As if we didn’t already know that it was all wildly overblown. From JoNova:
There goes another scare campaign.
Until recently we had very little data about real time changes in ocean pH around the world. Finally autonomous sensors placed in a variety of ecosystems “from tropical to polar, open-ocean to coastal, kelp forest to coral reef” give us the information we needed.
It turns out that far from being a stable pH, spots all over the world are constantly changing. One spot in the ocean varied by an astonishing 1.4 pH units regularly. All our human emissions are projected by models to change the world’s oceans by about 0.3 pH units over the next 90 years, and that’s referred to as “catastrophic”, yet we now know that fish and some calcifying critters adapt naturally to changes far larger than that every year, sometimes in just a month, and in extreme cases, in just a day.
Data was collected by 15 individual SeaFET sensors in seven types of marine habitats. Four sites were fairly stable (1, which includes the open ocean, and also sites 2,3,4) but most of the rest were highly variable (esp site 15 near Italy and 14 near Mexico) . On a monthly scale the pH varies by 0.024 to 1.430 pH units.
Ocean acidification happens all the time

There’s a nice article on WUWT debunking the ocean acidification hysteria. Like most things on the extremist, Al Gore inspired, alarmist fringe, there’s no there, there.
The Electric Oceanic Acid Test
There is more on the subject on my previous ocean acidification post.

It looks like the next great hoax to follow the global warming scam (and I’m not talking about the .5 to 1.0C that the world may have warmed over the last 100+ years) is ocean acidification.
WUWT has Ocean acidification: the “evil twin of global warming”
The rise in human emissions of carbon dioxide is driving fundamental and dangerous changes in the chemistry and ecosystems of the world’s oceans, international marine scientists warned today.
“Ocean conditions are already more extreme than those experienced by marine organisms and ecosystems for millions of years,” the researchers say in the latest issue of the journal Trends in Ecology and Evolution (TREE).
The report is pretty thoroughly ripped to pieces in the comments. Some of them cal it “grant bait.”
More stuff on “acidification
My view: aince airborne CO2 is trivial compared to oceanic CO2 and since the ocean is a well buffered system and since warming oceans release CO2 and since historic CO2 levels have been far higher with no issues of acid oceans and since oceanic organisms have shown their ability to adapt to higher and lower CO2 I conclude that acidification is a non-issue. More likely the reverse is true, that increased CO2 will be a boon in water as it is on land.

- China Sea pH bounces all over
- SeaFriends site on Acidification – “Alkalinity in the ocean depends substantially on the plankton balance in which the pH results from autotrophs (plants) using hydrogen ions and driving the pH up, while decomposers return hydrogen ions, thus driving the pH down. The daily rhythm can amount to 0.4pH units (250%), and the difference between estuaries and the open sea as much as 1-2 units (1000-10,000%). It is important to keep this in mind, as one can find healthy calcification in shells in these conditions. When seas become eutrophied (overnourished), they also become more acidic due to high levels of decomposing bacteria and their work. Particularly coastal seas show this.”
