Rick: Coral! coral? CORAL!? coral? COOOOOOOOORAAAAAAAAAAAAAAAAAL!!!!!!!!!!!!!!!!!!!!!!!!!!!?
+Naj Kraemer Coal?
+Naj Kraemer :v
+Naj Kraemer Funnily enough, my friends and I were talking about how one of our friends thought that Carl's name was Coral. We laughed about it, but little did we know that Joe was spying on us to release this video...
+Naj Kraemer
nope, i guess it was Corel Draw.
CAAARRRRRRRRRRRRRRLLLL THERES A DEAD HUMAN IN OUR HOUSE
COnservative leaders: "Its bullshit"
I see what you did there "CO"
+Fabian Honor good one
Fabian Honor
conservatives are they liberals or republican
liberals are morons without republicans slavery would of never ended all anti-slavery presidents were republicans (up until slavery and enormous racism ended all liberals were racists) but it's over now.
OH MY GOD! thank you whoever put that Coral from TWD in, wish i could do more then like and favorite this video
I was getting super sad about this, and you put that twd bit and I lost it. You're great!
Lovely video, I'll definitely be showing this to my students. Thanks.
+A Level Physics Online I hope your my teacher because my teacher shows movies sometimes but not always :C
Roko Čeko What language are you speaking? Norlandic english uses your, we don't use you're, we only use your. Search it up buddy ;)
+Trollerman Sixtysevan amazing comeback
I use Dropbox. May this channel stay forever open.
now I can't unhear Rick calling Carl "coral"
This is a wonderful video, but there is more to the story. It's not just that the oceans are getting warmer (causing coral bleaching) but they are getting more acidic and this decreases the ability of corals and shell building organisms to build their homes. The pH of seawater is a crucial factor because these organisms need calcium carbonate, CaCO3, in order to survive. Elizabeth Kolbert explains it like so: "Adding carbonic acid to the water complicates their efforts, because it reduces the number of carbonate ions in circulation. Practically, it means shrinking the supply of material available for shell formation.(Imagine trying to build a house when someone keeps stealing your bricks.) Once the carbonate concentration gets pushed low enough, even existing shells begin to dissolve." So what we really need to do is not to produce new types of corals, but to stop emitting extreme amounts of CO2. That is what I thinks anyways...
+birdsmeet Acidification is definitely covered in the video! Everyone should read Elizabeth Kolbert's work on this stuff, though.
+birdsmeet Another thing is all the oxygen that algies and the coral reefes are making will dissapate, lowering the amount of oxygen and in turn ozone. Due to the fact that our best UV-protection is now gone we will get hit by alot of radiation, and in turn lead to the earth beeing mutants!! (supermutants in Fallout here i come)
+It's Okay To Be Smart Yes and thank you for mentioning it, I just wanted to bring an additional explanation to the problem. Also, I have discovered Elizabeth Kolbert after your video on mass extinction last year and I am truly thankful to your channel for that :)
I admit that the part about trying to build a house when someone keeps stealing your bricks was funny.
+Jim Eriksson aaaaaaa another person mentioned Fallout
why does it have to be sixty dollars ;n;
youtube's doodle changed so i typed #Ourstolose to find out whats it all about then I saw your video and since you are one of my favorite youtubers I clicked on it and I just realized how early I am
HOW HAVEN'T I FOUND THIS CHANEL UNTIL NOW ??? awesome video man ;)
OMG the inserts of 'Carl' from The Walking Dead made me burst out laughing! Awesome touch of humor!! :D
And great video overall too!
Please reply joe, then i would show this to my science teacher
+Shane Thetremour Hello Shane! And hello Shane's science teacher!
+It's Okay To Be Smart YES!!! thank you joe!
+Shane Thetremour If you can watch Netflix I would recommend, Mission Blue, Sylvia Earle's Campaign to save the Worlds Oceans! Fantastic :)
+Shane Thetremour
Apparently *It's Okay to be Misinformed.*
Much of what is known about reef response to temperature and pH comes from laboratory experiments. That is, from changing the conditions in an aquarium to see how the ecosystem responds. Many in the ocean acidification research community recognize that this is really just a stress test that does not simulate real-world ecosystem adaptation.
Reefs in the real world are not restricted to a fixed ecosystem. As one species declines, another that is better adapted can move in. Reefs around the world exist at many different temperatures and pH levels, each having an ecosystem adapted to those conditions. For example a recent study of Palau found that despite having a natural pH far lower than any anticipated acidification, it has a very diverse and thriving reef ecosystem - it's a haven for recreational divers. advances.sciencemag.org/content/1/5/e1500328
The denizens of the reefs have been around for millions of years and survived a wide range of temperature and pH. In all likelihood, reefs won't disappear as organisms die off, they will just gradually change as different organisms migrate in while existing ones radiate out to areas better suited to them. If temperatures do start increasing again, we may see coral reefs expand their range into higher latitudes. We'll see more reefs not fewer.
In the popular media bleaching is treated as evidence of coral death. Coral is just a rock created by coral polyps on its surface. Bleaching is in reality a vacancy of the coral which will eventually be repopulated with coral polyps and continue growing again. Periodic coral bleaching is natural.
George Applegate Oh you know what! go and get a life else where, this is so annoying. The trolls on here are so sure of "It's my word, not their's"" If that's the case get your own channel! Prove to us that it's all bullshit and let us people make our own mind's up. Getting pretty sick of people trying to tell me what to think!! Misinformed is your opinion ok, we come here for our own reason's. now wither you agree or not, it is not your place to dictate... Freedom of speech, but only if it make's sense to the viewer! You know exactly what I am saying, so take it else where and let us get on with what we believe!!
this deserves more awareness..
Syliva Earle has a documentary called *"Mission Blue"*
It's on Netflix :)
James Cameron is also in the documentary
i signed up for the petition because of you +It's Okay To Be Smart. if you think its something to pay attention to, im on it
It would be awesome if Bill Nye made a guest appearance on this channel. Together they could change the world!
+CmonMan I agree. This would be awesome. Bill! Call me, dude!
+It's Okay To Be Smart Bill Nye would be a perfect fit for this channel. Especially your in detail scientific explaination of climate change through increase in human C02 Emission reminded me. Would it help if all humans would hold their breath more often?
+CmonMan No. people are still to stupid to want to learn.
- FAWX -
Carbon Dioxide percentage in atmosphere approx 0,038 %
Human CO2 Emissions are estimated to be 1,2% out of overall Earth CO2 emissions
So Human CO2 effect on atmosphere amounts to 0,00046% or 1 particle out of 217.391.
99% of warmth on earth comes from the sun.
Do you even climate change bro?
Have this guy on. Here’s what’s happening with the Great Barrier Reefs now ua-cam.com/video/ze9Dybm-rLk/v-deo.html
I watched a video (wish I could remember what it's called) of people who made Reefs, put them on the bottom of the ocean, and then showed what they looked like a short time later. What a great idea it is! Fish, etc were back living in the areas again :)
I love this Channel. Just found out. Amazing
Oh my gosh the Carl joke, nice job XD
LMAO! I didn't know that "Coral" was I thing. I thought it was just me!
Hi! Great Video!
One thing your video made me curious about is why the coral is "kicking out" their algae friends.
You did a stellar job explaining their symbiotic relationship, but didn't really draw the connection between the ocean's rapidly changing climactic conditions and coral bleaching.
If you (or any fellow UA-camrs) could explain, it would be much appreciated!
The United Nations Climate Change Conference in Paris might be our last shot to reduce carbon emission and slow down climate change. So far only Germany and a few smaller countries seemed willing to do it. USA talks a lot about it, but does little.
Interesting video.
The "The Walking Dead" part cracked me up! Very interesting as always.
Amazing episode! Informative, very funny (the TWD collage was super funny!) but also very shocking. Climate change is such a big issue.
Oh my god, the Walking Dead reference, ha! Definitely showing this to my students, love your channel!
I was watching this video while on my school bus and I started laughing like a maniac when they showed the walking dead, needless to say now they all think i'm crazy😂🙌🏼
Oh the coral jokes... The six million coral was brilliant XD
Wasn't able to hear "coral" without thinking "Carl" after that part
I just saw the new logo on yt and types on google #ourstolose
+Emir Kugic same ;P
+Emir Kugic #ourAgenda4NWO
+Jason Hives Idiot.
Richard Rothschild noob
that is such a cool use of genetic modification, likes seriously awesome
Coral is so beautifully symbiotic. It can even be used to graft with human bone, and it doesn't stunt the patient's growth nor create protuberances. It's absolutely wonderful. And unlike bone marrow from donors, there's no chance of the body rejecting it as there is no conflict of blood type.
Because coral does not rely on blood. The only thing I have to question is will the coral be able to help produce blood as the rest of the skeletal system does, be effective at doing so, or be passively inert to this process altogether?
I still don't understand why some scientists believe that global warming is not a concern. Is it because they feel that they're not anywhere near the time to panic?
+Isoluniv_714 Z For life is not a concern, life will prevail but but humans i don't think so.
+Purple Chaos Its a concern because its changing too fast.
+Isoluniv_714 Z It's amazing what you can believe in, with the right amount of money from lobbyists.
+Purple Chaos correct, however we are accelerating the proccess much faster than it's supposed to be happening, this leaves a lot of species in the dust not having enought time to evolve to the new climates and weather
+Isoluniv_714 Z most scientist do think it's a concern there was even an article on npr that mentioned how a lot of climate change scientist are actually getting really depressed at their jopbs because they are viewing the beginning of the next mass extinction
see 4:12 for the real reason for reefs dying and for AGW. Until you get out of denial, we have no chances for a solution to either.
What a coincidence!? I just wrote an 8 page research paper about the effects of humans on coral reefs. I hope I get a good grade! There are corals in the Persian Gulf that can withstand the rising temperatures, but will run out of room to grow. This is due to corals not having enough aragonite sea bedding from the effects of ocean acidification.
Btw I'm not insulting you I'm insulting people who still deny global warming and the effects
research from the university of quensland suggests that Porites cylindrical, a species of coral found in the Heron island lagoon and on the great barrier reef can protect itself from ocean acidification by a producing a neutralizing fluid. Also, some research suggests that the origin of life could not have been in water as once thought as it prevents RNA from forming, this is backed by lab research which has found that a much more ideal starting solvent for life would be formamide.
Great Vid!!!
So true! Thank you for teaching the world!
Genetically engineering coral sounds like an awesome solution. Would you ever do a video about geoengineering?
This one made me tear up.
OMG That walking dead part was hilarious :-)
My environmental Science class thinks that you are great!!
Great video on a horrifying topic, thumbs up!
Thank you UA-cam for making me aware of the hashtag! #OursToLose
Only briefly mentioned ocean acidification, caco3, carbonic acid and zooxanthallae
I made an essay about how coral reefs are in danger, the rainforest of the sea.
That's not pollution from smoke stacks. They're cloud factories.
That sounds like something Calvin would hear from his dad.
"Dad, what are clouds made of?"
"Well, buddy, there are certain factories that produce clouds and put them in the sky. It's a very big business. Makes a lot of money."
"Who pays for the clouds?"
"Everyone does. The cloud factories are funded by the government. In turn, homeowners have to pay a cloud bill every month. If you don't pay the cloud bill, then the government comes and puts a big umbrella over your house so you don't get to look at the clouds anymore."
they make clouds of death.
+jrjubach
Depending on the industry, that might be true. Usually the clouds you see is really simply condensing water vapor (= clouds)
Fenton Bevan
Honey, an increase in Albedo does not increase, but decrease earth warming, due to the increased reflection of sun light.
+Frank Schneider But when they cover the white snow in the poles, they do increase Earth's warming.
Coral reefs have been called the rain forests of the oceans. I guess if we weren't so fixated on land-based life, rain forests would be called the coral reefs of the continents.
We need to put this in the language that the average Americans can understand. Translation: *Climate change is destroying Nemo's home! We gotta reverse climate change or Finding Dory won't be released in theaters ever!*
One of my classmates did a speech how cows and meat industry is the reason behind climate change. I was suprised because I haven't any science youtuber ever mention this. So is it actually true?
haven't heard*
+Simo Puttonen Cows fart out a lot of methane, which is a very potent greenhouse gas, so there is some truth to it. I have heard that the quantity of gas is comparable to some other major contributing sectors. However something to keep in mind is that the gas is coming from the fact that they ate plants which had to absorb atmospheric carbon to grow, so to a certain extent it's offsetting. This kind of gets lumped in with the response to the common climate denier point that our carbon emissions is only a small fraction of emissions due to plant decomposition, cellular respiration, etc on earth. The difference is in one case it's part of a cycle, in the case of fossil fuels you're releasing carbon which had been sequestered in the Earth.
Now technically the plants probably absorb mostly CO2 which then gets ultimately converted to methane so it may not be totally neutral. I'd be curious to see what the math is on that.
I'm quite sure there's some youtube videos on this. I think minute physics did one.
+Simo Puttonen There's no single reason behind climate change, but industrial agriculture is definitely a big contributor, all the way from the farming of grain to feed the animals to the "methane emissions" that come out of the back of cows. There's no easy answers to this stuff, but it shouldn't be ignored.
+It's Okay To Be Smart Sorry to be that smart ass to mention that most of the methane actually comes out of the FRONT of the cow through burps rather than farts!
According to researchers at New Zealand’s largest Crown Research Institute, AGResearch, up to 95 percent of the emissions comes from the cow’s mouth rather than its behind. It’s estimated, through whichever orifice, that each individual cow lets out between thirty and fifty gallons of methane per day. With an estimated 1.3 to 1.5 billion cattle in the world today, this adds up fast.
Another great video, guys. Could you please explain Fermi's Paradox?
Thanks...
The walking dead scenes had me😂😂
YES WE CARL!
3:40.
"Half of all tropical reefs have dissappeared over past 30 years"
Can anyone back this up or is it just bullshit? I cant find any info
coral, coral, coral, coral, coral, coral.....
SHAUN!
The problem is we won't do a thing about it, because we will have to change our ways, and we won't do that. We will consume our way into oblivion!
I love the Walking Dead connection. Even if this talk about losing coral reefs is extemely serious, because dammit it is.
I read an article a while ago where a marine biologist explained the hype around losing the coral is really just hype in their research they found that at certain points in time large amounts of coral die off but it always comes back. coral has existed long before the dinosaurs it has an incredible ability to adapt to new conditions and it's long history on earth through Ice ages and warming period and even a asteroid impact is testament to it's strength.
+jump oricakle Was it in the Onion?
Ahuc899 nope I just can't remember where it was but I know about onion news and it certainly wasn't there
+jump oricakle alex jones article?
Half the rainforest is gone in 50 years, half the coral reefs are gone in 30 years, there are more natural disasters, the earth is warmer, millions of species are suddenly dying out at the rate of a mass extinction in just a few hundred years...
Hmm what a coincidence that all these things happen right when humans are putting a mass load of carbon dioxide emissions into the atmosphere... What a coincidence...
SusannePlays there are not more natural disasters more storms get reported though now that we have radar/satellites to see them. extinction is a natural part of life new species are always evolving and old ones dying off. also the human population is greater than ever and you mentioned deforestation. habitat loss is far more likely the reason for species becoming endangered than rising CO2 levels.
That Walking Dead part really got to me, I was dying of laughter xD
If we can do something similar to coral, like what we did to corn, I think that would be amazing.
KNOWN, hydrothermal vents put out way more CO2 than humans. We are quite arrogant to think that we can have any lasting effect on a system so rubust and evolved through millennia of celestial bombardment and internal upheaval. The system will eventually evolve a mechanism to counteract any minuscule impact we think we have. With all our complex capabilities, to this day we can't determine if it is going to rain tomorrow or not. We have NO idea what we are talking about when it comes to a system of such scale and complexity as the earth an we should just stfu about it and fix something more pressing. Besides the sun is going to explode eventually and incinerate the earth anyway.
I agree with your point. The world had been in conditions far worse than what we have today.But as the world try to reestablish equilibrium, our species might not survive that change.
+The VSO Gun Channel The sun isnt going to explode, its going to expand and make life on earth impossible, but that is billions of years away. Weather and climate are two different things and climate change is happening.
+The VSO Gun Channel the problem is that the sea takes in the same amount of CO2 as the world puts in, so it's balanced, yet our contribution is not as easily balanced because the sea has already taken in a lot of CO2 and may not have space for much more. This allows CO2 levels to rise, causing the temperature to increase. We can have a lasting effect on this planet. Just look at how low fossil fuels are running.
Pokedel Asel The sea actually is absorbing a lot of our CO2, but its still a problem because its turning the oceans acidic.
Yeah right, instead of changing our destructive behaviours, the system, let's change the corals. And let's keep doing what we've been doing, to create thousand others problems to solve.
Fantastic video, as always! Just one thing though; let's stop using the generic term symbiosis when we really mean a mutualism, since commensalism and parasitism are also types of symbiotic relationships.
Am I the only one who found the hashtag #OursToLose in UA-cam's logo?
The Greatest Fallacy of Human thought is that we don't think Long term until it starts to get too Late
I gave a like and sub just for that Walking Dead bit
You lost me in the intro, Joe. Just because all life can be traced back to the oceans doesn't mean that it's not a coincidence that humans and the Earth's surface have approximately the same percentage of water.
+Ryan
You are right, but what is indeed no coincidence is, that the elementary composition of the average cell and ocean water are nearly identical. There are a few differences (especially Al3+, which is quite puzzling), bu the similarities are stunning and more or less proof, where life initially developed.
Guess the not a co incidence thing was just to show how natural water is to everyone, like oceans have 2/3rds of it and so do humans
somebody better save the ocean quick, we need a super hero.
Aquaemane
It sounds like each country represented in Paris will just be making a "pledge" regarding their own emissions, so why there has to be such an expensive conference I don't know. At least with pledges, countries can drop out one by one in the future when physicists confirm that force fields like gravity form an autonomous temperature gradient, so there's no "33 degrees of warming" to be done mostly by water vapor making rain forests 50 degrees hotter. The temperature gradient is already proven to exist with experiments with centrifugal force, so we're getting there, because gravity acts in the same way on molecules between collisions.

Wow you got picked up by pbs?? Congrats!
If coral is getting stressed, what is it getting stressed about?
Current events.
I'm so glad that this comment section isn't full of people saying climate change isn't real.
tbh, if you say you love science but say climate change isn't happening, then i suggest you stop saying you love science because there is overwhelming evidence in the scientific community otherwise.
Coral is an animal....
+Lyviiz did you watch the part where he explained that it's also a mineral and a plant?
Nesta4815 that's what I'm saying. It's not a mineral and it's not a plant. It falls under "animal." Read any biology book. Coral and sponges are the only animals that are asexual reproducers but they are still JUST animals. You can't be an animal AND PLANT. You are one or the other. Also, calling it a mineral is just flat out wrong.
+Lyviiz lol so you didn't watch the video. It's an animal. That has a symbiotic relationship with a plant. And it produces a mineral. So the coral reef is all three things. Obviously no organism can be a plant and an animal
Nesta4815 coral reefs are ECOSYSTEMS so of course they will have all three! He did not fully explain that in the video. He implied that the coral itself is all of that thing. Now kids who watch these videos will misunderstand and think coral is some sort of super organism.
+Lyviiz he mentions that it's symbiosis between two organisms. But maybe it is slightly vague for younger kids
Thumbs Up if you saw the UA-cam logo and quickly searched the hashtag on UA-cam or Google :D
Ohh...That's why UA-cam made a little planet next to the logo...
so if the sea takes in that co2 then could that explain why the fish are dying in the sea?
+angel ortiz
Yes because of ocean acidification.
news.nationalgeographic.com/2015/03/150313-oceans-marine-life-climate-change-acidification-oxygen-fish/
You know Carl died last night, there is almost some symbolism here lol
How about on fishing boats we have maps that show where coral is and if they go into the coral area that get a big fine like millions of dollars
And get people to back of from the ocean and instead of fished we can Breed fish on land or cut out a bit of the ocean to farm them plus make a team of people that name the ocean a country and if you enter the ocean you follow there rules
If CO2 contributes to the warming of the oceans and oceans absorb less CO2 as they warm, shouldn't that mean a gradual lessening of carbonic acid, thus, a reducing tendency toward so-called 'acidification'? What am I missing here?
But they have gone through so much through the years, why do this make a threat?
Those making fortunes doing business while destroying the environment must be pissed off about this campaign and UN's climate change conference.They would do everything do distract people from this issue...Where is the conference again?In Paris?
Coooooooral, there's a dead human in our house! Coooooral what did you do? Explain what happened Coooral.
where are his glasses at?
see, back then we were SEA OCTOPUS....now we are LAND OCTOPUS....in the future we will become SPACE OCTOPUS...
that's the intro song ?????
Mind blown 🖖
Climate might not change the sustainability of the corals in the Caribbean, being that it's subtropical, we have both cold and warm ocean water climate.
it would be interesting to see a video on animal agriculture and the catastrophic effects it has on our climate. No science channel is covering it and it's the most disturbing climate topic.
THE PUNS THOU
How do algae get ejected from their hosts?
+Tkbh 047701810
They don't latch well in high-energy (hot), acidic environments. Different enzymatic activity works differently in different salinity, acidity, heat, etc.
So, in short, it's complicated.
Why do we destroy our planet? D:
+Monst Because creepers
+Monst
Because we're hungry.
Hungry for more... of everything.
Modus Ponens That's good answer
+Monst Because 9/11.
Maprdr57 And in English?
I didn't really mean the whole "because 9/11" thing by the way. I was being facetious.
I read an article that invertebrates can actually adapt to ocean acidification.
www.livescience.com/7980-creatures-build-thicker-shells-ocean-chemistry.html
carbon dioxide is a pollution it makes acidic acid it dissolves Coral structures. then stuff like crabs mollusk shrimp cannot regenerate their shells when the water is too acidic calcification can not occur
THE JEW BELT
Dammit Carl!
You are a very cool person
Live long and prosper 🖖🖖🖖🏾
I love humanities hegemonic and megalomaniacal view of how the Earth should be after having only been here for a ridiculously short amount of time. Has science somehow determined that the climate of the Earth never changed until the dawn of man? Do the smaller plants hate the larger forests for using up "their" supply of Carbon Dioxide and filling the atmosphere full of oxygen?
+Jamie Hitt You've done an excellent job of attempting to not understand the problem. We're not concerned about climate change because the current climate is "how the Earth should be...". We're concerned because how the Earth is right now is a particularly good set-up for us because for the most part it's accommodating to our infrastructure, agriculture, etc. and we'd prefer to keep it that way, or at least not actively change it.
Ahuc899 I completely understand what you are saying and even agree. But the correct way of looking at it is that we need to affect climate change. We need to "change" the pattern or trend that is taking place. We need to "arrest" this development while our climate is still in a position to keep us all alive and happy. Scientifically speaking, I don't really care what is causing it. We only need to determine the cause(s) so we can determine the correct solution(s). We all agree that the data shows a pattern of warming and cooling across the timeline. We are in a period of warming. Human activity is slightly accelerating this warming. But the jury is still out on whether we can slow it back down or even stop it. Every intelligent human on Earth knows we are warming. The only question is how much of a role is humanity playing in this. It's the biggest nature vs. nurture example in history...lol.
Jamie Hitt I think you're understating how much we know about current climate change. You're correct that we are generally in a warming phase on the range of 1000s of years, but it's pretty generally well accepted that the vast majority of warming over the past couple hundred years is due to us (or at the very least there's no natural phenomenon which could explain it).
Ahuc899 Well, there's nothing like an industrial revolution and mass deforestation to knock things outta whack. Would be nice if the planet had some sort of dormant gene that had dealt with humanity in the distant past and could activate to heal itself...lol.
+Fenton Bevan He never argued againts it. But yeah one of the best solution. Although we have to be carefull. Cloud seeding, or dumping reflective particulate will have to be limited. If we increase the amount of light reflected into space over areas with large amounts of plant life, that could be bad. Also this will not fix rising acidity. Dumping iron in the ocean is probably one of the best idea.
It's a shame how so many people will drop great solutions because it does not look good. Nuclear power, burning waste, gmos, geo engineering, etc. These could fix so much.
At 3:50 they didn't say coral they said Carl.
Where is the next episode?
+Nicolino Will We're off this week getting ready for something BIG next week
