JUSTFACTS attributes MWA for Ocean Acidification Challenges
The JUSTFACTS site reached out to me a short time ago to confirm my work which challenges established ocean scientists regarding the so-called Ocean Acidification phenomenon. I have continued to explore this topic as well, and so we informally collaborated to update my earlier work at  to see if global ocean pH has gone up or down since then.
Here is a link to their ocean acidification discussion: Ocean acidification – Just Facts
I appreciate their uncompromising approach to explore this topic. In my view, the century-long time series of measured ocean pH belongs front and center in any consideration of ocean health. The ongoing omission of this data is a topic which I hope scientists will work much harder to recognize and respond to. That would be preferable to products such as those by the authors of  which continue to promote the notion that oceans are acidifying. Although the Wu et al team  followed my lead  to relate ocean pH to the decadal Pacific temperature patterns, they implied that the instrumental data I spent a few years examining doesn’t exist. In their abstract they stated “Due to limited instrumental measurements and historical pH records in the world’s oceans, seawater pH variability at the decadal and centennial scale remains largely unknown and requires documentation.”
Years before the authors published , I explored correlations related to my paper  between decadal averages of the massive collection of omitted global ocean pH data (GOPpH) and numerous climate indexes. My quantitative exercise (featured in part within the chart below) included a Pacific Oscillation (similar to theirs), an ENSO oscillation (the same as theirs), the Atlantic Multidecadal Oscillation (AMO), a Rocky Mountain river flow record (Otowi gage in NM), Sunspot Numbers (SSN), and the very CO2 parameter of primary interest (MLCO2) to them. ML stands for Mauna Loa, the sole place where global carbon dioxide is indexed to.
The GOPpH significance testing chart below captures some of this work, and shows a strong correspondence of the actual data to the PDO. That makes excellent physical sense to me. In contrast, the inverted magenta cone indicates that there is no significant relation between atmospheric CO2 and instrumentally measured ocean pH. That poses a challenge to any claim of ocean acidification. On the other hand if the real data sets are not recognized, and unreal data are recognized, then the ocean acidification narrative can continue to grow, like a pHonzi scheme I guess.
With regard to the recognition of unreal data, the authors of  do appear to imply that anthropogenic CO2 can actually be mapped across oceans. Yet I can infer from their own references that this is not the case. For example, their study focuses on seawater surrounding a small island, New Caledonia, in the South Pacific. Here is an excerpt from their Figure 1. Note for registration that the north island of New Zealand peaks above the lower border of the frame, and Australia is the large gray mass at the left border.I think it is worth emphasizing that they claim to map anthropogenic CO2 in the oceans. This is especially odd to me at least, because their paper is deeply rooted in isotopic signatures of other compounds. Yet they do not cite any type of stable isotope to explain why the carbon (from the CO2) they map would have purely come from industrial emissions. In fact, no scientist can discriminate “industrial” CO2 from natural CO2.* Accordingly I then reviewed their primary reference for their claim that “.. New Caledonia and the surrounding region of the south-western Pacific are of great interest for investigation because more than 40% of the global anthropogenic CO2 inventory is found in the region between 14°S and 50°S”
It looks as if they cite a paper by Raupach et al.  to support this claim. Yet here is an excerpt from that reference which in fact, repudiates the claim of .This summary chart demonstrates that about 90% of cumulative (Cumul in chart) emissions of industrial CO2 actually originate in the northern hemisphere, and not “between 14°S and 50°S”. I am only one scientist but I think it is also quite a stretch for the authors of  to first disregard all of that instrumental pH data that JUSTFACTS and I have examined, and then to take a paper about emissions sources and transfer 40% of those emissions into a small region of the ocean around New Caledonia. Do I have that right?
I could go on and on about this paper. But if time permitted, I could do so for hundreds if not thousands of actual peer-reviewed ocean acidification publications, each of which deny actual instrumental data and invoke irreproducible data such as this example I’ve extracted from . For my part, I’ll continue to recognize both the instrumental pH data and its high accuracy.
I only have positive things to say about Researchers Will Reynolds and James Agresti at JUSTFACTS. They asked me original and tough questions and I welcomed this chance to demonstrate the transparency and reproducibility of my past ocean pH work. In actually conducting the scientific method by seeking to reproduce the work of another, JUSTFACTS breathed new life into this ocean pH concern. Time will tell if that leads to any improvement for the lay and science communities. For those who would like to join in seeking sunlight, perhaps consider signing this old but still worthy petition.

As this is a blog I don’t mind relating that one journal claimed that the oceans were not buffered solutions in their rejection rationale. 😀
