Ha! Joke's on you, scientists! I'll be dead by then!
This is not what I needed to start my Saturday morning with
Given that the entire evolution period for humans has seen a stable and relatively low atmospheric CO2 level (< 300 ppm), it’s possible that our physiology is finely tuned for a range of CO2 that will not be much greater than this level. As the atmospheric CO2 levels rise, already at 420 ppm, the increasing levels of bicarbonate, and decreasing levels of calcium and phosphorus in our blood represent permanent and growing changes in human blood chemistry. These changes can be explained by CO2 retention and overload in the body. The extra CO2 being inhaled isn’t expelled via increased ventilation, as ventilation rate is controlled by pH which has likely remained stable due to acid-base regulation. CO2 storage in the body then becomes a major issue presenting a risk to population health and an existential threat for many species especially given that the rise in atmospheric CO2 may be a phenomenon that has significant momentum. Realistically, to mitigate this approaching threat, the alarm needs to be raised immediately. Unfortunately, currently there is little awareness or inclination for action on this issue.
Doesn't improve Sunday mornings either
Now, now, I've been assured that CO2 is not a pollutant
"Well, I guess it's time to wrap up this experiment called human beings up. It was a good run."
"Climate change will likely wipe out most of what we recognize as life..."
"...well, I guess its time to wrap up all of life then... please hug me."
"No."
It's not that bad. We are not able to wipe out all recognizable life. The whole freaking planet was frozen over once, and life recovered. Give it some million years and new species will evolve to fill the empty niches. Just don't bet on primates being around to tell the tale.
Time to watch 'up' again.
i thought we needed to be closer to 800- 1000 pom for this to be a significant problem but that might have been me confusing studies on cognition with this ?
it would be nice if it sent us sterile.

600ppm is the place where it start affecting human cognition from what i recall. there was a dude in the reddit back in the day called MrVisible that was obsessed with this and had a whole sub about it . i thing it was called r/doomsdaycult or something like that.
EDIT: i just went to find that old sub and reddit banned it of course . maybe a reddit archive will have it.
We're here as stewards to this planet and all of her life. We've failed at it all in our quest for money, power, and greed. I for one don't feel bad for us one bit. I do feel bad so many innocents will have to suffer, but we did nothing to stop this and it's what we deserve.

No, you are not. Just stop touching things and all is good.
And when you see an animal suffering and in need you just keep walking and pay it no mind?
Yeah. First rule in nature-related professions is generally to not touch. Careless touching can get the animal to be outcast or you to spread a sickness. And in the end, it's only to satisfy human kind instinct or morals anyway.
But "touching" was meant metaphorically. Our understanding of the larger picture in nature is only starting to surface. And general consciousness is still far behind the influence we have on the world as a species.
We have already created a garden world in europe (because it's the old continent) and have done a lot of damage in the process, the last few millennia, including "good practice" of managing woods creating only problems.
In short: do not touch nature, unless you know exactly what you do. And we especially don't need to "manage" it.
Ah, this helps put into perspective why the West is so cooked and we're sleepwalking into WWIII, lack of empathy and total apathy. I guess this is what we deserve.

A good thing is to learn to differentiate between 'emotional/gut reactions' and 'empathy'. A simple example can help: who do you think is the most helpful person (aka, showing empathy) in that hypothetical situation: two witnesses faced with a tragic car accident involving a little kid being badly hurt.
- The first witness immediately starts crying all the tears of their body, running around and shouting 'omygodomygodthatishorrible!' (which, we will probably all agree, it is) and starts blaming the driver (which maybe is to blame, or maybe not) and calling them names?
- The second witness that focus the only thing that matters (which is not blaming anyone): the child that is hurt, and that immediately calls 911 and do it as calmly as possible in order to be able to describe as precisely as possible the exact situation to the emergency respondents?
Ah, this helps put into perspective why the West
Are you being serious?
The comment you just replied to is one of of the most well grounded and sound I've read in way too long. Your... 'reaction' to it only demonstrates how badly we need to hear it a lot more often. A lot.
Also, a warm 'hello' from the West, wherever you living your perfect and faultless existence.
Ha, certainly I was being a bit hyperbolic. Still, I will help any animal wounded and not actively being pursued by a predator. You can denigrate me for that if you'd like, but I can't stand to see any life suffer.
You can denigrate for that if you’d like,
I'm not the one telling people they're bad persons because they show no sign of what you call 'empathy' and then explain it was just 'being a bit hyperbolic'.
Have a nice day.

Wholly beside the point.
Not really. It's all human nature. Some have empathy and others don't.
Which is beside my point. And acting on empathy while creating damage is egoistic.
Damage by your standard. Saving a life by mine.
If you know what you do. Which is great. But my point is; we, generally as a species and in nature the last few centuries, we did not. And still touched.
