We've exhausted natural resources that simply will not be available again. Ever. There will never be another advanced civilization on this planet. Maybe that's for the best...
The result of climate change will destroy every living thing on earth, not just humans. This is the only place in the universe where we know life exists.
The Labrador current is the southerly flow from Greenland that carries the cold water from north to south.. Sea ice is definitely forming later, melting earlier and isn't as thick and it isn't as wide spread eastward as it use to be. The Innu in Labrador are very concerned about these changes since it directly affects how they hunt and travel across the ice. There is evidence warmer waters is the culprit in the melting ice and reduced ice coverage.
I think 2 other indicators also point to an AMOC slowdown - thw blue blob near Greenland (about the only spot where the ocean has cooled) - salinity at various depths are indicating an AMOC slowdown (Paul Beckwith has done several videos on the AMOC) I'm sure the severe coastal erosion along the usa eastern coastline might also indicate an AMOC slowdown, awa drought & wildfires in the Amazon? The challenge re scientific observation is that scientists prefer decades of scientific data to confirm a "diagnosis", but impact preparedness requires pro-activity. By the time scientists are happy to declare an AMOC slowdown, it will be too late for adaptation measures (which may require a few years to plan, develop & implement)... mitigation should be a priority irrespective.
@@aaronjennings8385 I saw a few of his videos. One he showed a chart that contradicted his narrative, so he just moved on. Another time it was 10-15* below normal for a couple week, then it was going to be 1* above normal and I said "watch the AGWs start freaking out", sure enough he comes out and blamed "climate change". He is a fraud or typical AGW.
@aaronjennings8385 Not a fan of? I've seen several doccies on the AMOC and the othee two indicators of a slowdown, combined with this inducator, surely shows the AMOC IS slowing already - the real question is how long this would take (years / decades / centuries). My other point waa that scientists need loads of data & time before they feel comfortable making a proclamation, but policy makers & decision makers also need time to plan & implement adaptation strategies - by the time scientists make a definite proclamation that the AMOC is slowing may be too late for govs to enact appropriate adaptation.measures. i think this is goes for quite a few climate related impacts. The best option would be to accelerate mitigation actions (decarbonisation & ecological restoration etc) rather than relying on adaptation as adaptation strategies could fail. Humans are taking a huge risk with our future by delaying action on both ecological restoration & climate!
The buoys placed outside the UK coastline where the Gulfstream passes have the last 5 years recorded a "superheating of the stream´s temperature with 3-5 C degrees while also recording a slowing down of 15%. At the tip of Greenland pointing towards the Equator there is a great underwater canyon that functions as the conveyor belt turning point and it shows signs of being filled to the brink so that the warm salt water/cold fresh water pump conversion might be in jeopardy. 50 years ago there were around 9 months of thick coastal ice all around Greenland now that´s down to barely 3 months and many places the ice so unstable that it´s not safe to travel the ice or hunt on it. Should the Gulstream come to a stop it will affect climate severely in a matter of days. It could bring significantly colder temperatures to Northern/Western Europe while USA could see Sahara like conditions possibly combined with mega hurricanes. The three large nations with highest carbon emissions per capita are, worst first, Australia, USA, Canada. ALL three named nations have OPTIMAL conditions for the cheapest energy production, offshore mega windmill parks and thus also for green hydrogen production. We should have an atmospheric carbon content of 220 PPM and now have passed insane 420 PPM. Climate tipping point after climate tipping point are triggering these very years, like the increasingly thawing Canadian/Siberian tundras that emits CO2 and the even worse greenhouse gas, methane. Politicians in the 3 nations all have in common that they do not live up to their commitments in the Paris climate accord and have not presented credible plans to do so to date. Instead they use large amounts of taxpayer money on subsidising fossil fuels in 2024! The worlds largest ongoing transition project were signed in Jan 2023 and will transition 220 million Europeans away from fossil/nuclear fuel in just a decade by raising offshore mega windmills in the North Sea. On top the worlds largest green hydrogen production. A small one digit percentage of the hydrogen will be used to ensure emission free energy even when the wind does not blow. NOTHING but ignorant and incompetent politicians that happily take money from the fossil fuel industry stand in the way for these three nations, to make a simple scaled copy/paste of this project and make their nations emissions considerable less fast while laughing all the way to the bank. Science have told us what would happen for 70 years. Our monkey DNA really shines through. Or maybe that´s to harsh words towards the monkeys? Name me one other mammal than humans, that deliberately and knowingly, destroy the very habitat that brought them to life, allowed them to thrive and multiply?

I don't know. 20 years ago I tried to tell people to stop cutting down trees and buying SUVs but they didn't listen. There is a collective mental illness people have where they don't believe the future will come so they wish to make it as bad as possible. Do they think they will really be prepared for the worst?
They're not worried about it because they think they will be gone before it's their responsibility. In other words, they don't care about their children, grandchildren, or anyone else for that matter.
With the current rapid climate disruption, everything is happening faster than expected, with the apparent signs of weakening of the Gulf Stream lending credence to further weakening of the AMOC. So many of the extreme weather events we have been seeing in the past few years would have been unheard of in the 20th century - and this is really rapid change on the historic geologic scale. No wonder climate scientists & oceanographers are having sleepless nights thinking about an AMOC shutdown.
I have mention this issue at least 15 times in my posts over the years, In addition to the AMOC (Atlantic Meridional Overturning Circulation) along with the beaufort gyre which is located just of the Greenland coast are responsible for all ocean current movement, now the beaufort gyre has been slowing down for years and is coming to the point of stopping. Now there are 4 actions that are planet will need to go through before our climate changes for the worst and a lot of experts like NASA & NOAA predict that if these 4 events happen in will put the earth into another mini ice age that could last for years. The 4 events are as follows 1. The earth's Axis Rotation, 2. The earths elliptical orbit that will put the earth farest from the sun. 3. The jet stream shutting down. 4. The collapse of the AMOC & beaufort gyre. If all 4 of these events happen within a small time frame, it will put the earth into a cold freeze like nothing anyone has ever witnessed. What do you think. ??? Thanks
Very likely as the amount of hydrocarbon burnt up fighting WW2 is astronomical then we transitioned it into a globalized industrial economy, 40 years of that is a big impulse into the system. 1.5 was probably the floor around then. Now that floor is looking more like 3 and rising fast.
Yeah seriously. Clueless people still clinging onto hope that we haven't totally destroyed our planet is pathetic. The news is 40 years behind. Go back and listen to recordings of brilliant scientists like Carl Sagan 40 years ago. It's pretty clear that we've been out of control for the entire life times of everyone alive on Earth today.
Not exactly. There is no singular tipping point and if we had have crossed the tipping point of the AMOC by 1990 I can assure you 30 years later we would be feeling it markedly where I live in the UK where our winters would be far colder as stated above. We have not had a cold winter here for over a decade. Permanent autumn these days with a few cold days in February/march. Even snow is a rarity. I used to freeze my nuts off as a kid in November, it would be frosty and icy all over the shop. These days November stays at 12 to 16oC, its nuts so I can safely say the AMOC has not yet tipped at least not to any major climate changing degree. We have however crossed planetary red lines though that is absolutely certain with the climatological red line regarding maximum emissions before warming must occur having been breached by 1998 (350ppm) after which net warming must occur according to immutable physics. I think we are at circa 430ppm presently and if you include all the other gasses we pump it actually ends up effectively near 500ppm. We crossed the ecological red line by 1990 of a maximum of 50 billion tons of materials that can be taken from this earth per year with any hope of avoiding permanent ecological damage, we are now at near twice that and perpetual growth capitalism has us on course to double it again by 2060.
population bottleneck? where? 😂 Don't get me wrong, I am all for naturally lowering the human footprint on this world but in terms of a bottleneck I see the climate taking out chunks of human population long before it hits any natural limits because despite the fact humans are terribly unwise they are very clever and can make ample drinking water from the sea and already produce 100% more grains across this earth than is needed to feed every human 2500 calories a day, we just feed half the food we grow to animals being eaten primarily by the top 20% on earth with regularity because capitalism made it more profitable to feed grains to a cow to sell as hamburger to a fat rich westerner than to ever feed a poor mother and her starving children. The only limiting factor I see on population will be the gradual collapse of the ecological and climatological systems of this world rather than any other constraints. I fully expect to see 10 to 11 billion humans here before I die. At which point I will be glad to do so.

My biggest problem with AMOC is that when we will know for sure we won't be able to do anything about it. This is people arguing for not doing more for fossil fuel transition don't understand - if even one of problems will escalate, results will be world shattering with billions dying and rest of fighting for all their lives to survive.

In Michigan the leaves haven't fallen off the trees yet. In past years by Halloween the leaves have fallen off. They haven't even changed full color yet. In the 1980's and 90's the great lakes would freeze by the middle of December and stay frozen until early April. I'm an ice fisherman and it's one of my favorite past times in the winter. The past 3 years the lakes didn't freeze until the middle of January and thawed by the end of February. We used to drive our cars on the lakes. Now we barely get enough to walk on. Need 10 inches of ice to drive on it. This climate change is happening faster then I thought it would. I thought it would take decades to see a major change. The planet is heading for a catastrophe.
first of all, the leave change because of the change in daylight hours. Second, we are in solar max. It's the most active solar cycle in decades meaning more energy is hitting earth.
@@gsmscrazycanuck9814some trees respond only to daylight hours, but plenty respond to a combination of day length and temperature. Also we are in a solar maximum, but most scientists agree that this has a minute impact on the Earths temperature, certainly not enough to explain such a huge change in the ice. Perhaps fact check yourself before commenting?
@@jacobdriscoll-clarke449 lol, are you kidding? The temperature has increased over 1* in six months. It is well published that the sun effects the global temperature.
So with the tropics heating up while also losing its monsoons, air moisture must naturally increase and this air will continue moving. Where does the rainfall go?
Ireland is further North than New York and thanks to the Gulfstream we do not the extremes in heat and cold that New York suffers from. We get mild weather and rain all year around :)
Research the Beaufort Gyre. This is what could affect the AMOC. The salinity is not like ocean water. It is nearly fresh water and thats what could/will nullify the AMOC and did anyone mention it?

The fact that there's a lot of "like minded" people who don't know junk science when they see it is actually kinda scary. And yes, this video is junk science.
@JimmyD806 Says you, pal. You have no evidence to back up your "claim". You just say it and then expect it to be true. Hate to break it to ya, but that's not how reality works.
@thereadersvoice Let me help Jimmy out. To quote the Chief Scientist Professor at the National Oceanography Centre, Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis. The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations.
@@thereadersvoice Typical comment from a leftist science denier. It's not my job to attempt to educate the ineducable, but there's ONLY one type of event in recent Earth history that can disrupt the AMOC and that's a Dryas Event or what's known as a Freshwater Discharge Event. In order for that type of event to happen, there needs to be continental glaciers covering half of North America, half of Europe, and a large part of Siberia for meltwater lakes to form on top of. It also needs to be COLD. We had 3 Dryas Events just prior to the start of our current interglacial; the Oldest Dryas, the Older Dryas, and the Younger Dryas. There were also Dryas Events observed 128,000 years ago just before the beginning of the previous interglacial. *None of the conditions exist at present for a Dryas Event.* You're probably not sharp enough to realize you're talking to someone who deals with the Earth's geology on an almost daily basis and I'm WELL-EDUCATED in the subject. Sorry, Pal, that's just the way it goes. My suggestion is take that vug that sits on your shoulders down to the local J.C. and enroll in some Earth Science courses.
The exact same thing happened at the terminus of the Eemian. It's not anthropogenic, it's a natural cycle. The only Anthro is mis-anthro as in misanthropic or misanthrope. Lol.
Yes, that is implied by the accumulation of heat in the tropics and much harsher winters in northern Europe. Local small scale currents would probably remain, though.
I wonder why the Gulf-stream would stop (even if it gets a fresh water effect from the north) not just be averted to a more southern path. And even if it would stop I wonder why that would also stop the transfer of the heat from the south to the north in the Atlantic Ocean. Would this transfer not remain just in a dfiferent, more dispersed way (not as clustered, directed, integrated as in the Gulf-stream)? Does someone have an answer or idea about these problems?
Only been tracking this for 20 years. You could also just say we really have no idea what we are looking at so take everything we say with a grain of salt. This planet has been around for lots of ice ages I'm sure this has happened many times before who ever adapts survives.
This is a scare story about things you cannot see. To quote the Chief Scientist Professor at the National Oceanography Centre, Penny Holliday, "There hasn't been a slow down.

The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really? Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.
You talk a big talk in the face of global scientific consensus. You can't just cherry-pick bits and pieces from articles, including reputable scientific journals, and expect your argument to be valid. That's not how Science works. Yes, it is true that there are variations in data and analyses, and not every study is going to come to the exact same conclusion. But, every thorough and comprehensive study, from satellite observations and surface data, conclusively shows that climate destabilization is resulting in significant warming trends and is primarily the result of a century's worth of burning fossil fuels. This is a big-picture issue, not excerpts taken from random articles, and the global scientific community has been in agreement on this for at least the past two decades.
@thereadersvoice Your argument is essentially an appeal to authority. Arguments from authority are based on the idea that a person should conform to the opinion of a perceived authority or authoritative group. Humans have been shown to feel strong emotional pressure to conform to authorities and majority positions. Is that your case? Science, however, does not work by this type of authorised consensus. Arriving at a consensus is a political or social activity that does not have to approach the truth. Einstein understood this. Interestingly, when over 100 scientists published a booklet (Hundert Autoren gegen Einstein, 1931) against him and his work on relativity, he responded "If I were wrong, it would only take one." Scientific consensus has got it very wrong on many things: how the "experts" informed us we must respond to recent pandemic is a sobering example of their hubris. I fear this conforming to the consensus is happening again in Science with the mirage of a climate crisis. To quote Bertrand Russell "Even if all the experts agree, they may well be mistaken." The video is about the shutting down of the AMOC. There is no objective scientific observational evidence for this. If you had any you would quote it to counter my argument and data.
@thereadersvoice And how am I cherry-picking? I refer to observational data covering the past 30 years and the span of both the North and South Atlantic basins. I quote reputable sources, and upto date peer reviewed literature. So how?
Newton, the genius who described the laws of physics, invented the color wheel (and the placement of the color purple), invented calculus so he could create chemistry, added up the time stamps in the Bible (what he felt was his greatest achievement), and calculated that 2060 is the end of time. The end of the planet is in the hands of humans, if humans decide not to destroy creation, it will not end. Evil wants to see creation end. Which side did you choose?
Climate is changing here in Florida especially. Winters are getting wetter and warmer. Hurricanes seem to continue cycling into the Gulf of Mexico where waters continue to be warmer. Hurricane Raphael is hitting Cuba as a Cat 3 right now it’s. November 6, 2024.
A lot of data has been mined to determine this, when they could have just looked at the temps in London over that time frame to see if they have gotten cooler. If they have, then the Gulf Stream is weakening. If they have not, then the Gulf Stream has not weakened and this is just baseless theory and conjecture.
It is so sad, when this information about the Gulf Stream has been known about since the 60-70s, and we were not able as a society to prevent this. 50+ years of the Oil Industry/Ivy League schools/Scientists/Policiticians/etc knowing, and enough action not being taken. I guess the billionaires of the world just want to live alone in domes and bunkers.
Studying, following and knowing a bunch of stuff about climate change is making it difficult to communicate with people who only recently began expressing interest in the issue.

@@thereadersvoice I agree but I also think there is an urgency that runaway global warming is imminent and the societal implications of that have no historical precedent for mankind. Analysing previous ice ages over past millenia seems to me to be a fools errand in the face of what the scientists have been telling us for decades.
4 decades? Seems like a very short amount of time to base extraordinary claims of destruction or collapse. Reminds me of 2 years ago, when claims were made that the Great Salt Lake could desiccate in 5 years, instead it grew 3.5' in 2 years. Scientists' ignored the weather and quasi-decadal pattern in the lakes fluctuation over the longer term. While modeling can be effective it also has pitfalls, misinterpretation, over simplification, assumption, data quality etc. PBS should be careful not to repeat the amplification mistake as they did on the Great Salt Lake . Keep cautionary but not exaggerated, Science still has a lot of data to gather.
I remember growing up in Florida with really hot, muggy summers, and a lot of hurricanes. There were beautiful beaches and lakes to enjoy. It’s still exactly the same now, I just remember that it used to be that way too.
During an excavation operation on May 21, 2008, a petrified log (Cretaceous Fossil) was unearthed and recognized as significant by Jeff Martin. Upon subsequent inspection of the fossil by geologists it was determined that the fossil was formerly a palm tree, approximately 72 million years old. In Nanaimo, BC, Canada. This means Vancouver Island was once tropical and had palm trees, yet the earth survived. Imagine that. Go back to your cafe latte.
Lol you know continental drift becomes a significant factor at those timescales right? Also the problem now is the rate of change, which is 20 times faster than post glacial recovery warming
Where I live in Devon in the uk we have a coastline called the Jurassic Coast. It's called that because it's full of fossils from the Jurassic period. But how did the largest cold blooded creatures ever to walk this planet survive in our cold climate? Simply, they didnt. All those millions of years ago what is now the UK was near the equator and earths climate was very different. As a point of reference if you're unsure, London is now at a similar lattitute to Quebec. Vancouver island had palm trees millions of years ago and the world still exists, yes, however that has no relationship to the subject of this video. This is about rapid climate shift that threatens our survival, not the historical climate that changed over millions of years.
Earth survived, but there were no humans then. Let us talk about how our species will survive such a fast change in climate, not only in BC, Canada, but everywhere.
Hey guys, continental drift, pole shifts, ice ages, asteroids, plagues, famine, drought, floods etc, the earth is fine. Ovean levels have risen and fallen many times. The ocean is not rising at any rate that is going to wipe out humanity. Neither will the temperature. Try to imagine how much ice has to melt. Try to imagine how much water you need to bring ocean levels up one metre. Try to imagine what it would take to heat the ocean. Look around you, there is plant life all around you. We need carbon. Plants need carbon. We are at the lowest levels of carbon in history. Plant life thrives in higher carbon content. We are at about 435 ppm now, whereas it has been as high as a few thousand ppm. Yes, humans are contributing to climate change, but how much is up for debate. It is a small amount compared to many other things, and it isn’t going to wipe out humanity. Ever.

Mass migration, resource wars, and in particular, the reduction of available drinking water and usable farmland. The fall is coming, it's just a matter of when, and how drastically.
Yes it is and will substantially cool the northern hemisphere which will lead to a serious energy security issue if we are totally reliant on renewables.
EXCELLENT PRESENTATION, AS ALWAYS... BUT I ACTUALLY JUST LOOKED AT YOUR LOVELY FACE, JUST STRAIGHT ON, AND YOU ARE STUNNING!! (I KNOW, NOT A SCIENTIFIC OBSERVATION, BUY I'M NOT A COMPUTER OR ROBOT AFTER ALL) ANYWAY, 'WEATHERED' IS ONE OF MY FAVORITE SCIENCE CHANNELS AND WILL WATCH THE NEW SHOW TOO!
Stop waggling your hands around. I can't concentrate on your words if you keep distracting my attention with constantly moving hands. This is supposed to be information delivery, not interpretive dance.
If only at the end of the last ice age those people hadn't been burning camp fires we would still be in the ice age. Because there is no way an ice can end without human caused global warming.
We still are in the ice age. We have been for 2 million years. The Mulenkovich cycles caused the last glacial maximum to end, and from then on, the earth started gradually cooling and still should be if we didn't increase co2 levels by 100ppm
I am not a climate denier, and the AMOC might indeed be slowing, but I read that the study using the undersea cables did not account for the shift in the Earth's magnetic field which has been slowly moving over the last several decades that affected their data set.
I will try to answer as best I can. First off the planetary magnetic field does not effect measurements of ocean sea currents via live buoys, Second that has absolutely no effect on recorded temperature sets from air and sea surface monitoring stations across this world, which factors in to understanding the rate of AMOC change, third the shifting magnetic field is shifting at an understandable rate between two blobs, more on that later. fourth, under sea cables are used for data transmission between nations, they have no function to scientists in terms of recording anything at all, I don't even understand why anyone would ever mention such? happy to be informed otherwise, I am by no means fully informed on these things. Fifth, and final, Scientists studying the drift of Earth’s magnetic north pole have pinpointed a change in the circulation pattern of magnetic blobs deep below Earth’s surface. They’ve learned a change in the flow underneath Canada has caused a patch of magnetic field at the edge of Earth’s core, deep within the Earth, to be stretched out. This has weakened the Canadian patch and resulted in the pole shifting towards Siberian blob over time. We have highly detailed magnetic models for the earth, anything that needed factoring in to anything else is / should be easy to do via real world measured observed data and modelling regarding such.
@@Nine-Signs Regarding your fourth point, it seems you're going against the part of the video which says data from underwater telecommunications cables was used. I'm puzzled.

The result of climate change will destroy every living thing on earth, not just humans.
This is the only place in the universe where we know life exists.
The Labrador current is the southerly flow from Greenland that carries the cold water from north to south.. Sea ice is definitely forming later, melting earlier and isn't as thick and it isn't as wide spread eastward as it use to be. The Innu in Labrador are very concerned about these changes since it directly affects how they hunt and travel across the ice. There is evidence warmer waters is the culprit in the melting ice and reduced ice coverage.
I thought the Labrador current was my dog peeing on my leg.
It's literally been warming up since last ice age.
I think 2 other indicators also point to an AMOC slowdown
- thw blue blob near Greenland (about the only spot where the ocean has cooled)
- salinity at various depths are indicating an AMOC slowdown (Paul Beckwith has done several videos on the AMOC)
I'm sure the severe coastal erosion along the usa eastern coastline might also indicate an AMOC slowdown, awa drought & wildfires in the Amazon?
The challenge re scientific observation is that scientists prefer decades of scientific data to confirm a "diagnosis", but impact preparedness requires pro-activity. By the time scientists are happy to declare an AMOC slowdown, it will be too late for adaptation measures (which may require a few years to plan, develop & implement)... mitigation should be a priority irrespective.
Right.
You lost me at Paul Beckwith. If adaptation is needed, it should be for the right reason and not some AGW scam.

He is a fraud or typical AGW.
@aaronjennings8385 Not a fan of? I've seen several doccies on the AMOC and the othee two indicators of a slowdown, combined with this inducator, surely shows the AMOC IS slowing already - the real question is how long this would take (years / decades / centuries). My other point waa that scientists need loads of data & time before they feel comfortable making a proclamation, but policy makers & decision makers also need time to plan & implement adaptation strategies - by the time scientists make a definite proclamation that the AMOC is slowing may be too late for govs to enact appropriate adaptation.measures. i think this is goes for quite a few climate related impacts. The best option would be to accelerate mitigation actions (decarbonisation & ecological restoration etc) rather than relying on adaptation as adaptation strategies could fail. Humans are taking a huge risk with our future by delaying action on both ecological restoration & climate!
Thank you PBS!
AI is here already, humanity evolution is almost complete
The buoys placed outside the UK coastline where the Gulfstream passes have the last 5 years recorded a "superheating of the stream´s temperature with 3-5 C degrees while also recording a slowing down of 15%. At the tip of Greenland pointing towards the Equator there is a great underwater canyon that functions as the conveyor belt turning point and it shows signs of being filled to the brink so that the warm salt water/cold fresh water pump conversion might be in jeopardy. 50 years ago there were around 9 months of thick coastal ice all around Greenland now that´s down to barely 3 months and many places the ice so unstable that it´s not safe to travel the ice or hunt on it. Should the Gulstream come to a stop it will affect climate severely in a matter of days. It could bring significantly colder temperatures to Northern/Western Europe while USA could see Sahara like conditions possibly combined with mega hurricanes.
The three large nations with highest carbon emissions per capita are, worst first, Australia, USA, Canada. ALL three named nations have OPTIMAL conditions for the cheapest energy production, offshore mega windmill parks and thus also for green hydrogen production. We should have an atmospheric carbon content of 220 PPM and now have passed insane 420 PPM. Climate tipping point after climate tipping point are triggering these very years, like the increasingly thawing Canadian/Siberian tundras that emits CO2 and the even worse greenhouse gas, methane. Politicians in the 3 nations all have in common that they do not live up to their commitments in the Paris climate accord and have not presented credible plans to do so to date. Instead they use large amounts of taxpayer money on subsidising fossil fuels in 2024!
The worlds largest ongoing transition project were signed in Jan 2023 and will transition 220 million Europeans away from fossil/nuclear fuel in just a decade by raising offshore mega windmills in the North Sea. On top the worlds largest green hydrogen production. A small one digit percentage of the hydrogen will be used to ensure emission free energy even when the wind does not blow. NOTHING but ignorant and incompetent politicians that happily take money from the fossil fuel industry stand in the way for these three nations, to make a simple scaled copy/paste of this project and make their nations emissions considerable less fast while laughing all the way to the bank. Science have told us what would happen for 70 years. Our monkey DNA really shines through. Or maybe that´s to harsh words towards the monkeys? Name me one other mammal than humans, that deliberately and knowingly, destroy the very habitat that brought them to life, allowed them to thrive and multiply?

@@runnergo1398 Yep, it seems that way to me too.
None of that will help increase the magnetic field strength. The sun drives climate.
With the current rapid climate disruption, everything is happening faster than expected, with the apparent signs of weakening of the Gulf Stream lending credence to further weakening of the AMOC.
So many of the extreme weather events we have been seeing in the past few years would have been unheard of in the 20th century - and this is really rapid change on the historic geologic scale. No wonder climate scientists & oceanographers are having sleepless nights thinking about an AMOC shutdown.
I have mention this issue at least 15 times in my posts over the years, In addition to the AMOC (Atlantic Meridional Overturning Circulation) along with the beaufort gyre which is located just of the Greenland coast are responsible for all ocean current movement, now the beaufort gyre has been slowing down for years and is coming to the point of stopping. Now there are 4 actions that are planet will need to go through before our climate changes for the worst and a lot of experts like NASA & NOAA predict that if these 4 events happen in will put the earth into another mini ice age that could last for years. The 4 events are as follows 1. The earth's Axis Rotation, 2. The earths elliptical orbit that will put the earth farest from the sun. 3. The jet stream shutting down. 4. The collapse of the AMOC & beaufort gyre. If all 4 of these events happen within a small time frame, it will put the earth into a cold freeze like nothing anyone has ever witnessed. What do you think. ??? Thanks
We crossed the tipping point in 1990.
Probably earlier then that
Very likely as the amount of hydrocarbon burnt up fighting WW2 is astronomical then we transitioned it into a globalized industrial economy, 40 years of that is a big impulse into the system. 1.5 was probably the floor around then. Now that floor is looking more like 3 and rising fast.
@markcalhoun8219 Oh better put your seatbelt on. Best of luck friend in your honest endeavors.
Yeah seriously. Clueless people still clinging onto hope that we haven't totally destroyed our planet is pathetic.
The news is 40 years behind. Go back and listen to recordings of brilliant scientists like Carl Sagan 40 years ago. It's pretty clear that we've been out of control for the entire life times of everyone alive on Earth today.
Not exactly. There is no singular tipping point and if we had have crossed the tipping point of the AMOC by 1990 I can assure you 30 years later we would be feeling it markedly where I live in the UK where our winters would be far colder as stated above. We have not had a cold winter here for over a decade. Permanent autumn these days with a few cold days in February/march. Even snow is a rarity. I used to freeze my nuts off as a kid in November, it would be frosty and icy all over the shop. These days November stays at 12 to 16oC, its nuts so I can safely say the AMOC has not yet tipped at least not to any major climate changing degree.
We have however crossed planetary red lines though that is absolutely certain with the climatological red line regarding maximum emissions before warming must occur having been breached by 1998 (350ppm) after which net warming must occur according to immutable physics. I think we are at circa 430ppm presently and if you include all the other gasses we pump it actually ends up effectively near 500ppm.
We crossed the ecological red line by 1990 of a maximum of 50 billion tons of materials that can be taken from this earth per year with any hope of avoiding permanent ecological damage, we are now at near twice that and perpetual growth capitalism has us on course to double it again by 2060.
Another confirmation that the ‘worst case’ emissions scenario continues to be the most accurate model. Population bottleneck, here we go.
population bottleneck? where? 😂
Don't get me wrong, I am all for naturally lowering the human footprint on this world but in terms of a bottleneck I see the climate taking out chunks of human population long before it hits any natural limits because despite the fact humans are terribly unwise they are very clever and can make ample drinking water from the sea and already produce 100% more grains across this earth than is needed to feed every human 2500 calories a day, we just feed half the food we grow to animals being eaten primarily by the top 20% on earth with regularity because capitalism made it more profitable to feed grains to a cow to sell as hamburger to a fat rich westerner than to ever feed a poor mother and her starving children.
The only limiting factor I see on population will be the gradual collapse of the ecological and climatological systems of this world rather than any other constraints. I fully expect to see 10 to 11 billion humans here before I die. At which point I will be glad to do so.

In Michigan the leaves haven't fallen off the trees yet. In past years by Halloween the leaves have fallen off. They haven't even changed full color yet. In the 1980's and 90's the great lakes would freeze by the middle of December and stay frozen until early April. I'm an ice fisherman and it's one of my favorite past times in the winter. The past 3 years the lakes didn't freeze until the middle of January and thawed by the end of February. We used to drive our cars on the lakes. Now we barely get enough to walk on. Need 10 inches of ice to drive on it. This climate change is happening faster then I thought it would. I thought it would take decades to see a major change. The planet is heading for a catastrophe.
first of all, the leave change because of the change in daylight hours. Second, we are in solar max. It's the most active solar cycle in decades meaning more energy is hitting earth.
@@gsmscrazycanuck9814some trees respond only to daylight hours, but plenty respond to a combination of day length and temperature.

To quote the Chief Scientist Professor at the National Oceanography Centre, Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC."
Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation.
Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2.
MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021)
The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv.
"Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years.
There is no climate crisis.
The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations.
@@thereadersvoice
Typical comment from a leftist science denier. It's not my job to attempt to educate the ineducable, but there's ONLY one type of event in recent Earth history that can disrupt the AMOC and that's a Dryas Event or what's known as a Freshwater Discharge Event.
In order for that type of event to happen, there needs to be continental glaciers covering half of North America, half of Europe, and a large part of Siberia for meltwater lakes to form on top of. It also needs to be COLD.
We had 3 Dryas Events just prior to the start of our current interglacial; the Oldest Dryas, the Older Dryas, and the Younger Dryas. There were also Dryas Events observed 128,000 years ago just before the beginning of the previous interglacial.
*None of the conditions exist at present for a Dryas Event.*

Wouldn’t the water is the Atlantic get stagnant because it has no circulation?
Yes, that is implied by the accumulation of heat in the tropics and much harsher winters in northern Europe. Local small scale currents would probably remain, though.
England would be like Newfoundland
I wonder why the Gulf-stream would stop (even if it gets a fresh water effect from the north) not just be averted to a more southern path. And even if it would stop I wonder why that would also stop the transfer of the heat from the south to the north in the Atlantic Ocean. Would this transfer not remain just in a dfiferent, more dispersed way (not as clustered, directed, integrated as in the Gulf-stream)? Does someone have an answer or idea about these problems?
Only been tracking this for 20 years. You could also just say we really have no idea what we are looking at so take everything we say with a grain of salt. This planet has been around for lots of ice ages I'm sure this has happened many times before who ever adapts survives.

The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really?
Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two.
The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.
You talk a big talk in the face of global scientific consensus. You can't just cherry-pick bits and pieces from articles, including reputable scientific journals, and expect your argument to be valid. That's not how Science works. Yes, it is true that there are variations in data and analyses, and not every study is going to come to the exact same conclusion. But, every thorough and comprehensive study, from satellite observations and surface data, conclusively shows that climate destabilization is resulting in significant warming trends and is primarily the result of a century's worth of burning fossil fuels. This is a big-picture issue, not excerpts taken from random articles, and the global scientific community has been in agreement on this for at least the past two decades.
@thereadersvoice
Your argument is essentially an appeal to authority. Arguments from authority are based on the idea that a person should conform to the opinion of a perceived authority or authoritative group. Humans have been shown to feel strong emotional pressure to conform to authorities and majority positions. Is that your case?
Science, however, does not work by this type of authorised consensus. Arriving at a consensus is a political or social activity that does not have to approach the truth. Einstein understood this. Interestingly, when over 100 scientists published a booklet (Hundert Autoren gegen Einstein, 1931) against him and his work on relativity, he responded "If I were wrong, it would only take one." Scientific consensus has got it very wrong on many things: how the "experts" informed us we must respond to recent pandemic is a sobering example of their hubris. I fear this conforming to the consensus is happening again in Science with the mirage of a climate crisis.
To quote Bertrand Russell "Even if all the experts agree, they may well be mistaken."
The video is about the shutting down of the AMOC. There is no objective scientific observational evidence for this. If you had any you would quote it to counter my argument and data.
@thereadersvoice And how am I cherry-picking? I refer to observational data covering the past 30 years and the span of both the North and South Atlantic basins. I quote reputable sources, and upto date peer reviewed literature. So how?
Newton, the genius who described the laws of physics, invented the color wheel (and the placement of the color purple), invented calculus so he could create chemistry, added up the time stamps in the Bible (what he felt was his greatest achievement), and calculated that 2060 is the end of time. The end of the planet is in the hands of humans, if humans decide not to destroy creation, it will not end. Evil wants to see creation end. Which side did you choose?

Just for the sake of having a planet to give to our grandkids, America MUST VOTE BLUE nov.5
Oops.
A lot of data has been mined to determine this, when they could have just looked at the temps in London over that time frame to see if they have gotten cooler. If they have, then the Gulf Stream is weakening. If they have not, then the Gulf Stream has not weakened and this is just baseless theory and conjecture.
Bots working overtime, spend more money on my research. The end is near. What about the 1200 year ebb & flow. This happens all the time.
It looks like a Van Gogh painting. Beautiful 🤩
It is so sad, when this information about the Gulf Stream has been known about since the 60-70s, and we were not able as a society to prevent this. 50+ years of the Oil Industry/Ivy League schools/Scientists/Policiticians/etc knowing, and enough action not being taken. I guess the billionaires of the world just want to live alone in domes and bunkers.
Rip florida
RIP all of us if the AMOC goes
Studying, following and knowing a bunch of stuff about climate change is making it difficult to communicate with people who only recently began expressing interest in the issue.
Sincerely me, the Commissioner.
What does this mean about how these same new people are capable of communication amongst themselves.
❤
Who's the commissioner and if the commissioner knows so much about climate, why isn't the commissioner pointing out that NONE of the conditions exist that would cause an AMOC disruption?
We will know it has turned off when it does. It will be too late. Humanity is its own worst enemy.
The sky is falling
now you understand van gogh
Yeah. Ted Danson said all life in our oceans would be gone by 1998.
Vancouver Island now has palm trees among other sw BC coastal locations in Canada. Will the palm trees push uphill or past Campbell River, BC? Weathermen cannot answer this one with ease because they do not understand flora like biologists. It is also a taboo topic in southern Ontario and Nova Scotia and most US states where palms are not grown. Remember that Canada is a political boundary and nature rules over what we think.
2:55 that's not exactly what reality looks like a bit too much starry night
So the AMOC is going amok?
(Apologies, I couldn’t help myself).
You can say that the AMOC will run amok hahaha
What do the models say about a time period of the last million years not the last few decades to get an even better understanding of how the climate evolves over longer period of time?
Is that particularly relevant in the context of a world population of 9 billion people?
@@skrich9690 To be fair, it can be helpful to get as big a picture as possible. It allows us to get accurate comparisons and gives us a better understanding of what current trends should be. Science works best when it has as much information to work with as possible.
@thereadersvoice
As much information as possible. I couldn't agree more.
So here's some more information:
To quote the Chief Scientist Professor at the National Oceanography Centre, Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC."
Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation.
Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2.
MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021)
The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv.
"Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years.
There is no climate crisis.
The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations.
@@thereadersvoice I agree but I also think there is an urgency that runaway global warming is imminent and the societal implications of that have no historical precedent for mankind. Analysing previous ice ages over past millenia seems to me to be a fools errand in the face of what the scientists have been telling us for decades.
@@thereadersvoice You don't believe what you've written.
Stop Animal Ag if we want to experience peace for all of humanity
Well.....then build a big cooling pump......duh....😅
Run on power generated from heated water.already naturally existing........ask Elon Musk😊😂🎉❤🇨🇦🙏
It's sad when I look at a place, and think it weird I don't see graffiti or trash.
Trying to find an update on last years threat . Whats happening? "Collaps as early as 2025"
Buckle up kids, you're phucked
We've seen the Day after Tomorrow
Isn't this past tense
3:07 to 3:18 ☠☠☠
4 decades? Seems like a very short amount of time to base extraordinary claims of destruction or collapse. Reminds me of 2 years ago, when claims were made that the Great Salt Lake could desiccate in 5 years, instead it grew 3.5' in 2 years. Scientists' ignored the weather and quasi-decadal pattern in the lakes fluctuation over the longer term. While modeling can be effective it also has pitfalls, misinterpretation, over simplification, assumption, data quality etc. PBS should be careful not to repeat the amplification mistake as they did on the Great Salt Lake . Keep cautionary but not exaggerated, Science still has a lot of data to gather.
Looks like Van Gogh starry night
I remember growing up in Florida with really hot, muggy summers, and a lot of hurricanes. There were beautiful beaches and lakes to enjoy. It’s still exactly the same now, I just remember that it used to be that way too.
Figure it aht, smart people!
Welcome the new ocean patterns for Hurricane Milton and Helene. Storms jump over the Pacific and into the Caribbean. Climate Change.
Meh. all is lost.
Just the EU takes measures to prevent it.
And this new administration thinks this is all a hoax.
During an excavation operation on May 21, 2008, a petrified log (Cretaceous Fossil) was unearthed and recognized as significant by Jeff Martin. Upon subsequent inspection of the fossil by geologists it was determined that the fossil was formerly a palm tree, approximately 72 million years old.
In Nanaimo, BC, Canada.
This means Vancouver Island was once tropical and had palm trees, yet the earth survived. Imagine that. Go back to your cafe latte.
Lol you know continental drift becomes a significant factor at those timescales right? Also the problem now is the rate of change, which is 20 times faster than post glacial recovery warming
Where I live in Devon in the uk we have a coastline called the Jurassic Coast. It's called that because it's full of fossils from the Jurassic period. But how did the largest cold blooded creatures ever to walk this planet survive in our cold climate? Simply, they didnt. All those millions of years ago what is now the UK was near the equator and earths climate was very different. As a point of reference if you're unsure, London is now at a similar lattitute to Quebec.
Vancouver island had palm trees millions of years ago and the world still exists, yes, however that has no relationship to the subject of this video. This is about rapid climate shift that threatens our survival, not the historical climate that changed over millions of years.
Earth survived, but there were no humans then. Let us talk about how our species will survive such a fast change in climate, not only in BC, Canada, but everywhere.
Hey guys, continental drift, pole shifts, ice ages, asteroids, plagues, famine, drought, floods etc, the earth is fine. Ovean levels have risen and fallen many times. The ocean is not rising at any rate that is going to wipe out humanity. Neither will the temperature. Try to imagine how much ice has to melt. Try to imagine how much water you need to bring ocean levels up one metre. Try to imagine what it would take to heat the ocean. Look around you, there is plant life all around you. We need carbon. Plants need carbon. We are at the lowest levels of carbon in history. Plant life thrives in higher carbon content. We are at about 435 ppm now, whereas it has been as high as a few thousand ppm. Yes, humans are contributing to climate change, but how much is up for debate. It is a small amount compared to many other things, and it isn’t going to wipe out humanity. Ever. Greed and war and disease have a better chance of that.
@@AA-vi1cc we were supposed to be under water by now, and level of change isn’t even something you can notice.
Come on with it Gulf Stream Waters. How many songs did the Hillbillies sang and write for you.
All the Reports mock America 🇺🇲 and are verbally abusive.
For America and her pain
Is humanity doomed? Maybe.
But that's not the real question. The real question is how will societal breakdown affect our ability to act ? Mass migration, resource wars, and in particular, the reduction of available drinking water and usable farmland. The fall is coming, it's just a matter of when, and how drastically.
All these ships and travels to show the problem people have been talking about for decades, this is just a travel show.
Possibly, AMOC slowing down however has been laser focused in recent years.
The sky is falling...
Ummm,,,no.
If the cure for global warming wasn't a global government, I might not be so skeptical.
Yes it is and will substantially cool the northern hemisphere which will lead to a serious energy security issue if we are totally reliant on renewables.
"and will substantially cool the northern hemisphere "
@TheDanEdwards Yep, I should have been more specific. Also modulated (in addition to greenhouse gasses) by cyclical variation in solar activity.
❤
even more stories about climate change. even after decades of chatter. yet not a single decision on what to do next. PAH !
No. Try to consider how much would be needed to change the temperature of the ocean. Try to comprehend that.
Humanity is fucked.I wont be here to see this disastrous effects but young people in really poor countries wont have much of a future.
You're right. You won't be here to see it because it won't happen until we're coming out of the next glacial period about 100,000 years from now.
Alarmist doomsday scenarios are always in the future and never happen.
😢
Wow, more wild speculation based on nothing but opinion.
WRONG WE CROSSED THE TIPPING POINT WAY BACK IN 1982 NOT 1990. WE PASSED THE POINT OF NO RETURN IN 2009 .
I would take any forecast or observation by these "scientists " with a grain of salt.
Oh Wow just like global cooling. Lame
EXCELLENT PRESENTATION, AS ALWAYS... BUT I ACTUALLY JUST LOOKED AT YOUR LOVELY FACE, JUST STRAIGHT ON, AND YOU ARE STUNNING!! (I KNOW, NOT A SCIENTIFIC OBSERVATION, BUY I'M NOT A COMPUTER OR ROBOT AFTER ALL)
ANYWAY, 'WEATHERED' IS ONE OF MY FAVORITE SCIENCE CHANNELS AND WILL WATCH THE NEW SHOW TOO!
For the fossil fuel companies, climate devastation is a cost of doing business...no biggie....
This announcer is so beautiful I could watch forever
Ph come on !
The flat Earthers say it ain't so !
Lol😂
The harsh reality is gonna really mess those folks up !
💪
There is no climate emergency. The grifters are getting quite annoying though.
Stop waggling your hands around. I can't concentrate on your words if you keep distracting my attention with constantly moving hands.
This is supposed to be information delivery, not interpretive dance.
We can’t predict a 10 day forecast i highly doubt we can predict this
I thought the govt is controlling the weather
Human farts are to blame.
If only at the end of the last ice age those people hadn't been burning camp fires we would still be in the ice age. Because there is no way an ice can end without human caused global warming.
We still are in the ice age. We have been for 2 million years. The Mulenkovich cycles caused the last glacial maximum to end, and from then on, the earth started gradually cooling and still should be if we didn't increase co2 levels by 100ppm
I am not a climate denier, and the AMOC might indeed be slowing, but I read that the study using the undersea cables did not account for the shift in the Earth's magnetic field which has been slowly moving over the last several decades that affected their data set.
I will try to answer as best I can.
First off the planetary magnetic field does not effect measurements of ocean sea currents via live buoys,
Second that has absolutely no effect on recorded temperature sets from air and sea surface monitoring stations across this world, which factors in to understanding the rate of AMOC change,
third the shifting magnetic field is shifting at an understandable rate between two blobs, more on that later.
fourth, under sea cables are used for data transmission between nations, they have no function to scientists in terms of recording anything at all, I don't even understand why anyone would ever mention such? happy to be informed otherwise, I am by no means fully informed on these things.
Fifth, and final, Scientists studying the drift of Earth’s magnetic north pole have pinpointed a change in the circulation pattern of magnetic blobs deep below Earth’s surface. They’ve learned a change in the flow underneath Canada has caused a patch of magnetic field at the edge of Earth’s core, deep within the Earth, to be stretched out. This has weakened the Canadian patch and resulted in the pole shifting towards Siberian blob over time. We have highly detailed magnetic models for the earth, anything that needed factoring in to anything else is / should be easy to do via real world measured observed data and modelling regarding such.
Bot.
@@joehopfield I don't believe myself nor the original poster are bots, I find nothing wrong with people asking questions.
"shift in the Earth's magnetic field"
@@Nine-Signs Regarding your fourth point, it seems you're going against the part of the video which says data from underwater telecommunications cables was used. I'm puzzled.
The more that melts the quicker the new ice age will begin. So many more factors to consider....magnetic poles to start with...
This I where my taxes go, making wild predictions that we can't do anything about but it gives these,scientists??, a taxpayer funded life of a lifetime holiday, then to make matters even more annoying I couldn't hear her useless drivel because of the loud background music.
