- Check out Sharks Unknown: • Shark "Traffic Jam": I...
With unprecedented heat waves and record-breaking global temperatures, it’s hard to believe that there might be a place on earth that has actually COOLED since the industrial revolution. But, it turns out, there is such a spot. The COLD BLOB off of Greenland mystified scientists for years, but new studies have uncovered a scary reality - this cool patch might be a warning of the impending collapse of a vital earth circulation system. And the consequences would be dire.
In this episode of Weathered, we travel to the Gulf Stream with the new PBS Terra show Sharks Unknown to experience the AMOC first hand. And we ask, what is the likelihood that the AMOC will collapse, and what would the consequences be?
Weathered is a show hosted by weather expert Maiya May and produced by Balance Media that helps explain the most common natural disasters, what causes them, how they’re changing, and what we can do to prepare.

We're just smart enough to screw it up, but collectively too stupid to stop screwing it up.
Nonsense. We have known exactly what kind of actions we can take to mitigate or reverse the damage. The problem is greed. The biggest corporate contributors to this problem would rather make more money now at everyone's expense now and later. This is how all mega-wealthy people think. With more money they think the problem wont affect them or their children, and they're right that they'll be in the best position to survive but their greed makes them blind to the realization that they will still need everyone else around them to make being "rich" mean anything. We could have started making progress towards these problems decades ago, but instead they've sowed doubt, discontent, and apathy.
@@JNArnold you're not wrong that greed is a large factor in this. But Tomtom isn't wrong in that collective stupidity plays a massive role too. The stupidity is sometimes in the individuals, for not understanding the science. But it is also in the collective, as in that we fail to transmit the knowledge that is available to the others in the system. It is further a collective stupidity because no individual can change the system on their own, with the best intentions in the world.
I fully agree with both of you, really. (apart from your point that Tomtom's point was nonsense, so I guess not fully...)
@@JNArnoldyou didn’t refute the op
@@mr-boo I wouldn't exactly call it stupidity (though I also won't fight the term). It's a psychological system to drive the masses towards the desired behaviour, regardless of what the individuals would want without this influence. It was developed during WWI, when the US wanted to enter the war but the US people didn't because they regarded it as a European affair. They called it Public Relations, and it was more effective than they could have hoped. In less than a year, people wanted to fight in the war. Post WWI, the same program was used to boost sales of private corporations, and a few decades later the NSDAP hijacked this exact system for their own political agenda - and if you can get a whole country to be on board with gassing millions of innocent people ... then what can this system not do? Today it is absolutely everywhere, every big corporation has its own PR office.
The worst thing for climate change is that it's exactly the fossil fuel corporations that are some of the most influential and wealthy corporations, and they try to keep their profits up as much as possible, damn the consequences. That's why they boost so much money into climate change denying PR and have so much success with it.
Time old story.
I live in Greece. December and January are usually the months with our heaviest rainfall. For the last two years we've had barely any rain during these months. Two, maybe three medium to big rains and that's it. I have been forced to irrigate our freshly planted fruit trees DURING WINTER!
In the early 2000's I was hitchhiking with a man who had a bunch of farmer friends in the south of France. They used to rely on spring rains to grow hay for next winter, the summer being too dry for such growing conditions. When I hitched with him he told me that all of his friends were seeing a shift in the weather patterns towards heavier winter rains and dry springs. This was one of many recent springs where they were forced to let their cattle graze the spring growth instead of baling it for winter, putting them effectively 'into the red' when it comes to feed production. They would all have to buy in hay for winter feeding.

I'm 71, born just after WW II. Of course I know my death is approaching - - as is global climate change.
I may have lived thru a "golden age" none of us recognized.
@@veramae4098 Many of us recognized, if you recall.
ClimTe manipulation???
Sounds like luxury, just 2 or 3 big rains? Not the 2 to 3 hundred big rain events Ive seen this past few months. So much rain its killed plants which is something ive never seen before in 50 years, you can always add more water but you cant take it away.
You start to lose hope when you know that so many smart people have been trying to solve this problem for decades yet nothing fundamentally changes and it only gets worse. 😔
speed up ...and let go what isn't to hold. "Hope for... reward" -> is a sick mindset. You know - one might expect reward from work.... The usual outcome of Hope is desperation. Nobody hears your prayers. Hug yourself as strong as you can.
Radical, desperate, and literal, bloody fight -- basically a global revolution -- is what it would take to change course, and even then it might be too little too late.
What is pretty sure though is that we, as a species, are not yet adult enough to handle a situation like this. Too bad, could've been such a nice story, with a little bit more luck...
its not a problem of knowledge. its a problem of political and economical will.
@@jamestbg8132 Some people (let's pretend not PBS itself...) couldn't even tolerate a previous comment of mine simply stating the obvious fact that meaningful (i.e. _radical_) global change would require radical change of behavior on a global level.
(Can't repeat what that -- pretty obviously -- entails, because it would surely trigger the same person(s) yet again.)
Makes you wonder "what hope?!" if you're only allowed to attack our hardest crisis ever with wishful thinking, and the same old feel-good, or at best "mildly concerned" narrative that has brought us so much... um, so much what? Lost time, and no improvements to speak of.
So, politeness is what will save us now, right? Well, thanks for that. Much more convenient, indeed.
@@lunakid12 Dont feed your ego. As likely it is you have right in theory, its known that you need to take people with you. Radical change allways takes victims and those who think it is necessary ... mostly turned out to be psychopaths or dictators. We are intelligent enough and we do know what to do, even without risking full clash of civilizations. Our problem are the idiots who follow the people who dont care about future generations and do care more about their own wealth and power, but all in all its the (by far better organized) minority.
My wife’s grandfather is a lobsterman in Maine. He has been doing this for 30+ years. He says the fishing has shut down this year.
98% of all snow and king crabs died off from a marine heat wave in the bearing Straits. It killed the crab industry!
Keep throwing garbage in the sea.
Your wife should be lucky its her grandfather... because if it was her father - or her brother - or you - or her son, they'd be in for a rude awakening over the next couple years.
Data says the Atlantic Meridional Overturning Circulation current is weakening faster than we thought. Europe is going to cool massively, very quickly, sea levels will rise, ice will melt, waters will cool marginally cool as ice melts off, locally, then temps will rise. These rising temps will impact lobster populations.
The lobster industry in Maine is going to end except for very regulated fishing. The populations will not support it.
It's not so much the climate CHANGE - both we and ecosystems can adapt - it's the SPEED in which its happening, reducing the ability for that adaptation.
We're not ready. Culturally. Politically. Or economically.
Buckle up.
@user-el5yw1er2j it'll melt then cause an ice age in the northern hemisphere. The earth will reset itself.
@@twincam103 Not in time to save human cold-water industries, bud.
What worries me about this? How difficult it will be to get crops out of drastically changing and/or unpredictable weather. No crops, no meals.
The Earth is greening.
Yeah, crop yields tend to increase with rising temperatures. Just look at all of history! The problem comes with a lack of moisture, which shouldnt be a an issue with warm sea temperatures, but climate is more difficult to predict than warm=better. So who knows.
Rising temps and rising crop yields have a hard limit.
Don't worry, the billionaires will eat just fine.
No crops, no meals -> WORLDWAR - of course. Don't stay naiv, bro.
I work in aviation. I have spoken with air traffic controllers who have, in some cases, worked at the same radar facilities, or control towers their entire career. Aircraft perform best into the wind. This is a fundamental rule of aviation. For this reason, runway changes are implemented to always be utilizing the winds to the best advantage. Crosswinds and tailwinds are not ideal, you want into the wind. The tower controllers in many cases have said, you know, back in the 80s, we used the XYZ runway configs maybe, 3 or 4 times per year. In some cases, it's like the east/west flows, where 99% of the time they're in a north flow, or similar. But they in some cases have said, well, now we run east/west flows half of the time we're operating...it's like, how can this be? Have the winds truly changed THAT much in just 20-30 years??? The answer is undoubtedly yes. When you hear anecdotes from everyday people like this, it really hits you, even more than the charts and hard science/data, IMO.
Thanks for sharing something I would have never even thought about! That's... an uneasy feeling.
I also work in aviation, with ATC and on the airfield at several locations around the world, and I have never heard of this. Magnetic declination changes, sure, but not prevailing winds. What you are describing sounds more like changes to traffic patters due to increased traffic over the last 20-30 years. More planes mean more traffic on limited air and runway space necessitating updated or new approach and departure procedures.
This only shows that there is considerable fluctuations in climate. Those fluctuations have always been naturally occurring.

In Japan, rising seawater temperatures are increasing the activity of algae-eating fish, leading to an increase in areas where algae are becoming extinct.
The extinction of algae has a major impact on the growth of marine life.

Ouch!
Ice ages are caused by the Milankovich cycle
Some have been saying it for decades.
im from Nova Scotia (near the 'cold blob') flooding has been insane these last couple years (record rainfall according to atlantic ctvnews). this year has seen 4x as many lightning strikes compared to the average of the last 20 years (26,194 in 2022, 6,266 average for the last 20 years. there is a CBC article but i can't post links in comments)
Sadly, the wealthy and powerful don't "believe" in data and science. Only their opinions and instant internet assessments count.
But it's funny you mention how lightning strikes are 4x as common, because that is *precisely* what happens when extreme temperatures collide under the right circumstances. There are already places on the planet that experience these kinds of "every hour lightning strikes", but obviously, no one lives there.
Maybe there has just been better measuring devices
I'm from Stockholm Sweden and we barely have winters anymore. This summer we have seen an insane amount of rain in a very short period which has caused massive flooding and failed crops.

30 years ago in school it was called the Thermo-haline circulation belt. Our instructors warned about the implications of it shutting down. It's a scary thing, especially for Europe.
i think its scary for all world. its just Atlantic ocean is more eemm important for research than rest of them. this will probably change flows in all oceans, everything is connected.
It's not shutting down. Don't be duped into any sort of panic
@@soakupthesunman Really, what makes you think it isn't?
@@jadezahreddine5379 Nobody has to prove it isn't shutting down. The onus is on those predicting it will shut down, to prove their claims. So far, every climate catastrophe prediction has proven to be wrong. ALL of 'em.
@@soakupthesunman But there must be at least 500 books that can be written and sold on that hype. Think of all the conferences and grant money colleges can get. Like the Roswell alien conference were all the rage, pre internet.
And they didn't even mention the Beaufort Gyre... a much more intense modification of the AMOC that will dump more fresh water than is contained in the great lakes into the North Atlantic. This usually happens within 1-2 years once it starts and can last for 20 years. It's a known northern hemisphere cooling factor. By not adding this to their story they've left out a huge factor that could cause that "2060" date to look more like 2025.
That's horrifying.
@@MWGCotah Exactly right! Unfortunately...
As a sailor I've been hearing people talk about losing the Gulf Stream and was curious about how that might happen. Thanks for answering literally every question I might have come up with about the subject. Once again you and your great team have hit a home run. 👏 👏 👏
Keep in mind the Gulf Stream and the AMOC are completely different things, when people talk about this collapsing and freezing Europe they are talking about the AMOC
@1ycan-eu9ji In the video the Gulf Stream was referenced by name.
The oceans need draining before they boil. Water Vapor (WV) is a greenhouse gas as potent as CO2 according to theory. On average there is 50 times as much WV in the atmosphere as CO2.
The fact that it is non -persistent is often mentioned. It doesn't have to be. You can AVERAGE (integrate) the effect. There is on AVERAGE 50 times as much.

@@msimon6808 Maybe you don't realize that as the atmosphere warms it can hold MORE water. That is why CO2 acts as a thermostat. Increase CO2 (GHG) and it will warm and then more water (GHG) will enter the atmosphere, ... Yep. CO2 is the culprit. Thanks for pointing it out.
Love the way you broke down the word thermohaline for folks without getting pedantic. Getting folks who are busy with other concerns in life up to speed without getting condescending is going to be key as this all gets more complicated and intrudes into everyone's lives. Well done, as usual. Weathered is a really, really great series that brings fairly detailed science in a way that's understandable to the general public. Thanks for all you do!
Too bad it took 30 years.
2011 was the record low polar ice. The ice ages cycles only started when north and south americans join toguether, blocking the old world stream more centralized like in pacific and indic. So this atlantic shape, creates a piston movement on the stream that creates the cycle warm - cold - warm - cold of the north atlatic and polar oceans, afecting the rest of the planet as well. If you watch closely, its only the north pole that are trully warming up, and not the south pole. The atlantic piston cycle. ;) (just a wild thinking that i had 6 years ago)
Just wanted to give a counter point of view after talking with some climate scientists/oceanographers who study the AMOC directly (shoutout to Dr. Penny Holliday!). The Ditlevson & Ditlevson paper is really the only recent one that is predicting AMOC collapse this century (with a 95% confidence level which in of itself is suspicious given the unpredictably of chaotic systems like an AMOC collapse). The IPCC estimated it very unlikely to happen this century based on the scientific consensus (single digit percent level as Rahmstorf hoped). The disconnect comes from Ditlevson & Ditlevson using a novel (and controversial) analysis technique. North Atlantic (NA) Sea Surface Temperature (SST) has been used as a proxy for AMOC strength before and the usual protocol is to subtract the Global Mean SST to take out seasonal variability and the direct impact of global warming on SST. To account for polar amplification (more warming in the Arctic relative to the mean), the group subtracted 2 times the Global Mean SST from the NA SST instead. This has the effect of exaggerating the variability and decline of the AMOC and is what gives you the downward slope graph shown in the video. By just subtracting the 1 times the Global Mean, you don't see this decline. The paper also neglects to include any of the direct measurements of the AMOC strength that we have been taking continuously since 2004. The measurements showed a slight decline in the 2000s but the AMOC slowly grew in strength in 2010s (likely just due to natural variability).
This is not to say the paper is wrong. It's a very sophisticated analysis for the most part and can still tell us some interesting things. But the science on AMOC collapse is in no way settled. We have to wait and see.
This is also not to downplay the importance of an AMOC collapse. If the paper turns out to be right or if we don't bring down emissions this century, an AMOC collapse would be absolutely devastating for the exact reasons outlined in the video. All in all, an excellent video and an important discussion but take it with a grain of salt. (shamelessly replying to the top comment to increase visibility lol)
Are they talking about the Gulf Stream?

What's scary is that the governments of the world know about this and they aren't doing nearly enough to make change
The government doing something can only make it worse. And there are governments working closely with powerful and evil people who are using this climate change to scare everyone into total submission. Dont be one of them.
There are no governments. There are corporations.
Gotta get those gains. Its truly what will be our demise. Capitalism and greed.
@lailahreich3205 The crazy thing is people consider humans to be so intelligent. Its not a very intelligent move to know what you're doing is terrible and bad for your survival, yet continue to do it. No other animal on this planet would do that except for humans, yet we're so smart.
You trust either government of companies to sale an actual solution to this when they can just do their ESG BS to give off the appearance of it??? 😂😂 cmon now.
Instead they create the crisis funded by your money and sell you the solution
My biggest concern is the regional variation of global warming. Too many pundits talk about global temperature instead of regional changes. It is well known that the southern hemisphere and the tropics haven't risen anywhere near as much as the higher latitudes of the northern hemisphere especially the artic. In the artic tundra the permafrost contains as much methane hydrate as all the fossil fuels burned in the last 150 years. If methane is released from the permafrost it holds more atmospheric heat 20X, than co2, as much as water vapor. I've never seen a timeline on how much temperature rise will release how much methane. Back to regional variation. Most of the worlds ecosystems/ vegetation zones have a huge shift in seasonal rainfall with dry seasons being part of the cycle. Agriculture depends on these specific rainfall patterns. We in the US especially east of the Mississippi have more moderate high and low range.. The other fear is for Asia. 8 majors rivers come from snow melt of the Himalaysian mountains. If there was only a 20% drop, China, India, Pakistan and Southeast Asia would suffer lower food production. But like you said changes in the AMOC is also a big threat.
I don't know if you knew this but the big concern if AMOC slows a lot is that it might well alter the tropical monsoon, possibly reducing rain for India & Southeast Asia. The cooling of Europe is more certain but the tropical monsoon possibility would have more negative effect than a couple degrees of Europe cooling, if that monsoon change does happen and reduces the rain on land.
Having been a small fruit grower - blueberries, raspberries, blackberries, elderberries, highbush cranberries, gooseberries, plus a wild grove of mulberries - I have watched in 20 years a shift of a full hardiness zone in our area. The problem is that it's not a "clean" increase, we still get oddball very late freeze events in spring that two years ago caused a LOT of my fruits to have substantially decreased yields, both due to freeze damage and it being too cold for pollinators for nearly two weeks right in the early spring blooming season.
Plus I've seen an increase in various insect pests, and a massive and unpredictable increase in fungal diseases. It's going to be worse with forestry and tree crops, as these changes may mean that you have a disease or pest that suddenly invades areas with mature trees, wiping them out. For example, they found out that cold winters can massively reduce emerald ash borer populations, but we've had enough warmer winters that even the Great Lakes States are getting hammered. Ash trees may become extremely rare in the United States due to this.
So this is a huge problem. I cannot understand why so many farmers are voting for politicians that are blocking any steps to deal with climate change, because whether it's farmers in the Colorado River Basin (20 year mega-drought that may just be ending, though it's more likely a reprieve not a pardon) or farmers having to plant more southern varieties of blueberries that are inferior to the more northern ones in taste, but can survive extended heat waves better (look up Rabbiteye versus Northern Highbush Blueberries), farmers can see climate change in action over half a lifetimes of farming (20 years).
As an example of how devastating this can be to farmers and crops, it's not just having to change Blueberry species, but you end up pulling up or losing mature bushes that could have lived 50 years and had over 20 years of optimal yields, and the new pushes can take 5 years to return to full yields. Assuming no drought, because freshly planted/younger bushes have less of a root system, and are more susceptible to water shortages. Look how devastating a workplace injury or layoff that causes a family to lose months of income can be - and then consider surviving a five year financial hit.
There are dozens of other examples, and it's not just in the United States but all over the world agriculture will require massive, rapid changes to cope with this. Then when you have overpumping of aquifers, like in the Colorado River Basin, you end up with a collapse when that water becomes prohibitively expensive, if the dry period continues.
Look up "food riots". Drought and famine have been events that have ended civilizations. Plus famine gives you more disease, and nations go to war to make sure "their" people don't starve. You've got all four horsemen covered...
I couldn't agree more. Problem is also that farmers or farm companies are also big poluters and industrial farming is responsable for too much poluters on planet (people).
We need to lower population in soft way or nature will make it the hard way.
Plus we need to go on sustainable way of production of food and with all other industries.
But this will not happen until gloriefied capitalism is rooling the world.
@@ueasy1actually, due to aging populations across most of the developed world, scientists are now predicting that the the global population will reach its peak and then begin falling around the year 2050.

Even dogs are smart enough not to poop in their own food bowl (but not humans). Perhaps we should put them in charge for a while... It never ceases to amaze that greed and stupidity are at the heart of almost every one of human kind's greatest challenges.
I will forever remember my Ecology 101 professor in college way back in the early 00s discussing this system and our impact on it, and telling us that every major disruption of the thermohaline circulation is strongly correlated with mass extinction events.
The whole classroom gasped in recognition of just how dire this is, and went silent.
My high school AP physics teacher did a thought experiment like this that left the whole class shaken.
We were calculating the energy input required to phase change ice into water, and then what the water will end up temperature wise with that same continued input.
He applied it to the real with with the artic sea ice, and the arctic sea. The amount of energy we're putting in to the arctic *currently* that's melting ice, increasing the albedo of both water and land, and releasing additional greenhouse gases from the thawing tundra.
Point is, the Arctic ocean will be a balmy 40°C, based on those rudimentary psychic equations, and not including any of those other inputs i listed above.

@@TheKamahl07 But, if all of the ice melts, won't your beach property become submerged?
This is also one of the things I strongly remember from Ecology 101 in the early 00s. It was terrifying then and now it is just mind numbing that we are actually approaching this event.
It also means the record warm oceans we are seeing now will get exponentially hotter as all that tropical heat will have no where to go. If the oceans die the land dies.
Massive global release of billions of tons of methane will see to that. Another Permian mass-extinction event.
Add the El Nino to the record heat in the oceans then we really in trouble!
And then we get ultra strong hurricanes and the world is f**ked!
There is no excess heat! Just excess stupidity and lack of education!

I fear the younger generations. We're leaving them a mess and a much harder life than we've had.
Its even worse than that, we are dooming human civilisation to collapse within the lifetime of someone born today.
Nah. We are about to be overtaken by a.i. biggest change in human history ever. Bigger than the discovery of fire. They will be fine.
Very good. A lot of sceptic don't understand that 70% of the ice in antarctic is fresh water and 70% of that sits above land. So two things contribute to sea rising. Fresh water floating on more dense salt water and ice above land is straight addition rather than displacement for ice floating

Stefan Rahmstorf is one if the leading scientists working on the AMOC so I take note of what he says. The paper sighted at the end with it's alternative explanation for the Cold Blob does not account for the marked rise in sea temperature off the US East Coast which models predict for a slowdown of the AMOC.
Hi Pete, good points here. We really felt that a nod to the evolving nature of science was important. Stefan is featured heavily but there are peer reviewed papers that disagree with his findings and that's part of a healthy scientific process.

Climate migration leading to conflict is the most worrisome in my opinion. Subsaharan Africa, South and Central Asia, China, and parts of Europe are likely to be far less habitable. This amounts to more than 25% of the global population. We humans are not very welcoming to migrants now and the numbers are nowhere near what they will be in 100 years.
Climate migration from state to state will happen here. The Midwest will become inundated with climate refugees from coastal areas and the hotter southern tier of states. Where will the breadbasket grow traditional crops with the influx of that many people? We are going to have to get over our fixation with beef, wheat and corn and start growing crops that need less processing, less space and less intensive farming practices. Field corn is really of little use as food without turning it into cattle feed, corn meal and corn syrup. It is too low in nutrition to feed us as is. Refined white flour is labor and space intensive to produce. Cattle simply take up too much room and too many resources, as well as releasing a lot of methane. We will all need a vegetable patch and a few chickens scratching around if we survive the collapse of the ecosystem.

The prospect of Scandinavia becoming 8 degrees cooler than it is now-that’s scary.

@3:04 I was obsessed with that movie all throughout middle and high school. It's scary how that movie seems to become reality to some degree the more time that passes and still 20 years later, haven't changed those old habits, but rather embraced them and made things even worse now than then.
12:08 we're actually here in the Gulf Stream where a lot of sharks gather.
... precedes to jump into the ocean and swim
As a Dutch person I am used to mild weather in general, mild summers, mild winters. Although when I was a kid in the 1980s the winters in my country were much more harsh than these days. People here love ice skating on natural ice. This has been done for so many years on canals, lakes and even rivers at time. In the province of Friesland, if weather conditions allowed, we organized a 200km ice skating tour across 11 cities (also known as the "11 cities tour", or "Elfstedentocht" in Dutch. The last time we could do this, and the whole country was sitting in front of the tv watching this event was in January 1997. So imagine, it has been 26 years ago that this thing could be organized. The only plus side of the Gulf-stream slowing down or stopping is that we would be able to skate more often. But in general I doubt it will be good for Western Europe if this ocean cooling/warming effect will diminish.
deze fenomenen is niet zo speciaal, aangezien het vroeger gebeurde maar de mens nog in haar prille begin was gaat men nu moord en brand schreeuwen ofzo? kom zeg! als ons voor ouders dit konden overleven waarom wij niet? hier moet ik hard om lachen! de mens en hun luxe leven is in gevaar! 🙄🤑
Wow! That city tour must have been fanstastic. Here in Ottawa, Canada, we have the Rideau canal. In the '80 we could skate the whole 7 km until we arrived at Dow's lake. In the past years, there is only a small stretch of ice that they can open to skate as it requires constant waterings to try to make a safe thickness, and year after year we see the number of ice skating days diminish. In 2023 I think it was open 11 days. We are losing this wonderfull winter fun.
Interesting story. Thank you for sharing it with us. I have a pond in western ny. 10 years ago it froze enough to skate, but I haven't been able to skate in the last 5 winters. The weather is definitely changing. Climate change occurs over thousands of years so its impossible to tell yet.
I don't think it will get colder like they said, the tendency is actually to get hotter if you look at other interglacial periods of earth history, especially without the artic ice cap. The higher latitudes should expect temperatures to rise really fast in the next few years. Your testimony only confirms it. The climate will be similar to earth 3 to 4 million years ago.
@@TheNewCarryTrade no you are demonstrating the Krueger d u n n i n g effect. Humans are causing the rapid warming of the planet with tremendous amounts of carbon dioxide emissions add roughly 37 billion tons of carbon dioxide emissions per year third year after year after year after year after year. Was becoming less pronounced as the global population was smaller requiring less and less energy every year energy comes from the burning of fossil fuels planet Earth is actually in a greenhouse gas mass extinction event you may not experience the ferocity the storms in heat waves and drought that your children and grandchildren will experience. A high emissions scenario by 2100 will only leave 1 billion humans how to survive on planet Earth. Most humans between the Equator and the 36 chicory latitudes will either die off or migrate North there will be a huge complex over extremely short Water Supplies or famine. This is the reason play all carbon emissions need to come to a stop or at least reduce the output to a level that all forests and all oceans can absorb safely. But I'm not hopeful that's going to happen
thank you for clarifying that the AMOC =/= the gulf stream and that if the AMOC slows the gulf stream won't disappear (unlike some recent clickbaity news articles)
Yes I agree! The confusion between these things has led me to question the source of the news
If people in England or Scandinavia worry about the Gulf Stream, they aren't thinking about the direction of water surfacer flow in the North Atlantic, they are worried about the warmth it brings. The people who have complained about "AMOC ≠ Gulf Stream" have been more clickbaity than the articles they have criticized.

It was sad the day my father got rid of his lobster boat. He still digs clams and hes almost 70.

@@shiningirisheyesWhat is fascinating to me is how efficient all these underwater volcanos are heating up the Atlantic Ocean, the Indian Ocean, the Arctic Ocean, and the Pacific Ocean at the same time. And it's crazy how they are all so silent like sunshine, no big explosions or earthquakes or magma flows or steam or anything. It's crazy too how those underwater silent volcanos seem to be making air temperatures even hotter than the oceans.
I love when scientists just say fuck it and name something “cold blob” 🤘🏼
The AMOC slowed about 600 plus years ago and Europe suffered with extreme cold for about 450 years. 1400’s to the 1850’s Europe was much colder. Rivers froze and crops died. Everything is so intertwined. Colder, warmer, wetter, windier, and drought are all considered climate change. Climate stability is what has let us flourish for 50,000 plus years. Climate stability is not part of our future.
We’re sitting in a place where sharks gather…
Ok we’re in the water 😕🤨
That cold spot could be the stagnation of the water currents in AMOC. When currents are moving the cold water gets pushed around, but when they slow down the cold water stays in place and gets colder and colder.
Well that's exactly what it is of course except that "stagnation" isn't really the word that's used (same concept though). The water flow has slowed like you said so some more heat is staying to the southwest (you clearly see the Warm Blob) instead of flowing up to the northeast and warming the Cold Blob as fast as it used to. That water is simply running down hill of course (well except that 85% of it is wind driven, unrelated to AMOC). The bit running down hill is filling in the dents left by the deep water heading south of course.
Wow, thanks for repeating exactly what the video says!
My only question about that is why is this happening when thermodynamics dictates that if anything, that blob should be warming like everything else. The cold water should be trying to spread out underneath the warm water rather than pooling up in one place.
Don't get me wrong, I'm not denying that this is an effect of increasing global temperatures. I'm more just kinda confused by it, since it kinda defies physics. Ocean currents are driven by convective processes, so if you add more heat to the hot side of the system if anything it should intensify, as the heat is trying to move into the colder areas so that the system can achieve homeostasis. But this is the opposite of what we're actually seeing.
@@VestedUTuber….as ice from Greenland melts, the meltwater is freshwater and less dense than the sea water so it floats on top of the more dense sea water. This cold water patch is amplified over time and eventually slows the transport of warm water from the south. Eventually, this can result in an Ice Age. This is explained at 4:20.
@@desertsky9886
Except that freshwater doesn't _stay_ freshwater, it eventually mixes with the seawater, and quite quickly for that matter. Plus, if it was just sea melt, the cold blob's concentrations would be at it's highest around Greenland's coastlines, particularly in areas where there are actively melting ice shelves. Instead we're seeing it primarily concentrated in the middle south of Greenland's southernmost tip, so either something's dragging all that freshwater into the blob quicker than the ice is actually melting or there are other factors involved.

Remember who did this. When you’re hungry, eat the rich
Ice core samples do show that just before the last Ice Age, there was a warming, that became a "run away warming" and then suddenly, the temperature dropped by as much as 6º within two years, then it rose again, up and down, extreme highs to extreme lows, within two or three years. After a few cycles, less than twenty years altogether, the temperature dropped drastically and didn't came back up again, until the Ice Age was over. It was theorized at that that the warming had caused the collapse of the ocean currents as you have described.
That was the theory that was pseudo used for the movie “day after tomorrow”. They of course bastardized it but still
Ask I pressed submit, she mentioned the movie lol
I suppose pre ice age man cooking their sabre tooth tiger steaks were to blame for global warming prior to the last ice age.
If you look carefully at the graphs from ice core samples that show temperature, CO2 and methane, you will see that in EVERY CASE where there was a spike in temperature, the first thing to rise was not CO2, it was Temperature, followed by CO2.@@stevenhull5025
I have been reading everyone’s responses till I came across your comment. Finally someone who I can agree with because it’s so true.
If you look carefully at the graphs of ice core information that shows temperature, CO2, and methane, you will see that every time there is up ward movement, it ALWAYS begins with temperature, followed by CO2, and then methane. I think the Sun is the primary driver. It is well known that the more sunspot, the more energy the sun is putting out; and that the "Little Ice Age," as its called, from 1300 to 1850 AD, was the result of the lack of sunspots, that is now called the Maunder Minimum. We are now in a sunspot cycle that was expected to be on the low side, but is much higher than expected. @@kennethsnyder9236

Living in one of your “riskiest regions” of the u.s. I have a front row seat to climate change, yet we are continually amazed our neighbors and politicians can deny anything is amiss. We can no longer deny to ourselves that we need to leave for our health and quality of life is suffering even though our income is tied to the area as well as our families. My anxiety cannot take hurricanes, floods, tornadoes, drought, heat domes, power failures, and now wildfire especially in our elder years like we are now. This is getting worse each and every year. I have actually encouraged my grown children to escape if they possibly can because I love them so much. Escape will be harder and harder as time marches on there will be nowhere to go but staying here is not an option.
I feel for you. I am 61, but I am fortunate enough to be in Michigan, where the impacts of climate change are not as bad.
Where do you want your kids to escape too, so I can send my kids with them I am 63 so by the time 2060 arrives when the AMOC stops I will be long gone but my daughter and especially my granddaughter will be here to face the collapse

Global warming is happening so much faster than ANYONE wants to admit. For anyone today that has young kids consider them the last generation survive on the planet. We have 50 years max but realistically its going to be more like 25 because in about 10 years time the amount of warming will have gotten so bad that runaway effect will have increased so much that about 10 or 15 years after that the earth WILL have become unlivable to the point that unless you are living underground you would not be able to survive. With everything that is going on in the world today and the fact that WW3 seems to be right around the corner, I have come to the sobering reality that maybe this particular planet and its species just wasn't meant to make it.
Human beings are corrupt animals anyway. We want fairness but every system and every avenue of prosperity leads to total corruption
My concern about this situation is that whilst the media and governments play lip service to change, they're ultimately more concerned with profits, which drives consumption, and so far from seeing any changes in emissions, we see that year on year they rise.
It’s not just politicians, everybody is paying lip service to it. NOBODY is prepared to change their way of life; the only way is for the world, meaning globally and in unison to change - because some won’t do it while others do not; people are too selfish in that regard and won’t sacrifice unless everybody does.
In the UK with Covid restrictions, the law was changed and people followed it. Only with laws, regulations and enforcement will people change because we need to be made to do it, we are too self centred to do it ourselves.
I agree, but without leadership people won't change, they might resent and oppose it, but it's simply not happening; and in the meanwhile yet more oil rigs and coal mines are opened, I never realised until recently the scale of coal mining and fracking in the US, let alone China, (who everyone loves to pass the blame onto.) Year on year more things are unnecessarily wrapped in plastic, almost all clothes are made of nylon, people have little choice in these matters, and it's all to benefit oil companies. Not that even they will ultimately benefit, but they're too blinded by greed and power to see their own evil stupidity, so they, with complicit media and governments keep the people as ignorant and stupid as they are.@@techyd8411

This area is colder because that is where all the icebergs start out when they melt off the glaciers in Greenland.
That's why it's getting colder as the melting is speeding up.
The earth "just" came out of an ice age! Temperatures fluctuate. Expecting the earth to maintain the same temperature is crazy.
I have found evidence (unpublished) that the 8200 Yr Cooling Event was part of an unexpectedly complex series of events which included a 110-year collapse of the AMOC. More recent research shows that in Northern Ireland that collapse caused rapid outcomes including cooler than 0°C every month of the year, beginning immediately after... most likely making all of northern Europe uninhabitable in those times. No crops, no leafy trees for mammal foraging, etc. Scientists should evaluate the surface current coming down the Davis Strait as a potential forcer.
I realise you are a US company but it would be great to cover the whole world, including Southern hemisphere in your maps/predictions. We're concerned about this in Australia as well. I particularly wanted to see about the monsoon belt dropping but Australia was cut off the map.

Hi PBS Terra, thank you very much for doing this detailed and coherent video, this style of presentation satisfies my desire for consistency coherence and logic, that subtle combination of hypothesis and evidence, those complex relationships between the many conflicting and contributing factors, elements and forces.
Given that the two primary forces, heat and gravity, interact in global dynamic systems with materials of differing heat capacity and density a high level of complexity is to be expected and so accurate predictions very difficult, what cannot be contested is that there will be significant changes in global climate and there is a history of such changes are sometimes dramatic. Calculations of temporal probability are really of academic interest only, knowing exactly when these changes are occurring is more than enough for us to respond appropriately.
Cheers, Richard.

It’s all about controlling your money, what you think and where you go and how to still more of your money.
I think that an AMOC collapse can lead to a serious reduction in phytoplankton growth, because of ocean water stratification preventing the upwelling of nutrients from the deep. Not only are phytoplankton key producers of organic molecules - food for organisms at higher trophic levels (e.g. for the fish we eat) - in the ocean biome, but they are also responsible for about 50% of the oxygen production on Earth!
I find troubling that it's a constant reference to emissions. I find more intense heating without a commensurate cooling due to rapid development of cities, deforestation, development by means of defacing natural spaces instead of 're-development' (removing and rebuilding in existing areas). Case in point is the massive growth of Texas cities which are linked by air and massive highway systems. Ranches and green areas being stripped bare to add apartments, concrete and asphalt pads and so on, plus add all the air conditioners compressors/heat pumps running all day and night- the heat domes are just like those on top of a computer's CPU which require massive cooling systems. Computers have those our our cities don't. You can cut emissions, but politicians and citizens need to come up with a better way to accommodate human growth/housing and commercial construction. They typically won't until 1) it's a crisis and 2) not on my watch/pass it to someone else. Even Chinese cities are at record temperatures more than ever before- and its not cars- it's massive, heat-retaining/heat-producing sprawl.

There also is going to be a effect this winter. Even today there is smoke in the air from Canada. Black absorbs heat. It also radiates it. IN 31 days Anything above 45 Degrees latitude will radiate more heat than it absorbs in those huge tracks of burn areas. Those areas are down wind from The Bearing sea and the Gulf of Alaska. So might get colder than -40 in Yellow Knife this winter.
Why no F or C? -40 is the same on both thermometers.
If it dips into the Great Lakes. Those will freeze over. All of them? Then then the ice breaker will be working non stop next winter.
Climate change will cause immigration, or climate refugees, to move from the hotter regions to the cooler regions. The real question no one can answer, how will climate change affect food production?
Not just hotter to cooler, also cooler to hotter. At least 500 million people will need to move due to going from mild to near freezing down to below freezing temps, and those already at below freezing will likely need to move closer to food sources as the sea ice will become even thicker which will cut off the northern territories from their current fishing and hunting regions. It's not clear in this video but the "comfortable" habitable belt will shrink by 20-40% very quickly after such an event, and it's highly likely that the belt will be split in the middle by immense heat.
Food production is probably the easiest thing to guess at, most regions will need to change their crops, animals and production chains, many will no longer be viable, specifically in the centre of that previously mentioned belt, but also the northern regions. Global food production would probably be cut in half for several decades unless we do massive ecological engineering projects on scales we have never attempted before. This likely wouldn't matter too much though as people would be moving closer to food production anyways, one of the biggest issues right now is just getting the food to the people that need it, starvation could be completely eliminated if we could just manage food transportation and waste better.
It’s been answered many times. It will effect a LARGE amount of crops, many crops we know and love gone. And so much land lost.
dude this is perfect, all going according to plan
well any crops that are sensitive to heat will need to be grown somewhere else and you will have less land near the equator to grow food
well…to the point of starvation. it’s not even a « future » consequence, it already started many countries are facing extreme shortages, a lot of people have died from starvation due to the inaccessibility of food and water due to cost or insufficient supply.

Biggest fear is the connection the AMOC has on other key tipping points. Aside from the cooler northern hemisphere, it's not going to stop overall global warming, in fact given the statement about the carbon sink, it's going to make it worse. Potentially much worse. In other words, the AMOC could be the lynchpin tipping point which locks in the rest.

There's strange things afoot on all the other planets in the solar system too.
Thank you for such a clear exposition
"that's why the process of scientific discovery and debate are so important" - except when we talk of COVID and Climate Change. Overall a very good report. Thanks
I am so pleased you were able to collaborate with the shark study team. My daughter and I watched that together. Climate collapse is a little heavy for her age group, but we share what we can.
Terryfying your kids is not a good parent.
good for your kids, the climate isn't going to collapse. climate rolls in cycles.
follow the money to see who is giving them out their agenda and surprise
Ignore the climate deniers. You're doing good, you're preparing your kid. Remember, if we don't do something, things will get much worse than just watching a video.
No one is denying the climate is changing. We all know the causes are multivariant and no reasonable person can point to anthropologic interference as the reason as the climate has always changed, and will continue to change. My point, and others are that there's no point living in fear or feeding fear to your kids. The earth isn't going to die, the oceans aren't going to dry up and regardless of this video and many like it the world will be find in 12 years, 50 years and a hundred years from now. Just as it has always been. Its ok to think critically about the agendas you chose to accept. @@FelipeKana1
I live in Germany and really prefer not to experience Canada like weather, as my latitude actually should experience if it weren’t for the warming effect of AMOC…
Time to move to Western Canada eh!
@@d.g.rohrig4063 There's only so much room on the northern west coast of North America, and they also have much bigger forest fires than here in Germany.
but there still is the warmer temperature in general, in summers it might not get as cold. also, i prefer colder winters (not wantig to say that I want the amoc to collapse) because then finally some of the thermophilic neobiota and neophytes don't spread here.

Is BC still burning?
I'm just happy two sisters are telling part of this story. Intelligence over beauty.😊❤
I'd love to hear about impacts like this on pacific regions.. I'd love to hear about impacts like this on pacific regions..
Too little too late i believe we have already tipped over the edge. The poles are shifting which i think will cause extreme winters and summers. Its 110 f in Texas we are burning up down here we got phoenix weather which is crazy.
If only humanity were a more intelligent species.
About as smart as yeast in a bowl of sugar water. :D
Intelligence isn't the problem, empathy for others is.
And more empathetic given that without basic welfare people will never switch from cynicism to environment awareness
@@markmuller7962 Exactly.
@@Someaddress555sintelligence and empathy coincide because it takes critical thought to imagine yourself in other people's shoes.
The most obnoxious thing about climate change is that it's an incredibly easy, damn near effortless problem to fix, but we're so obsessed with fossil fuels that we just can't handle the concept of a world without them. Humanity is soooo fucked, and I am all here for it.
This is the scariest thing coming. Around 11,000 BCE an ice dam broke and flooded the Mackinsey River in Canada with a Black Sea-sized lake of Laurentide glacial melt. The Mackensie carrlied that north into the Arctic and then ocean currents took it down past Baffin Island into the Labrador Sea, disrupting the AMOC. This started the Lesser Dryas, many centuries of ice age, a reverse-course when the world was warming.
Thanks for a very intersting explanation. What totally astounds me, or perhaps it should not really) is that despite all the overwhelming evidence that we ALL can see before our very eyes there is STILL nothing being done to change our part and there are still "experts" arguing that the evidence "may not" be proof of the trouble ahead...... . THAT IS THE TRULY SCARY aspect of the whole situation. The Naysayers say Nay and they hold sway..... but very VERY soon the Itoldyousos will have the last "hurrah" as we all go down with the sinking ship.
Now we need a study very quickly to see what the current year of 2023 massive forest fires around the globe have done to CO2 levels all that solid carbon of which Trees are made has been released in one very hot summer and is still ongoing.......
Yes except Trees aren't made of solid carbon of course. Also, the big issue isn't what you, and everybody I've seen or heard except me, keep parroting about. They're both issues but the big issue, at least for my country Canada, isn't the wildfires adding CO2 in the air but rather the Sun taking CO2 out of the air and putting it into trees more than before. Where on Earth do people (except me) think the FUEL for wildfires comes from ? I'm listening in disbelief to fire chief "experts" saying they can't understand why wildfires burn fiercer, hotter, than before. When a vast amount of carbon from 300 million years is put into the air ready for the relentless Sun to convert it into wildfire fuel then what on Earth did they expect to happen ? Nothing ?
oh I know trees are not "solid" carbon. I should have made that clearer maybe. It does not really matter as there is a far deadlier, silent, tasteless, odorless and invisible to you or I, threat to all life on our planet that has spread to 97% of the entire world or maybe its actually 100% but the media have not mentioned it.... yet.
Canada a beautiful country and a place I wish I lived @@grindupBaker
