If ocean acidification is such a terrible problem then why didn't all marine life cease to exist 20 million years ago when oceanic pH was 6?
Oh look, yet another "posting figures but not their source" thread. OP is a faggot
>>16228045>If ocean acidification is such a terrible problem then why didn't all marine life cease to exist 20 million years ago when oceanic pH was 6?The ocean acidification during the Miocene epoch is thought to have occurred at a much slower rate than what we are observing today.Marine life can adapt to gradual changes in pH levels, but the current rate of acidification is rapid, leaving less time for organisms to adapt.
>>16228111additionally, this anon is right OP:>posting figures but not their source
>>16228045>event that caused mass extinctions for both marine and terrestrial animals over the course of 500k years>wHy dIdN'T iT aLL LiFe CeAsE tO eXiSTDumb fuck
>Marine life can't adjust to varying pH levels, evolution is fake. this is what environmentalists actually believe
>>16228045Life evolved in slightly acidic oceans, the creates that currently inhabit the oceans can tolerate alkaline conditions, but they'd be better off with a pH around 6
>>16229853Its like Somalians in Minnesota, they'd be better off in the ancestral habitat in Africa, but they can survive in Minnesota
>>16228045There wasn't even a mass extinction recorded back then. Ocean pH apparently doesn't make much of a difference, the animals in the ocean just live with the slightly varying conditions.
>>16231896this, if ocean ph counted for anything there would have been a massive die off of marine life both 40 million years ago and 10 million years ago, but no evidence of that exists
>>16228045Ocean acidification is exclusively happening in areas where humans are directly dumping nitrogenous wastes into rivers which then flow out to sea.
>>16228045Wait, they want me to believe ocean pH was fucking 6 20kya? Nope. Find a new career path. You're no good at science.
>>16233840>>16228045Also why does this chart show "normal" ocean pH BELOW 8? OP did you make this in MS Paint?
>>16233843Wait that says million. And it's calling the end of the glaciation the onset. This chart just gets worse the more I look at it.
>>16228045>uhhhm if X is bad then why didn't bad things happen when X happened millions of years ago??>ignores the fact that this change in pH took place over millions of years with the pH changing negligibly from year-to-yearEvery fucking time with you retards. You REALLY cannot comprehend the simple idea of "gradual change over hundreds of thousands or millions of years is fine because it gives life time to adapt, sudden change within the span of centuries does not give life time to adapt."
>>16233843>>16233847>I can't read graphsIt is not calling the end of the glaciation the onset. 0 on the X axis is the present day.
>>16233960Ah, I see. I overlooked that because typically pale blue in such charts is used to denote ice ages. What a bizarre graph.
>>16234001The period in pale blue on the chart is noted for being the most recent period with over 0.1% atmospheric concentration of CO2. There were no mass extinctions during that era, according to the fossil record life on Earth was thriving at that time. Primates did especially well during that era
>>16228045Because we need to ban civilization.
>>16228068No, envrionmentalists are, because they want to steal everybody's stuff because they are all communists of some flavor.
>>16228111>Marine life can adapt to gradual changes in pH levelsSome marine life will already have adaptations which allows it to survive. Thus there is zero problem.You will never be justified it taking away peoples rights, scum of the earth.
>>16228698>mass extinctionsNot my problem statist fuckwit. Feel free to keep sea urchins as pets.
>>16228855Environmentalists assert that we must enslave humanity to the government in order to preserve the environment exactly as it is, in spite of change being natural. Oh and in spite of objective morality, because they are statist vermin.
>>16235102Take your NMDA blocker pills, schizo
>>16235098Keeping a pet thats so delicious is challenging. Thats why I have pet ferrets.
>>16234001>blue means cold
>>16228045a change between pH of 8 and 6 isn't all that meaningful, both are pretty much neutral.
>>16238143t. midwit pseud
>>16238143I run a bunch of marine aquarium tanks and the smaller ones have fairly substantial pH swings because I don't have time to monitor them all on daily basis.The creatures in those tanks never seem to notice, their behavior never changes regardless how much the pH moves around.
>>16238802had the same experience in my marine tank, had it all the way up to 8.5 once and its been as low as 7.5. nothing in there ever seems to care
>>16239847The ocean doesn't just have one single pH level throughout the whole system, pH varies regionally and in any location it varies substantially. Tiny fluctuations don't make a difference.
>>16239847Excessively high pH is a lot worse than something like 7.5. You can go all the way down to neutral pH and even below that and none of the creatures will notice the difference. The plants actually prefer pH on the low side, they'll grow fastest at about a pH of 6
>>16235094>people>having rights
>>16240383>The plants actually prefer pH on the low side, they'll grow fastest at about a pH of 6I have enough problems with excess algae growth due to nitrates already, guess I should focus on keeping pH at 8.2. Thinking about getting a sump tank and growing seaweed in there to help remove nitrates
>>16235028>Primates did especially well during that eramore evidence that enhancing atmospheric CO2 content will benefit humanity
>>16229853the plants would be for sure
Who cares. The people too dumb to understand any of the linguistic connotation are helpless just as much.
>>16240127You can literally throw car batteries into the ocean and the fish will swim all around them without ever noticing a thing.
The oceans' pH isn't 8.2, its about 7.5 to about 8.5 at the surface. 8.2 is just the mathematical average. The pH drops by roughly 0.1 every 1000m in depth, so areas with persistent upwellings have lower pH. Claiming the entirety of the oceans are an unvarying 8.2pH is like claiming that the entire Earth 15ºC.
>>16246462>Claiming the entirety of the oceans are an unvarying 8.2pH is like claiming that the entire Earth 15ºC.Dumb people will believe any lies their told by Black Soience Man or Bill Nye on TV. Dumb people are dumb, they do dumb things and have dumb beliefs. Half of all people are below 100IQ
If pH made that big of a difference to marine life it would all die every time it rained on the ocean, since rainwater has a pH of 5-6. Life is robust, it didn't evolve to drop dead every time conditions weren't exactly perfect, it evolved to do the exact opposite of that.
How have horseshoe crabs survived unaltered for over 400million year if oceanic pH shifts are meaningful to marine life?
>>16249660nobody can answer this question
>>16249660The environmentalists' idea that the environment is fragile and needs to preserved under glass in it's present state for eternity is completely at odds with Darwin's theory of evolution.
>>16252186sure, but that idea isn't at odds with their savior complex delusions that justify their megalomaniacal power fantasies
>>16252186environmentalists are extremely uneducated, they never read darwin and they don't understand science
>>16230815We'd all be better off if they were returned to their natural habitat
>>16251141Its because marine life isn't all that sensitive to changes in the pH of their water
>>16248275This, people who believe that slight changes to the environment will make all life die out are evolution deniers
>>16258640Darwin's theory states the environmental change is the driving force behind evolution, so attempting to prevent environmental change is an attempt to halt evolution.
>>16249660they're meaningful mostly to calcium carbonate shell making organisms since lower ph will dissolve their shells more easily.Horseshoe crabs aren't one of those.
>>16259449Taking that into account enviromentalism is just evolution flavored autism
>>16259453It's a nothingburger.200 years of human activity since the industrial revolution has reduced ocean pH from 8.2 to 8.1.Consider picrel. Shelled sea creatures aren't going anywhere.
>>16259525>reduced ocean pH from 8.2 to 8.1.thats only the surface pH and the surface pH has always had a variance of about 0.5
>>16228045There wasn't even a noticeable change in marine life back then. pH shifted from 8 to 6 and back again and it made no difference to anything in the oceans
>>16259525If the pH raised up to a 10 or so, would clams and oysters have shells as hard as diamonds? If we don't stop that from happening, shellfish eaters will start to die out from broken jaws
>>16228045>>16228068>>1622811495% of these threads can be eliminated if OP and other Dunning Kruger idiots took writing 101 and actually learned references exist outside of wikipedia. A semester or two of suffering under APA citation rules is what they need
>>16263762If ocean acidification is such a terrible problem then why didn't all marine life cease to exist 20 million years ago when oceanic pH was 6?
>>16264591Nobody can answer this question
>>16265544> entitlement to anons answering questionsOk, listen here, since even Morgan Freeman’s voice fails to beat sense into your smoothbrained ass. It’s not that oceanic pH went acidic that’s the problem. The problem is that it’s going acidic, while there’s an increase in average sea temperature, a decrease in ice sheets, an increase in mean summer temps, and a decrease in the best carbon sinks we have: forests. All of this shit is happening all at once, and the cumulative effect is what’s causing the planet to go wack.If it was just ocean acidity then there’s nothing to worry about, maybe whales go extinct, too bad. Now, all we can do is watch as the Great Barrier Reef bleaches from all the shit we did.And no, no sources, go to r/collapse or r/collapsescience if you want them. Somehow redditards have more sense than you
>>16266001>it’s going acidicits on average over 8.1 with 90% of measurements falling in the 7.6-8.6 range. its not acidic anywhere except maybe when its raining. if acidity were going to kill marine life then all life in the oceans would die ever time it rained because rainwater has a ph below 6
>>16233839interesting
>>16266001The reefs are recovering tho
>>16267186those few locations are whats dragging the overall averages down, not "global warming" which doesn't even exist
>>16228045Charles Lyell and his ilk just fibbed numbers for his age of the geologic layers, and he's not even remotely right, they can't be millions of years apart because there's no erosion or channeling or formation of lakes between the layers.>>16265544I can, the world didn't exist 20 million years ago. It can't be any older than ~30,000 years because atmospheric C14 hasn't reached equilibrium.If you find a box of coins in a shipwreck underwater, you have to look at the newest coins to get the best guess for when it sank. They've also found soft tissue in dinosaur (a term coined in 1841) fossils, and in fossils in areas where it gets very hot during the day and very cold at night. They can't even consider anything that doesn't align with the millions/billions of years paradigm because it's foundational for their creation myth they call science, it's their whole world view, it's their religion, and they're massive zealots.
>>16268104Right, its just like how they (ab)use the urban heat island effect to create the false impression of warming in global averages
>>16262160lol
>>16228045Nobody is saying acidification will wipe out all undersea life, just that it is damaging to some species, other species like jellyfish are projected to thrive
>>16228111Yeah, in 200 years, the shallow surface seas have decreased from 8.2 pH to 8.1 pH.Just look at this graph of calcium carbonate solubility. >>16259525At this rate of ocean acidification, shelled marine animals only have several hundred thousand years before it becomes impossible for them to create shells!
>>16268133>They've also found soft tissue in dinosaur (a term coined in 1841) fossilsLmao no they fucking haven't. What has been found are fossilised soft tissue structures, but only tiny, usually microscopic segments, because it takes incredibly rare circumstances to produce such fossils.http://palaeo-electronica.org/content/2022/3739-soft-tissues-in-fossil-bone
how does throwing car batteries in the ocean affect this issue?
>>16228045The average envirofag can't tell you. Nor why higher CO2 didn't heat the Earth and runaway turning the entire planet into a Venusian hell. Yet they still think they are 'experts' on how "WE'RE ALL GONNA DIE!" because you didn't recycle a milk carton or some shit.Just like moving entire cities uphill brick-by-brick over a century span would happen naturally, be no big deal, and be way cheaper than whatever bullshit plan they have to stop 'muh rising sea level'. No unmanageable mass migration inland would even be noticeable it would just be a regular part of human and economic activity. More people are mass-migrating away from the coastal states quicker right now ironically over excessive taxation and bullshit environmental regulations from the same faggots peddling this shit, and yet they're not talking about that as if it's any kind of crisis.It's all such politically-driven faggotry and you're right to ask these obvious questions that are obvious. According to these idiots we should be dead a thousand times over from their last failed predictions and brown-paper-bag-huffing panics.
>>16243623Environmentalists are worse than the faggots on /biz/. When 'line go up', it's always going to the moon.Pity these fucking faggots don't feel the same panic when they look at a graph of taxes, increasing horseshit regulations, or government spending.
>>16274350>brown-paper-bag-huffing panics.Hyperventilation is caused by CO2 deficiency
>>16275157Nice. So if we run our SUVs round the clock we'll eventually get these faggots to STFU.
>>16274350Of course we can. Earth is further away from the sun than Venus so more CO2 will have a smaller effect. Go look up "Faint Young Sun Paradox" for how higher CO2 in the atmosphere actually saved our planet from becoming an ice ball.It's fun to watch you guys struggle with basic science because you idiots have never taken Earth Science classes before and think you know shit because you saw a climate denialist blog once.
>>16275188You obviously don't understand Chaos Theory.
>>16275188projection you have never studied this topic past high school and you have no idea what you're talking about
Your graph is in millons of years, brother. There is your answer.
we need to drill some more oil and use that for air conditioners!

If the world is being destroyed by CO2 and women care so much about the environment, why does every woman's dating profile say they "love to travel"?Can't we just ban women "travelling" and save the fuel for necessary business by mostly men and then not have to worry about Climate Change because of all the fuel we'll save?
>>16279686
>>16266001>oh no ice sheets are shrinking during an interglacial period how low does your IQ need to be to expect ice sheets to grow during an interglacial period?
>>16280935Well yes, but anon has a point. Just because it’s interglacial period doesn’t mean we get to do a whole bunch of shit. Ocean acidification is only one of the things we’re doing wrong, and the climate is a chaotic physical system. Meaning it has chaos and sensitivity to changes; displace it from the usual sustaining feedback loops and suddenly we’re out of the “interglacial period” and in the Permian Great Dying within like a century.Or maybe not. I don’t know, go ask the climate scientists. Oh wait, they’re all saying yes. Maybe I should believe them, or maybe just push it off as “narrative”.
>>16280935Extremely low, but half the planet is below 100IQ, which explains why so many people believe in global warming even though there is no evidence of it
>>16281993Only the lowest IQ states have a majority of people who think global warming is real
>>16283276very strong correlation
