Same. And logarithmic scales are kinda unintuitive. But for comparison: "...in humans, arterial blood pH normally falls within the range 7.35-7.45. A drop of 0.1 pH units in human blood pH can result in rather profound health consequences, including seizures, heart arrhythmia, or even coma (a process called acidosis). Similarly, many marine organisms are very sensitive to either direct or indirect effects of the change in acidity (or H+ concentration) in the marine environment. Fundamental physiological processes such as respiration, calcification (shell/skeleton building), photosynthesis, and reproduction have been shown to respond to the magnitude of changes in CO2 concentrations in seawater, along with the resultant changes in pH and carbonate ion concentrations that are expected over the next century."

You've probably done your report, but I hope you asked some questions. For example, at 3:07 it says in 1751 the pH was 8.25 ( the IPCC says 8.2). Where does this come from? Did someone go back in a time machine with a digital pH meter? They didn't even know what pH was until the early 1900s. This is based on computer models and not reality. The oceans have a lot of problems but becoming 'more acidic' is not one of them. The sea is alkaline and always will be.

Excellent explanation. Thanks for putting this together.

Calling it "acidification" is like calling eating a little less, "starvation." And on top of this insanity, the psychopathic globalists are promoting fear of warmth in an ongoing Ice Age.

But please do tell me how there are no measurements of the ph of the occean... Here is a sample of hundred of values which is still just a drop in an ocean of data: www.epa.gov/sites/production/files/2016-08/ocean-acidity_fig-1.csv Here's some more: www.pmel.noaa.gov/co2/map/text "all alkaline and not acid!" No one is saying that the oceans are acid. The oceans becoming are more acidic. "Calling it "acidification" ..." it's like saying little Tim is taller now (although Tim is still a child and not tall). That is standard in the English language. It is also standard in the English language that a shift towards acidity is called acidification and a shift towards basicity is called basification. But you can also call it less basification and less acidification (but that doesn't sound right - a bit like calling eating "less starvation"). And again, like your idiosyncrasies your semantics and wording is also irrelevant to the facts that the ocean is in fact less basic/more acidic (regardless of however you want to call it - cause rewording your sentences will not make reality any different). You (and other denialists like you) are after all, the one who is insane or unethical, or both. You are the psychopathic ignoramus propagating the misinformation about the impact of modern practices on climate. "an ongoing Ice Age" - Because change over hundreds of thousands of years is totally the same thing (and totally gives the same time for ecosystems to adapt) as rapid change in less of a thousandth of the time of the time. There is no excuse for your ignorance nor shameless behavior.

You truly the best hats off

What I don’t get is you say that HCO3 dissolves in H+ and CO3 thus causing acidification because of H+ release then argue mollusks don’t have as much access to CO3- because it combines to the H+ in the water ? Which is it then ? Is that H+ running around causing acidification or is it combining with the CO3 preventing mollusks from using it ? And if it is not combining with the CO3, then the mollusks should be getting more CO3, not less ? This is confusing.

Does that mean adding bleach and baking soda into the ocean helps balance the acidity level in the ocean?

Not enough people are talking about ocean acidification 😭

The ocean like blood has a natural buffer (Carbonic acid/bicarbonate) system . It is not mentioned here. The assumption of your model leaves that important factor out.

Are there any plants or any sea life humans can step in and help encourage faster growth to fix problems our earth has?

At lower pH values, bicarbonate concentrations dominate, and large concentrations of carbonate ions will protonate to form bicarbonate. Concentration of carbonate ions decreases with lower pH values. You do have a point in saying that adding carbon dioxide will increase carbonate concentration, but this would also reduce the pH of the water, which in turn makes it favourable for carbonate ions to protonate and form bicarbonates, thus reducing the carbonate concentration, in spite of addition of CO2.

1 molecule of CO2 with 1 molecule of H2O produces 1 molecule of the acid, H2CO3. Now here comes the tricky part: that 1 acid molecule of H2CO3 can give away 2 (!) H+ to form 1 carbonate CO3(2-). Now one of these H+ can catch up with the original CO3(2-) to form that intermediate product, bicarbonate HCO3(1-), BUT the other H+ can now (instead of also going back to the original molecule and go back to the acid H2CO3) grab one additional CO3(2-) from the poor shells who actually wanted to make it into calcium carbonate - Boom, one carbonate lost for the shells for each CO2 dissolved, and the ocean richer in HCO3(1-) instead of calcium carbonate shelly creatures. So the problem seem to be the two acidifying H+, which come with each one CO2... Also, I guess the levels of H+ and carbonate, CO3(2-), are increasing as compared to the calcium, Ca(2+), which might be a problem?

I don't understand that on the one hand you say that the absorption of co2 leads to the production of carbonates (which would be beneficial to create calciumcarbonate for animal skeletons) and on the other hand you say it' a problem that calciumcarbonate cannot be formed due to the high levels of h+ in the water. But by absorbing the co2 both ions are formed. So if no co2 would be absorbed, the acidity might not increase, but there would be no increase in the amount of carbonate ions either. (?) So based on this video, the positive effect of adding carbonates would be compensated by the negative effect of acidification, meaning no overall change. Where would the carbonates that they need so much otherwise come from? Please help me on this one.

@@catherinegalindo22 Check the dissociation constant on H2CO3. It is such a weak acid that It will probably never go to CO3(2-) by itself, and only some of it will go to HCO3-. In order to keep dissociating it needs to be spent. Further increase in concentration of H2CO3 in the oceans will not result in proportional increase in available H+ ions. There will be more available H2CO3 for "spending" and reacting, but that's not really going to affect the organisms proportionally to the increase in H2CO3, because chemistry of living organisms is not the same as chemistry in a laboratory glass with reactants that have tension between them caused by the difference in reduction potentials, as their (living organisms) reactions depend on pH rather than the concentration of the weak acid that is present around them. Living organisms can utilize energy to force the "natural" reaction go backwards and they will not obey the standard laws stoichiometry.

@John Gregg Calcium is a very abundant metal on the Earth. It was simply there. But since it's extremely reactive, it mostly forms calcium hydroxide (very alkaline salt) in contact with water. Calcium hydroxide is very soluble and dissociates into ions, which makes it available to living organisms, and it can also react with acids to form different salts. Organisms are usually responsible for turning Calcium salts into less soluble Calcium Oxide (shell material), which then creates sediments and rocks.

As more and more research is conducted, it becomes increasingly clear that the effects of ocean acidification on ecosystems and individual species is very complex. A laboratory study on blue crabs, for example, shows that their shells actually get thicker in more acidic conditions. However their prey is clams and the clams shells dissolve. A lovely, thick shell does not help a crab if he is starving. See: www.chesapeakequarterly.net/V11N1/main3/ This is just one of the thousands of negative interactions that will result from a sustained change in ocean pH which will change entire ecosystems and cause the rise of some species- predominantly jellyfish while causing the ultimate extinction of others such as dolphins due to loss of prey. For a fascinating and highly disturbing look at the future of our oceans read Lisa-ann Gershwin's 2014 book, "Stung".

Dangerous drivel. 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.

Sea water PH is 8.3 on average. With the amount of salt in the ocean it absolutely cannot become acidic. CO2 doesn't remove the salinity, this is smoke and mirrors. Shallow coral reefs are often rained upon and it lowers the PH, but doesn't harm the corals or the foraminifera. The ocean is not becoming acidic and it cannot. I'm an Aquariologist and what harms corals is pollution. The coral reefs off New Guinea Island is much warmer than the Great Barrier Reef of Australia and don't suffer from bleaching, so it's not heat that causes it, it's pollution. Fix that and the bleaching will stop.

Mountain Fisher - your adamant belief that the pH of the ocean cannot change is both touching and alarming. Touching as it appears that you truly do care about the oceans and do not want it to be true that the pH can change. You don't want it to be true that the oceans have reached their capability to absorb safely the carbon dioxide that falls into them. The alarming part here is that because you don't want it to be true, you will therefore not be doing anything to change humankind's behavior. Unless and until you understand what is happening under the water. Flatly, sadly, you are wrong that the pH can't change. Current research absolutely proves that not only can the pH of salt water change when overloaded with carbon dioxide, but that indeed it is. Read the IPCC reports and other recent research in which scientists measure the changes in pH. The seemingly tiny, tiny changes pH have huge ramifications for the species that have very low tolerances for changes in pH. The changes favor the species that are tolerant- like jellyfish - and they will take over when the less tolerant species decline on their way to extinction. Eventually the apex species like dolphins, whales, sharks, etc will go extinct do to lack of food. We will notice them. But lost to posterity will be the thousands of unnamed, unknown demersal species that are the base of the ocean food chains. Sad.
