It gets better, at current rates of carbon emission we have until ~2050 before the atmosphere increases bicarbonate levels to the point where basic metabolic processes begin to breakdown.

Wow, so we are actually cooked. From the inside!

geez. 7% since 99 so more than a quarter percent per year but I bet its going up faster more recently than at the turn of the millenia.

My dad had COPD, which also increases the CO2 levels in the blood. His body was able to adapt to the gradual increase as his illness progressed, the problems arose when he had even the mildest illness, causing a rapid spike. His body couldn't adapt fast enough and suddenly he'd be on oxygen but still asphyxiating. It was awful.

Yes, you are a walking swamp in a balloon. What CO2 is doing to the ocean will also happen to your insides. There is only an extremely porous membrane between the two.

We can also expect changes to our microbiome, water saturation levels, running temperature, etc, just like everything else.

How about a little something to lower your spirits, the physiological effects from rising CO2 include acute cognitive decline. Fortunately have not noticed cognitive decline in any human populations so far.

I didnt really understand just how useless the rosy glasses outlook were about this topic until I saw this video about the topic: https://m.youtube.com/watch?v=0KQYNtPl7V4&t=2874s&pp=ygUUYmFkZW1wYW5hZGEgYmFkIG5ld3M%3D and yes Its a long video but if you can somehow survive thisbvideo without seeking out therapy after? ...I would question if youre human. Seriously.

And THAT is why Ill never buy a car or have kids. Im not hastening the armageddon or destroying a child's life. I feel sorry for those who already have kids....

Summary: Rising carbon dioxide in the atmosphere may be leaving a measurable imprint inside the human body. Researchers analyzing more than two decades of U.S. health data found that blood bicarbonate levels have climbed about 7% since 1999, while calcium and phosphorus have declined—changes that closely track increasing atmospheric CO2.

I guess it makes sense - the more CO2 you breath, the more your body has to deal with, and it's physiologically relevant.
