A paper review suggests many studies are flawed, and the effect may not be negative even if it’s real
Howard Browman, a marine scientist for 35 years, has published a review in the ICES Journal of Marine Science of all the papers published on the subject. His verdict could hardly be more damning. The methodology used by the studies was often flawed; contrary studies suggesting that ocean acidification wasn’t a threat had sometimes had difficulty finding a publisher. There was, he said, an ‘inherent bias’ in scientific journals which predisposed them to publish ‘doom and gloom stories’.
Ocean acidification theory appears to have been fatally flawed almost from the start. In 2004, two NOAA scientists, Richard Feely and Christopher Sabine, produced a chart showing a strong correlation between rising atmospheric CO2 levels and falling oceanic pH levels. But then, just over a year ago, Mike Wallace, a hydrologist with 30 years’ experience, noticed while researching his PhD that they had omitted some key information. Their chart only started in 1988 but, as Wallace knew, there were records dating back to at least 100 years before. So why had they ignored the real-world evidence in favour of computer-modelled projections?

Ocean acidification is another often repeated wobbly pillar of climate alarmism.
It's one of the many back up plans to scare the population.
The articles included in this theme issue that report on experiments with multiple variables, and many other such works published elsewhere, confirm that the additional driver(s)—be it temperature, irradiance, salinity, oxygen, nutrients…—typically has a stronger effect than CO2 and that it is difficult to isolate the effect of the individual variables when they are presented simultaneously. Unfortunately, few studies have developed the functional response curves for each variable that would be necessary to more fully assess their individual and interactive effects.
At the time, shipping fuels were largely unregulated in international waters, and typically contained a few percent of sulfur, compared to diesel fuel sold in the US since 2006

I`ll believe in global warming when someone can explain to me how the ice age in north America happened and ended with NO human intervention.
until that can be explained I`ll just assume that hot and cold cycles are a natural occurance and us tiny humans have no ability to cause it or stop it,and while I`m waiting for the explaination please don`t steal money out of my pocket to put in your own pocket in the name of preventing global warming or preventing global ice age.
It's easy enough to desulfur the fuel, and it is an actual pollutant, unlike C02.
What are you in northern Wisconsin? Northern Michigan is always colder then southern. Ice forms on the lakes in the upper peninsula a month sooner then here. No ice fishing the last 2 years on Lake St Clair. Parts of Wisconsin are 600 miles further north. Also lower Michigan is surrounded by water and if the lakes don't freeze it keeps the temps an average 10* warmer then Chicago.

Come to Wisconsin. Ice fishing is colder than in the past. No global warming here.

...which is merely a long-winded way of saying, we can't reasonably asses what's causing it, but we CANT create a science model around CO2 as the master antagonist...or "we know its happening, but dont know why". With that knowledge fully in-hand, it's not alarmism as much as it is ignorance to the real causes which may or may not be naturally occurring.
The correlation was something I found myself by looking at allowable fuel sulfur content by country and then looking at ocean current and ocean acidification maps.
Despite the urgency of the ocean acidification problem, there are few available data sets directly documenting its long-term (decadal to interdecadal) rate or its shorter-term (seasonal to interannual) variability. Repeat hydrography has been used to document a decadal increase in the inventory of DIC in the Pacific (8); however, the technique has not yet been applied to the detection of pH changes. Long-term trends in pCO2oce globally have also been documented from large data synthesis efforts (9), but these results do not directly address pH and are confined to the surface layer.
It is only since the 1990s that it has been possible to discern small pH changes in the ocean with reasonable confidence.
