Re: CO2 overload in blood suggests toxic atmosphere within 50 years
#42I'm a bit confused by this, since indoor CO2's higher (double?) so wouldn't we already be experiencing it?
But doesn't this mean that the new indoor level will be new outdoor level + the increase that arises indoors?

No. Even with the amount of co2 current being dumped into the atmosphere there's not enough total solar energy capture to Venus things up. A few thousand years, absolutely. To add: desertification and more or less removing the support systems for modern population levels can easily happen with what's going on. But the oceans won't boil first. Everything else will die first.
Why are you only talking about co2 if you're going to try and be serious when responding to a joke? Please make an attempt to understand the situation better if you care that much.
because, intentionally or otherwise, your joke is 'too on the nose', as comedians put it, and 'will the oceans boil first' is, unfortunately, not an unreasonable question to ask, as during any positive feedback loop there is the chance for it to go into runaway. The second planet in our solar system likely experienced just such a cascading change, for example. Earth hasn't gone there before, or we wouldn't be talking (that so-called 'weak anthropic effect' Stephen Hawking was on about in _A Brief History of Time_,) but there is no a priori reason to think it _couldn't_, given a sufficient carbon pulse.
That said, we're more likely looking at more of a prehistoric scenario, near as I can suss, which would be more like, 'most high-metabolism creatures can't hack it, but at least you get some really cool massive dragonflies!'. This is emphatically a place we've been before, and, given all the prehistoric carbon now in every breath, a place we will likely be seeing again, and soon.
I'm very sorry about your planet and you have my condolences.

You can get a decent CO2 meter from stores like IKEA. You’ll come to the conclusion that the cozy feeling you get sometimes is directly related to the ppm being well over 1000. It affects your thinking, but it creates “atmosphere”. The first 440 ppm you’ll get for free. This used to be lower and has risen steeply in the last 100 years and continues to do so. See the historical graph at https://www.co2levels.org/
people suddenly freaking out, is a cozy atmosphere? Hypercapnia https://en.wikipedia.org/wiki/Hypercapnia
I wanted to express more like the following:
My personal experience is that when the CO2 levels hit over 1200 in a room, it feels more cozy like a bar or crowded place. With all the up and downsides. Would hate to live in a world where this fog is a constant, as it impedes thinking.
