Interesting but I am now boating in lake Huron. As everyone knows acid actually keep aluminum from coroding and because Huron is not sitting in lime stone so the PH has always been just above neutral. Buts this year the aluminum parts of my engine that sit in the water have all corroded so our lakes are getting more basic!

He is wrong... Carbon Dioxide In water largely stays as CO2. Only about 1% actually contributes to creation of carbonic acid. Carbon Dioxide will never acidify the oceans, it will be alkaline for quite some time.

[@CopingsCorner]

This is problem cannot be overestimated. I addressed that even though we could hypothetically build orbital solar shades to cool down the planet (implicit ofc solar dimming), this would not prevent ocean acidification, and so CO2 has to be dealt with regardless.

If anyone is wondering how does more CO2 mean less CO3 when it's the final result of the equation, you have to remember that CO3 plays a role in the buffer system, and along with H+ will give HCO3. That means the more CO2 you add, you will also be losing more CO3 in favor of HCO3. Hope this is helpful.

[@dismantledbrain5910]

@@LawsonR I haven't noticed your comment the last time I've commented on here, but for those who might be confused about the same thing, he explains it at 0:58. CO2 is going to force the hydrogen out of other compounds, thus creating more H+ in the water.

Increased carbon dioxide will lead to increased surface temperature which decreases solubility of carbon dioxide on oceans, so I believe we are missing pieces here, and saying CO2 decreases alone are a solution is reductionist, I'd imagine

"This is often termed “ocean acidification” because it describes the process of decreasing pH. Current projections of ocean acidification suggest that the pH of surface ocean waters will continue to decline. However, the term can also lead to confusion when it is wrongly assumed that the oceans will become acidic, when in reality, ocean pH is never expected to fall below 7.0; i.e., the oceans are becoming less basic, but not acidic. Such a phenomenon could only occur in the unlikely event that CO2 emissions reach more than 10,000 Pg C (Caldeira and Wickett, 2005)"

[@climatedeceptionnetwork4122]

That's good. I think I understand. "Less Basic" is the phrase, not the word "acidic."

[@ZaphodBeeb1]

Decreasing pH means the oceans are becoming less basic - that's a fair description. But before the oceans start to become acidic they have to pass through pH 7.0 - which is neutral, as is pure water. Therefore, the oceans are neutralizing which is not the same as acidifying. The term acidification is used because it is more likely to catch the attention of, or alarm the general public. Some may say that this term is used with "good intentions", because they believe that prompt action is required. But it's misleading and an exaggeration.

Clarification question: In the Bjerrum graph, it depicts Carbonic acid at its peak when oceans are more acidic, and carbonate when oceans are more basic. However if it's an increase in H+ ions that causes oceans to become more acidic, should we get an very acidic ocean when carbonate is at its peak, rather than carbonic acid? I would have thought that lots of carbonate means lots of dissociated H+ ions floating around making the ocean more acidic. I'm sure I'm just missing something here. Thanks, great video!

[@mathchemboss7487]

I have 2 remarks. I have seen this graph in textbooks, but then different. Then CO2 and HCO3 concentrations are equal at pH 6.5 , HCO3 and CO3 are equal at pH10.5. This is also the case if I make the calculus, with the help of Ka (the acid constant). This means your graph is wrong (or do you have another explanation?) Second is this, if the concentration of CO2 increases in the oceanwater, doesn't that mean that the concentration of CO3 also gets larger (equilibriumtheory) ? So where is the problem for the carbonate needing organism? They would thrive!

[@OldScientist]

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 is decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8.

[@Louis6439]

Three relevant points: 1. The pH scale was created in 1909 by Danish chemist S. P. L. Sørensen. We have no idea of the pH of the oceans in 1751. 2. The solubility of CO2 in water is strictly/rigidly controlled by temperature. Cold water holds 5x as much as warm. Our cold oceans (from the last ice age) are saturated with CO2, and are gradually releasing it as they warm. This is the primary cause of rising CO2 levels today. 3. Human activities only account for ~3.6% of the total amount of CO2 released annually.

[@bradkeen1973]

The pH of the oceans in 1751 was 8.25? How do you know that? The concept of pH wasn't discovered till 1909 and reliable testing till 1924. Trouble is that pH can only be measured in real time. Second, the solubility of CO2 in water decreases as water temp increases. To take his soda stream experiment, chilled water keeps bubbles longer. Third, the experiments you see with sea shells disolving in water don't tell you one thing. They adjust pH down by adding hydrochloric acid. Of course sea life and this chlorine compound don't mix.

[@IrishBog]

And the phrase around 2:30 “as we play these models out into the future” And it looks like it’s the same as me saying “At 1 I was 60cm tall - at 50 I was 1.8m tall. So at 100 I guess I’ll be 3m tall”

[@JamalMunshi]

The ocean ph does decrease but not all the way down to 7. tambonthongchai.com/2019/12/14/ocean-acidification-2019/

[@midosabbagh]

The same way we can estimate temps and atmospheric composition thousands and even millions of years back. Ice cores, fossil records and the such. Secondly, yes temperature plays a role but so does pressure. So as pressure rises that helps the carbon stay in solution. Thirdly, you're assuming pH and temp rise at the same rates which they do not. Co2 is entering the ocean faster than temps are raising so your whole theory there isn't debunking much. Also, you have literally 0 proof that the water is cooled so.... Lastly, pH is dependent on number of H+ ions so it doesn't matter what kind of acid you use as long you reach the pH you want to test. Just because high temp slows co2 dissolving into the ocean that doesn't mean the amount in the ocean at that point isn't already causing damage. you can talk about hcl all you want but the fact is Coral is dying and marine shells are weakening already. That's happening now, meaning you cannot deny it.

[@ZaphodBeeb1]

@Dallas Simmons. "Too fast for life to adjust". This is nonsense ! Life is able to adjust very rapidly when it has to and we are all aware of this. We know that rats have repeatedly evolved resistance to anti-coagulants and mice are doing the same. Crop pests evolve resistance to new insecticides in a decade or less. Weeds in our gardens and fields have evolved resistance to dozens of herbicides. Microbes are evolving resistance to antibiotics so fast we can't produce new ones quickly enough. In places which are heavily fished, fish have become smaller, breed earlier and escape through the mesh of the net. Sure, we don't want smaller fish, but nature has acted rapidly. Nature doesn't need 1 million years to adjust, that's what they thought back in the 1850's.

[@santumos]

I have a correction/disagreement with the second part of the video (involving shells and carbonate) If the ocean was getting more acidic by direclty adding H ions in the form of an strong acid (ex. HCl), then it is very clear that the carbonate system would shift, and CO3 would get consumed and less available for shell formation. Similarly, this video makes the audience believe that over time, CO3 in the ocean decreases because of the pH is going down (acidic). However in our case, the ocean is getting more acidic by a CO2 input that reacts with water to form carbonic acid H2CO3. This H2CO3 dissolves to form more H ions, and in the process is also forming more bicarbonate (HCO3) and carbonate (CO3). So *the CO3 concentration does not technically decrease*, (if anything increases). Its concentration gets smaller only relative to the other carbonate species (H2CO3 and HCO3, which are now much much higher than before). The bottom line is, a shell in our acidified ocean is not techincally exposed to less CO3, but instead exposed to an excess of hydrogen ions and a H2CO3-dominated medium that pressures the shell into dissolving quicker to match its medium.

[@Francesco-qr6mu]

Something related the kinetic of the process and also pressure and water temperature in the water column should be discussed, but this cannot be 7 minutes video..

[@adamrichey6021]

I don't understand, if the shellfish are taking more carbonate out of the water to build shells, shouldn't that also mean more hydrogen ions are released, as there is less carbonate for them to bond with to form bicarbonate? It seems like more shellfish = more hydrogen ions, which then means less carbonate, and then less successful shellfish?

Why don't they drop ground basalt into the oceans. That would have dissolved co2 form bicarbonate, which is the main limiting factor how much co2 the oceans can absorb. Also taking care of ocean acidity. Of course that makes more sense after we stop burning fuels which is the fastest way to stop co2. Not sure if it's feasible and how much would be needed. I just realized that probably means just fertilizing the ocean with iron would be mainly for cloud cover generation via dsm (which would have immediate impacts though), rather than for sequestering much more carbon: plankton shells would bind the dissolved carbon, but it won't change the ocean acidity balance or draw more co2 from the atmosphere, for that you need bicarbs from basalt.

[@ZaphodBeeb1]

The whole system is reversible in its stages and is therefore an effective buffer. It will become more and more difficult for the pH to fall. AT 3.40 the presenter says that the bicarbonate level will increase as the carbonate falls. But that increases the pH because the bicarbonate requires an H+. It's self correcting. However, it was misleading to say that the bicarbonate was increasing, because the Bjerrum plot he is using shows the bicarbonate to be levelling off. If the pH goes lower than 7 (acid territory) the bicarbonate decreases as it reverses back to CO2, which would be driven off. So the pH would rise again. The oceans are not going to become acid. The initial experiment of blasting CO2 into distilled water is irrelevant and alarmist.

[@starleyshelton2245]

Simple issue. When water gets warmer it LOSES CO2. When it gets colder it holds MORE CO2. And since warming should cause increased CO2 release from the ocean for a loss and an increase in the air, it seems it would make the water LESS acidic. Warming cannot be enhanced by CO2 release into the atmosphere from the ocean and increase acidification which would require taking in CO2. Decide. Is the ocean getting more or less CO2. One or the other. Because the saturation point of how much the ocean can hold decreases with every degree of warming. Last, the ph of the oceans routinely varies from ph 7.8 to 8.2 which is alkaline, not acidic. We are well within the normal range or variance at ph 8.1. There is no indication that it is leaving this range. I mean even purified water is 7.0 and that is not acidic either. You know fresh water is much lower ph or using their terms, more "ACID", and it is not killing off or dissolving fresh water shelled animals or mullusks. Acidity is normally considered at around 6.0 or below and we are nowhere near that. The SCIENCE does not make sense.
