Is Earth's Largest Heat Transfer Really Shutting Down?

[@DavidLombardo]

I work in aviation. I have spoken with air traffic controllers who have, in some cases, worked at the same radar facilities, or control towers their entire career. Aircraft perform best into the wind. This is a fundamental rule of aviation. For this reason, runway changes are implemented to always be utilizing the winds to the best advantage. Crosswinds and tailwinds are not ideal, you want into the wind. The tower controllers in many cases have said, you know, back in the 80s, we used the XYZ runway configs maybe, 3 or 4 times per year. In some cases, it's like the east/west flows, where 99% of the time they're in a north flow, or similar. But they in some cases have said, well, now we run east/west flows half of the time we're operating...it's like, how can this be? Have the winds truly changed THAT much in just 20-30 years??? The answer is undoubtedly yes. When you hear anecdotes from everyday people like this, it really hits you, even more than the charts and hard science/data, IMO.

[@ckmbyrnes]

I also work in aviation, with ATC and on the airfield at several locations around the world, and I have never heard of this. Magnetic declination changes, sure, but not prevailing winds. What you are describing sounds more like changes to traffic patters due to increased traffic over the last 20-30 years. More planes mean more traffic on limited air and runway space necessitating updated or new approach and departure procedures.

Nonsense. We have known exactly what kind of actions we can take to mitigate or reverse the damage. The problem is greed. The biggest corporate contributors to this problem would rather make more money now at everyone's expense now and later. This is how all mega-wealthy people think. With more money they think the problem wont affect them or their children, and they're right that they'll be in the best position to survive but their greed makes them blind to the realization that they will still need everyone else around them to make being "rich" mean anything. We could have started making progress towards these problems decades ago, but instead they've sowed doubt, discontent, and apathy.

[@mr-boo]

@@JNArnold you're not wrong that greed is a large factor in this. But Tomtom isn't wrong in that collective stupidity plays a massive role too. The stupidity is sometimes in the individuals, for not understanding the science. But it is also in the collective, as in that we fail to transmit the knowledge that is available to the others in the system. It is further a collective stupidity because no individual can change the system on their own, with the best intentions in the world. I fully agree with both of you, really.

​@@mr-boo I wouldn't exactly call it stupidity (though I also won't fight the term). It's a psychological system to drive the masses towards the desired behaviour, regardless of what the individuals would want without this influence. It was developed during WWI, when the US wanted to enter the war but the US people didn't because they regarded it as a European affair. They called it Public Relations, and it was more effective than they could have hoped. In less than a year, people wanted to fight in the war. Post WWI, the same program was used to boost sales of private corporations, and a few decades later the NSDAP hijacked this exact system for their own political agenda - and if you can get a whole country to be on board with gassing millions of innocent people ... then what can this system not do? Today it is absolutely everywhere, every big corporation has its own PR office. The worst thing for climate change is that it's exactly the fossil fuel corporations that are some of the most influential and wealthy corporations, and they try to keep their profits up as much as possible, damn the consequences. That's why they boost so much money into climate change denying PR and have so much success with it.

I live in Greece. December and January are usually the months with our heaviest rainfall. For the last two years we've had barely any rain during these months. Two, maybe three medium to big rains and that's it. I have been forced to irrigate our freshly planted fruit trees DURING WINTER! In the early 2000's I was hitchhiking with a man who had a bunch of farmer friends in the south of France. They used to rely on spring rains to grow hay for next winter, the summer being too dry for such growing conditions. When I hitched with him he told me that all of his friends were seeing a shift in the weather patterns towards heavier winter rains and dry springs. This was one of many recent springs where they were forced to let their cattle graze the spring growth instead of baling it for winter, putting them effectively 'into the red' when it comes to feed production. They would all have to buy in hay for winter feeding.

Just wanted to give a counter point of view after talking with some climate scientists/oceanographers who study the AMOC directly (shoutout to Dr. Penny Holliday!). The Ditlevson & Ditlevson paper is really the only recent one that is predicting AMOC collapse this century (with a 95% confidence level which in of itself is suspicious given the unpredictably of chaotic systems like an AMOC collapse). The IPCC estimated it very unlikely to happen this century based on the scientific consensus (single digit percent level as Rahmstorf hoped). The disconnect comes from Ditlevson & Ditlevson using a novel (and controversial) analysis technique. North Atlantic (NA) Sea Surface Temperature (SST) has been used as a proxy for AMOC strength before and the usual protocol is to subtract the Global Mean SST to take out seasonal variability and the direct impact of global warming on SST. To account for polar amplification (more warming in the Arctic relative to the mean), the group subtracted 2 times the Global Mean SST from the NA SST instead. This has the effect of exaggerating the variability and decline of the AMOC and is what gives you the downward slope graph shown in the video. By just subtracting the 1 times the Global Mean, you don't see this decline. The paper also neglects to include any of the direct measurements of the AMOC strength that we have been taking continuously since 2004. The measurements showed a slight decline in the 2000s but the AMOC slowly grew in strength in 2010s (likely just due to natural variability). This is not to say the paper is wrong. It's a very sophisticated analysis for the most part and can still tell us some interesting things. But the science on AMOC collapse is in no way settled. We have to wait and see. This is also not to downplay the importance of an AMOC collapse. If the paper turns out to be right or if we don't bring down emissions this century, an AMOC collapse would be absolutely devastating for the exact reasons outlined in the video. All in all, an excellent video and an important discussion but take it with a grain of salt. (shamelessly replying to the top comment to increase visibility lol)

Having been a small fruit grower - blueberries, raspberries, blackberries, elderberries, highbush cranberries, gooseberries, plus a wild grove of mulberries - I have watched in 20 years a shift of a full hardiness zone in our area. The problem is that it's not a "clean" increase, we still get oddball very late freeze events in spring that two years ago caused a LOT of my fruits to have substantially decreased yields, both due to freeze damage and it being too cold for pollinators for nearly two weeks right in the early spring blooming season. Plus I've seen an increase in various insect pests, and a massive and unpredictable increase in fungal diseases. It's going to be worse with forestry and tree crops, as these changes may mean that you have a disease or pest that suddenly invades areas with mature trees, wiping them out. For example, they found out that cold winters can massively reduce emerald ash borer populations, but we've had enough warmer winters that even the Great Lakes States are getting hammered. Ash trees may become extremely rare in the United States due to this. So this is a huge problem. I cannot understand why so many farmers are voting for politicians that are blocking any steps to deal with climate change, because whether it's farmers in the Colorado River Basin (20 year mega-drought that may just be ending, though it's more likely a reprieve not a pardon) or farmers having to plant more southern varieties of blueberries that are inferior to the more northern ones in taste, but can survive extended heat waves better (look up Rabbiteye versus Northern Highbush Blueberries), farmers can see climate change in action over half a lifetimes of farming (20 years). As an example of how devastating this can be to farmers and crops, it's not just having to change Blueberry species, but you end up pulling up or losing mature bushes that could have lived 50 years and had over 20 years of optimal yields, and the new pushes can take 5 years to return to full yields. Assuming no drought, because freshly planted/younger bushes have less of a root system, and are more susceptible to water shortages. Look how devastating a workplace injury or layoff that causes a family to lose months of income can be - and then consider surviving a five year financial hit. There are dozens of other examples, and it's not just in the United States but all over the world agriculture will require massive, rapid changes to cope with this. Then when you have overpumping of aquifers, like in the Colorado River Basin, you end up with a collapse when that water becomes prohibitively expensive, if the dry period continues. Look up "food riots". Drought and famine have been events that have ended civilizations. Plus famine gives you more disease, and nations go to war to make sure "their" people don't starve. You've got all four horsemen covered...

We are going to have to get over our fixation with beef, wheat and corn and start growing crops that need less processing, less space and less intensive farming practices. Field corn is really of little use as food without turning it into cattle feed, corn meal and corn syrup. It is too low in nutrition to feed us as is. Refined white flour is labor and space intensive to produce. Cattle simply take up too much room and too many resources, as well as releasing a lot of methane.

The last time we could do this, and the whole country was sitting in front of the tv watching this event was in January 1997. So imagine, it has been 26 years ago that this thing could be organized.

[@RoosterCP]

[@VestedUTuber]

My only question about that is why is this happening when thermodynamics dictates that if anything, that blob should be warming like everything else. The cold water should be trying to spread out underneath the warm water rather than pooling up in one place. Don't get me wrong, I'm not denying that this is an effect of increasing global temperatures. I'm more just kinda confused by it, since it kinda defies physics. Ocean currents are driven by convective processes, so if you add more heat to the hot side of the system if anything it should intensify, as the heat is trying to move into the colder areas so that the system can achieve homeostasis. But this is the opposite of what we're actually seeing.

[@desertsky9886]

@@VestedUTuber….as ice from Greenland melts, the meltwater is freshwater and less dense than the sea water so it floats on top of the more dense sea water. This cold water patch is amplified over time and eventually slows the transport of warm water from the south. Eventually, this can result in an Ice Age. This is explained at 4:20.

[@VestedUTuber]

@@desertsky9886 Except that freshwater doesn't _stay_ freshwater, it eventually mixes with the seawater, and quite quickly for that matter. Plus, if it was just sea melt, the cold blob's concentrations would be at it's highest around Greenland's coastlines, particularly in areas where there are actively melting ice shelves. Instead we're seeing it primarily concentrated in the middle south of Greenland's southernmost tip, so either something's dragging all that freshwater into the blob quicker than the ice is actually melting or there are other factors involved.

Climate change will cause immigration, or climate refugees, to move from the hotter regions to the cooler regions. The real question no one can answer, how will climate change affect food production?

[@mykeh3155]

Not just hotter to cooler, also cooler to hotter. At least 500 million people will need to move due to going from mild to near freezing down to below freezing temps, and those already at below freezing will likely need to move closer to food sources as the sea ice will become even thicker which will cut off the northern territories from their current fishing and hunting regions. It's not clear in this video but the "comfortable" habitable belt will shrink by 20-40% very quickly after such an event, and it's highly likely that the belt will be split in the middle by immense heat. Food production is probably the easiest thing to guess at, most regions will need to change their crops, animals and production chains, many will no longer be viable, specifically in the centre of that previously mentioned belt, but also the northern regions. Global food production would probably be cut in half for several decades unless we do massive ecological engineering projects on scales we have never attempted before. This likely wouldn't matter too much though as people would be moving closer to food production anyways, one of the biggest issues right now is just getting the food to the people that need it, starvation could be completely eliminated if we could just manage food transportation and waste better.

Not the only issue we are dealing with. The Earth's magnetic field is exponentially weakening as time goes on. The EMF acts as a protective shield in relation to Solar and cosmic energies/events. As the EMF gets weaker and weaker, it becomes more and more probable that a strong Solar storm (very strong solar CME, or multiple moderate ones) will take out the currently fragile electrical grids. If that happens, that means a complete collapse of this civilization. Indeed, we are already seeing in this past few years, minor to moderate Solar events sparking auroras further and further south, and causing significant geomagnetic storms, when even 20 to 30 years ago, these events wouldn't have done either of these. Again, because of how fast the earth's magnetic field (EMF) is weakening. But this is not as well known or talked about because well, it is scarier and you can't blame humans for it. It is out of our control completely and utterly.

We have 50 years max but realistically its going to be more like 25 because in about 10 years time the amount of warming will have gotten so bad that runaway effect will have increased so much that about 10 or 15 years after that the earth WILL have become unlivable to the point that unless you are living underground you would not be able to survive.

[@ImproveYourMagic]

I wish Stefan Rahmstorf could know that he helped me choose where I moved to 10 years ago. True story. My wife and I were making plans to get away from the Eastern Coast to move elsewhere. We chose a spot and were preparing to put our house on the market. One night I randomly watched a Stefan Rahmstorf lecture on KZbin. He showed various temperature projections for different regions in the USA and Low and Behold we changed our mind. So we chose a different area with confidence based on his lecture and are so happy we did. No regrets. We have yet to experience anything that the rest of the country has the past couple years. Not one record breaking flood or heatwave in the past ten years, (yet). We would have chosen a terrible place if not for that guy. That area has been hit hard with record temps and a touch of drought. So if you’re planing on moving, watch Stefan Rahmstorf or any climate model projecting what 100-200 years looks like. We included our age expectancy because we were trying to limit how screwed things are we’re elderly. Best tip is to look at worse case scenarios.

[@pamelahornick8108]

Would you consider sharing what place you were going to choose and which state you chose? If not, I understand and will watch the videos. I'm going to look for the videos anyway. Thanks.

[@ImproveYourMagic]

@@pamelahornick8108 You’re right, rather not say. But I can elaborate on what we did. We always hated the deep snow and winter in New England. Occasional Hurricanes were a pain too. After Stefan’s lecture we ended moving where there is snow after all.(but less snow) Some snow is good because I won’t ever be in a dry or drought prone area. Hurricanes can travel up to 100 - 200 miles inland. We no longer live within 200 miles inland from the east coast. (No more power outages and fallen trees) Make sure the climate model lectures are presented by people who work in the field or are a professor or something. Stay away from Discovery Channel type videos. What you definitely want to find are models that forecast how certain regions in the USA will change at a 2.5-3 Celsius temperature rise. (that’s what Stefan had done) Year 2050 global average projection is a minimum of 1.8-2 Celsius, with extremes of 2.3 Celsius. (and they always under estimate. (I know, that’s insane. 27 years from now) I’m not a climatologist, but if you see an example of Arizona reaching 180 degrees in 200 years and right now you’re 40 years old, then you know by the time you’re 85 there will be heat waves in the 130’s. Keep that kind of math in mind. And keep away from Arizona. Hear a few other things we did researching online when choosing a town. 1- We wanted to be close enough to at least two cities for job opportunities. 2- We wrote down the names of those towns. We went to each Towns website, Wikipedia, and google to learn things like - annual precipitation and average inches of snowfall and rain. We also googled each towns name with Key words like Blizzard, Flood, dry season, and then looked at the dates of news articles of any major weather events to see if they were frequent or not. We actually did that! We also googled each towns crime rate, taxes, average income, political leaning. We even googled words like homicide, sucks, awesome, rated #1 in, rated best in, rated worst, rated last in, etc. We actually did that too! If you are expecting to be a internal climate refugee like I was, I hope some of this was helpful in some way. Lastly, but not related to weather. We used a vacation time and rented a hotel to do some very heavy people watching. We walked through multiple grocery stores, Walmart, target, a Mall, Home Depot, and just watched people. We skipped drive thru’s and ate inside fast food joints and watched people. We parked at a gas station and watched people coming in and out. Sounds creepy, but it was awesome advice someone gave us. We glanced at Prices in the stores at the same time as well. We learned the Vibe of the area and that gave us even more confidence in our decision.

[@mistyburge8472]

Could you please share which lecture video it actually was?

[@ImproveYourMagic]

@@mistyburge8472 I have no clue. You can probably save time by fast forwary through videos and stop any time you spot a USA map or a map of the North American Continent. It was posted before I watched it ten years ago because that’s when I saw it. He spoke English. It was a power point presentation. It was kind of long. And it had to have been in front of an American audience because he spent time focusing on USA. He would most likely change his talk today with updating models of the latest data to reflect recent changes. If I were to do it again today I would still watch several presentations not only by him but whom ever else I could find. Then get a feeling what the similarities are between the different climatologist and professors. I think it’s more important to look for areas to AVOID than to try and find some perfect spot. If I were able to tell him I based my moving on a talk he gave, maybe he’d say, “Jeez dude. That was risky because events can change things by a couple hundred miles here and there.” Just keep looking for talks that include scenarios that include regional behavioral changes of 2, 3, 4 Celsius scenarios. And look for those maps. Then cross your fingers and just hope for the best. That’s what I did.

Folks you don't control the climate. This blob is where ocean water circulation begins--up near Iceland. Polar waters are tasked with transferring cooler water to the equator while tropical waters are tasked with transferring warmer water to the poles. This is Mother Nature's balancing mechanism. Currently we have several oscillations in the ocean operating at once. Water stratifies by density with cold water being the densest. The Gulf Stream is part of the knob that transfers warm water to the poles. It begins in low lats & travels north, tweaked by the Coriolis Force to the northeast. The Gulf Stream cannot collapse because it is induced by the rotation of the planet. The planet has not stopped rotating. Surface currents get their push by the wind; contour currents control the ocean floor.

Calculations of temporal probability are really of academic interest only, knowing exactly when these changes are occurring is more than enough for us to respond appropriately. Cheers, Richard.

@@mantasalgorythm4809 There was a paper published that got poo poo by nearly all climatologists that the (not really) mini ice age that occurred in North America and Northern Europe when lots of people died of starvation through crop failures and etc., was caused by a pause or stuttering of the AMOC between the LATE 1500s and early 1800s. I think that now we can see what that scientist was saying is most likely true. The fact that the industrial age contributed a great deal of carbon to the atmosphere in a relatively short time, could account for that AMOC reaction. I imagine that civilization going from the agricultural age to the industrial age would have a significant.

[@massdysfunkton]

I would imagine a gradual slowing followed by collapse and then an eventual restart in an entirely new pattern after some years, which would be better imo than a total permanent loss, but i am not a climatologist or earth systems scientist and i havent done the modeling necessary to find that out so take that with a hefty grain of salt

[@dann5740]

Historians and geologists have found ice ages to be cyclical and have occured multiple times throughout earth's history. This was from a pbs documentary I watched a decade ago though, so not 100% but seems very plausible.

Excellent explanation! I wonder what the cascading effects of N. hemisphere cooling would be. Do we get a resurgence of sea ice and snow cover that reflects more sunlight back to space and decreases the overall warming due to greenhouse gasses? If so, how long would that effect last and would that, although terribly disruptive, buy more time to address GHG emissions? These are super-complex questions, but I would love to hear informed ideas and speculations in this area. Thanks for a great program.

[@waynetodd3620]

CO2 IS PLANT FOOD - wake up people, still spewing the climate warming crap and their biased weather models that have been wrong for years... they don't even mention the impact of the SUN, or the Beaufort Gyer which is about to collapse and effecting Labrador current which will really affect the AMOC - bundle up England ( So much for global warming !!! ) Humans are NOT the cause of world climate just look at prehuman history and climate. Just more one sided PBS crap.

[@mrwhatwhathuhlala2977]

The Arctic ocean would freeze over fast.

[@TieDyeVikki]

I wonder about this too. Also, overall rising temps surely trigger more volcanic activity, putting ash into the atmosphere which blocks sunlight, which in turn cools the planet back down. These kinds of cause and effect patterns are like the Earth's way of self-correcting and taking care of itself. So I'm not so worried about the Earth itself, but for all the species trying to live on it, especially humans. Related to your original thought, they've recently invented some kind of new super-white paint, which if painted on roofs would reflect sunlight and not only reduce A/C costs, but it supposedly would make a big difference in cooling the Earth. Years ago they were experimenting with huge white plastic ground coverings to take the place of ice and snow loss, for the same reason.

The next mini ice age is predicted to last for at least 300 years. We are still in an interglacial period.

[@mrwhatwhathuhlala2977]

@@Guitar6ty The Beaufort Gyre cycle hasn't switched in over twenty years ( normally a 5 or 6 yr cycle ) When it finally does release, all that cold fresh water will enter the northern Atlantic and shutdown the AMOC, and to add to that, both magnetic poles are moving towards the equator. Something major is about to happen.

it's already happening. today it's 24/12/2023, Alps, 600mt of altitude, 16 centigrades at night, no ski, no snow, no freeriding, it's over

[@psclly]

Gulf stream collapse should cool the alps, not warm them. Global warming is real, but your comment is a bit misplaced

[@Frosty294492]

Ask anyone who owns a heated pool how much energy it takes to keep it warm. Now imagine that on the scale of the world's oceans. For many years the oceans have been a "buffer zone" or "time delay" between what we have tossed into our atmosphere over the decades and the warming we are starting to feel today. When climates all over the world change at the same time, well: Enjoy everyday you have left.

I'm worried my home is going to be washed into the sea by rising sea water levels and repeated battering by strong hurricanes. And then I'll be homeless and the world will be facing dramatically increased food insecurity issues, there will be millions of climate refugees trying to escape to the narrowing band of livable land and the various warlords/oligarchs/"self-made-billionaires" will see that as an opportunity to get even richer at the cost of human lives. That's the part I'm most worried about, I guess. If I had to put a name to it.

The earth "just" came out of an ice age! Temperatures fluctuate. Expecting the earth to maintain the same temperature is crazy.

[@warrenpuckett4203]

There also is going to be a effect this winter. Even today there is smoke in the air from Canada. Black absorbs heat. It also radiates it. IN 31 days Anything above 45 Degrees latitude will radiate more heat than it absorbs in those huge tracks of burn areas. Those areas are down wind from The Bearing sea and the Gulf of Alaska. So might get colder than -40 in Yellow Knife this winter. Why no F or C? -40 is the same on both thermometers. If it dips into the Great Lakes. Those will freeze over. All of them? Then then the ice breaker will be working non stop next winter.

[@jenniferdaniel20]

I live in the Bay Area, in California, I have my whole life. I will say that this week alone there has been a significant change in the weather, as compared to previous years and even decades. The summers used to be dry and hot. This last week alone there has been a lot of moisture in the air and it has rained at least 3 nights, there has also been more wind. The weather is more tropical, it reminds me of the summers the East Coast would get.

[@bendover9813]

Only difference is, for some reason this entire summer, we’ve been getting EVEN MORE rain than usual on the East Coast, it was like a monsoon for a couple weeks…

[@robumf]

The weather systems hitting California is NOT unusual. Just your timescale is much shorter.. There been many remnants of hurricanes that happens. As long that Southern California coast waters stay below 72, Hurricanes is not your problem. There IS another issue. California is due for a %500 increase rainfall and snow pack.
