I didn't know that!
A couple of refrigeration engineers died near us at a poultry processing plant after it was found that the on-site liquid nitrogen tanks had a small leak. CCTV showed them just happily working in a room without ventilation and they just died. Was all very sad.
Also, was this paper AI written?
> "There is now a considerable body of published data showing impacts at levels < 1,000ppm CO2, although the effects of exposure remain controversial."
Which is followed by this, with the very AI "For example" that seems to mostly contradict that statement?
> "For example, one study found no impact of exposure to levels up to 15,000 ppm (Rodeheffer et al., 2018), however the study population was a group of highly trained US Navy submariners. Conversely, studies in young adults (Satish et al., 2012), office workers (Allen et al., 2016) and university staff/students (Snow et al., 2019) showed negative effects at CO2 levels as low as 950 ppm."
And then "Such studies are supported by assessment of CO2-induced changes in human brainwaves, measured by electroencephalography (EEG) combined with cognitive tests (reviewed in (Zhang et al., 2024)). Such studies show that exposure to CO2 between 1,000 and 2,500 ppm results in heightened brain activity."
"Such studies" ... "such studies". And these studies seem to contradict the proceeding statement even more?
My office, with the window open, surrounded by trees and in the countryside, and the nearest large town being 20 miles away, shows 422ppm CO2 pretty consistently.
We're already slowly adapting to higher CO2 levels by sitting mostly indoors that have elevated CO2 from 500 to 800 with ranges up to 1500 (taken from my measurements at home).
Claiming that it would be toxic doesn't pass the most basic checks that humanity experience already.
> We're already slowly adapting to higher CO2 levels by sitting mostly indoors that have elevated CO2 from 500 to 800 with ranges up to 1500 (taken from my measurements at home).
But won't that 1500 be even higher indoors as CO2 in the atmosphere increases?
Diving is not a 24x7 activity, and so it doesn't relate.
In general, it is true that there are many causes of a rise in bicarbonate, but doesn't this only makes the situation more precarious?
It’s not “whataboutism”. It’s a basic control in a paper that takes population data and asserts a causal link between a complex, personal biological variable and a global phenomenon.
There are probably dozens of factors that matter a lot more to individual blood gas levels than global average co2. At a minimum, I’d expect to see controls for obvious medical factors before taking this argument seriously.
Imagine a healthy person with a healthy lifestyle and 8 hours of sleep every night. But every year, they are awakened 5 minutes earlier. So after 6 years they are only getting 7.5 hours of sleep every night. After 12 years, it’s only 7 hours. Will this have a health effect over time?
Obviously that example is a pretty big impairment. But the concept is what I’m getting at. Small persistent changes compound over time if there is no relief for recovery.
They're called houseplants.
Better systems are being researched.
This is actually a crazy thing that some of the very wealthy are doing in mountain homes. They have O2 tanks setup with their homes so that when they arrive they don't experience altitude sickness.

Doesn't help if atmospheric CO2 levels increase to unsafe levels, though.
There is also a Ted talk about taking this to an extreme, which does seem to anecdotally work: https://www.youtube.com/watch?v=gmn7tjSNyAA&pp=ygURdGVkIGthb...
The most efficient system is algae, but you require a pretty massive amount of it to compensate for the amount of CO2 a single person emits.
Fwiw, my value reliably went down after I replaced citrate mineral supplements (calcium and magnesium) with glycinate capsules.
the entire upper atmosphere would be turned to nitrogen dioxide
even the side of earth not facing the burst would have all life die very quickly because the ozone layer would just be GONE, so now all lethal ultraviolet solar radiation gets in too
solves ALL our problems
unfortunately Congress might survive a few more months in their underground bunkers but they are eventually doomed too
The surprise is nothing was real was done. Compare what our generation did with this knowledge against the sacrifices the WW2 generation did. In WW2 many items were rationed in the US for the war effort, including gas.
We knew something had to be done to be done in the 70s, but did we sacrifice our lifestyle for the good of the world ? No, our self-centered generation pumped even more CO2 into the air and is continuing to do so. Our grandchildren will pay dearly for what we did and are doing in decades down the line.
Still, we know that very high sustained carbon dioxide does risk respiratory acidosis and a rise in serum bicarbonate. The question then is whether a lower sustained rise also has an observed effect.
Fwiw, as per Figure 2A, thus far we see a linear increase in the data, with no sign of it being asymptotic.
If your smart switches support it (Tuya/Lidl gateways doesn't, so there is still work to do), you can get some cashback when they momentarily turn some devices on or off to help offset imbalances on the power grid without relying on gas turbines.
Software is allowing governments to provide services online, 24/7, making driving to their overly large buildings a thing of the past.
Software is changing the way companies work with their customers and suppliers. It cut business trips so much that airlines like United had to review their routes at some point.
Software allows more trains to run on each track, and improves cross border services in dense areas in Europe
Software developers who support open source initiative such as LineageOS, ChromeOS or lightweight Linux distributions allow to keep devices for longer. It is valuable when manufacturers and Microsoft would like you to buy new hardware.
YouTube tutorials and online marketplaces allow customers to fix their old stuff or to buy second hands. It makes the economy more circular than it used to
Simulators allow new generations to fly cessnas or race cars on 1000 electrical watts at home, while video games allow kids to have fun together without racing cars on open roads like you used to
Given that this is known required input, we can start by expediting the building this energy infrastructure with all due haste. This would require ignoring various activists with a litany of reasons for why deploying solar/wind/nuclear/geothermal at scale is stupid/immoral/unethical.
The end state is to have a direct humanless assembly line turning Earth into cheap crap for monkeys to use once and throw away, with ginormous global GDP. Happiness for everyone.
I thought it was quite funny TBH
For example, none of the improvements in combustion engine efficiency over the last 40 years have results in less gasoline being used, it resulted in bigger, more powerful cars and more driving of them.
Really the biggest lever is reducing human population growth and mandating renewables when they are workable, even if moderately less economically viable.
Politically, block the straight of Hormuz, attack oil-producing infrastructure. Trump and Zelensky and even Iran are doing us all a favor.
Also imagine that meat can in theory be lab grown.
Edit: the only positive response in this thread and I get downvotes lmao what the hell people.
Because it's not "positive", it's "techsolutionism", which at this point is basically a cult... let's keep shovelling more shit on the gigantic pile of shit and pray it gets smaller
As long as it's free for individuals to pollute, we are going to demand polluting products & services without regard for the environment.
The solution is to price externalities, but your fellow citizens will vote out anyone who suggests those cuz they like polluting for free.
Collectivism will fare no better unless it's a dictatorship (which they all devolve to eventually, but putting that aside...) After the people's revolution they will demand the right to unlimited driving for $0 and stage a revolt should the vanguard elite suggest that unlimited driving for $0 might not be good thing.
1. Eating collagen supplements has not been established as a necessary dietary requirement. Your cells synthesize collagen from amino acids, with vitamin C serving as a required cofactor. Some trials report modest improvements in wrinkles, skin hydration, joint pain, or bone measures, but that supports collagen as an optional targeted supplement, not something everyone must consume to remain healthy.
2. Bovine is common, but commercial collagen also comes from porcine skin, chicken cartilage, fish skin/scales, and jellyfish. A randomized clinical trial, for example, used pork-skin collagen, while another tested fish-derived collagen. Actual collagen is animal-derived unless produced through recombinant biotechnology.
3. “No synthetic amino-acid mixture comes close in effect.” This lacks evidence. In a 2025 randomized double-blind study, participants received 30 g of collagen hydrolysate, a free-amino-acid mixture precisely matching collagen’s amino-acid profile, or placebo. Collagen and the amino-acid mixture produced similar blood amino-acid increases, and neither increased muscle connective-tissue protein synthesis versus placebo over six hours.
0. There is near-zero risk of prion disease from cows in the US considering they're domesticated, not wild. There is no recent history of it either in the US. Collagen hydrolysate is highly processed to be short-chain.
1. As one gets older, vitamin C, no matter how much of it is consumed, is useful but insufficient for collagen synthesis.
2. You're right in theory about chicken/fish/pork collagen, but the commercial availability of their derived collagen hydrolysate is terrible or contaminated. Only bovine collagen hydrolysate has excellent and contaminant-free commercial availability.
3. You're measuring the wrong thing. It is not isolated amino acids have the resulting healing effects. It is only peptides, and these are poorly synthesized from plain amino acids.
Wait until you learn how 99.9% of cows are treated lol
Also, sleep health is an independent consideration for which it benefits.
This is, nine times out of ten, a bullshit diagnosis, and here is why.
Providers have systematically and knowingly misidentified arthrosis and other degenerative diseases. Because guess what? You can medicate and relieve inflammation, but -osis is not curable and very difficult to heal.
So rather than tell the truth to elderly patients with degenerating bodies, the providers lie and say there is inflammation. Then the providers recommend a panacea, literally, that matches that bullshit diagnosis, and the arthrosis patients go on their merry way with “arthritis” pills in their pockets.
It is an extreme disservice to suffering people, but that is how capitalism and health care work.
