would hope that is what most would do. We did and many friends we have, that home school, also go the extra mile in the hopes we will not raise sheep. Its rather interesting that the state frowns on adding these to their curriculum. We fought tooth and nail to keep them in.
This is a problem, which starts at the top of our unelected school system bureaucrats. For some reason these people do not want people who question them or their policies. Most of our school boards follow UN Sustainable Development Policies and we know these frown on people questioning the state on anything.
“Actually, you didn’t turn in a research paper. You turned in a random assemblage of sentences. In fact, the sentences you apparently kidnapped in the dead of night and forced into this violent and arbitrary plan of yours clearly seemed to be placed on the pages against their will. Reading your paper was like watching unfamiliar, uncomfortable people interacting at a cocktail party that no one wanted to attend in the first place. You didn’t submit a research paper. You submitted a hostage situation.”
Both of my children report near continuous proselytizing against conservative values – and thins in a town 65% Republican.
Imagine all these slow people around with right handed sharks .. it’s going to be a bloodbath.
Mind you if we could get them all to inhale the CO2 at one time (A bit like Mao’s big jump) we may yet stabilize the volcanoes for Mosher.
It doesn’t take much online research to figure out that ambient CO2 concentrations in breathing air have zero health effects at any credible atmospheric concentration.
Today atmospheric CO2 is at about 410 ppm … or 0.04% of air. Humans easily tolerate up to 2% concentration – or fifty times current atmospheric concentrations of CO2. Humans can survive up to about 20% concentration, or 500 times current atmospheric concentrations of CO2.
So even if the atmospheric CO2 concentration eventually reaches a doubling of current values at 820 ppm, it is still vastly below the level that could cause any effects on human performance, which is 20,500 ppm.
Just more hyperbolic scare mongering by so-called “scientists”.
My understanding is that submariners live in an environment of 900 PPM of CO2. If that is on a nuclear sub, then that is truly frightening! -:) I call this “paper” Horse pucky
900 ? Try 5000 , sometimes a lot higher .
More like up to 8000ppm/v. Things start to get difficult for humans at about 15000ppm/v, 1.5% as in Apollo 13. If you are worried about 900ppm/v don’t go in to a commercial greenhouse.
Or a brewery, or some hot springs, crowded movie theaters, elevators, courtrooms, operating rooms, airplanes, their cockpits, schools, exam rooms, gymnasiums, automobiles, buses, trains, some caves, basements, utility rooms, control rooms, chemical plants, power plants, and yes definitely submarines, space capsules and even mission control.
Yes indeed. And people worry about ~410ppm/v?! Crazy!
A+++!

Quite so increased levels of CO2 can have quite counterintuitive effects, according to a report to the Subcommittee on Emergency and Continuous Exposure Guidance Levels for Selected Submarine Contaminants 3 Carbon Dioxide:
“A number of studies suggest that CO2 exposures in the range of 15,000-40,000 ppm do not impair neurobehavioral performance. Schaefer (1961) reported that 23 crewmen exposed to CO2 at 15,000 ppm for 42 days in a submarine showed no psychomotor testing effects but showed moderate increases in anxiety, apathy, uncooperativeness, desire to leave, and sexual desire …”:
https://www.nap.edu/read/11170/chapter/5
It appears that rock concerts get up to about 15,000 ppm and we breathe out 20,000 ppm. It’s not surprising that we can start higher than 20,000 ppm.
I note that the article contains zero mention of ppm levels using actual digits. It’s all scary hand waving all the way down.
“…42 days in a submarine…showed moderate increases in…desire to leave, and sexual desire…”
What a surprise, but I suspect it had little to do with CO2 levels.
Was those symptoms due to “15,000 ppm” or “42 days in a submarine” I wonder?
What do you reckon the level might have been in the office where that was written then?
Of course 43 days in a submarine, irrespective of the CO2 level, might be expected to have the effect mentioned last.
Chris Hanley December 15, 2018 at 6:49 pm
Of course 43 days in a submarine, irrespective of the CO2 level, might be expected to have the effect mentioned last.
The most disparaging comment I ever heard about a sales manager: “He could not sell pussy in a submarine”.
Whenever I see articles that state “Blah blah blah scientists say” my BS detector goes off the scale. This stated to happen for me after the 1980’s BSE scare in the UK where cattle were fed infected animal offal such as brains and nerves, processed in to a dried feed pellet. Govn’t scientists told us it was safe. Shorty after people started to present with CJD symptoms and there were deaths (I don’t recall how many).
I understand BSE is now showing up, again, in cattle in the EU zone.
Was it Reagan who said the 7 most worrying words are “Trust me. I am from the Govn’t.”?
Re BSE, and then medical scientists said that a hundred thousand or more Britons would die over the next couple decades having likely already been infected with BSE. That didn’t happen either.
DMacKenzie
Mooo?
“Scientists” ? Really? Scientists came to the conclusion that the ambient atmosphere outside is Soooooooo loaded with Co2 as to make people “stupid”. “Scientists” … really ? Please define “scientist” … esp. when used as an “authoritative” source of information.
Oh, yeah? What about 100,000 ppm? Huh!? What about that!? That’s what we had when I was young, and we loved it!
Was that after inhaling?
Clearly you took a breath sometime later which is a shame.
Stupid TROLL
Documented affects don’t start to occur until you are well north of 2000-3000ppm.
Yet these guys are worried about increasing CO2 levels from 280 to 500ppm.
People like this, a room full of leftist dopes listening to Bill McKibben. (The natural gas burning fireplace in the background is a nice ironic touch.)
The major factor in “sick building syndrome” is mass psychogenic illness, with the “illness” progressing according to sight lines, not air circulation.
Many LEED buildings have problems with sewer gas ingress.
Odd that EPA’s fact sheet on Sick Building Syndrome makes no mention of carbon dioxide. SBS has been around since the 1970s when buildings were tightened to reduce air infiltration and heat demand. Ventilation standards were reduced from 1 to 3 air changes per hour down to as low as 0.35. But the reduction in ventilation resulted in high indoor humidity and reduced removal of common indoor pollutants and odors. Excess humidity leads to water condensation within walls which results in mold growth and all sorts of health issues.
CO2 has never been considered a factor. It is, however, relatively easy to measure and can be used as an indicator of poor ventilation.
By the way, there are many unvented gas heating appliances which can be used in living spaces that add significant quantities of CO2 and H2O to the indoor environment. These have Oxygen Depletion safety sensors that shut them off when O2 reaches about 18%. At that point CO2 will be at about 3% or 30,000 ppm. I can attest to the fact that it is quite difficult to create the conditions necessary to test these sensors but the concern is primarily the potential to build up dangerous levels of carbon monoxide and nitrous oxide and not CO2. Some countries (e.g. Canada) and US states do not allow the sale of unvented heaters for consumer indoor use.
Another article rediscovering the bleedin’ obvious. Gas appliances capillary soldering of copper pipe don’t have vents or sensors. While monitoring confined spaces, I used to get laughed at for suggesting the operatives opened windows or vents if available, otherwise fetch a ventilation kit. Two guys talking, soldering and of course secretly smoking? The levels could be over 2000ppm before they even started. I would set the alarm to scream at 3000. “Aagh what the F&^% is that!!”
We sealed buildings up tight…to make them more efficient
…then install ventilation systems so we don’t die

The Truth About Vent Free Gas Heaters
http://www.infraredinfo.com/Article_2.html
I would tend to believe that Radon would be the cause of stupidity becauyit is the dominant air quality problem in most homes, at least in the mid-Atlantic and Northeast
Like they say about hard times not building character, but rather revealing it – CO2 has not made people stupid, it has only revealed the latent and inherent stupidity in a lot of people.
True, and we would be better off if many of them stopped breathing.
Gosh! The folks working in major greenhouse operations (1000 – 1500 ppmv CO2) must be near zombies! And the high CO2 levels are caused by global warming…. and the bottled CO2 gas they are releasing into the green houses to invigorate and accelerate plant growth.
J Mac
At least we now know why plants don’t talk.

I a total of 4 years under water from 1964 to 1970
“While on active submarine patrol for 57 days, 7 out of 15 crewmen exposed to CO2 at 8,000-12,000 ppm developed decreased plasma calcium and increased erythrocyte calcium (Messier et al. 1976). There were no changes in parathyroid hormone or calcitonin (Messier et al. 1976). Some observational data from submarine patrols documented increased urinary calculi in crewmen when CO2 was present at >10,000 ppm most of the time, instead of at <10,000 ppm (Tansey et al. 1979). There are several physiologic reasons why that is not thought to be causal; in particular, the incidence rate of urinary calculi observed in submariners does not seem to exceed the general population rate. Exposure to CO2 at 50,000 ppm for 30 min led to increased renal blood flow, glomerular filtration rate, and renal venous pressure, as well as increased renal vascular resistance (Yonezawa 1968). These physiologic changes related to renal compensation for CO2-induced acidosis are considered to be innocuous. Thus, electrolyte, bone, and kidney effects are not appropriate end
Now that’s what I call scientific discourse! Obviously far too difficult for a typical climate change journalist.
My cousin was a submariner here in the navy in Oz. He once mentioned that for some unknown reason submariners almost all have daughters not sons. Was this a consequence of higher CO2 levels ? Don’t know.
And an air force pilot mentioned the same phenomenon caused by proximity to the aircraft radar. I mentioned to him that a more plausible explanation was that Y-chromosome sperm swim better when a woman achieves orgasm – something to do with the ph of the cervix. Thus rather than radar the true cause was ineffective technique. He wasn’t amused.
Nah. My brother was an officer in a nuclear sub for years and had three sons, no daughters. He confirms that they routinely ran with 5000-8000 ppm CO2, and even above 10,000 at times.
No, it’s long absence from home. Nature interprets this as having insufficient females in the population and corrects it.
As usual, they have it entirely back to front. The people who are tired and/or stupid are under the belief and impression that ‘surging’ levels of CO2 are making changes to the climate or Global Warming.
and the fact most eat junk food for lunch then need a sugar hit for afternoon smoko and perk up till knockoff..
lot of tradies in Aus use coffeemilk for breakfast or on the way to work and its got massive sugar in it,
another at 11 and lunch and smoko
if its not that its the damnable coke a cola hits
nowdays is being immobile for hours staring at screens, no freshair or excersize between times.
and yes the stupid is from our pathetic ed systems as well.
The people who are stupid are looking for any excuse other than the truth. This seems very similar to the CAGW crowd.
From NAP.EDU:
Emergency and Continuous Exposure Guidance Levels for Selected Submarine Contaminants: Volume 1 (2007)
“CO2 exposure did not affect performance on the tracking task or any of
the six RPM subtests (Storm and Giannetta 1974). There was a learning effect for the tracking task during both pre-exposure and recovery, but the authors still thought it was appropriate to conclude the absence of a performance impairment. The authors considered it especially likely because previous pa- pers had suggested that impairment is easier to detect during skill reacquisi- tion, which occurred following the 2 weeks of exposure without practice, rather than at an asymptotic skill level (Storm and Giannetta 1974). Thus, CO2 at 40,000 ppm for 2 weeks did not affect performance on multiple tests of cognitive function in physically fit young airmen, a population probably not unlike submariners.
Based on the work of Storm and Giannetta (1974) and Glatte et al. (1967), a NOAEL of 30,000 ppm for general CNS effects could be proposed.”
CO2 is a toxic gas if over 20% of air, (200,000ppm)
Oxygen is a toxic gas if over 50% of air pvp (500,000ppm)
CO2 build up in the blood is the trigger for the breathing response, not lack of O2, and don’t forget that it’s the reduced O2 levels that causes a problem in humans and not increased CO2. Reduced blood CO2 levels reduces O2 uptake in blood/increased blood CO2 levels increase blood flow and increases oxygen uptake and relaxes muscles/brain. (think hyperventilation)
In our lungs the CO2 level is in the range of 2.7 to 7.5 % (but an average of 6 %)
Thats 27,000 to 75,000 parts per million (which is 67 to 187 times greater than in air ) !
so yes the lungs do admit air at 400ppm but as the air reaches the lungs it mixes with the residual volume (approx 20% of 6 Litres) of heavily CO2 loaded air, the lungs never get to see 400ppm but normally never less than 27000ppm (say 3%)
O2 volume of air is 20.8 % Lhaza, at 3,658m has a lower pressure which equates to around 14% pvp just for interest
So , we breath in air at 20.8% O2 and breath out at approx 16% O2 (that 5% is what gives us 100% O2 saturation in the blood, hence no more is absorbed, hence remainder is exhaled) Who gives fig about CO2 in air ?
Yeah, just another BS study that shows they’re jumping the shark.
R Shearer December 15, 2018 at 6:39 pm
Yeah, just another BS study that shows they’re jumping the shark.
Yes, but they are getting away with it.
Unfortunately, you’re mostly correct, but there’s a fighting chance, and when has there ever been a time when insanity doesn’t raise its ugly head?
At the Sydney Morning Herald here in Australia an article, of many usually daily, was published about how coal burning is killing the planet. One commenter stated that burning coal, and thus spewing in to the air millions of tonnes of CO2, was increasing shark attacks! Serial!
The issue is 99.9% of people watch MSM and believe the 97% of “climate scientists” (All 75 of them from the AGU survey) that CO2 at ~410ppm/v is “dangerous” and are completely ignorant of how their own bodies work.
There must be an international climate conference in the wind ? (/s in case)
Yes and as usual they agreed to agree, except for the parts yet to be agreed in a future meetings.
These non binding agreements that all but a handfull of countries failed at, even thought they set there own targets are encourage to make more ambitious targets because they didn’t fail their moderate targets by enough.
Developed countries are encouraged to make outrageous assistance package claims they have no intention of honouring to developing countries with imaginary climate damages and in the name of world human social justice.
The important part is we have made these fantastic agreements and all striking school children will be able to go back to class, safe in the knowledge we saved the planet.
Did I miss anything out?
It sounds better if it’s written as, “surging levels of greenhouses gases are making tired and stupid scientists.” It seems that there’s a lot of that going around of late.
I thought they were talking about the surging CO2 gasses emanating from the mouths of alarmists were making people stupider…?! They certainly make the believer-drones I encounter more stupid. Much more stupid in fact. Although they were pretty damn stupid to begin with. Ha ha…what a crock-o-shit. For Millennial consumption only.
What is next to blame because of global warming? The next thing will be increased divorce scare because of CO2 now that we “KNOW” that CO2 causes poor memory and poor concentration, leads to heart attacks, is carcinogenic, shortens the life of individual cells,…………………..etc. In fact HIGH levels of CO2 will cause men to lose interest in sex, women to abandon their kids, and other general mayhem. WE ARE ALL DOOMED BECAUSE OF A MOLECULE THAT IS ESSENTIAL TO LIFE ITSELF. /sarc
The world has gone absolutely stark raving mad.
“The world has gone absolutely stark raving mad.”
Not the whole world. There are still some sane people remaining. After all, Trump got elected. 🙂
Oh , and the piece claims we will be four or five times the present levels by 2100 .
Riiight ….1600 to 2000 ppm !
And pigs will fly ….
We couldn’t reach those levels of CO2 in the atmosphere if we burned all the fossil fuels available. I think about 800ppm-1000ppm is the best we could do if we burned it all.
At those levels, we will be harvesting two days before we plant the crop.
I know it is true because I readed it on ta interwebs.
And of course the photo to go with the claim

shows steam and water vapor, not CO2.
Sophie Law … ‘journalist’ …
You just made the planet dumber Sophie, and all it took was your writing.
You made an error she is a … fiction author
In my experience, the Daily Mail is not noted for the quality of its writing employees.
“Based on the requests for comments section [on the reliable sources noticeboard], volunteer editors on English Wikipedia have come to a consensus that the Daily Mail is ‘generally unreliable and its use as a reference is to be generally prohibited, especially when other more reliable sources exist’.
“This means that the Daily Mail will generally not be referenced as a ‘reliable source’ on English Wikipedia, and volunteer editors are encouraged to change existing citations to the Daily Mail to another source deemed reliable by the community. This is consistent with how Wikipedia editors evaluate and use media outlets in general – with common sense and caution.”
Clearly, for those who believe the carbon dioxide is a pollutant fake premise, and rely on its scare work to ensure funding from dumb politicians, one could say that this is their only valid premise. For it is demonstrably clear that their work’s results demonstrate the problem they claim, and notably those closest to the gravy train.
I don’t think it’s the CO2 but I do think the scientists are hoping it continues. Easier to sell pseudoscience to slow, zombie types.
Obviously, were it not for increasing levels of CO2 they could not have reached the (grindingly stupid) conclusion that they did.
QED
QED is Latin for ‘Well duh!’
That paragon of garbage press, The Guardian, has apparently left the scene with the departure of the reporter who created that rags’ hysterical stories. Not to be deterred, the posters here have found multiple replacement sources for the worst in alarmist Hair-On-Fire garbage to be highlighted.
Of course I am talking about that wonderfully stinky MSM rag, The Daily Mail, and our hard left wing propaganda outlet, The L.A. Times. And to round out a trio, we have EurekAlerts. “Science” reporting written up by “journalists” who do not have even the most basic grasp of the topics they attempt to expound upon. Press reports from EurekAlerts are the closest thing to purely content-free announcements we would ever hope to see. {As an aside, content-free journalism may well be a reflection the content-free education the journalists got at the modern University.}
*******************************************************
I have a proposal.
A Modest Proposal:
{For those who do not know, see Jonathan Swift, author of Gulliver’s Travels, who wrote “A Modest Proposal”, a plan for the treatment of the children of poor people.}
As has been documented above by numerous commenters, CO2 levels must be vastly higher than what is seen, before there any noticeable effects. It is all a basic matter of physiology, and will be well known to any Biology major at a Junior level at any college.
Then, My Modest Proposal:
If a piece makes claims which would make any science majors at GSC (Generic State College) blush in embarrassment, then the piece probably does not rise to the standards to appear here.
Thinking about CO2 obviously makes scientists so dumb and slow they will lie and scam.
Did they measure this or model it? If they measured it did they bother to measure the CO levels? I f they had I might be less skeptical of their conclusions.
Well, Sophie Law For Mailonline, you better inform NASA and the US DoD about this ASAP.
NASA has set the maximum allowable 24-hour average CO2 on board the manned International Space Station at 5,250 ppm (4.0 mmHg). NASA used to have an even higher maximum such limit of 7,000 ppm on the manned ISS.
“Data collected on nine nuclear-powered ballistic missile submarines indicate an average CO2 concentration of 3,500 ppm with a range of 0-10,600 ppm, and data collected on 10 nuclear-powered attack submarines indicate an average CO2 concentration of 4,100 ppm with a range of 300-11,300 ppm,” according to a 2007 National Research Council report on exposure issues facing submarine crews. The NRC noted that a “number of studies suggest that CO2 exposures in the range of 15,000-40,000 ppm do not impair neurobehavioral performance.”
I can only speculate that the pragmatism of ISS and Navy submarine operations engineers has discounted all of the dire warnings from CAGW alarmists about humans living with ambient CO2 levels that would make their employees—in tasks of life-or-death decision making—tired, slow and with disrupted memory and concentration.
In other words, good grief!
Exactly. Ambient levels in subs in the low 5 figures are not a worry, and the expectation is that during tests or stress or actual combat higher respiration rates would tend to raise CO2 even higher. The US Navy and US Govt have studied this in detail and there is no loss of memory, mental acuity, concentration, dizziness, or other deleterious effects that would impair a combat crew at anywhere up to 100 times current atmospheric concentration of CO2.
This is simple stuff to find in the literature. How can someone honestly make such ridiculous claims? How can they get published when it is nothing but rubbish?
This is just what we need. Another thing to blame for stupid or lazy behavior.
In the 70’s, I worked for weeks at a time in an atmosphere with CO2 levels that averaged 7000 ppm. Anyone who has served aboard a submarine can attest to the fact that there is no loss of cognitive function even at those extreme levels. You can’t stand watch for twelve hours every day if you’re exhausted from the high CO2 levels. I just throw the BE flag on this study. But it does expose the sad state of peer review in our current climate
Terry Sholes
“Anyone who has served aboard a submarine can attest to the fact that there is no loss of cognitive function even at those extreme levels.”
I’d effing hope not.
Childish wrong articles like the one reported will make people sicker and more stupid than CO2 ever will
