As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years - from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930. However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!! By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8. Indeed the daily noted maximum pH range of 0.7 (Santos et al. 2011) is far greater than the overall change predicted between now and the end of the century.
Capturing CO2 is a mathematical problem as much as it is a chemical process and an engineering megaproject. It's all about scalability. We can attack the problem from many small points while working on any sure-fire means of correcting it. I've hypothesized that it can be done without using chemical processes. I've researched how and calculated it would meet the IPCC requirements of by 2100. Would anyone like to know how?
As a Kid I always wondered why we had the story of King Canute .

It would also have a minimal environmental impact. As well as a means of desalinization.
Applying the "ante-acid" process you're talking about, it would be a home run.

While you're having a closer look, I'm watching the biosphere collapse. Take your time!
😅NOAA is as usual totally clueless about the health of the world’s oceans
