Climate Change Won't Stop The Gulf Stream. Here's Why. 

1:23 LOWER ZE GLOBE!

I understand quickly how smart you are and how dumb I am. LOL

But then the AMOC must have been constant through the history, if the earth rotation is the critical factor (?)

There's a new paper on AMOC collapse as of mid feb 2024. Will you cover it?

took your quizzie got 14/17 SO THERE

No she didn’t

yet she missed a few sets of data ... geologic records show this has happened 4 times before and marks the end of the last 4 ice ages in earths history .. making this a GEOLOGICAL NORM ... second she ignored the ice core records ... that show this has happened before this ice age started ... and history of the maya and the first nations people all have histories that have the melting of all the ice caps in our history ... making everything spewed by the media and these lying scientists FALSE ... mans contribution to global warming amounts to the same as a a person alone in a closed stadium like the astro dome and fartiing once ... THOSE ARE FACTS ... and not just cherry picked from one science discipline but derived from ALL of them ... . to prove me wrong you MUST prove the geologic record the ice core record and historical records wrong .. and since even the mayans knew about pluto before modern man found it ... that is an IMPOSSIBILITY.

Two years well spent???

Check it out, Larry: "Last week research published in the journal Nature Communications suggested that the Atlantic meridional overturning circulation (Amoc) could collapse around mid-century. Amoc is a vast movement of water around the Atlantic, driven by the downward flow of cold, salty water (which is denser than warmer, less salty water) in the far north of the ocean. It plays a major role in transferring heat from the tropics to the north, especially to northern Europe. Without it, the average temperature in this region would be between 3C and 8C cooler. The difference between the average temperature today and that of the Last Glacial Maximum 20,000 years ago (the point during the last ice age when the ice sheets were at their largest) is approximately 6C. Amoc has tipped between the “on” state and the “off” state many times in prehistory. As seawater in the northern Atlantic region warms and is diluted by meltwater running off ice and snow on land, the system reaches a critical threshold, beyond which the circulation shuts down. Scientists have been warning that, thanks to global heating, the system is weaker than it has been for 1,000 years, but a tipping was deemed unlikely this century. The new assessment suggests this might be optimistic." George Monbiot, The Guardian 2/8/23

Education has improved over the last 40 years, just as sciences and technology have improved. Teaching is a technique which can be developed and refinded, after all. If you want, check out the channel "Kurzgesagt - In a Nutshell". In my view the most efficient form of explaining compley matters in the shortest way possible. I studied Biology and I am just amazed how perfectly they are describing Biology themes in short, funny videos.

And there is a brand new lecture by Rahmstorf on the occasion of receiving the Wegener medal in April 2024. It's an excellent lecture. Same topic (AMOC) with more detailed explanation and information from a bunch of his and others' more recent studies and reviews.

Nah it's clockwise here in Australia and anti clockwise in the USA!!! Lol and that of course is the brilliance of Sabine's explanation. Because of course relativity comes into play because if I am at the Equator and the air mass is being dragged East slower than the earth is spinning then for me it feel like a West wind even though the air mass is travelling East! Interestingly winds in Equatorial zones can travel faster but because air mass is much less the force is much less than colder air in southern or northern hemispheres. Ask any old sailor. And of course the Earth isn't going to stop spinning or the sun shining! Possibly Sabine's best video.

Yeah, Sabine is the exception that proves the rule that Germans have no sense of humour. Part of her attraction is that she so brilliantly proves this with her sly one liners. Love this channel and her explanation of the Coriolis Effect was probably the most succinct that I've seen in over 50 years of looking deeply into meteorology and physics. She did it with a globe and her fingers. Brilliant.

Except she did bait you. The actual answer is yes. It’s just the wrong question. No one says it would stop the Gulf Stream and if they do they mean that it would no longer be able to warm Europe. This video is pretty much the definition of hitting the lead. Not a single reference to the AMOX u tik the very end. Given retention rates most people would have missed the bit where she says but actually yes.

The title of this video is clickbait. It suggests a scientific answer to an important question about the future climate of Europe. The answer "what you call Gulf Stream is technically the AMOC. Your question, well I don't have an answer to that ..."

In addition to the currents, the fact that the ocean is quite deep right off the coast causes the ocean and air temperatures to be more stable

New york is just slightly colder in winter than vancouver, both have light winter snowfalls in normal conditions, but Vancouver is colder than NY in summer, New York's summers are fuckin hell.

Yes and the average winter minima can easily be compared with USDA plant hardiness zone map, also used outside of US. You guys in Vancouver have palms outside, no palms in NY 😌

True. Try to concentrate in 60F, or 110F degree temperature. Which would you prefer?

Archimedes was doing maths in the rather hot climate of Sicily, Pithagoras in nearby Croton. It's not climate which determines maths, sry. Also it may get too cold for anyone to live there anyhow, that's what happened in the Younger Dryas, which is the precedent this fear builds upon.

Agree, I grew up in Australia and the existence of the trade winds played a major part in the discovery and eventual colonization of my country. Everyone just seemed to accept they exist and never bother to explain where they came from

On a tangent from that, I wonder how much effect the availability of all sorts of information and misinformation today will have on the evolution of actual science. Science is limited by the formal process in rapidity of evolution; rumors purporting to be science only take half an hour to concoct and spread. I know our host has made a conciliatory video about the teleology of Flat Earthers, but those who eschew the entire science aspect are probably beyond hope. "Climate Science" is perhaps one of the first fields to be saturated with things that are not science at all, but I was introduced to the "pseudoscience" of Continental Drift and what is now known as tectonic theory by a late 1950s science textbook in 8th grade. I agree with Galileo as quoted in Bertolt Brecht's "Life of Galileo": "Someone asked the astronomer, 'Why should we go out of our way to look for things that that an only strike a discord in the ineffable harmony? Mr. Galileo was about to demonstrate the impossible. His new stars [visible with his telescope] would have broken the outer crystal sphere, which we know of on the authority of Aristotle.' Galileo replied, 'Truth is the child of Time, not of Authority. Our ignorance is infinite, let's whittle away just one [bit]. Why should we still want to be so clever when at long last we have a chance of being a little less stupid?' "

Plumerologist my self

@@jerbiebarb perhaps you could explain?

@@alanhat5252 chatgpt says; explain how positive vorticity generates weather and sustains regional climates Positive vorticity is an important factor in generating and sustaining weather and regional climates. This is because it causes air to move in a cyclonic or counterclockwise direction in the Northern Hemisphere and clockwise in the Southern Hemisphere. This movement of air causes air masses to collide and mix, resulting in the formation of low and high pressure systems which create different weather conditions. The movement of air also helps to transport heat and moisture, allowing for clouds and precipitation to form. This circulation of air helps to regulate the temperature and humidity in a region, ultimately sustaining the regional climate. more Positive vorticity helps to transport energy from the tropics to the poles. This energy helps to drive the global climate system, which keeps regional climates in balance. Without the energy transported by positive vorticity, regional climates would be much less stable.

I wish I had known that when I lived there, would've been something I'd try to see in person. I'm also thinking that having the Gulfstream so close to shore might also contribute to the stronger currents and waves I experienced swimming at East Coast beaches. I could bob around in the same spot all day at a Gulf beach, but I always had to fight rip currents at Vero and other Atlantic side beaches. But, I should double check that my assumptions are on track. 🍀✌️😎

@@erinmac4750 The Gulf Stream comes closest to shore at Palm Beach. Northward of that, it gets farther and farther away, so it depends on where you lived. Also, although the Gulf Stream does have an effect on weather conditions that come from the east, it's not responsible for the Atlantic's rougher conditions. I think that's more because of the Atlantic's size. I grew up on the Texas Gulf Coast, so I know what you mean about how much gentler the Gulf of Mexico is.

The moisture that South Detroit got yesterday came from the Gulf of Mexico. The cold air that created the snow yesterday came from the North Pacific. The N Atlantic and N Pacific operates much the same as a old Ford model A radiator gravity cooling system. So far January came December and December so far is in January. BUT January is not over and 18 CM is coming soon. I am waiting for the next snowicane like '78 & 70CM

@@buhomorado I was in P'cola in 83 and 84. Quite nice. Last summer not so nice at the end of summer. One thing you can be sure the weather changes. Now I am in South DE-troit. Kinda warm today 1C

Indeed. There might not be any tipping point at all. As ice melts and AMOC slows, that would 'self-regulate' by not bringing as much warm water northward to cause further melting. And of course if ice caps started growing, the salt left behind from the freezing would make salinity rise in northern waters, boosting AMOC circulation. But that's just a guess from my limited understanding, obviously the system is much more complex than what a 'Saturday morning arm-chair analysis' can provide. 😉😉

@@mikefochtman7164 When the AMOC slows down, the atmosphere over the North Atlantic and Europe radiates less heat into space, which increases the temperature elsewhere including Antarctica, where the amount of melting is still conditional on our behavior (the Greenland Ice Sheet is already certain to be lost in 500 years).

Yes but the data collection is increasing rapidly.

THIS

So what do you propose? Sit on our hands and do nothing until will have a 100% accurate model? Or maybe, take the warnings of scientists and act before it's too late (if it goes that way). And if it wasn't going to go that way, we've done a good thing anyway... Yeah, the world's in a shit mess because of people like you! (People who refuse to do anything, because ' there's uncertainty'. I genuinely hate your type.)

Yeah but still she’s wrong about how the Gulf Stream is powered by only the rotation of the earth. The temperature difference between equator and poles makes up the wind speed and because of climate change the poles heat up faster than the equator and so all winds, which power the ocean currents on the surface, like the Gulf Stream. Complete clickbait as the Gulf Stream is used for the amoc too

Well the accuracy could be debated.

" Could be "..????? Yes indeed.! It absolutely could be !!

East is the direction of rotation. North and South is the axis of rotation. Even on another planet.

So you are responsible for the confusion? Communication to the public should be top priority for scientists. Instead, it's somehow just based on luck what few the the science journalist happens to understand. So please, scientists just keep in mind: journalists are idiots.

It's a German thing. Every three years the Potsdam Institute pushes this into the media and then the circus restarts. To me it's just another way of scaring people to accept being ruled by totalitarians. -Not afraid of 1 degree warmer earth? Here we have an opposite scenario to scare you with. When things get too complicated most people give up and just follow the leader, until the dust settles.

There isn't that much confusion really. The "Gulf Stream" is just a term which has slightly different meanings in different contexts. Sabine, being a physicist, should be more than familiar with the concept of scientists redefining pre-existing terms ;) Most of the time, I think of the Atlantic Gyre as a sort of highway, and the Gulf Stream as one of the roads that highway uses. The AMOC is the whole circuit/route in some contexts, but often just gets used when talking about the North Atlantic thermohaline overturning bit (the part which might get disrupted by our current climate change.) BTW: I wonder what would happen to the Gulf Stream is the middle of North America because an shallow sea again...

@@travcollier Due to techtonics, the middle of America is much higher elevation now and assuming ALL ice melted tomorrow, sea level would only rise 72 meters, which for most of the gulf and atlantic coast would mean the coastline would be70-90 miles further inland on average (with almost all of Florida being underwater). The only states that would gain coastlines would be Vermont, Arizona, Arkansas, Tennessee, and Missouri, all other currently landlocked states would still be landlocked. The topography under the water now would not change and currents require fairly deep water to maintain, and with the curve of the North American coast being mostly the same (but 70 miles further inland) the current would still end up flowing back to northern Europe.

@@DiMacky24 Yeah, I was mostly joking about that... As well as reminding folks that there are also geologic timescales. Thanks though... Your explanation is quite good. PS: I grew up in Texas and went out fossil hunting every once in a while as a kid. Now I live in Florida...

I would take issue with "world-class wineries here in Michigan". There's a reason why we talk about 'old world' and 'new world' wines. Old world wines have historically been matured naturally over time to nurture their inherent qualities, whereas new world wines are an instant artificial cocktail of laboratory-designed yeast and artificial flavour. Some US wines are very gluggable, and there are some which I would buy for a bbq or fast food based on the price. But I have NEVER found a new world wine which can compare to a well-crafted, properly matured old world wine from a good year.

@@mimikurtz2162 That's a fairly extreme generalization, especially considering that old world wines were grafted onto American rootstocks during the phyllofera epidemic of the 19th century. "well-crafted, properly matured old world wine from a good year." I'll grant you that if you represent 'old world' by the very top grapes and regions, and only from good years on top of that, you'll have a hard time finding anything that can compare, but the reality is that the best new world wines have compared favorably since the 1970s, at least in the judgment of professional tasters. Whether Michigan has world-class wineries is different question. I'll have to investigate that claim at some point.

@@haroldlanceevans Enjoy your investigations! 🍷🥴 My main point, which I may have failed to clarify, is the difference in vinification. Perhaps instead of "new world" I should have said "new world style" in which the wine is artificially flavoured and hurried by the use of designer yeasts to produce a rapid acceptable result which can be kept fairly constant across the years. Whereas an "old world style" wine matures much more slowly sparked by only a simple yeast and relying instead on the art of the winemaker to persuade the grapes to give their full potential. Thus, to a traditional European winemaker, good new world style wines will always be a good average quality even in a bad year but will never soar to the heights of some old world style wines in a good year. The best old world style wines in a particular year are not always produced by famous names. During 30 years of touring wine districts the two best white wines I ever found both came from small cooperatives, and the second best red was made by a vegetable farmer who only bottled 200 cases of three different grapes each year as a side line.

I have news for you, climate change is going to affect Michigan too. Expect crop failures, toxic algal blooms in the great lakes, wildfires and spread of diseases that are normally killed by cold winters. The quip about wine is a joke, as if to say the only thing Americans will care about is if they can't get booze. And if you think Michigan will be a climate haven, then you better get ready for the millions of refugees from southern states and countries. Michigan in the mean time gets most of its energy from coal.

Good stuff. Also, I heard somebody on the GRACE gravity team say there's a possibility of measuring changes in deep ocean currents by the change in the ocean mass. I'm not seeing how that could be much accurate though because GRACE has to measure an average 300 x 300 km square and average over 1 month in order to get accuracy with 10 mm of sea surface height. Seems way too coarse to me so I suppose the deep current change by that method would be for long time scales, many years.

@@grindupBaker I think that the changes and ocean currents when they become significant will be glaringly obvious.

Why should I believe anyone who hides behind a fake name? Are you really a Doctor? What are your bona fides? These are vital in any scientific ADULT conversation.

Great, but the deep ocean and it's salinity at a global scale is not at all well monitored and that's the problem with climate models because they don't consider the volumes/speed and heat exchange taking place down there and it's cyclic long-term impact on the surface temperature.

@@MichaelKingsfordGray we had a tobacco commercial and we showed a bunch of doctors with an alphabet behind their names testifying before Congress that tobacco was neither habit-forming not harmful. What you were talking about is a logic flaw called reference to authority.

Always keep in mind that reporters aren't trained in anything other than reporting, they know absolutely nothing about science (Graham Hancock comes to mind as he's in the news recently). They constantly get science news wrong or will report on some new study as if it is settled science, forgetting their 6th grade science lesson that one experiment is only the beginning of the scientific method, it requires the experiment to be run many, many, many.... times and get the same result every time to be science. Most become reporters because they weren't good at anything else and work in print because they aren't pretty enough to be on TV.

The persons saying like "plunge into Ice Age" are ignorant clowns or scurrilous charlatans. It averages -12 degrees here for 2 months and we don't gots no Ice Age, we have a terrific time all year here at North Lake Huron.

@@grindupBaker An ice age is more of a global phenomenon than your local air temp. The older teaching was that an ice age would come on gradually over thousands or tens of thousands of years, but other studies have suggested that temperature oscillations have shifted into noticeably colder regimes within a decade. So, you're right that "plunging" is used by alarmists to sound more extreme than the norm, however the irony is that plunging may simply be the norm.

IMO, nothing DR H. says here either allays AGW fear/concern or feeds it.., nor is meant to pointedly do so, I think.... She simply says that the possible changes to Atlantic Ocean currents are too complex, as yet, for present human comprehension or our reliable prediction-making, given our present level of science [and thus our ability to establish even-likely-probabilities about how AGW might cause unacceptably-negative consequences for some or many humans......
