Should not be a surprise since we have know about CO2 Levels and fossil fuels for many decades. 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…

I assume you mean boomers? Might time to stop blaming them, since at this point some of them are great-great-grandparents and the following generations do not seem to have shown any more appetite for changing course.

> at this point some of them are great-great-grandparents

And yet, insanely, they’re STILL the generation in power. Still breaking things even in their dotage.

Anyone else ever think of somehow building an at-home carbon-removal system, for lower carbon content in the air of your living spaces? I know it's a silly idea, but one that has occurred to me from time to time.

Yeah, too many homes were built without fresh air intakes into the HVAC systems. There are definitely reasons you don't want it always pulling in outside air (temp and humidity differences, for example), but it would be nice to have the option to do it once a day just to freshen things up.

They do make HRV and ERV, but not exactly a simple retrofit for existing houses.

dafuq is wrong with y’all and normal English sentences?

It's strange and unnecessary usage. LLMs generate normal English sentences which sometimes look strange and have unnecessary bits.

I’ll tell you what’s unnecessary is prickly commenters who call out ordinary English writing for no fuckin’ reason except to smell their own fuckin’ farts, so MYOB

You may just be joking, but such a thing would be a crime against humanity.

Sounds like a forced sustainability measure to me. Nothing wrong if we're made into herbivores, except maybe the non-human herbivore populations running rampant and competing.

The competition is worse with the actual situation : cows are herbivore, pig are omnivores but fed plant-only. Chicken and fishes aren’t relevant for Alpha-gal syndrome but they’re also mostly fed by plants (and other fishes) anyway.

It may be counter intuitive at first but a vegetal diet needs less plants in total than an omnivore one.

Historically levels were around 250 and now they're generally over 450. I wonder if I would feel a cognitive boost or just plain better in general if I were breathing 250. Do they sell home CO2 scrubbers? I can easily increase the CO2 in a room, but how about decreasing it?

You can form a simple CO2 scrubber by buying colorized bulk soda lime, putting it in a HEPA filter bag, and running air through it, but it's very expensive. It'll probably cost $100 a day. Also, you'll still be on the hook for maintaining good ventilation so as to remove indoor bioeffluent VOCs. Better systems are being researched.

You can also buy an at home oxygen concentrator for around $125 usd and try it. Iirc it uses atomic sieves that filter out anything larger than oxygen and then releases the oxygen, so it can run for a very long time without replacement.

It's also fun to see how it affects things on fire. The weak little jet of air from the one I bought can turn an lit incense stick into a pillar of fire.

There are likely health downsides to them for otherwise healthy people so I wouldn't suggest using them frequently for breathing purposes, but they can help with short term aerobic output and exercise if you are training at the edge of your physical capability.

Huh. Are you denying the upper safe level of serum bicarbonate? Just because we can tolerate 800 ppm of CO2 doesn't mean we can keep pushing it forever; there is clearly a limit. I suggest actually reading the paper. Diving is not a 24x7 activity, and so it doesn't relate.

saturation diving IS a 24x7 activity, people often spend weeks in underwater pods. And the point I was trying to make is that the premise behind the paper doesn't hold up to scrutiny when indoors CO2 levels are already elevated like that.

> when indoors CO2 levels are already elevated like that.

That's not a good argument, considering this could in principle be a direct cause of the high bicarbonate.

The same thing anyone else can do: bomb an oil refinery.

Which will do nothing about demand from your fellow citizens to consumer refined oil products such as gasoline, so another refinery will be built and they will carry on as usual. 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 thos…

I'm not condoning ideas like that of GP, but it literally is a way to force externalities to get priced in. If oil infrastructure kept getting destroyed, the price of refined oil would rise and the investments would shift to cheaper energy where possible.

One interesting thing in the paper that I didn't think of, is that our breathing mechanism is tied to CO2 levels. And therefore, higher CO2 levels (not atmospheric high, but artificially high during studies), can trigger panic attacks and general stress. A slow suffocation hallucination, kind of. Even when there's still sufficient oxygen, your body doesn't "measure" oxygen! I didn't know that!

Correct. Depth and frequency of breathing is regulated 90% by arterial CO2 level due to a direct, potent servo feedback based on a sensor in the brain stem. The rest is due to O2 level. A fatal situation happens with low CO2 and low O2 that doesn't increase breathing. Pneumo doctors hate this and it's an absolute indication for intubation and mechanical breathing.
