You’d never tell just by staring out from a sandy beach, but the coasts are gradually getting darker, and the effects of this darkening are only beginning to be understood.

Has it never occured to you or your sponsors that such small numbers are annoying, even insulting, to the viewership? Limited offers are already bad, reading as, "Hey everyone who saw this video a day late! We're gonna waste your time talking about a promotion you have no possible chance to benefit at all from! But hey, it's a great product! That's why they let people try it for free! Other people, not you, pleb." But 100? On a UA-cam channel that has already reached 54 times that number in less than a half hour? No. That's beyond insulting. You want my money? Try not pissing me off with offers that qualify as a statistical error in viewership.

@@InfinityOrNone ? get a real issue to get pissed off about.
Is it because People are pouring 'Vantablack' paint into the Oceans? (Joke)
@@johnsmith9903? Find someone who cares what you think.
Wow this is eye opening. Especially the part about how Kelp plays a role in carbon capture. The ocean equivalent of deforestation.
How is it eye opening. THE MEDIA IS A CENSOR
It's eye opening for me because I didn't know this was even an issue with the ocean?
@@McLebo
The conspiracy theorist rears its ugly head…….
Please don't be discouraged by the other's comments.
But to queue up to: Please learn more about the ongoing climate crisis, there are so many things out there that are laughed at when presented as part of the solution, because people just dont know things. Like.... all kinds of things, comparisons or relations :D
If this was eye-opening then you should watch Seaspiracy. Toxic Puzzle is another good documentary worth watching.
the past few years my mental health has declined dramatically to the point where i got paranoia and psychosis symptoms due to lack of sleep, somewhere along my recovery i started watching scishow before bed and i’ve been doing it everyday for almost 2 years. the sound at the start is so soothing and it helps me not get debilitating nightmares. unrelated to the video but i just wanted to say thank you scishow team, in a way you guys have helped me become functional again ❤️❤️
"coastal darkening can cause kelp to sequester up to nearly 5 times less carbon" In literal English, this means: coastal darkening can cause kelp to sequester down to nearly one-fifth as much carbon (as compared to their sequestering under clear coastal water).
If someone wants to speak in terms of "less", then it is 80% less.
Fully agreed. "Five times more" makes sense, but "five times less" doesn't. I have much trouble with this recurring mistake while reviewing and correcting pharmaceutical documentation.
There isn't a problem with this. It's division: 5x less is x/5. Idk, we used to get tested on our ability to read annoying, applied mathematics problems in English when I was a kid.
87% of carbon is from non man made causes
@@jar407 what does this have to do with OP's point? Less carbon will be absorbed by kelp either way.
@@jar407 I think you mean carbon in the atmosphere and oceans. Carbon atoms were made in stars. We are made of stardust (so to speak). If there were no carbon, there would be no us. If there were no carbon in the air, there would be no plants and no plants to give us food and oxygen, so again no us.
The darkening sounds like a disease that turns you into a evil villain.
Hmmm. And well it may be.

Half my life is over. I feel sorry for our kids and grandkids who will have to deal with this mess.
Hi, I work as a housekeeper and I’ve noticed that even after I’ve cleaned a mirror well, lint from my rag or dust in the air will “settle” back on the vertical mirror! How does it stay there?!?
Probably due to static electric electricity or something similar causing an attraction between the lint/dust and the glass surface of the mirror/window.
I'm just curious about why we aren't addressing this problem of intense fertilizer run offs? When we are now seeing and knowing it effects a lot!
Because K+S and BASF would suffer. And those billionaire CEOs need their private jets and 110 foot yachts. And pay ZERO taxes!
Because animal agriculture would like you to pretend it doesn't exist so you'll keep paying for their products.
@@suicune2001 Word Police... Alright, pull over... You mean Animal Husbandry; tho the animals need not, be, or have changed from, or identify w any particular gender...
@@terryenglish7132 LOL! I stand corrected.
Could you do a video on algae blooms and the things that cause them?
Phosphorus and nitrogen, from industrial and Fertilizer run off. Nowwwww why does that make algae bloom, because plants need nitrogen and Phosphorus to grow. Too much of it too much plant and now we have an over abundance of dinoflagellates blooms. Beautiful but deadly.
I can go into more detail if you'd like if that doesn't make since. But I tried to make it simple.
Do other chemicals or farming pesticides/growth chemicals cause other types of toxic blooms? And can you kill the algae without harming other marine life?
@@Youngblood124_ and noooo I wouldn't suggest trying to kill or put anything in the water to harm the dinoflagellates it would cause damage to everything in the ecosystem. Which eventually leads back to you.... since you consume water, and eat fish ect.... or we'll leads back to humans in some way and or form.
Meatlesspi3 was perfectly right :D
Just wanted to add an example of why killing certain things does not really work.
Phosporous and nitrogen are normal fertilizer also used in gardens. If you drop too much fertilizer on your lawn, it will damage a lot of plants roots, only the more sturdy ones will get a benefit from being "overfed". Usually we call them "weeds". Now, if you wanna get rid of the super-charged weeds, you will damage anything around too. Be it with round-up, torches or just digging out the roots (and cutting other roots doing so).
Now comes the thingy that algae have going for them: They are ancient MFers that have seen way "worse" chemical balance on the planet and they can take it. So while fish will just drop dead because stuff is toxic, that's actually how everything back then was and all those algae prepared most of the oxygen we needed later.
"The Darkening" sounds terrifying
Amazing pack of information in such a short time! Also, first time I hear about this phenomena... Sad one 😞
I have heard about this about ponds, while I took environmental studies class about a decade ago.
Watch Seaspiracy if you haven't heard how the ocean is screwed.
Scishow has helped me with botany a little bit. Now if I could just get a video about tree anatomy, phylum, cambium, vascular rays? Please!
If something happens 'five times less', does that mean it happens 20% as much as before?
Yes. I don't like that this way of saying it is becoming more common. Saying "one-fifth as much" is clearer to me because it means exactly what the words say. If someone wants to speak in terms of "less", then it is 80% less.

The oceans have sustained life on Earth for 500 million plus years, some 90+% of life in the oceans is in the coastal zones. (i.e. on the continental shelves)
A thing not mentioned is the change in albedo, which has a major effect on ocean temperatures, especially in shallower water.
So, seems like there a ton of feedback loops that accelerate global warming, like loss of albedo from ice, melting permafrost, darkening oceans, etc - are there any identified negative feedback loops for increasing temps? (cloud cover albedo from increased evaporation, although that is probably only visual spectrum)
If particles in the water block light from the water column, then that would mean more is reflected, increasing the albedo of coastal regions? It wouldn't be as high as ice, but it'd certainly be higher than the low albedo or normal ocean. It's probably not that straight forward, I'm not sure of differences in heat and light reflection, as I imagine different surfaces reflect different wavelengths better than others. But it's interesting to consider.
@@Laurastar2009
The particles could be absorbing light rather than reflecting it. In which case, the effect would be to further reduce albedo. I'd expect that, depending on particle type and light wavelength, both effects would be occurring.
Coming back to revisit - if the oceanic currents collapse, which bring warm water to the poles and cold water away, we could see a resurgence of polar ice (as the cold water isn't carried away) and total albedo increase at least temporarily. Regions like Western Europe could actually get colder if it plays out this way.
Only major effect I could find
Remember the ice age that happens bcz smoke in the atmosphere? It's basically that, but localized to coastal waters.
We don't know how bad the effects are, but we're pretty sure that it's worse than what we already know.
Over time we have indeed affected the world in "not so good ways." And now the natural world, the living organism that it is, is slowly attempting to cleans itself from our affect on it.
They always get me with the titles. I'm like hmm, didn't even know the ocean was getting darker. Let's find out why lol
people like you bring these massive events to the light but unfortunately humans don't care and disaster will continue to expand
I feel like the implications are still a bit mercurial and we don't know the consequences yet but I think this could really decrease phytoplankton diversity because only phytoplankton with vesicles that help them float can survive high turbidities and this is why cyanobacteria dominate eutrophied water
Yeah, what he said!
I’ll go ahead and tell you what the consequences are, since you’re unaware. The extinction of the human race.
We’re well past the tipping point on this. Saw it coming 50+ years ago.
mr obvious over here. Well duh 🙄🙄
@@dr.jamesolack8504 what's weird is, we came together worldwide and addressed the cause of the hole in the ozone layer remarkably well all things considered. It worked and the hole shrank. But when the issues are related to fossil fuels nobody gives AF. The issue is politicized to the point they then fell for their own propaganda.
Fertilizers, plastics, carbon, methane from uncapped wells, pollution from drilling, extracting carbon out of the air and then polymerizing it back into plastic, all ignored. Our big feat is shoving a paper straw into a plastic lid on a plastic cup, or lithium-ion batteries extracted from 3rd worlds using child labor. Which only powers e-waste that gets burned in 3rd world countries in 2 to 5 yrs due to planned obsolence and consumerism. I feel dirty as a human now.
@@dr.jamesolack8504 nice. That means we can dump oil into the waters, spray any chemical we want anywhere we feel for any reason, hunters should be able to kill as many animals as they want, vehicles can be left running 24 hours a day and so on since it's already solved that we are going to die out as a species.
That may not be the best attitude to take, especially with things that are so complex I don't believe anyone really knows what's going to happen in the future. We may understand segments of things but the entire overall picture of the climate in perfect clarity and so thoroughly that we can product what it'll do in the future when we can't answer why things happened in the past because of missing evidence. Then we want to look at tiny episodes in the past that are not perfectly understood and apply them to things happening now to predict the future.
I know I'll get all sorts of flack about being a denier but that's not what I'm saying, I'm saying the information isn't solid enough to say 100 percent one way or the other but we are leaning towards one over the other currently.
Insane that they were looking into this in the 1800’s
Going to call BS on the cumulative and does not disappear over time. All things non soluble will precipitate out of the column at some time.
Particulate in the water is accumulating faster than it can precipitate out.
"Particulate in the water is accumulating faster than it can precipitate out." Then it is accumulating. What is your problem?
This is one of the scariest videos I have ever watched. There are all kinds of climate change disasters in progress such as forest loss causing increased C02, microplastics in the food chain that ends up in us and various horrible chemicals that are changing ecosystems and generally wiping many of them out, but the idea that water is getting darker and phytoplankton is in danger of near-extinction is so terrifying that I can't even put it into words. Without those tiny animals all life in the ocean will die and we on our "safe" shores won't be far behind.
I think it's good that we talk about things like this so more research can be done. By the time we have figured out if it's bad or not it'll be too late anyway. All we do is talk and talk but rarely do people actually do something because it cost time, money and effort. Even if this is proven to be really bad for the future, what exactly is going to be done? More talking. Yep. Just let the future generations deal with the problems right.
Nothing can be done short of getting fusion up and running
Or going back to the stone age
"Green" energy and its advocates always try to hide the mining side of their energy model
@@azmanabdula As if no mining would be required to build/fuel fusion reactors.
A whole hell of a lot can and should have been done starting decades ago that could have easily softened, delayed or even completely averted the climate disaster we are rapidly entering.
If it weren't for all the subsidies that fossil fuels have received, artificially inflating their profitability, we'd already be much closer to on the right track but instead we've gone out of our way to make things even worse.
Maybe instead of touting misinformation you could try actually helping rather than praying for your fusion miracle. Fission works great now and is safer for everyone than burning carbon but the misinformed masses are scawwed of it.
To be fair, each source of energy has its advantages and disadvantages, green energy is no exception
A large part of the problem is the organizations funding the "Let's wait until we have more data" push really want nothing to happen because that might actually cause them to make 5% less profit.
If you want to actually do something instead of just talk, then go vegan.
Literally the smallest things, the things on the bottom of the food chain are by far the most important factor of the entire biological ecosystem. The same goes for economy's in society but sadly we have yet to see that and implement that to take better care of lifting up the poor low income people, it would influx benefit every other aspect of the economy. Just like plankton, krill, zooplankton, phytoplankton, kelp, etc.
A darkening water column also means a higher albedo on the surface, as those particles reflect more sunlight. Seas and oceans typically have very low albedo, I'm curious of the implications of higher albedo around coastlines. Is the difference enough to influence water temperatures in coastal environments?
The Earth's complex interconnected systems have always fascinated me, and water clarity was not something I'd ever given any thought to before, so thank you for highlighting the topic (pardon the pun).
I'm sorry but can you explain to me in easier way what albedo means? I googled it and I can't understand its complicated meaning. I can only understand basic English. 😅
good point, considering how much carbon dioxide the ocean also absorbs. We are currently not seeing the expected effects of carbon dioxide emissions because of how much the ocean absorbs (aside from how it may be affecting shell growth), but increased temperatures from increased absorption may change that
@@HennessyGracias The albedo effect is how much energy from the sun is reflected by a surface. I'll simplify it by just saying light. Ice has a very high albedo because it reflects a lot of light (snow and ice look bright to us) but water has a low albedo which means it doesn't reflect much light (so the seas and oceans often look dark to us). Rock, sand, plants, and even cities all have different levels of albedo, so what is on the surface of the Earth is very important for how much light/heat from the sun is reflected back into space. I'd reccommend searching for "albedo effect diagram" and looking at the pictures. Hope this helped.
@@calladricosplays I'm wondering if the particles are reflecting more energy though? And so possibly meaning those coastlines are kept cooler than without the particles. Could increased runoff etc. be counteracting some of the rising sea temperatures?
@@Laurastar2009 anything in enough quantity that limits the photosynthetic properties of Marine plants, alga, and Cyanobacteria is probably going to be greatly affected. That’s a good question.
Love the use of gamut.
Ah, there it us, the daily reminder that the world i live in is a bleak hellscape.
Think of what those sea animals must be thinking of us!
@@chinookvalley Most sea animals don't even know what a Human is. They're home is just becoming less hospitable every day and they don't even know why.
I am comforted in the fact that the Earth never pollutes itself. No volcanic eruptions ever. No continent shifting causing earthquakes. No solar radiation. The Earth has done more to pollute itself over history then humanity ever has.
Who are you arguing against? I have never heard anyone make those claims.
Salt water kills most trees but root still hold soil together for a bit before completely deteriorating, releasing soil and their eco systems into the water.
Just add this news to the ever-growing list of bad circumstances we all have to look forward to in the future, unless we work together to slow or reverse these processes.
Well, only one thing for it, we must put lightbulbs underwater... :P
“Coastal Darkening” sounds like a term that came from a marketing agency or politician as a mitigating term for pollution.
'Gainfully employed' has been used before to describe slave labor in private prisons, that charge prisoners for their imprisonment, and if they don't pay their sentence is extended.
Might have been better to end with the note "but we know that climate change exists and not burning fossil fuel is the key"
Might have been better to end with the note "but out-of-control population growth, especially in the third world, is killing the Earth."
@@scottslotterbeck3796
Yeah, Scott. Let’s blame it on the 3rd world. The U.S. and Europe play such a tiny role in climate change……

Good evening everyone
It never ends just another bad news day again
Just curious, isn't their potential user discrimination using the secchi disk? Like if your eyes are better than mine the disappearing distance can be further?
I suppose it would depend on the number of readings and the amount of variation in vision. Since the data already requires a large sample size to account for hourly/daily variation, presumeably visual variation might be low enough to be drowned out by a large sample size too. But I wonder if there could be a statistical function applied that accounts for variation in human vision. One would presume anyone taking the measurement (certainly in modern times) would have vision within a predictable range, aided or not.
Certainly! I have tested it with my colleagues, sometimes due to different eye characteristic, the depth reading can be different.
Yet, secchi disk itself isnt quite of an instrument that detailed until cm or maybe mm. Most ocean secchi disk has precision unit of meters, and landwater secchi disk probably has precision unit like per 50 cm. But it is still accurate enough, and easy to use so it is still common for novice hydrographic surveys
Just saw a ducumentary about the boring billion.... darkememig waters and climate change towards heating really makes me anxious rn.

Hello, darkening, my old trend... 🎶
I’ve come to talk with you again…
Carbon carbon carbon....not one single mention that the other end of photosynthesis is oxygen production which is more important. If there is a die-off of these photosynthetic organisms, oxygen production will follow. Since the majority of oxygen production is done in the ocean and we are deforesting areas that contribute to this production, we are slowly tying a plastic bag over our heads. As a famous author once wrote: So long, and thanks for all the fish.
Well this sounds pretty dire.
Luego también el sol será más si es oscura el agua lo cual aumenta el cambio climático.
If the costal waters warm up , there is more algae in the water and as algae dies it turns black in a pool or a fish tank so what's the big mystery here ?
But if algae blooms from agricultural runoff are the principal cause of coastal darkening, then the absolute amount of photosynthesis should remain steady. It just means that more of it takes place at higher ocean strata.
So there is more algae, and yet the ocean isn’t taking in more Co2? Do people forget that algae also photosynthesizes?
There's also toxic algae that literally kill you and all the fish that swim in it. Not all algae is good algae.
This is quite different topic. CO2 being absorbed into the ocean more is due to the imbalance of CO2 concentration in the atmosphere.
However, about algae, yes they photosynthesize at day. At night some of the algae got decomposed by bacteria, which decomposition itself produces CO2 and consume O2
We are so effed
ikr
The world is totally capable of mass extinction events, so us helping that along can't be so great..
Damnit
We need to stop it before it's too late. The answers right there. I'm not sure why action has not been taken by officials?
The Chemical Industry can fix this problem easily by introducing vast amounts of their product into the sea!!
I would love to see a video on immortal animals. And whether they continue to evolve as they age, because their cells divide and mutate. I think it would be possible for a new gene/trait to take over through cell division and mutation, leading to evolution in the animal as it ages over centuries.
since we havent been taking records for too long hard to see much into this, def not before large human environmental impact. I would think all the dams created would dramatically lower the the amount of sediment flowing from rivers as well as with the amount of rain and with the dams messing with the temperature and amount of the water released. Also with all the ships that travel world wide and emptying filled ballast of water introducing many different non-local species would mess with the local ecosystem.
Sediment flow (erosion) is also effected by soil instability, which is reduced by a lack of vegetation's root systems keeping everything neatly in place. When people rip out plants and trees alongside waterways (usually without permits, le sigh) or cause them not to be placed and grown there at all, especially in softer, moist-er or sandy soils, it's like trying to hold sand in your open hand; it just falls all over the place and makes a mess instead of staying put.
Hell yeah
could be that phytoplankton which are bioluminescent are getting dumpstered.
Just put some lights underwater, bam solved your problem, wheres my nobel peace prize
Everything is so depressing
Isn't it pathetic that humans do this stuff without planning or testing, then see evidence it might be a problem, then have to fight to agree it's a problem, then have to fight to agree to do something about it. And we rarely get to the last step.
Wow
I'm still not sure exactly why coastal darkening is happening. Is there supposed to be a comma after 'why' in the title?
All oceanic plants are gonna end up evolving into lotuses now

Amazing, priest/scientists. He's leaving no stone unturned.
Why the coasts are getting darker.
Is there any way that we can collect that algae to help combat climate change?
ua-cam.com/video/3ZKbyXCrTG8/v-deo.html I hope this helps. I love this channel, too.
Reduce the population growth rate to a stable population.
@@chinookvalley That is one of my many sources of knowledge in the subject. I think that the video is actually about algea being somewhere that harms the planet, instead of helping it. My question probably would be better phrased, "How difficult would it be to collect the algae and move it somewhere that it can be more beneficial? "
We honestly can't catch a break can we? Sheesh.
This is a real problem the world and us gonna die 2012 :(.
How do we know our Secchi measurements match the ones in the 1800s? Maybe our white paint is more reflective or the black paint is less reflective or maybe the amount of light entering is different due to atmospheric changes.
Good point, tho hopefully someone used an antique one vs new to see any difference. But certainly atmospheric clarity would cause eronious readings as would changes in solar radiation.
Oh Boy! More bad news, us humans could F up a steel ball.
The reason is simple. There's oil in it.
Oil floats. Duhhh…
"the onset of climate change" as if the climate wasn't changing before us?
It was overall pretty steady until the industrial revolution where we began pumping greenhouse gasses into the atmosphere and it got hotter than it's ever been for millennia.
There is no human being with a functional brain that does not believe in climate change.
If insults are you best tool... not sure how to help you. Can't remember saying climate change doesn't exist 🤔. What I am stating is.... when you look at the big picture... (a millenia is nothing) it existed long before we ever did.
@@dr0nwind It’s only an insult if you deserve it, if you want to be a smartass, then anthropological climate change is the correct term, and an undeniable fact of the world.
