@Dirty Magic11 Normal cycles that take millenia to occur, not in 50 years. Yeah the world is gonna change terribly and billions will die. That's tough alright 🙄
Even Siberia and Antarctica will thaw out if it gets hot enough. I say keep the CO2 going and ban all natural ice and turn the poles into farmland and new trade routes. 8B people is too many anyway, 1B is more than enough. Fewer humans = less CO2, so it will all work out by itself eventually.
@Dirty Magic11 Why would I believe in these utterly extreme scenarios? Climate change will make areas that are currently full of people almost unlivable. Leading to huge social upheaval and minimum millions of deaths. I'm sad to see that outcome doesn't cause you a second thought

Its because the people against this, the people that would lose the most money for themselves made it political. When you make something political they know you'll be on your "side" of things no matter how wrong you are. We treat politics like a sport.

I am really not sure we have the salt mining or transport capacity to pull that off we are talking about thousands of cubic kilometers here with even more water that will flow in to replace that if you are even partially successful. You would probably need easily billions of tons of salt to make even a modest temporary difference. Bear in mind here that the global production of salt is only around 280 million tons annually. Also with our largest bulk carriers only having a capacity of around 400,000 tons and we only have 68 of that size transporting the billions of tons of salt into the middle of the ocean even if we had it would be an issue. In short, the ocean is simply vast and the quantities of salt that would be needed to rebalance the system are almost unfathomable certainly beyond our industrial capacity to deliver.
@@kimberlymonsini2604 Soon, maybe. A paradigm shift in information exchange is happening, to be sure. But, if the dissemination of information becomes concentrated in a proportionate few instead of homogeneously, it could be very bad, as intelligence is seperate from morality, as most people understand it. I wish they would teach the principles of Eudaimonia in school, but i had to seek out aristotle and the like on my own.
One of the things standing in the way of 'being smart' being celebrated these days is the politically inconvenient reality of biological and cultural factors influence on people's tendency to become #smart. To take the least-possible socially controversial demographic as an example: I wonder how we might better tap the impoverished population of Appalachia for hidden brilliance.
Came here for this. This movie, while not exact on the science, still brought a visual that we may need to use to get it though our collective minds that we’re destroying our planet.
When I read your comment, I thought "The Day After", which was an 80s cartoon on what happens if nuclear war ensues. Then I realized I'm just getting old.
Now I'm just imagining a sci fi book about how some intergalactic civilizations would break planetary AMOCs to cripple enemy civilizations. Awesome video!
AMOCs, Plural? Where is the next planet at? Oh, and with the hugh mass involved, I doubt can be or will be stopped suddenly. If it did I think a lot of big bumps and gigantic whirlpools (way bigger than refrigerators) would become very evident.
In the UK our average low to average high temperatures year round is like 2 to 23 while same latitude in Canada it's around -15 to 23. Winter is so much easier to deal with when we only get snow 0-4 days a year.
Yup, which is why we should be on the bleeding edge of combating climate change - we stand to suffer dramatically at the hands of the weather if the gulf stream is disrupted
As somebody living near the North sea, the "colder water sinks" is the reason it's a bad idea to dive say, a meter or 2 deep. You basically get hit by that colder water. Staying on the surface is hotter.
Where do you find these detailed animations of ocean currents? I'm trying to learn more about these currents and winds from a sailing perspective. Thanks!
Great video, as always. But I'm so tired, man. I'm tired because none of this will ever get fixed. We've been trying to get people to understand for nearly 3 decades now and it hasn't worked. We will never clean up our act, our atmosphere, nor our oceans.
It would help if people better understood the problem and those who are best in positions to make the biggest efforts did so, but we also need to keep in mind that the concept of "fixing" the situation isn't really an option, it never was. To the best of my understanding, what is happening is basically an acceleration of the natural order of things. The events and consequences are totally natural, it's the rate at which it is happening that is "unnatural". So even if overnight we somehow "fixed" everything we've done, it wouldn't undo the progression thus far, it would just remove our factor of the acceleration. However, that also doesn't mean that it would just revert to the past rate either, as the rate of change takes time as well. In short, while we totally need to work to stop accelerating things, we also can't expect it to not keep progressing regardless because it isn't just going to reverse to the old "normal". Change comes, accelerated or not, and those who choose to ignore it will be surprised and unprepared when it affects them. Like a thief in the night, either you are ready or you are not and then it is too late.
Also, even 30 years isn't as long as it seems, especially with trying to make change on a societal level. Though we certainly want things to progress faster (seeing results always feels good), there has been progress regardless. Raising the current and coming generations to love and care about actively doing good and actively avoiding bad will make some of the biggest changes we can do, but that takes time and a lot of dedicated honest effort. And it starts in families, not government.
The sad thing is, we (collective) don't even look after ourselves. Despite knowing how bad junk food is for our arteries, we continue to gorge ourselves on high fat/high sugar foods, clogging our circulatory system. The amount of "largeness" is continuing to increase, despite everybody knowing the negative effects. So if we can't even look after ourselves, what hope is there for the ocean? Yeah, I just depressed myself. Good job me.
And the carcinogenicity of meat, dairy and eggs. If people don't care about themselves, imagine caring about something as "abstract" as the planet SMH Go plant-based for your health and the planet!
Thing is, I would wager that we don't ALL know. Not even close. The amount of ignorance of a lot (most?) people is actually astounding. The US is the best example, but it's a global trend. People, somehow, know much less than they should about a whole array of topics.
@@tyrellarson Yeah never underestimate humanities capability of willful ignorance the ability to forget ignore and or fail to internalize information that is unpleasant i.e. doesn't conform to our internalized narratives. It seems that humans have evolved enough eusocial characteristics to reach the point where these internalized tribal narratives are more important than our own existence. Tribalism is a both a fascinating and terrifying evolutionary imperative that seems deeply wired into our brains. And we have maximized our species capacity for such toxic self destructive behavior by developing sorting algorithms allowing like minded individuals to find each other and form narrow minded tribes of willful ignorance and delusion.
Ohhh, I'm sure it'll be fine, maybe we can look into it in a few years. Now if you'll excuse me, I've got some forests to clear for that new coal fired power plant, progress waits for no man and all that.
I prefer real science movies like The Core and 2012, thanks. The overexaggerated and dramatized crap in The Day After Tomorrow just muddies up the waters like a Fox News report.
Sometimes it is. Making generalities is a good way to remember a concept without using too much energy for it. But the price is its truth. Seeing the problems we're facing today, making generalities about humans creating problems may not be a really good idea.
Yes! I was just thinking about Hot Mess. Did that one actually get cancelled, or is it just happening to not have any episodes for a long time? Anyway yeah, people who like this episode should go check it out.
no but I wish they did, it would help us be more educated about an actual crisis, it was just a chapter on info about the ocean currents and from where they flowed
@@rizzobitzThe entire planet is warming. If the AMOC stops, it stops carrying heat to Europe, Europe gets colder, but the heat doesn't go away, it just builds up faster in the areas the AMOC had been picking it up from.
Don't worry, it was fine even in the worst of the Ice Age, when it was some 5º colder but there were bisons and woolly rhinoceros so pretty much like Sweden or Poland today, I guess. We have more to fear from uncontrolled warming than from cooling.
Magnificent episode. Glad I decided to watch it. I would love if you could make a video detailing what you meant by "such complxity" that would include actual models, number of variables, computation power required and so on. Maybe even publish agenda first and take suggestions. Its high time we learned what does it mean when scientists say "its complicated".
@@pa28cfi I don't know. However. When the convection stream stops. Oxygen and salt will not be replenished. All life in our oceans will die. Also our planet is warming up. So I doubt the north pole will freeze up. At the other hand. There are theories that say global warming can cause a new ice age, so you might be right..........
Small changes make a big difference, that's why, I think,, if they made the pipeline to take water from the Great Lakes, I think Superior was proposed, to California it would be a disaster.
When seeing stuff like this it defies belief that people simply dismiss global warming as some hoax without giving any consideration to one of the many catalysts such as explained in this video.
At 10:10 he literally says it happened 12,000 years ago, but if it ever happens again it’s humans fault… I think everyone is in agreement we should do our best to better the environment, but the earth is going to experiences cycles and changes regardless of anything we do.
@@ChosenPlaysYT not that if it ever happens again it's our fault. But that there's a good chance this one time it's happening because of us. And that's bad enough and in our control enough that we should do something about it.
Yes. Fluid dynamics is fun isn't it. Cooler in eurpoe, but an average globally of warmer. Think less of slowly pushing a pool of water, more like dropping a hammer in it. Earth can deal with slow changes, not quick ones, even if they deliver the same energy overall.
"Low probability, high impact" basically means "It's is possible, however unlikely, that the entire planet will be massively affected by the change in currents"
@@markae0 I believe that we don't have that much of an impact as regular people, but if we could just stop being such idiots, we might actually save our planet by reducing the need for getting new stuff. But the era of consumerism...
Other interglacial periods have ended with the final ice sheets melting. The AMOC is the only current explanation we have for glacial cycles starting up quickly as seen in past records. Stopping this from happening will stop the current ice age we live in. Only people could mess that up so much.
Literally this week, scientists have reported early and unexpected signs of the amoc breaking down in which wouldn't have been expected to occur this century. So yay us! /s
This is such an awesome video! I didn’t know there was so much going on with other currents. I know a little about the east Australian current which is possibly getting faster and making the finish times for the Sydney to Hobart shorter and the circumpolar current around Antartica, I’ve heard that scientists thought it was super good at stopping anything from getting through but then they found a bunch of micro plastic and stuff. I’d love to see an episode on this if I wasn’t obvious enough already 😅
This was a really cool explanation of how temperature and solute gradients can have large scale effects. I was just wondering if we can negate the effect of excess freshwater dumping into this current system by dumping salt to compensate for the melting of ice caps.
I visited a city i north of Norway (Tromsö). By driving a way from the city ca 30min the temp was -20. and when entering the city it was only -2. The water current was worming up the air. So amazing.
Spent two weeks searching for information or an article like this for my assignment which is due tomorrow, finally got my hands on this. Great work!! This has even me given more enthusiasm for this field to make a difference.
That is the aforementioned most recent collapse of the AMOC known as the younger Dryas a name which again implies that it was not the first such event.
At first it got warmer, because the process was gradual (it had sharp peaks anyhow but relatively gradual), however at some point, when temperatures were almost as today, some catastrophe happened, some say that an ice dam collapsed in North America pouring massive amounts of fresh water to the Ocean all of sudden, others that it was a meteorite impact. Whatever the case Ireland went from a normal warm spring to a never ending freezing winter of a thousand years. It was so bad that some people began eating grass, almost literally... and then invented bread out of it, it's called the first Neolithic.
This is a good one. I like how everything is totally scientific except the cold blob. Hey what should we name that? How about HBCWDII2? Naw, how about cold blob and we call it a day? works for me.
One principle of current formation was not in this video… It’s ice formation. Since ice can’t have salt, for it to crystallize, it has to expulse the salt. Therefore creating an even heavier and colder water. Studies in 2004, if my memory serves me well, proved that with this process, the arctic was creating the force of 10x sverdrup and the antarctique about 40x. So the ice formation would be a main player in current formation. This is my assumption: So if there is less ice formation in the arctic, the warm waters of the pacific don’t go through the Bering strait which is helping to create the warm blob of the northern pacific that we see since 2016. That warm air and humidity has greatly warm temperatures in Alaska and Yukon and accelerated the melting of glaciers over there… It has more consequences that we never really talk but I guess it would be to long to post here.
thank u for sharing this! learning about this in my current paleogeoclimatology course and given this weeks update on the matter, its very eerie timing
I really like this video. So I agree with everything mentioned in this video. Will the effect of colder winters in Europe a permanent thing or will it be cancelled out by trapped carbon? I am looking at this climate modeler and it forecasts warmer winters by 4 degrees Celsius for Europe.
Not all climate models take all pertinent factors into account. They can only be as good as the data they are given by the people who designed them. This is likely to change in the near future with AI coming online and becoming more advanced.
this is why i love Be Smart. i've watched several videos on the AMOC and this is the only one that featured such an easy to follow, in depth explanation on what the AMOC actually is (the scientific process behind it). good science communication is invaluable.
I do have two more questions about this interesting and easy-to-follow explanation: - Does increased ocean acidity affect the thermohaline currents? - What would the disruption mean for ocean-dwelling algae? They are already under duress by the increased ocean acidity, but if this is another major stressor for them, we'd lose 70% of nature's oxygen sources, meaning we'd have to make do with the remaining 30% (that we keep cutting down at a rapid pace). Human women can no longer give birth to live babies if oxygen levels drop to 50% and lower.
