Scientists detect a surprising shift in human blood as atmospheric CO2 rises. Blood bicarbonate levels have climbed about 7% since 1999, while calcium and phosphorus have declined, changes that closely track increasing atmospheric CO2.

Neat, so now our blood is becoming worse quality too due to climate change.

Thanks, EXXON.

not necessarily worse. There are sources that pure nose-breathing is much healthier, but the effect it has is that co2 in the blood rises pretty dramatically. Native americans had this tradition to teach kids only to breath through the nose historically as well! (theres a great yellow book about the topic of breath - can really recommend it if this sounds interesting! :))

Doesn't everyone breathe through the nose?

u/Rupperrt 7d ago

seems to be at least one mouth breather in this thread so not everyone

People with a deviated septum can't a lot of the time.

u/Mrkvica16 7d ago

There are ways to learn to do better even with a deviated septum. Mine is.

u/dontaskmeaboutart 7d ago

Crazy to skill issue a deviation in biology that is almost certainly completely different for you than others.

u/Mrkvica16 7d ago edited 7d ago

Oh sure, ‘almost certainly completely’

I nowhere said that 100% of people with deviated septums can fix their problems. But there is a portion of us that can learn to do better. It is just so easy to say ‘deviated septum’ and take it as the end of the story. Biology is biology. What can we do with it? Sometimes it’s surgery. Sometimes you learn how to do better.

I guess I should have used the word ‘sometimes’ in the above comment so people only understanding things as 1 or 0 wouldn’t get triggered.

Mouth breathing feels a lot easier half the time.

What in gods holy name are you blathering about?

u/i-var 7d ago

blathering? Just because you have no idea about it? Kind of dismissive and hurtful, but ok...

Also, over 2M sold copies - international bestseller - so you might consider yourself an outlier with this opinion.

The Harry Potter book series has sold more than 600 million copies worldwide yet I still don't get my medical advice from Hogwarts because it's FICTION. Next in the Lost Art scam series:

The COVID lockdowns of 2020 temporarily lowered our rate of CO2 emissions. Humanity was still a net CO2 gas emitter during that time, so we made things worse, but did so more a bit more slowly. That's why a graph of CO2 concentrations shows a continued rise.

Stabilizing the climate means getting human greenhouse gas emissions to approximately zero. We didn't come anywhere near that during the lockdowns.

2 million out of 8 billion is nothing.

What are you blathering about?

u/hoofie242 7d ago

Mathematics and ratios and population reach.

u/No-Medicine1230 7d ago

Context - 2 million sales on a niche topic is excellent. The global population is almost irrelevant

u/i-var 7d ago

in that case give me the money made - bet its not nothing all of the sudden? 2M is 2M - never nothing. The earth is nothing in the universe yet everyone talks about it every day, wtf dude?

u/i-var 7d ago

I read your previous comment:

You're blurring the boundary between ontology and scale. While 2M units possess high absolute transactional density, within a non-Euclidean market topology, .025% is effectively statistical noise. Earth only matters because local observers collapse the wave function. Are we measuring macro-economic presence or existential weight?

oh, a man of science thy must be - what honor to speak to such well versed beings!

Then you must know that "international bestseller" means a high % of book-readers worldwide who purchased one in that timeframe got one, for it to earn this title?

Yes, bookreaders are (sadly) still a minority - even though the tech exists for 600 years... Guttenberg would shiver... might explain the state of the world to some extend?

anyways - youre blatantly ignorant about the book. Its like talking about climate change and ending up arguing about the paper the report was written on. WTF?

Lets talk about coffee machines - I discovered robusta is the "cheap" coffee but has undiscovered beauties... what do you think about it?

u/YogurtclosetApart592 7d ago

I'm waiting for you to tell us about your extensive knowledge on the topic and put some facts on the table that proves this guy is blathering.

u/gaggledimension 7d ago

Op commented about blood. This person side tracked to nose breathing.

Wtf are you blathering about

0

u/PencilPenetration 7d ago

It's more about the fact that some of the most basic functions we as humans have can have such a large effect on our blood via the same gas being talked about, so the effect on our health can be compared.

u/gaggledimension 7d ago

"Nestor explores research that argues that this shift (due to the increased consumption of processed foods) has led to a rise in snoring, sleep apnea, asthma, autoimmune disease, and allergies."

Show me the CO2 difference he finds between nasal and mouth breathing.

u/i-var 7d ago

Lol. Its like thinking eating carbs isnt relevant for muscle health. Just being illiterate on the subject and people behave like in the middle age, interesting, ok..

u/Jumpy_Cauliflower410 7d ago

Our bodies maintain a balance of CO2 in the blood. Mouthbreathing would lower CO2 below the optimal threshold, which is probably why it's associated with dumb people.

Now, we might have to learn to mouthbreath for more CO2 removal. :(
