Atmospheric CO2 is on a trajectory to reach 550-600 ppmv by the end of this century. There is no scientific basis to assert that this will drop the average pH of he open ocean from 8.1 to less than 7.5. Atmospheric CO2 would have to rise to 1,000 to 2,000 ppmv to drive average seawater pH below 7.5.

there are 350,000,000 cubic miles of ocean water. CO2 as a percent of the atmosphere has increased 1/10,000th as a percentage of the atmosphere in the past century and one-half. The temperature of the ocean averages 39 deg F. Global temperatures were often warmer than today in the prior 9,000 years of the Holocene, obviously caused by natural forces and not CO2. CO2 levels are, today, among the lowest level in the history of Earth, i.e. CO2 levels were as much as 17 times greater in 85% of the past 600 million years. Levels were 500% higher in the age of the dinosaurs. Thus, we should not expect a lot of trouble from the oceans, didnt happen in the past, so why would it now? CO2 is absorbed by living organisms in the ocean, when they die they fall to the bottom of the ocean. Limestone is simply sequestered CO2 from this process.

We acknowledge that seawater is basic and cannot truly acidify (pH<7). The generally accepted linguistic convention—for better or worse–is that lowering seawater pH means ‘acidification’. There is no doubt that adding dissolved CO₂ does lower pH. The relevant questions are how much and whether that amount matters.

There are certainly some ocean related AGW consequences beyond any scientific doubt. Henry’s Law requires that the partial pressures of atmospheric and dissolved ocean CO₂ equilibrate. Rising atmospheric CO₂ must increase dissolved seawater CO₂. That is long established simple physical chemistry.

First and foremost, ocean pH is not a linear chemical system driven only by Henry’s law; it is a system highly buffered by dissolved minerals and seafloor carbonates. Taking seawater chemical buffering into account, IPCC AR5 3.8.2 suggested that doubled atmospheric CO₂ might cause surface pH to decline by Δ0.15-0.2. This is well within the normal diurnal and seasonal biological seawater pH variation for almost all ocean waters. It is no cause for the alarms sounded.

How marine creatures do under experimental aquarium conditions of roughly doubled CO₂ (with food, light, and temperature held constant) depends on species. [ii] Crustaceans, temperate urchins, calcifying (coralline) algae, limpets, and mussels do well. Oysters, conch, bay scallops, and some tropical corals don’t. But aquariums do not reflect the important interplay of many other ecosystem factors also affecting these creatures. Nature demonstrates the enormous variability and resilience of actual marine ecosystem biodiversity.

An example of the unfounded alarm described above was the recent reporting that rising acidity posed impending danger to Dungeness crabs. According to the Guardian, the “Pacific Ocean is becoming so acidic it is starting to dissolve the shells of a key species of crab.” A little research showed just how utterly false claims such as this are. According to the Food and Agriculture Organization of the UN, Dungeness crab must not have gotten the message about their imminent demise because their numbers are thriving and getting better (Figure 24). The most recent reporting year was the 7th highest since 1950.
