I'm confused on the part of "if the ion concentration decreases, the poles and the equator could be uninhabitable". But in your diagram (at 2:24) you show that the polar ice caps would increase - which would increase the ion density... right? So wouldn't it be a self-regulating system?

[@MinuteEarth]

@@coolmandan0303 Historically, this sort of thing can cause ice ages that last thousands of years before everything regulates back to "normal" or a new normal at least. Essentially, the world could become uninhabitable for most of life as it exists now for long enough to cause mass extinctions.

[@MinuteEarth]

This is definitely a possibility! The science of what could happen is really complicated because there are so many interrelated processes, but what you’re describing has happened in Earth’s history, called Dansgaard-Oeschger events, where the Earth bounced between periods of warming and cooling. Unfortunately while the warming effects that melt the ice can happen as quickly as decades, the freezing “Ice Age” periods can (and have) lasted hundreds or thousands of years. Several mass extinctions are at least partly attributed to slowing/stopping of currents that left the oceans low in nutrients and oxygen.

*clears throat* the ocean currents are mostly driven be temperature, salinity is just an additional factor. if this video were accurate about the effects of climate change on the ocean, there would be _no life at all_. all the co2 being dumped into the atmosphere, originally came from the atmosphere. sure, we get some bonus carbon from volcanoes, but they are not a significant source of it at this point in geological history. all the co2 from fossil fuels was in the carbon cycle when life was young. and actually much more that is currently locked in sedimentary and metamorphic rock. the vast majority of the earth's life, it had _no ice caps whatsoever_ yet the oceans have always had plenty of life in them. while the physics in this video are fascinating, and it is an important thing to watch in our ocean, this video is the sort of thing that makes people think climate change is a hoax, because it's so obviously not entirely honest.

[@Redingold]

This nitpicky pedantic title isn't even accurate. Chemical equilibrium occurs when the forwards and backwards reactions occur at the same rate. The backwards reactions, of ions forming into salt, still occurs in saltwater, you even show it happening to demonstrate crystallisation of salt in the Dead Sea. This still happens in seawater, it just gets cancelled out by the immediate dissolution of those salt molecules back into ions, but those salt molecules are still forming and are still there, in at least some concentration, at all times. You might as well say that water doesn't actually contain water, because what happens is the H2O molecules self-ionise into hydronium and hydroxide ions. It would not only be stupid to say that, it would also be wrong, because the reverse happens too, where hydroxide and hydronium ions react to form H2O molecules, so there's always at least some H2O molecules present. The salt thing is wrong for the exact same reason.

[@schuldigom]

So the bus does actually have salt? Fascinating

[@BioTechproject27]

And even if we were to ignore this rejoining of ions, we still have large salt crystals everywhere.

Carbon footprints are a way to shift the conversation away from social change and put responsibility on individuals. Some parts of climate change we can control, but collective action is more important

[@romanski5811]

Agreed. There needs to be an appropriate carbon price attached to production. But simultaneously the poorest people (bottom 80 %) need to be given something like a climate dividend proportionally such that they can still afford to live. And also, things like public transportation and renewable energy grid needs to be expanded.

pretty disappointed by the semantics/ bait. why not go further and say there are no sodium or chloride ions there as well, because technically it's only hydrate complexes. and technically, water is not H2O but only mostly H2O as well as complexed autoprotolysis products. we could go on forever but what's the point...

Whilst I agree wholeheartedly that we need to do something about the climate. I do have an interesting question. If the salinity is reduced due to the ice caps melting, would the resulting extreme cold temperature at the poles result in the refreezing of seawater there? Maybe it would self regulate.

[@jasonreed7522]

Yes and no, meaning yes the loss if the currents delivering heat would result in the poles cooling and potentially refreezing/restarting the currents. But No it won't self regulate forever, as evidenced by the earth having periods of 0 permanent ice in the past, and even an iceage happening because of duckweed growing on the surface of the arctic ocean. (Tldr of that, the ocean was mostly cut off from the rest of the sea sorta like the black sea today, so it was super salty from evaporation but rivers flowing into it creates a layer of freshwater a few inches deep on the surface that the duckweed grew in but O2 couldn't penetrate, and give that a few million years and a bunch of carbon was transported to the ocean floor causing an iceage)

Minor technicality: the salt in the ocean is not in its liquid form, it is in its disolved or aqueous state. In chemical equations the phase of thingsa are notated as: Gas (g) Liquid (l) Solid (s) Aqueous (aq) The difference does mater because liquid or molten salt is very hot as ionic bonds are very strong and require alot of energy to loosen up into a liquid (table salt melts at 1474°F = 801°C).

At first I thought the salinity of seawater would continue to increase over time. And imagine that living creatures millions of years ago could drink fresh seawater. 🤔 Now I just found out that the salinity concentration will continue to stay at that point if the marine conveyor belt remains. 😲

Fine then, take an amino acid and put it in water. Each molecule is it's own salt even when dissolved, since it has both a positive and negative charge at neutral pH.

[@BigBoiRedFrog]

Thanks for the information and same

[@davehumphries]

Do all salts taste salty? Can one salt taste more salty than another salt? What is the saltiest salt.

[@MinuteEarth]

Not at all, salts cover the entire range of flavor depending on their combination of ions. Sweet salt, sour salt, bitter salt, etc.

[@kennyholmes5196]

@@MinuteEarth IIRC, salts don't even have to be monatomic ions, just a positive ion and a negative ion combined together, regardless of size.

[@CaptainObvious0000]

salts are ionic compounds, i.e. defined as such only by charge distribution and interparticle forces. this categorization is extremely broad and can cover almost anything. you can ionize a lot of compounds that are not ionic compounds by themselves. the larger the molecules, the less of a role will a single introduced charge play for the interaction with your receptors. pretty sure that for almost anything humans can taste, you could make or find a salt that has that exact taste.

If pole gonna get cold and equators going to be hot again isn’t it gonna start the circulation of water again?

[@PickPig]

yeah! and this isnt a video, its just a collection of frames played at regular intervals

[@MinuteEarth]

I guess you could say salt dissolving in water is like exporting a video as a series of jpegs.

[@eudaimoniaseeker4742]

does it mean, salt just an ion but many? please explain im new to this stuff :)

[@KaiCyreus]

nice lil Shellder

[@bramvanduijn8086]

Reading the comments it seems you should have explained the difference between ions and salts a bit more.

[@bramvanduijn8086]

You might enjoy learning a bit more about chemistry and the essential differences between ions and salts. An easy one is that you can't run a current through salts but you can run a current through water that contains ions. You also can't run a current through pure water. To be more precise, salt and pure water have a much higher resistance, if you pump in enough power you will eventually overcome that resistance, though in the case of salt it will melt and in the case of water it will electrolyse into hydrogen gas and oxygen gas, which might explode, depending on your experimental setup.

[@pitsahat2]

So if the pols and the equator become more extreme due to the lack of circulation wouldn't this extreme of temperatures create/force new ciculation?

[@MinuteEarth]

It could and has happened in Earth’s history. Unfortunately the periods of cold and ice tend to last for hundreds or thousands of years whereas the warming that causes it can happen in decades.

[@McJethroPovTee]

There's untapped sources of salt in various gaming communitirs.

[@miwhcyvybaksjd]

I listen to the episodes carefully, trying trying trying to guess the pun before you say it.

[@Yusuf-ke5iu]

It seems like everyone quickly changes their thumbnails/titles when their video just released. Wasn’t this called something else with a different title?

[@MinuteEarth]

Yes, we A/B test different title/thumbnail combinations to see which performs best. Unless the video does well right off the bat, in which case we just leave it.

[@thevioletskull8158]

So salt water doesn't exist unless you you add salt to it? And Sea salt isn't fully sea salt?

[@magister343]

So you're saying we should use the term "Electrolytic Water" instead of "Salt Water?"

[@MinuteEarth]

I propose we call the ocean “the Gatorade bowl.”

[@thegoodwitchluzura]

@MinuteEarth 😂

[@jaypaans3471]

If salt is dissolved, is it still salt? Hm, that's a phylosofical question...

[@bighotchip4231]

So how did ocean circulation work during times when polar ice caps were absent on Earth. Correct me if I’m wrong, but I remember reading that Earth did not have polar ice caps for like 300 million years and the oceans were stagnant lifeless puddles.

[@RemiGozard]

Please think on reducing or refusing animal products, one on the main factors of climate change.

[@bimlauyomashitobi421]

So your argument is “There actually isn’t any milk in chocolate milk because after you add the chocolate it combines to make chocolate milk, not just milk and chocolate! Look at me, me smart!” You are just getting desperate for ideas aren’t ya?

[@jobansand]

I think it's a clickbaity thumbnail, to draw in people. The education- the main point of the video and channel- is still good. It's not an argument.

[@bramvanduijn8086]

No, milk remains chemically milk, it just gets some chocolate chemicals mixed in. It is still milk and chocolate, just mixed together. Salt on the other hand undergoes a chemical reaction that leaves it in a completely different state, kind of like how ash is not wood anymore, or how electrolysing water turns it into hydrogen gas and oxygen gas. It is not water anymore, because water doesn't go boom. It is a different collection of chemical compounds. Scientific proof you can check yourself: You can measure the amount of ions in water by running an electrical current through the water, but that same current won't run through salt. Because salt and dissolved ions are not the same thing.

[@WanderTheNomad]

@@bramvanduijn8086 wow, you actually put that really well

[@kennyholmes5196]

@@bramvanduijn8086 So, it's basically the difference between ice and water, then. Because while electricity can't run through solid dihydrogen monoxide or monosodium monochloride, it _can_ run through both of them when they're liquid. And even then, it still requires a little help; pure H2O is actually an insulator!

[@garyermann]

There's something kind of terrifying about the fact that so many MinuteEarth videos can be summarized as "Here's a cool thing that the earth does to sustain life.... and here's how climate change is going to screw all that up."

[@tiaxanderson9725]

To be fair, not MinuteEarth's fault...

[@wigiboo2228]

Ok genuinely curious but if ice caps are needed for ocean currents and sea life to exist, then how did that stuff happen during the cretaceous period? Cause there were DEFINITELY no ice caps back then, but there was definitely an abundance of life on land and in the oceans

[@joeyjoe7930]

“And keep an eye on its ions!” Hahaha nice!

[@AelwynMr]

Well, if you put it this way, you could just as well argue that there is no such thing as salt. Salts are just a bunch of ions put together in an orderly fashion, salwater is just the same thing spread out wothout order and in a larger volume.

[@venkatkrisshna]

Yes exactly. This video does a poor job of explaining salts.
