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.

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.

Life 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

Its like Somalians in Minnesota, they'd be better off in the ancestral habitat in Africa, but they can survive in Minnesota

There 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.

this, 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

Ocean acidification is exclusively happening in areas where humans are directly dumping nitrogenous wastes into rivers which then flow out to sea.

Every 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."

It is not calling the end of the glaciation the onset. 0 on the X axis is the present day.

Ah, I see. I overlooked that because typically pale blue in such charts is used to denote ice ages. What a bizarre graph.

The 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

Some marine life will already have adaptations which allows it to survive. Thus there is zero problem.

a change between pH of 8 and 6 isn't all that meaningful, both are pretty much neutral.

I 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.

had 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

The 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.

Excessively 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

I 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
