I don’t disagree entirely, I do think it important to consider that we as macro fauna are more tolerant to shifts in atmospheric concentrations, but we are dependent on a food web like every other living thing on the planet. The ocean is an enormous food web, and of course I wasn’t there 250 million years ago to witness the Permian extinction, but it seems plausible that volcanic activity caused a crash in oceanic food webs, leading to massive mortality, carcasses sank, methanogenic bacteria in the depths metabolized the nutrients into H2S, poisoning everything that breathes atmosphere. Whew! I keep saltwater aquariums and when H2S starts being produced because of a large death in the tank, you certainly know it. The microbes always react the fastest to environmental changes. I actually found one of those massive arrays while exploring Eastern Oregon one time. It was actually pretty spooky, no one there, but not abandoned either.
Discussion
there's a huge gulf of chemical property differences between hydrogen sulphide and carbon dioxide, or for that matter nitrogen oxide versus nitric oxide versus ammonia
carbon dioxide is not very soluble in water, and even less soluble in brine, and its optimal solubility is achieved at around 4'C and at several atmospheres of pressure
being that the pressure at the surface of contact between the air and the sea is literally one atmosphere (virtually the definition of it) this means that as a gas that modifies sea pH, it has a trivial, trivial trivial contribution to any changes in the sea pH, unless somehow gravity suddenly increased and the pressure increased and it became more soluble, or the temperature dropped to an average of 4'C in the ocean, and somehow the salinity dropped as well
hydrogen sulfide, on the other hand, is far more soluble in sea temperature water at 1 atmosphere, as are many of those nitrogen compounds
methane, also, is highly questionable as a serious danger because, first of all, it tends to rise as it is lower density, and because it is prone to oxidation, it is prone to converting into CO2 once it gets into the UV and ionising radiation regions in the upper atmosphere like the ionosphere, which is well above the part where total internal reflection causes the greenhouse effect
further, CO2 is heavier than air, so as soon as that methane rises and bumps into O3 and reacts due to some additional IR, the reaction product is 2x H2O and 1x CO2
Water is the most potent greenhouse gas, far beyond any of the others, because it has the highest latent heat capacity, and that property is predicated upon its capacity to form hydrogen bonds with itself, which we see as surface tension in the liquid phase, and refraction in the gas
methane combustion produces twice as much water as CO2, but that's a bit inconvenient for the climate cult because water also stabilises temperature, as it holds huge amounts of thermal energy in its orbit, and thus naturally reaches an equilibrium in the atmosphere that combined with sufficient atmospheric volume and magnetic field from the core of the planet protects us from radiation and enables us to live long enough without mutations to our stem cells that large life forms can flourish on the surface
every sign we see around us suggests that the planet is highly metastable and that only large external influences can cause catastrophes, such as comet and meteor strikes, solar fluctuations and gravity effects from alignments of orbits
humans are also a tiny fraction of life on this planet, indeed within our bodies our cells aren't even the majority!
all this doomsday shit is just by way of convincing people to tolerate the impoverishment of devaluation of their money, and that's why Bitcoin is so important
Your knowledge is impressive, I don’t see the relevance to the point I was making however. You are certainly entitled to your opinion, to me it’s like saying that we could mine all the arsenic or uranium in the earth’s crust, aerosolize it into the atmosphere and have there be no lasting effects for life on this planet. We can agree to disagree, it’s cool. I still really enjoy the discourse. I still vacation in tropical locations. 🤘🏻😊
