Analysis of Alarmism: Ocean Acidification  by Dr. Tim Ball


A Neutral View of Oceanic pH

Fraud in the popularly used Acid data?





Ocean Acidification Will not Kill Coral Reefs and Shellfish by Patrick Moore


There is a recent and interesting study in GRL ... This study reports on the change in ocean alkalinity over a 15 year period (1991-2006) along a transect of the North Pacific from Hawaii to Alaska.... when you go from the tropics (Hawaii) to the North Pacific (Alaska), the water becomes less and less alkaline. Who knew? So even without any CO2, if you want to experience “acidification” of the ocean water, just go from Hawaii to Alaska


The result was a big increase in acidity—to levels higher than have been predicted for the future due to human emissions—yet, the coral continued to flourish.     (local)  (Be sure to follow the links to other articles on this site)



Coastal Ocean Acidification: Answering the Seattle Times


           The Seattle Times emphasized the “lethal” waters that were killing shellfish, particularly oyster larvae.  But the truth is that native shellfish species living in our waters have been doing fine.  In fact, even non-native species growing in our natural aquatic environment have been doing well.    


The problem was limited to factory aquaculture of non-native species.   Or to put it more exactly, limited to big tanks containing oyster larvae of non-native Pacific oysters from Japan.  Oyster larvae that could not reproduce in our cold waters, with or without any extra CO2.  The problems only occurred in these oyster larvae factories during short periods during summer when there was strong upwelling of coastal waters-when cold, high-CO2 waters located at depth were lifted towards the surface as a result of stronger than usual northerly winds.  


Ocean Acidification — a little bit less alkalinity could be a good thing

In Brief: The oceans are not acidic, and will not become acidic in the foreseeable future. Many of the fears and alarming scenarios are based on models. Many scary headlines are based on studies of extreme pH values beyond the range of anything realistic.


Incredibly, hundreds of studies show that for pH changes that we are likely to encounter in the next 100 years, there is arguably a net benefit to underwater life if the oceans became a little less alkaline.




Scripps blockbuster: Ocean acidification happens all the time — naturally

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


Failing the Acid Test – Jane Lubchenco


So the basis of all the hype is a calculation from an estimate, which gives a precise figure of 0.1 pH decrease, they don’t even know the consequences of changes in pH, and the conclusions they reach are based on an extrapolation of eighteen years of data from one Pacific ocean station, to 2100 and 2300




4. IPCC WGI state that the mean pH of surface waters ranges between 7.9 and 8.3 in the open ocean, so the ocean remains alkaline. It is dishonest to present to a lay audience that any perceived reduction in alkalinity means the oceans are turning to acid.


5. The claim that “ocean acidity” has increased by 30% since before the industrial revolution was calculated from the estimated uptake of anthropogenic carbon between 1750 and 1994, which shows a decrease in alkalinity of 0.1 pH unit, well within the range quoted by IPCC.


9. There are many contrary peer reviewed papers challenging the claims about the impact of CO2 on the oceans. One survey highlights some one hundred and fifty such papers, most of them showing that we cannot possibly acidify the oceans. The IPCC claims to present the physical science basis for IPCC claims


Dying Shell Fish Larvae: A Distorted View


Prominent scientists have claimed that high mortality rates in Oyster hatcheries  operated in the North West Pacific, are due to “acid seawater” resulting from upwelling of the deep ocean. There is no acid seawater. As stated in AR4 WGI, the oceans are alkaline, not acid.


Those same scientists stated that bacterial contamination of seawater was not to blame for the high oyster larvae mortality rates.

Contrary to their false claims, the problem of early oyster mortality has been found to be directly caused by a faecal organism, Vibrio tubiashii. Research programs are currently underway to investigate the extent and resolution of the problem.


This research is being conducted by the Pacific Shellfish Institute and was known at the time of the acid seawater claims.

The fact that this was not considered or was even ignored, when the claims of “acid seas damage” were made, is at worst, mischievous and at best, very un-scientific.










Why Ocean Acidification Is A False Alarm
AcidGate–-Why Acidification appears to be a fraud based on computer created historical data instead of actual data.

“In whose professional world,” Wallace asks, “is it acceptable to omit the majority of the data and also to not disclose the omission to any other soul or Congressional body?”

Feely, and his coauthor Dr. Christopher L. Sabine, PMEL Director, omitted 80 years of data, which incorporate more than 2 million records of ocean pH levels.

Feely’s chart, first mentioned, begins in 1988—which is surprising as instrumental ocean pH data has been measured for more than 100 years since the invention of the glass electrode pH (GEPH) meter. As a hydrologist, Wallace was aware of GEPH’s history and found it odd that the Feely/Sabine work omitted it. He went to the source. The NOAA paper with the chart beginning in 1850 lists Dave Bard, with Pew Charitable Trust, as the contact.
Wallace asked again for the “time series data (NOT MODELING) of ocean pH for 20th century.” Sabine responded by saying that it was inappropriate for Wallace to question their “motives or quality of our science,” adding that if he continued in this manner, “you will not last long in your career.”
Interestingly, in this same general timeframe, NOAA reissued its World Ocean Database. Wallace was then able to extract the instrumental records he sought and turned the GEPH data into a meaningful time series chart, which reveals that the oceans are not acidifying. (For another day, Wallace found that the levels coincide with the Pacific Decadal Oscillation.) As Wallace emphasized: “there is no global acidification trend.”

Basics of Ocean Acidification  (local) The oceans are buffered by extensive mineral deposits and will never become acidic. Marine life is well-adapted to the fluctuations in pH that occur all the time.
This is another example of climate fear-mongering:  It never happened before, it’s not happening now, but it surely will happen if we don’t DO SOMETHING!.
