Abrupt global ocean circulation collapse. Time to start prepping?

- An abrupt collapse of the Atlantic Meridional Overturning Circulation, or AMOC, was the plotline for the 2004 hit movie 'The Day After Tomorrow'. Thankfully the apocalyptic scenes depicted in that film are not going to happen, but the AMOC system has been weakening for decades and it is likely to grind to a halt at some point in the not too distant future, with profound effects on our planetary systems. So, can we do anything about it?

You should revisit this video based on the report we got this week about the AMOC collapsing sooner rather than later
it was just moved up again in the paper titled "machine learning prediction of tipping and collapse of the atlantic meridional overturning circulation"
There was not a single collapsing AMOC INTHE LAST 13999 YEARS.

This triggered a memory of a snot nosed kid version of myself raising my hand to ask one of my favorite primary school science teachers; is it possible that ocean currents and temperatures could affect the flow of magma beneath the ocean floor like they do with the weather and winds, causing earthquakes and volcanic eruptions? My amazing science teacher looked like she was getting teary eyed. Looking back, it probably made her day.
Most likely teary eyed because she doubled as an English teacher and you didn't know the difference between "effect" and "affect". Or perhaps you sang your question and she was a music lover.
@@grindupBaker That was unnecessary.
Cool question, especially for a young kid!
More Salt, less density.
@@grindupBaker like knowing you're shit vs knowing your shit.i guess. You know?
That has always frightened me upon learning about this in the late 80’s in my geo-studies. The other big scare was learning about how much methane, and the potential of release with more warming of the arctic tundra.
The Nordstream pipeline blow up and the fragmentation of plastics is also a big source of methane
We need the aliens technology and we need them to tell us what we need to do we need their help, maybe this is why they're trying to force disclosure. I don't know but I do know that it's all true what they're saying about the aliens and the secret space program. Because of 1969 when I was only eleven years old and living in Roseville California I would see them anti-gravity craft come up every night on maneuvers look like they were training for something they were very organized I wasn't the only one who saw them in my neighborhood they were very high up though like satellites but it was definitely anti-gravity craft that could travel several thousand miles per hour and as I watched them for four whole years and they had two nights off per week they increased from thirty-five to forty up at the same time I kid you not I'm dead serious. I have never forgotten what I saw those many years ago then my father took a transfer to Houston and I have never seen any in Houston but I have heard others say they have seen them seeing is believing.
Should have been around in the 70's, when I was worried because scientists were worried about the upcoming ice age, which didn't happen.
@@retiefgregorovich810 well, I also remember that prediction but the methane makes co2 look like a child’s Chemical playset. Regardless, we’re all in for a ride and consequences. If what you see as normal in your 50-60+ years, then you’re not paying attention. Ice age was a planetary alignment which should have snapped us back into cooling. That worked in a pre-agricultural world. It’s no longer the rule with all the driving inputs. I know, I know….yammer, yammer dooms day.
@@retiefgregorovich810 this is what they were talking about. In the 70s we just know more about it now makes it worse.

"There is no way to prepare to survive on a dead planet.'- Guy Macpherson.
Macpherson is a loon.
“If” it has happened before, it isn’t due to “ human activities “ ( even though they “may” accelerate the process); it’s obvious that there isn’t nothing we can do to stop it! Nature is the Master.

I wanted to take a moment to express my sincere appreciation for your video. It was not only informative but also incredibly engaging. Your passion for the subject matter truly shines through, and the way you present information is both entertaining and easy to understand.
This has been eye opening! Thank you for sharing this! I am definitely looking forward to your next post
Fascinating. Thanks for the information.
May I say that your delivery has become far more casual and realistic since I first began watching you.
Anytime someone starts a sentence with fascinating I then have to read it in Spocks voice lol
So the delivery has become much more casual and realistic. I've not heard him before but I can tell you he could also sound authentic if instead of reading from a script at a rate of knots, he were to speak from the heart at an intelligible speed which gave the listener (there's nothing to view) those vital moments for the meaningful assimilation of such important information.
Is it possible to play this video at a slower speed?
Thank you Vivalaleta. I appreciate your feedback :-)
@@tdowl Just click on the gear at the bottom of the video and pick whatever speed you want from one quarter speed to two times normal.
It's better now. In previous video his delivery was much darker, and that's the last thing we need right now.
It would have been useful to have included some information/theories on how and why AMOC has collapsed multiple times over the last few millennia. Thanks for the video.
Vast ice discharge from the Laurentide sheet that covered half Canada 2 km thick. It gots the characteristic red mud from Hudson's Bay (the sea not the smashing fashion & jewellery store) dumped it down the Atlantic Ocean. They aren't agreed on the reason for the 23 incidences over 85,000 years of these vast ice discharges from Canada into the Arctic Ocean & Atlantic Ocean but the "binge-purge" bulimia theory where it just got too much ice on Canada and needed a purge has been largely refuted. I don't know where the science is on that, think it's till uncertain. Dane Greenland Dorthe Dahl-Jensen only said it's curious that something happened first and the other thing after rather than the switched around way "you would think" but I've forgotten all the details. The final one was famous as "Younger Dryas" from Europe plants but it was probably the same cause as the other 22 events during the 85,000 years preceding. For study search for Dansgaard-Oeschger (DO) events and Heinrich ice-discharge events and if you want easy-listening videos rather than documents there's Jerry McManus at th-cam.com/video/J-YW8Y0ooPg/w-d-xo.html and old stuff at th-cam.com/video/I9MVmRCz9-M/w-d-xo.html and th-cam.com/video/8xPAx5IJbX0/w-d-xo.html I listened to in 2013 and forgot long ago.
It doesn't fit the human induced narratives.
Mammoths farting ?
@@jcoker423 IDK! Fred and Wilma Flintstone were living pretty high on the hog 🤣🤣
Exactly my thought. If it has collapsed multiple times, is this not just a cyclical event? Is green house gas the cause or something else? When I was a kid the climate science was predicting another ice age by now.
Excellent presentation, well documented and presented in a way that is easy for the ordinary folks like me to understand. Thank you very much . Expect more such videos.
I'm amazed you managed to keep a straight face when suggesting all countries come together to Actually create a real plan of action and follow it.. I kept waiting for a "Yeah right" or something far less Kiwi oriented..
That's the main thing: we know that all the world should collaborate to slow down or reduce the climate change trends but, at the same time, we also feel that tha's an unrealistic expectation!

One reason I follow this channel is that you present this knowledge in a simple and easily understandable format for the masses. It is one thing to talk about climate change and other studies, but half the time they are presented with enough jargon that it just goes flying over everyone's heads.
Absolutely 🙏 , The narrator does a wonderful job , Keeping it simple analytical and EZ to comprehend ‼️
And fill your head with shite 😂
Right, just follow the science follow the data and don't allow the "masses" to hear or see any of it😳
On a purely intuitive understanding I believe I will experience the AMOC stop flowing.
A visitor had come to the farmhouse and he was speaking on this. I was sleeping upstairs and remember sitting up like a jack in the box hearing his declaration.
Just knew it was something that had relevance.
Yes, it will happen within the next 10-20 years or so, the Beaufort gyre is long overdue for spilling over. th-cam.com/play/PLHSoxioQtwZcqdt3LK6d66tMreI4gqIC-.html
The AMOC stopping will naturally increase the ice coverage of the poles by decreasing temps of the poles. This will increase the ice coverage of poles which will decrease global temps and increase salinity of the oceans.
I think also its a kind of circuit.
More global warming, more clouds, more rain, less sun shine...
In the past , scientific have shown co2 concentration have never been cause of warming or frozing but everytime a consequence which act like catalyst.
So we have catalyst something who ll.be arrived thousand years in the future.
High quality production and well researched! Thanks for the time you put into this. This video puts across a very complicated subject in a way that is simple to understand.
Gentle Genius- love your teaching style - positive energy sent your way from Sunny Florida 🌞
Thanks Heather. Much appreciated :-)
I built models for govt and corps for many years. even with advanced computers it is really difficult to take into account inter-actions of all the systems: eg. sea water termp, salinity, and atmospheric circulation, east/west, south/north. with the wild card of eight or nine tipping points that can pop off randomly it all gets impossible to predict with a high degree of certainty. this is why global warming pace consistently surprises scientists. that aside, all of us need to take climate action to heart. not sure how anyone can prep to survive it. but perhaps we can delay the inevitable.
I have lived in Alaska since 1977. Since 2008, we have lost much of the cold winter season. no longer did the Kenai Peninsula fall below -30 F in the winter. Average winter temps ate 24-35 degrees. Our summer temps have risen to the mid 70's from a mid 50 degree average. Worst of all, we have experienced massive dieoff of plants and animals. Most of our spruce trees have died due to the spruce beetle not being killed off in the winter months. First we lost starfish in the ocean. Then we had massive dieoff of birds and seals that fed on previous plentiful stocks of baitfish that are no longer present. In the last 5 years, our stocks of king salmon and chum salmon have crashed so bad that there are no longer catches of sport-caught salmon allowed even if all you want to do is catch and release. Commercial fishing using set nets have been closed due to possible catching a king salmon. Also crashing are the once prolific stocks of king crab and snow crab. There is a culprit here and it is the burning of fossil fuels. Burning of coal, oil and gas produces sulphuric acid. When sulphuric acid fall into the ocean, the water gets more acidic (acid rain) and that kills the base of our food chain, zooplankton. Since 1980, the presence of zooplankton in the North Pacific Ocean has decreased by 90+ percent. This also explains why the size of the king salmon that do return to spawn are less than 20lbs a piece. in 1990, the average size of kings returning to the Kenai River averaged 54-66 lbs with about 1/3 of the salmon exceeding 65 lbs with catches of 90+ pound fish occurring weekly.. Face the reality that the Pacific Ocean is dying. The Federal Court closed the last troll fishery for King Salmon in the Pacific Ocean to stop the dieoff of about 72 Orca whales that barely survive between Canada and Washington.
These facts you mention might still be caused by the natural cycle that stops the AMOC, since the AMOC has stopped many times before in the history of our planet. I do not deny that our polution has global consequences. But we have to know wheather the due stopping of the AMOC is solely caused by antropogenetic warming or that the natural cycle is the main mechanism. In the latter case there is no preventing the collaps of the AMOC and hence the next ice age.
As posted by someone else.....
The Arctic Ocean is warming up, icebergs are growing scarcer and in some places the seals are finding the water too hot according to a report to the Commerce Department yesterday from the Consulate at Bergen, Norway. Reports from fishermen, seal hunters and explorers all point to a radical change in climate conditions and hitherto unheard of temperatures in the Arctic zone. Exploration expeditions report that scarcely any ice has been met as far north as 81 degrees 29 minutes. Soundings to a depth of 3,100 meters showed the gulf stream still very warm. Great masses of ice have been replaced by moraines of earth and stones, the report continued, while at many points well known glaciers have entirely disappeared. Very few seals and no white fish are found in the eastern Arctic, while vast shoals of herring and smelts which have never before ventured so far north, are being encountered in the old seal fishing grounds. Within a few years it is predicted that due to the ice melt the sea will rise and make most coast cities uninhabitable………I forgot to mention that this report was from November 2 , 1922, as reported by the AP and published in The Washington Post 100 years ago.
The climate has been changing for 4,500,000,000 years, you cannot fathom that number and I bet the aholes destroying art can't even tell you what a billion is. BTW I am typing underwater in NYC since we have been under water for 23 years now.

As far as 4.5 billion years of climate change, that's the age of the planet. Doesn't mean it was habitable the whole time. 800 million years ago was the first multicellular life found, and even at that period I bet no human could live.

Good job explaining a complex topic. Thank you.
Thanks for reminding us.
Sadly though, we (people knowing and caring about global warming) have known about this for about 30 years. I doubt the public will ever take any interest in the issue until the stream collapses. And people playing down the problems we face are still VERY prominent in the media.
Definitely start prepping (yeah it's going to make you look nuts) but something is going to give out soon
Adapt2030. Humanity under attack
Unfortunately us humans have advanced so rapidly that we convinced ourselves that our silly imagined human world is all there is and everything outside of it is just there for our use.
Sure the weeds growing through cracks in the pavement always give me hope. While "intelligent" life may possibly be a short term self destructive phenomenon, life in all it's splendor has been through hellish periods before and is very capable of coming back from cataclysmic events.
Indeed we have known about this for the last 30 years. It's the old chestnut that won't go away. Helped of course by "The Day After Tomorrow" movie. I was in a tech support job by then, and all my fellow nerds were quizzing me on the movie, knowing my environmental background. The number of times I had to explain that, yes, what was being illustrated was absolutely possible, but no, not in the time span depicted by the movie. And further details thereafter. If I had dined out on every explanation I'd have ended up like Mr Creosote. Excellent informative video Dave, as always. I love those dropped articles. Do you do the graphics? I may have asked this one before.
@@martincrotty haven't given up hope that my quiet corner of this world will be mostly spared from cataclysm. That being said I bought a cabin in the woods and have that stocked and ready to sustain me for a year or so (without nuclear fallout so let's hope Russia simmers down 😅)

A good video. Whether one believes in this doom scenario depends upon how much faith one has in scientific institutions. My experience working on the Great Barrier Reef since 1984 has left me like Christian who has lost his faith. I therefore have no idea what to think about this AMOC collapse phenomenon despite being a physical oceanographer. The doom stories about the Great Barrier Reef started in the 1960s and have been going on ever since. There are reports every month or so about how bad the coral is . And yet the latest statistics from the Australian Institute of Marine Science reveal it has never had more coral than this year. This despite 4 "devastating" bleaching events in just the last 6 years. The latest statistics demonstrate that many science institutions got it totally wrong about the reef. The institutions have been overtaken by groupthink. I have been calling for much better quality assurance in science institutions, something that got me fired in 2018. So, brilliant video, but there is now far too much evidence that much of the peer reviewed literature is greatly flawed. Until something is done about that, I remain a scientist to the core but a lost soul about the science institutions. Peter Ridd.
ps, why not contact me about a video on the Great Barrier Reef
I recently found out about glacier girl, a ww2 plane in Greenland that was buried under 250ft of snow in just 50 years. It’s hard to reconcile this with record melting that we hear about constantly.

And increased snowfall isn't necessarily counter-indicative of rising temperatures. In fact, increased moisture in cold climes could be indicative of warming.
Agreed. These models are speculative at best and passed off as if they are fact. We don't have the understanding or model resolution and processing power to drive it to get to the accuracy needed for the claims made. Sure it is something of concern and the models might be partly correct, but we don't know.
History has shown again and again all these predictions to be wrong. The world has a large buffering capacity that addresses most of the sky is falling issues.
The issue is humans stubborn resistance to thinking beyond their own life span. Add this to little to no knowledge of the past. What we do know is basic physics of greenhouse gases. We have pretty good grasp of how much we're adding to our shared atmosphere, oceans. We also know there's no Oil Fairy refilling the holes with hydrocarbons. That the easy fossil fuel finds are nearly non existent. That these fossil fuels provide overwhelming majority of our fertilizer needs, feed stock chemicals for thousands of products. That a spike in their usage since industrial revolution has added 7 billion new humans with 80 million net new precious humans joining us annually. Business uses the idea of leading indicators and lagging indicators to guesstimate the health of their businesses. Problem with leading indicators is you generally don't recognize them until they pass by. For me this is enough to act on! Don't need 'six sigma certainty' or an impending collision with a civilization ending meteor. Thanks for video!
I can't see how you've got fired for calling for better quality assurances. At the very least you are omitting things here and biases opinion against institutions, leading the readers to agree with your statements by defamation, the readers here dont have access to either your firing case and the scientific publishing you mentioned.
That being said, pay for publishing and pay for reading scientific articles make for bad information flow. Even worse, only-positive-results publishing eschews scientific advancement, science should also note, pier-reviewed, what doesn't work, but there are no funds for that.
Worst, and related to your post, lack of revision for why certain predictions / published papers didn't pan out don't sell, thus we don't get funds for them.
Thank you. Not enough people know about the Beaufort Gyre and the Amoc.

@@robfer5370 what that the amoc shut down *this time* is due to _mans climate change_ ?

Your work is always a delight. I have to wonder if there would be seismic or volcanic response to the shutdown due to the high and low pressure systems in progress...
Not an idiotic thought but extremely unlikely. One of the tiny regions where dense water shoves south and makes half the AMOC push (a bowl 3,000 m deep north of Jan Mayan south of Svalbard-Spitzbergen in the Greenland Sea) is directly on the fracture between North American & Asiatic tectonic plates. However, the AMOC is pushed almost entirely during the winter of course because summer is too warm there to push it, so it's already stopping & starting annually and there's no relationship between earthquakes & volcanoes there and its seasons. The ocean there will rise a tiny amount if the AMOC stops because the surface water running downhill from the South Atlantic will finally get to finish running downhill. Perhaps that will make an earthquake at that fracture zone.

Civilization collapse usually happened when a society is too rigid to adapt, for instance mesopotamia wouldn't move their great capital when the region dried up of water, so eventually they became sand people and eventually died out (if I remember correctly). Now though, the hurdle to geographic shuffling to better climes is because everywhere is occupied already, most people can't afford to simply reshuffle. Personally, I had nothing to my name so moved with ease to somewhere I can live better, although it would be harder now as I've children and a home, but at least I'm living less dependent on rigid systems than the ones I used to struggle in (cities and then high cost of living areas). When the flood comes, now im part of a community that won't/can't lock me out of the arks. I wouldn't have children now if I hadn't moved far when it was a terrifying prospect full of risks, but taking the plunge seems to have paid off. Humans are adaptable, but other species are not and all need a spot in our neighborhood arks. Let's do what we can for our wild friends, whether that's leaving them space in the garden to nest, supporting conservation groups, switching to more responsible energies, etc. That awareness felt fruitless when I had nowhere to call my own, so I moved and it is better now. 🌝
You seem to have achieved my dream. I’m quickly approaching circumstances that would allow a potential relocation to somewhere else in the world to live out my life, in a manner that you describe. Would you please offer some potential destinations for me to research and consider (?) Thank you. May you and your family have a happy, healthy and peaceful new year in 2023.

Thanks for a fascinating video with a clear explanation. I had read of the collapse of the AMOC in an article published about 20 years ago. It seemed to postulate that the result of the collapse would not be a planet overheating but that the event could usher in a new mini-ice age due to the resulting shift in ocean currents. Regardless, I have felt that what we are faced with globally is (and has been) something we as humans cannot really abort or effect even if we coordinated globally to cut our greenhouse gas emissions, etc. The best we can do is prepare for what is moving upon us in the form of such things as much more radical weather (i.e. hurricanes, tornados) as well as devastating sea level increases which will leave low lying areas such as Florida and most coastlines radically changed. This type of preparation the human race could actually do with success even at this late hour. But we fritter away invaluable time conducting useless climate control gatherings of heads of state and sign useless, unenforceable treaties and, in the end , remain in as bad a position or worse. Our governments and global organizations are the perfect example of the small orchestral violins playing on the deck of the Titanic as the ship slips below the waves. The best efforts that can achieve some sort of security is what can now be done on the personal individual scale. Do not rely on your government to save the day. They are too busy performing the political calculus to really produce a safe , secure outcome for anyone other than themselves.
Well said, John.
Though you have expressed your ideas very well, it would be good to remember that Floridians (highest spot: 345 ft.) can move to Georgia (plenty of land over 1,000 ft. and highest spot: 4,500 ft.) (Might do well to stay away from Alabama, though; Edgar Cayce predicted southern Alabama would sink.)😏
Holland has some land 6 meters below sea level (That's minus 20 ft.) and yet they have been able to cope and even to drive back the sea for hundreds of years, even BEFORE they had electric pumps.
In the German language one says, "Es wird nicht so heiss gegessen als gekocht!" ("You don't EAT the soup as hot as you COOK it!" meaning: There are LOTS of theories going round (believe it or not, making us hotter AND colder) and all from good scientists, but not ONE of them knows all the details of what it's going to be like in even forty years... a few things, maybe; everything: NO WAY!

“Do not rely on your government to save the day.” This is why I do not trust Republicans on global warming. This is your mantra and you derive conclusions from it rather than from what you see. You know well that the only institution even remotely powerful enough to stop global warming is government which you are ideologically opposed to. It is in your interest therefore to deny anthropogenic global warming, so that government will not expand. I warn you that this foolish and myopic viewpoint will come to haunt the Republican Party, particularly in places like Florida.
I do not believe in anthropogenic global warming because scientists tell me to. I believe it because it aligns with the evidence that I see and logically follows from things that science taught before we realized anything about global warming. In the past, like the during the age of the dinosaurs, the earth was significantly warmer as a result of higher CO2 levels. That CO2 was sequestered into the crust and the earth cooled, so much so that our era, the Cenozoic, is far colder than that in which the dinosaurs lived. Indeed were it not for volcanism plants would eventually freeze the earth solid. We have spent one and a half centuries releasing the Carbon that warmed the earth in previous eras. Therefore, we should expect the earth’s climate to resemble that of previous eras on account of our activity. This is an entirely logical assumption and we have photographic evidence of it happening.
Of course, the story is slightly more complicated in its details, though not in it’s conclusion. Usually volcanism is slightly more effective than sequestration, for most of the past half a billion years the earth has been free of ice caps. Indeed it’s not as if volcanism has been absent from our present Cenozoic era, in fact it’s been relatively steady. Both volcanic carbon emissions and carbon sequestration by plants have both been relatively steady. So why did it change? Well there is another reason why the earth cooled that had nothing to do with the continuous sequestration of carbon. At the beginning of the Oligocene Antarctica froze solid because of the Antarctic circumpolar current, that and the formation of the isthmus of Panama are the real reason why the Cenozoic period has been so cold. Our oceans will “fight” against global warming so to speak because its circulatory system has feedback mechanisms that favor a colder climate rather than a warmer one. But those mechanisms mitigate normal fluctuations in the warmer direction, and this not a “normal” fluctuation. The fossil fuels we burn are added on top of the steady volcanic emissions, and that is happening on a scale that’s orders of magnitude faster than plants could possibly sequester it. The effect that this has is not business as usual; it is much more akin to the eruption of a large igneous province, like the flood basalts of old. Except this time there are no flood basalts, we are dumping the CO2 into the atmosphere. If we keep dumping CO2 into the atmosphere the feedback mechanisms keeping the Cenozoic “ice house” climate in place will be overwhelmed, and the climate will go back to what it was like during the age of the dinosaurs.
Bite the bullet, you need not do anything unconstitutional. Even under a strict originalist interpretation, the Tax and Spending Clause combined with the power to raise tariffs gives Congress all the power it needs to fix this problem. The longer you wait the more extremists there will be demanding more “radical” solutions.
So, the experts don't come to the same conclusions?? So much for climate experts! Let's work on things we CAN make a dent in (eliminate waste, war, etc.).
I agree , weve globally unanimously come to the same basic conclusion that something is definitely happening. 🤔 most go to the denial. . To prepare and stay aware . Gov wont tell anything till after the fact . I think Bidens trying to kill us off. Every leader follows . I despise most people so this is the god send to my boredom , we here in suck wv havent had any traumatic weather for a long time , i mean NOTHING !!

YOU DONT .😁😂there in lies the beauty of the culling . Better be clever better stay aware . This bot in our hands is another distraction .
What I've been reading about for the last 10 years or so is a collapse of the the North Atlantic gyre. This is the portion of the circulation of the Atlantic that includes the Gulf stream and the current as it goes past the British Isles and sinks down toward the bottom of the ocean along Africa. It is believed to have failed about 13,000 years ago resulting in a sudden cooling of North America and Europe. The last ice age was just beginning to let up and the gulfstream was beginning to move north as that happened. When it collapsed, there was a resurgence of the ice age that lasted about 2,000 years. There are two main theories of why this happened. One, the rapid meltdown of the glaciers may have flooded the sea with cold water and destroyed the gyre. Two, an asteroid or comet impacted the Laurentian glacier on North America which caused a huge surge of cold water into the sea.
Younger Dryas.
Thank you so much for this important information about climate change in this video. 📹
Thank you for keeping me sane! I was teaching high school environmental science a decade ago and this was exactly what I predicted based on the studies I could access (there was little to nothing in the textbooks). TBH I could see we were past the point of no return already but all progress is still progress! Anyway, climate change & all its repercussions is such a "big picture" thing its very hard for most scientists to grasp, leave alone students or the public. But you do an excellent job, thx!!
I sometimes wonder if there is a rescue in mind (not involving Mars, if we can't do it right here, there's no hope for us there) but regarding Bloom Energy. The devices are in-use by FedEx and a couple other Fortune 500. Is there a scenario where a population collapse is welcomed by the few at which point many Bloom Energy devices (the device purportedly converts as much Carbon Dioxide to Oxygen as "tens of thousands of trees", each) are finally powered and begin scrubbing.
But then I remember Growth Capitalism and sociopathic billionaires and I think; _"Ohh that's right, never mind."._

OK but the video title is godawful misinformation CRAP. The video & lead comments are fine enough. The AMOC is NOT "global ocean circulation" (the video title), not even close. Perhaps 20% of it, probably less. GLOBAL ocean circulation is driven around Antarctica NOT around Greenland. So normal for the internet, lying clickbait titles to draw attention. Junk-science drivel not the topic of the video.
One should include the effect of the Beaufort Gyre, a cold water pool west of Greenland. The periodical outflow of this rasavoir is definitely a game changer in the flow of the golf stream.
Ah but is the rasavoir a game changer for curling ? because THAT'S the ice related one.
Happy to be proved wrong but I think the system wouldn't be a simple jump in climate - it would tend to oscillate for a thousand years or so before stabilising in a new equilibrium.
If AMOC shuts down then the North Atlantic gets colder. This reduces ice melt from Greenland which tends to allow AMOC to start up again. Once started Greenland melts again which kills off AMOC once more.
I did see a graph many years ago showing this pattern at the end of the last ice-age, although I couldn't find that graph again. The change in temperate was dramatic - complete step change. After a few years there was a step change back to the original temperature for another few years, then repeat.
This oscillation in climate would effectively kill agriculture - it is very hard to grow stuff when you've no idea what climate you are in.
There are multiple studies of paleoclimate changes which were massive temp changes that occurred within a few decades or less. Some of the oscillations are very extreme and rapid according to some studies.
@@dannybrashear5857
Yes.
Oceans currents are well known phenomenon and their cycles are 60-65 years from warm to warm ( or cold to cold ).
Now they are turning to cold phase again. North Atlantic Oscillation (NAO) and Arctic Oscillation (AO) are already in cold phase .
Last time when this happened we were under ice-age threat which suddenly changed to AGW when they turn to warm phase 1978.
Now it´s time to panic coming ice-age again (AGC - maybe?).
Climate science use these normal changes as possibility to make money.
All studies (there were plenty) which proved this oscillation are hidden somewhere because they don´t support climate change (AGW) script.
Very nicely presented as usual
Thanks a lot
Thankyou❤
What I found most striking was the animation of the AMOC. It reminded me of videos of cloud circulation on Jupiter.
Convection.
Physiscs is the same in all places.
Your point about the models is the key, in my view. There are many variables and indeed many interdependent systems that make the accurate modelling of climate change extremely challenging. Ocean circulation is just one of these systems. To make matters worse, the collections of systems itself is not static. For example, consider the effect of more CO2 on vegetation. We have already seen a 15% increase in planetary "greening" owing to rising CO2 levels. We could ask, what influence does this "greening" have on ocean circulation and vice versa?
Accurate climate forcasts would surely have to include the prime heat generator.
Basically all chrophyll converts sunlight into atmospheric heat. The green you see is what isn't converted.
Thank you. Keep us abreast.
Your last words pointing exactly who is behind you.
I listened to you with open heart that you are bringing science and not psychopath agendas.
Seems to me that the least expensive thing to avoid all these problems is to just get on and apply the plans we've already come up with. Thanks to politicians, who all appear to be under the fossil fuel industry's thumb, it isn't going to happen. What a misnomer our species name is.
Just shut everything down that emits greenhouse gases. People will figure out alternatives pretty quickly if fossil fuels are cut off completely.

WOW …. THANK YOU for making this video! Ive often wondered about this and have kept telling my kids, that here in Wisconsin, it seems like the planet is slowly shifting poles or something. Only bc the winters have not been the same since 1979. Our winters are much too warm. Thank you for making this video.
Hard to tell considering the chem clouds which is government interference. Most gardeners would doubt the CO2 story, considering plants are always starving for more. Its the same in Northern California where I have lived my life. Less and less rain since the 80s. Now our weather is more akin to Southern California patterns. Something is going on for sure.
Here’s a thought for your kids. Ask them how much the sea level will rise in the next 10 years. When they say 1-2 meters , say more like 1-2 centimeters. Then point to this guy’s nice chart showing O(1)mm rise per year. Once you ground their expectations in actual science you should be able to tackle the pole shift question with ease 😂

Surprised Dave didn't mention the north Atlantic 'cold blob' which is a dramatic illustration that the AMOC slow down is well underway. Part of the North Atlantic is now cooler than at anytime since records began about 80 years ago, and that's in a warming world!
No it isn’t. There was a temporary cold Atlantic blob for a year or two, totally normal and happens frequently.
Still there in November 2022, expected to remain until the 2050’s.
There is a tiny anomaly in the western North Atlantic about 1.5c max divergence at the surface.
You didn't mention why is that : REASON IS THAT THE ARTIC IS WARMING UP MUCH FASTER THAN THE WORLD AVERAGE !
AND THAT MEANS HUGE SWEET WATER INFLOW FROM THE NORTH INTO THE ATLANTIC !
@@galoalbertosantanaruiz5737 And arctic warming is easily explained by increased weakening of the global magnetic circuit and pole shift. and the resulting influx of solar and cosmic plasma radiation and their interaction with the earth's atmospheric and solid electric circuits.

Past performance is no guarantee and all that, but humans are remarkably good at avoiding cohesion. There was a report they managed it once briefly, but were stymied - something about multiple languages. I'm glad to hear someone is studying the AMOC. While not distracting from the work on slowing general warming, might it be also good to begin preparations for the likely future state? How will we charge our iPhone batteries at least?
Your iPhone battery will be the least of your problems.
@@incognitotorpedo42 I think he knows that :)
A number of obviously previous human species have gone extinct mostly due to climate changes. And when chaos happens and no one is able to cool the spent rods we will have massive Fukushimas and that will burn off the ozone layer and a barren rock will remain like Mars.
"I'm glad to hear someone is studying the AMOC". All kinds of scientists are studying the AMOC non stop of course. There are AMOC specialists. The US Clivar videos I listen to have an AMOC series (among other topic series).

Thank you for an excellent presentation. Really good, and presented in a fair and balanced manner. But I am concerned that the general public are becoming more cynical about modelling and scientific predictions in general (hastened by the Covid fiasco). So meteorologists and oceanographers have their work cut out trying to get their message across. Keep going!

@@vaga4239 I think it's criminal.
its all bullshit.
My grade 8 environments study teacher 27 years ago said global warming will cause current changes and a current collapse would cause massive disruptions. Guess we’re still figuring this out
I was in Greenland for a year and took the opportunity to asses the glaciers where I was stationed. Someone named the three glaciers around my location as one dead and two live. So this climate change was on going in 1956 and no one paid any attention as to why. Frankly looking at the dead glacier was like going to a funeral as the feeling was sad. I could not say anything or if I did I would be thrown to the polar bears, if you could find one. It is indeed sad to seen the degrading of the climate.
Great video! How about a video about dark aerosol (mostly tire particles) effects on melting the ice in the Arctic? Thanks!
I had thought it was mostly ships' diesel. Just a general assumption though, perhaps not applicable to Arctic. Never heard about the vehicle tyre rubber particles thing before.
@@grindupBaker not diesel, high sulphur bunker C fuel
It just seems logical to me that we should learn to live in our environment without destroying it. Sustainability should always be the primary goal and focus. I am constantly amazed at how many people revel in destruction and misery.
There is more money in destruction and misery vs peace and harmony. Wars need money and politicians are invested in wars. Trump was the only President in decades that didnt start a war or continue one.

Thank you sir
Nightmare fuel. We should be prevving (preventing), not prepping.
We’re now forced to do both
"We should be prevving"
There is no WE. Prev if you wish.
@xIcyStarzz "It's literally too late. All you can do now is get ready"
The deadline passed 5 minutes ago. Or was it 40 years ago? It is difficult to keep track of all these predictions.
There is We and we should not prevent. Prevent is a mean to control. Controlling implies to alter the natural flow. Time on tine interfering with nature turns out to be a bad idea.
You got a plan to keep the ocean running?
I had read about these currents many years ago, and knowing that when it happens, Greenland eventually affects pacific ocean temperatures, it amazes me that they keep saying that they do not understand why the La Niña and El Niño events happen in the cycles that they do.

Thanks for your support. Much appreciated :-)
Thank you for your posts! Slightly disturbed that I am getting more subtle climate denial dressed as science popping up in my feeds and I've been almost tricked. Worrying that there really are no politicians with the scientific background to actually address this fundamental existential predicament. Experts are gone and financiers have taken over the controls. It's going to get very ugly.
The financiers pay the experts who give them the answers they want.
@@richardsmith579 that's nonsense. Would you accept money to destroy the planet on which you and your family live? Then why do you assume "the experts" would? The financiers have no need to pay experts, because nobody listens to the experts. They instead own the media and modulate the presentation of facts in such a way, that public remains aligned with their profit goals.
Subtle climate denial? or just real unbiased un-politicised science, the simple truth is non of them or us really know, and we humans have no control over the universe. Live well now and the future will take care of itself.
If you post something that builds a human induced Co2 climate crisis you will get a lot of well read people who understand that this is a WEF agenda. Many also understand that the climate has always changed and will continue to do so whether we have a personal carbon credit system or not. Also scientists who study solar activity had predicted the coming 2030 freeze back in 2015 however they have now been silenced. Maybe you need to do some research yourself I’d start with the WEF personal blockchain linked carbon credit system.
What do you mean "Climate denial?" No one denies climate exists and changes. Just name climate prediction climatologists have gotten correct. Islands like the Maldives were predicted to have been flooded by now, they've risen by several meters. Our planet has benafitted from more co2. Our biggest danger is pollution, plastic in the ocean. What have you got to say about climatologists adjusting some of the records to make warming appear true, or worse than it is? I can provide graphs by NOAA and the IPCC that have removed the medieval warming period and the 1030s warming.
I think he made this video before the new statics came out. this year we had record ice in both north and south pole. The ice is growing and not shrinking. The new consensus is that it will be colder in the future not warmer.
I heard the voice of God loudly proclaim to cancel the AMOC, just last week, I've been obsessed with finding information to confirm this, and explain it's effects on our earth ever since. Thanks for this info, it's the best I've found so far.
Good info well presented. Thank you.

All down to how much fresh water the Beaufort sea gyro releases when it goes into reverse last I see reported it was 60% above normal levels.
many thanks
In recent years there has been a apparent sharp increase in the rate of decline of the AMOC though it's hard to be sure as there are large year to year fluctuations. There was a large hesitation around 2009 which resulted in a 9cm sea level rise along the US East Coast albeit temporary. It reminds me of the splutters of a petrol engine that is about to run out of fuel. Stephan Rahmsdorf said him self that it may be that current models are overestimating the stability of the AMOC.
Can you say a bit more about the temporary sea level rise? I find this an odd concept outside of tidal and weather timescales
@@sammason2300 As the Gulf Stream moves north the water is deflected east by the rotation of the Earth aka the Coriolis effect. This lowers sea level along the East Coast. If the stream weakens then sea level to it's west rises.
The Thermohaline circulation might collapse, but it won't stay that way for long. The waters around the equatorial line would become excessively hot and the water around the poles would frozen, increasing salinity of the water near the poles and then moving south towards the equatorial line, thus, restarting the circulation. However, the direction of the circulation might be different.
Not for long is a very relative term. Either way it would be catastrophic in the short term and for a long time after.
@@lrvogt1257 Yup, "not long" could easily be a decade (or more) before the salinity disparity is great enough to kickstart the circulation again. Once halted, that is a lot of water to get moving again.
@pedrolopes3542 Your thermodynamics & oceanography are wildly incorrect there. It isn't esoteric like, say, quantum physics, but it does take some hours of quiet actual fact gathering & study to produce a worthwhile thought. For example, I pondered the +ve feedback aspect of the AMOC force starters from scratch & realized the +ve feedback aspect for 8 hours in June 2020 while plastic kayaking and just a month ago heard Stefan Rahmstorf (mentioned in his video) mention a talk what I had deduced in June 2020, the +ve feedback aspect which causes "tipping point " and a bi-stable state arrangement. It does need a basic science education like British 6th Form and some genuine quiet studying though, not just a quick babble from the hip like yours. It's good that you're trying to think though.
@@grindupBaker that's a lot of words to say absolutely nothing useful.
@@dalel3608 Long is a relative term. It would certainly be long enough to be catastrophic.
I was just learning about graphite blocks being used as heat storage batteries and wondered what you make of the technology? Sufficient installation of these might be a game changer for the AMOC deterioration you just had a think about. What do you think?

Thank you for this clear explanation. I look forward to your future videos. Forgive my ignorance, but Please consider explaining the effects of the huge increase of cellular transmissions since the 1980's and its possible impact on the atmosphère. Has it possibly had any impact? Also would increased volcanic activity including ash particulates increase cooling? Many thanks!
Thank you for the new video. It's a needed dose of reality, especially when the news just covers the "talking shops" or isolated parts of the picture without putting it all together.
Usually I try to avoid pessimism, but we're absolutely heading for a worst case scenario right now. We _can_ still do plenty to slow it down and mitigate things, to "muddle through" as you said in a previous video, but as a global civilization we're not yet doing enough to even get that far.
I don't want to think about what the next 80 years will be like with rising heat levels at the equator, rising seas all over the world, and the possibility of the AMOC shutting down or greatly weakening. It's hard to imagine our interconnected civilization surviving all those simultaneous blows. Nine or ten billion people on a planet with a climate growing more and more unstable...
And it's not like this is far-future sci-fi stuff. Any baby born today will see this play out in their lifetime. It might define their lives. We have to do more to stop this future from happening!
Yep
Unless you’re over 80 or 90 you will probably see it yourself.
"Absolutely heading for a worst case scenario"... Not much room for mistaken assumptions in your outlook my friend. I suggest you retain a sliver of doubt that we know all there is to know about climate modelling.
Oh, but see you are leaving out the rest of the solar system and galaxy. Did you know that the sun in traveling through the galaxy at 500,000 km per hour? That means that the sun and the planets have a bow shock as we plow through galactic material while we orbit the milky way. Did you know that that is probably affecting the sun? There might be dramatic changes happening to the sun that we can't even imagine, because we are tiny and barely know much about the earth. Did you know the sun in 99.7% of the mass of the solar system? That's why whatever the sun is doing is going to always affect all of the planets. That's why when the sun acts up because it is traveling at 500,000 km per hour THROUGH the GALAXY, and that causes bumps and jiggles and STAR CHANGES, that it might start... ya know.. heating up planets. Please, let us know how we might "do something" to change how our local host star is dragging us through the galaxy at 500,000 km per hour. Since we obviously need to be "doing more" to slow down this heat thing that obviously COMES FROM A STAR. We silly humans, we are so worried about driving our cars and having our electricity. We should obviously be more focused on control galaxies. Right. You, friend, are a poorly informed fan of human drama that can't think past your own nose. The UNIVERSE is much much much much more complicated than you human drama fans believe. It is astonishing how big your ego is, to just assume you know what it happening to the planet because a bunch of dramatic people want to control some things so make up dramatic reasons to control you.
Even this doesn't put it all together.
We're going to run out of Arctic Sea Ice around 2035 which will abruptly increase the rate of Greenland's melt (or change things far more radically).
If other predictions are a good guide then "unlikely before 2100" should be understood to mean "near-certain before 2050". (unless we actually take real action)
