13,000 Years Ago: How Bad Was the Younger Dryas in the Fertile Crescent?
Vložit

- The Pleistocene-Holocene transition is a very significant period of time, because it marks what I believe is the true foundartions for the origins of civilisation, when we see the first permanent settlements in the Fertile Crescent followed by the onset of agriculture, and from then on humanity has developed exponentially.
From an archaeological point of view, it’s truly a fascinating time period, with so many incredible sites discovered in the past century, from Ancient Jericho in the West Bank, to Mureybet and Tell Qaramel in Syria, and Kortik Tepe, Gobekli Tepe and Karahan Tepe in Turkey.
The foundations of these sites were laid either just before, during or just after the Younger Dryas cold snap, which, according to platinum spike in the Greenland Ice Core data, began around 12,822 years ago and many parts of the world returned to glacial or near-glacial conditions, a change in climate that lasted around 1,000 or so years.
Not every part of the planet was affected in the same way. In Western Europe and Greenland, the Younger Dryas is a well-defined and synchronous cold period. South America had a less well-defined initiation but a sharp termination. Australia and New Zealand were seemingly unaffected but interestingly, around 100 years or so before the onset of the Younger Dryas as recorded in the Greenland data, Antarctica showed the opposite trend and started to rapidly warm up.
With this in mind, with my personal interest in the Pre-Pottery Neolithic, I really wanted to know what was happening in the Fertile Crescent. How did the Younger Dryas affect the climate from Anatolia down to the Levant, the area which really is the true cradle of civilisation? In this video we'll find out!

Hello Matt. I have a Really Good Idea for a video or even multipile videos. But 1st, I just wanna say Ima 2year fan of your Channel and reallllyy love how youve grown Wiser and Honed your Knowledge while always keeping that Inquisitive and Curious Mind of yours. Altho I havent watched this actual video, to be honest, I dont care about the Younger Dryas. A lot of people do, and I agree that they are giving it to much attention, especially by giving it that catchy Name... But I feel like, other than the Tas Tepeler videos, you might be coming into a Blank on New Topics, hence my Idea. So, after the devastating Earthquakes that hit Eastern Turkey and Syria I wondered if the layer of soil at Gobekli Tepe, the one that was interpreted by Schmidt as evidence of Intentional Burial, could be in fact evidence of past Earthquakes? And if so, were these Earthquakes contemporaneous to Gobekli Tepes occupation? Could it have led to its demise, or partial collapse and a rebuilding cycle? I pushed to Earthquake Idea further into other sites close to the Earthquake Prone Levant and after seeing a image of the Pyramids of Gizeh, I wondered if the break in the Remnant Limestone Casing of Kafre's Pyramid could have been caused by an Earthquake rather than the supposed human dismantlement in Medieval Times? Thanks MAtt
Why don't you talk normally?
@@firstman9273 Good question.
@@firstman9273 He's got a second channel where he show he can talk normally czcams.com/video/UZk1bLDq3MM/video.html I don't understand why he is still reading like this on this channel. I think maybe he thinks it is part of his brand.
It's really good to know there's a lot of people interested in intelligent convo.
👍
Discovery channel used to be good too lol now it’s CZcams for the intelligent information now
yeah break from flat earth
And, gee this platform has really grown; very encouraging to know. Great info, investigating and commentary (photos/art)!
worst thing for the fertile crescent, would be that most of what would have been inhabited, prior, is now under hundreds of feet of ocean.
Another information packed video. Super content. Thanks Matt!
Cheers mate
Great Video ... thought going back 4000 to 5000 years ago was old times but this video goes back far further...OMG at 73 it makes me feel young
It is difficult to find the words to praise this channel sufficiently. Every new, fascinating and praiseworthy episode is quickly followed by another episode equal or better. Matt, you move from strength to strength at a dizzying pace! Near the beginning of this video I was looking at the standard climatological chart and thinking, I understand this, somewhat, from an undergraduate Earth Science course, but it may puzzle many people, and there have been major discoveries since the 1960's so it probably needs a more graphic explanation. Then, voilá, just that was provided. When I was in college, the ice cores were being planned or taken but the results had not been available. In terms of the human development, I had not heard of the Natufians or the Tepe sites.
For people of my age, or nearly so, much of this contradicts what was commonly believed in our youth. The existence of an antediluvian civilization and the Deluge itself were core beliefs that many have refused to give up because science and critical thinking are alien to many of them. The explanatory data, photographs and clear explanations provided, regularly, on this channel are absolutely essential to educate the people interested in the past in the scientific data and the possible interpretations thereof. I have learned so much from this video and previous ones. Thank you Matt, sincerely, for your great and very important educational endeavors.
Before I anoint this guy king of archelogy, I have problems with several of his points. For instance, we know for a fact, that the deepest underground tunnels and chambers that lie under the Giza plateau (flooded now) would have been flooded for the last 10,000 years. They must have dug them before the ice sheets had melted. Either that, or they quarried limestone underwater. The entire Sahara desert topography, shows evidence of the Mediterranean sea flooding it, hundreds of miles inland with waves. Explain that one, without massive tsunami waves. Catastrophic glacial lake dam failures in The mountains of Turkey, could have laid waste to Mesopotamia as well. Look at the scab land of Eastern Washington state. They are plenty of experts that want to say, that wasn't so bad either.
Caves under Giza are likely natural and if you look at the pictures of them, they do look completely natural, limestone eroded from groundwater.
The underground system at Giza has been shuttered to any real excavation, since before any of us were born. Since the Aswan dam construction, it is now impossible. It's a bigger lie, than the pounding stone theory.
It’s so much more interesting than what we’ve been led to believe but it also has very dangerous implications that are deliberately being occluded. But DAMN is it interesting!! And I hated school and learning and am now addicted to it. I’m actually spending the vast majority of my Saturday paying for a lecture by Randall Carlson in Nashville this weekend.
Youre welcome
The lot of questions that you have is the reason I'm stuck on your channel. Keep on your very good research, which makes us (your audience) better and better aware of past evolutions and transformations.
another great video matt. thanks mate.
Excellent report as always. I’m sure that we would be surprised as to the amount of preparation each one episode takes.
I gave up as I didn't have the time to make good videos, and I never even tried to convey the amount of complex information Matt manages. I've no idea how he does it
Simply fascinating & intriguing can’t have enough. Thank you for what you do.
Thanks. These have been my thoughts for a while.
A very nice addition to my liked videos. Excellent vid
I think the biggest influence of Younger Dryas temperatures is the collapse of the warm ocean current from the Gulf of Mexico to the Baltic Sea. Something triggered the collapse of the warm current, making it submerge and turn back south of Greenland. It could have been triggered by an asteroid, volcano, fresh water flood from the Lauentian ice shield, solar storm, or other. But once it started, it kept the whole Northern European area from Greenland to Siberia much colder. I expect the Gulf Stream collapse seriously dropped that region’s climate in just one season. Other regions would be affected differently.
The global temperature must reach a temperature where heat radiating into space balances solar radiation heating the earth. The law of physics dictating how much heat is radiated is Heat radiated is proportional to the surface Temperature to the 4th power. Since one part of the earth was colder, this implies that region was radiating less heat into space, and therefor other regions were warmer to increase heat radiation. (Of course, if the surface is more ice covered, then additional heat is also reflected and not absorbed, thus making ice ages cooler over all).
The climate of the Levant must also be influenced by what ever changed the Sahara from wet to desert (I.e. shifting trade wind latitude over thousands of years)
Realize that the amount of radiation that hits the earth varies over time as the orbit of earth has 3-6 cycles. Sometimes those cycles add up for an increase in radiation and sometimes a decrease. Note also that the atmosphere absorption varies as the gas mix of the atmosphere changes and as the temperature changes since there are many absorption bands in the IR and UV.
@@mrbaab5932 the milankovitch cycles are gradual changes over thousands of years. The sun also has an 11 year cycle with a slight change in radiated power maybe 1% due to more sunspots. Obviously the reflectivity of snow and ice makes a big difference. However, temperature swings that begin and end in about a life time and lasting up to 1000 years are influenced by other factors. Ice core samples indicate an ice age takes only 20 years to kick in. Ocean currents are my number one suspect. The Gulf of Mexico current does not always make it to the Baltic region. Once it collapses south of Iceland it tends to stay that way for years. I wish we had better data and better models. I suspect atmosphere has self perpetuating cycles as well. The key mechanism is very likely changing transfer of heat from warmer latitudes to higher colder latitudes. Either rain like hurricanes or ocean currents. What ever can effect those are suspect. El Nino and other cycles could combine with other factors events to create a perfect storm that flips patterns
The exact dating of the events and time span are a distraction from the best measurement or historic marker: What people were doing. I think we need to keep in mind that a number of extreme events, may not have been considered catastrophic by some witnesses days, months, or even years after any of the events. The “ripple effects” of seismic, cosmic, and solar events would have affected different regions at different times, so the cultural memory and mythology of people around the world do not attest to a single, universal, instantaneous event. Rather, consistent themes are concurrent in different regions of the world. Plus, not every significant terrestrial event contributed to the settlement and cultural development of people in the same way. We are opportunistic, and what seems counter-intuitive to us now could have made sense to us at the time. I was a Craters of the Moon National Monument last summer and was amazed at the rapidity with which native people reclaimed the vast lava fields for their use., at the same time incorporating the volcanic event into their existing culture and lore. It’s all good data, but I think sometimes we get lost in the weeds with dates and lose track of why we care: We care because we know people were going through stuff and we want to pin it all down.
excellent points
Exactly. A event in arctic Canada wouldn't necessarily effect Israel for some time. Also, this I'm not sure about, but with holes in the magnetosphere, solar flares could be isolated to regions possibly? I've heard it described in that manner. But, I don't have any knowledge of evidence for this.
Brilliant presentation. Thank you for all the effort put into this. The amount of information available today reminds of the story my Aboriginal ancestor who's story of her people walking north to Australia and South to Tasmania, told 240 years back.
Checks out, if the ocean was around 400 feet shallower, there's a ton of land in that area.
Also kinda makes sense of why India and China are so heavily populated, if a continent's worth of people suddenly needed to move there..
Wow 😳 absolutely spectacular video! I feel like I'm in college! I am going to have to watch it again and take notes! Thank you so so much for your hard work and dedication you are teaching so many people
Beautiful report mate.
Legend.
The Black Sea changed from a fresh water lake to a salt water sea approximately 7600 years ago. If you lived around the Black Sea when it was fresh water, you say there was catastrophic flood!! Thanks for the video.
I think he knows that ;-). Glad you do! Most people don't know any of this
The exchange of waters would have taken more than a few days. But it would be interesting
Very much interesting! How could it be possible such a change? The only way that I dare to think is a flood coming from the sea, i.e. a giant salt water wave. In such a case, the change would be in a matter of few hours.
It is something well worth to be investigated. Greetings, Mr. Douglas.
That ideas bean around at least 30-40 yrs. and that was one of the first consequences proposed. That local populations would have considered it a massive flood, but when you look at the area involved.
The same applies to the Mediterranean sea which appers to have ppartialy dried and flooded a number of times. Both incidents were cased by breaks in land bridges whether by water level breach or eathquakes.
Also the Caspian sea might be interesting from the point of view of salinity, as well considering salt flats and salt lakes that are present in Iran and nearby countries, most inland.
As far as surviving a cosmic impact and almost immedeately resuming village life, remember, Turkey is also famous for its underground cities, and archaeologists have been finding more and more interconnecting tunnels from Neolithic and perhaps earlier times.
Yea from around the time of the Byzantine Empire... Not from the Younger Dryas.
Great work. Thanks for this.
People likely migrated south from the North since the Younger Dryas caused Europe to be so cold. It also might not be a meteor at all. Many caves around the world at the time show "squatting man," which may not be a man at all. It looks an awful lot like what a plasma burst looks like. Maybe it was the sun scorching the earth. People ran into the caves... when it cooled off, they built settlements, likely over what was already there because that was what they knew? Just some thoughts.
I dont believe the meteor theory either! it is said that we were once more advanced in technology and I think we had Wars around the globe even the possibility that it was nuclear bombs cant be ruled out! Sounds ridiculous but I think very possible!
Very interesting, great work as usual.
You should have explained that the spieliotherm data was inverted.
The graph looked odd.
R
Yeah. That’s just one graph I used from Soreq cave. The other graphs that display the data are not too user friendly.
You do good work. I have enjoyed and have learned from your videos.
Thank you
Fascinating. It needs looked at globally. Things will not add up and be out of place. This is OK. It's all at another level when we can get the detail to a fine level encompassing so many more aspects than only a few years ago when a lot that is mainstream now was then only considered fringe. And there is so much still to decipher. Keep at it!
Great piece of work as always.Working methodically through the scientific facts.
Afternoon Matt✌🏼
Afternoon/Evening
As expected, am excellent and informative overview, and it shows the Younger Dryas was even more gradual process that I suspected.
The fact that different regions suffered different levels of environmental changes, at different rates over different times, surely must pose a question to those that believe in the global disaster model. Neither an impact nor a large solar event can explain the changes that are evident.
I look forward to part 2
Thanks mate!
One needs to remember that during the YD there were regions where the climate likely improved.
It marks the start of the Antarctica warming. The YD was the end of the cold phase.
Thanks, I don't come here to confirm what I would like to believe. I know you put a lot of effort into these and it's a valuable resource for reliable info
Excellent information as usual.
Thank you!
I found this video interesting as I'm interested in how other cultures/regions experienced the transition at the end of the iceage. A couple to remember but not mentioned in the video is that the Comet Impact Hypothesis doesnt go by Greenland ice core isotopes on their own for dating the YD. There are many other sources for this including the Black Mat Layer. Also this area wasn't covered in glaciers so they wouldn't have experienced the catastrophic floods caused by the sudden melting of the glaciers that North America and Europe did
Dating of decomposed vegetation is less accurate than the core samples, hence the large discrepancies in YDB layer dating.
These areas still possibly experienced flooding by sudden meltwater dam release from northern glaciers.
where is your evidence of catastrophic floods please
Keep it up! I'd really like to see your take when it comes to the Sumerians, where could they have come from? They have many stories and apparently there are very important projects to decode their tablets with the help of AI. From what I understand only a small fraction of the know tablets have been catalogued and translated so far. The AI is helping with translation and grouping in terms of theme and authorship. Pretty fascinating stuff going on atm. I'd love to see your perspective on it. Great video, thanks.
According to the Sumerians, the Fertile Crescent was flooded and the annunaki rebuilt their major cities.
Weird seeing the medieval
warm period and little ice age on the Greenland ice core graph as was under the impression that was just in the uk
That was a north atlantic phenomena too, like the YD
I appreciate your research and insight.
Thanks
Only 2 minutes in and you're already referencing an excellent graphic!!! Best channels ever
how do the massive timbers of redwood and sycamore trees in lebanon fit into this explanation? those species need to have water. egypt is known to import them deep into the new kingdom
Do those trees grow for 8,000 years plus? Look at the New Kingdom dates and the Yonger Dryas dates. At least 8000 years apart.
I'd be careful with taking hard dates from the flowstone data, depositional rates are not static and whilst the dry cold turns off ground water flow and warming turns deposition back on, they are good for generally separating interstadials within ice ages but they don't have fine enough dating resolution to pin down absolute dates.
I don't know much about the topic so perhaps this is stupid, but I would think that the melting of ice sheets would redistribute water-weight around the world. How would all that weight pressing down in different places on the crust affect the earth? Would it be enough to cause volcanic eruptions? If true, then we should expect a temporary 'return to cold' after every significant melting. Or maybe it is negligible?
Good point.
You also have a quickly rising water table that would intrude magma chambers creating more explosive eruptions as well. Volcanism was on overdrive during this time prior to the Younger Dryas.
Often the land under the ice rises upwards as it is no longer compressed.
This can cause large landslides and eartquakes.
It is one such landsslide that originally disconected great britain from mainland europe.
Great info!
Really appreciate you using a graph with the data, and not one of those silly ones with projection models tacked on the end, Matt. Good stuff as always! I've never really been one to buy into the catastrophism theories about the end of the Younger Dryas, but I do find it fascinating that before those few thousand years, there's extremely steady flow of ice ages and much colder temperatures, and then afterwards it's remarkably stable and quite a bit warmer. As far as I know, there isn't a reasonable explanation for this.. YET!
The Holocene is explained by Milankovitch cycles
@@gravitonthongs1363 The Holocene is our current climate epoch. Are you saying Milankovich cycle only began about 13,000 years ago? Because before the younger Dryas, there are much greater fluctuations in much colder temperatures going back hundreds of thousands of years. The Holocene stability IS the the period that stands out.
@@evbbjones7 Milankovitch cycles are measured in tens of thousand years and hundreds of thousand years. They have existed as long as the plant has existed.
@@gravitonthongs1363 Interesting. You look at temperature over a long enough period of time, and the modern era just disappears! I think you're probably right on this. The current epoch actually doesn't look too dissimilar from the climate period around 400,000 years ago during the Pleistocene. Unfortunately, you have to sift through all sorts of projection modified graphs, and it makes it fairly difficult to find the hard data.
What is peculiar though, is despite this actually looking fairly regular over a long enough period of time, our scientists feel the need to distinguish between the Pleistocene and the Holocene, and the Pleistocene went on for 2.5 million years. What's that about?
Another fascinating thing I'm noticing, is that there isn't any major deviation around 65 millions years ago at the end of the Cretaceous. If I didn't have in my head Dinosaurs were killed off by a meteor around that time, I wouldn't think there was anything notable about that spot on a chart at all. And yet we're taught 90%+ of all species died right there. Any thoughts?
@@evbbjones7 I think the requirement to distinguish the Holocene from Pleistocene is the significant reduction in biodiversity, which obviously had significant contribution from human activity.
I think maybe it was the decreased sunlight adversely affecting vegetation in a short time period that was more devastating than any temperature change. I would have presumed a larger fluctuation also.
Thank you for posting this analysis. It is very interesting that different parts of the world had varying climate during the YD.
Yeah, it’s a very important point. It was the beginning of 1000+ years of rapid warming in Antarctica for example.
I wouldn't expect anything different. Different parts of the world have different and varying climate today. It's likely they always have.
@@colinfahidi9983 It’s not about different areas having a different climate, it’s that northern regions had a much more intense cold period during the YD than the Middle East, and southern regions were actually warmer not colder. During the current warming trend, Canada’s northern area is experiencing much greater warming temperatures than the temperate areas. But I think this warming trend is worldwide.
@@SpudIs2 Did you see a warming trend in any of the graphs for the last 200 years or so? Did you see a warming trend for most of the graphs since the industrial age started?
@@mrbaab5932 Since historical records only started around 1880, the older records are all based on research and interpretation, not actual measurements. When I look at graphs from 1880 to present they show a worldwide increase of about 1°C. In Canada, where I live, the increase seems to be greater. Previous theories about the beginnings of civilization suggested that climate change was forcing the issue but in this video Matt is showing that climate change was not the driving force towards that.
It seems to me that scientists seem to neglect the fact that meteorites or comets will have landed in the oceans as well as on land. The catastrophic results on land may still have been horrific, but without some of the geological evidence you wold expect.
Excellent episode
Boom! Thank you as usual!
Thanks for watching
Great work all around. You have some interesting insights. (the "hot tub hypothesis is a potentially groundbreaking observation) And as vivid, as the image of an Ice age impact is the deeper details make it look unlikely. Yet one odd thing I have yet to have explained is the heaps of frozen mastodons in Siberia that were a major part of the ivory industry at end of the 19th century. That seems to be potential impact evidence I have not heard discussed.
There were many catastrophic floods from sudden dam release of glacier meltwater during warming periods.
Mass graves from flooding events are a common archaeological find.
@@gravitonthongs1363I think he was talking about the suddenly frozen mastodon that was found with food being chewed in it's mouth while being flash frozen.
@@Mortismors they must have been eating when the glacier water or avalanche hit.
@@gravitonthongs1363 That doesn't sound very plausible, don't think they would be eating through a tsunami impact.
@@baldr2510 we are discussing floods, not tsunami’s
Great job! One discrepancy I could see being an issue is the testing methods. Speleothems date with rings like dendrochronology, whereas ice cores I believe they are carbon dating something once living found in the core. Not only are these different testing methods but carbon dating has a few flaws. One big one is carbon-dating assumes the atmosphere was the same ratio of carbon as was in 1950. I guarantee the carbon wasn't as bad in the Younger Dryas as it was post-Industrial Revolution.
At first I thought they can calibrate that out since they know how much CO2 was in the atmosphere. But then I remembered that they ratio the amount of C14 to regular carbon, from various chemicals not just CO2. So the calculation is dependent of the amount of CO2 in the atmosphere or amount of carbon at the time in general.
@@mrbaab5932 Our starting place for Carbon dating is 1950, basically when we invented the tech to do the testing. Scientists wind back the clock to calculate how much Carbon "should" have been in the atmosphere at any given time. That data is compared against Carbon found in an object to date said object. Therefor, carbon-dating is only applicable on organics which exchanged/absorbed the carbon when alive. Rocks, glass, etc. cannot be carbon-dated.
If there was no single event that caused the onset of the YD, what process caused the platinum anomaly?
A minor impact or air burst localised to Greenland.
@@AustinKoleCarlisle the platinum anomaly is only found in Greenland
Thanks for the vid
Thanks Foghorn!
@@AncientArchitects no worries love your videos always good to listen to
Oh jolly, jolly, jolly Matt! Always information packed. Now I have the B52s song Mesopotamia on my mind!
Looking at this data, such sites as Gobekli Tepe actually make a lot more sense, in that hunter/gather clans could survive the changing conditions far better as a much broader clan with a central location. Thank you for your diligent work!
Hi Matt, I know you have that space and planets channel and wanted to see if you can do an episode on a few journal articles that have come out in past 10 year or so regarding Supernova and earth temperatures. There is a few, one of them is titled "Supernova and Nova Explosion’s Space Weather:
Correlated Megafauna Extinctions, Antarctica Ice Melts
and Biosphere Mega-disturbances"
Be cool if we could get information like this from a number of spots globally. One question, when your mention sea level, are you referencing sea level today or the sea level back then? It was a few hundred feet lower in those days.
Excellent - you had better do a follow up because now I have bunches of questions - thank you
You definitely make some valid points. I
think of areas hit by wild fires and how they
look afterwards. And they are not as hot as the heat stated in the papers. It takes the
uses of modern equipment to move the
debris left behind from the devastation of
the fire. And even with that help it takes years to reclaim the land. And they aren't
having to hunt for food or plant crops. I
tend I tend to agree
It's like 2 huge punctuation marks were instigated in a geological eye blink.
Doesn't it seem like the moment the climate settled down agriculture started?
Almost like it was waiting for the right conditions?
@@AustinKoleCarlisle The Aztec creation myth indicates that people were farming at the beginning...? Else it came about after farming became integral.
good show, Matt! different areas being affected differently by the same event only makes sense. the world is rather big, after all. however, an asteroid or comet collision drastic enough to cause the temperature plunge seen in the evidence, would have affected the whole planet, like the asteroid that ended the dinosaur era. some other, non-explosive event, (perhaps a solar flare?) could be the culprit. perhaps, just plain old vulcanism darkening the skies. more research and discoveries are needed for the whole truth to be realized.
Next? that Habu Aryar (sp) place looks like a fascinating dive, Matt! see you then!
Volcanism is so anticlimactic. People watch CZcams for entertainment, not boring old science. Where’s the fireworks and sensationalism??? 😉
It is important for a large picture view of this time period. There is tool much misinformation available right now and some people are taking advantage of the general lack of knowledge. Thanks for getting us an easy to digest data set.
Very true. Alter native history channels move into any area of little knowledge and thrive sadly. We need more channels like this taking new archeological information and making it easy to access and digest for the general public.
Any examples of this misinformation you can recall?
@@colinfahidi9983 CZcams is an entertainment platform high in popularity for creators who sell speculative fringe theory and irrational conspiracy theory as the most likely scenario.
@@gravitonthongs1363sure it can, but give examples
@@gravitonthongs1363 "Conspiracy Theory" 😂😂😂😂😂😂
Excellent. Thanks
I think there is enough evidence to show some kind of cosmic impact event. The extent of it, and its correlation to the YD is still up in the air. I am interested in the Abu Hureyra "anomaly"; geological evidence of an event, but no anthropological evidence. I compare this to the quantum mechanics vs general relativity problem in physics: we know both work, just not with each other.
I’m going to do a deep dive into Abu Hureyra. I’ve already started writing it. The meltglass and impact-related deposits don’t match up with the anthropology and archaeology in my opinion. It’s possible, yes, but just seems unlikely. I’ll go into the detail in the next video.
Blast crystal can form from volcanic eruptions.
To keep things in perspective - There is a 4-10 degree average temperature differential between northern New Brunswick and SW Ontario Canada . . . 350 miles N-S longitude difference . . . most days of the year. Means shorter summers and long winters or put another way, short vs long ski season, otherwise we wouldn't notice interprovincial cooling period we are living in today.
May be it was due to the Milankovich Cycles. I remember evidence suggestion Saudi Arabia being a wet land with thousands of lakes hippos, elephants etc. 80k years ago. And there is the talk about Sahara being a wet land similarly.
Nope, not on that time scale, too fast. The most widely accepted explanation is that it was due from a slowing or reversing of the Atlantic current, possibly triggered by glacial meltwater flooding into the north atlantic.
I would love to here you and Randall talk about your findings.
Just that graph... I mean really, with that ice core data alone - to attribute global climactic factors to humans is an astounding leap by the current 'experts'. Younger Dryas = Earth's pole shift cycle based on Solar Cycles, which are now becoming increasingly evident. The Adam and Eve story by Chan Thomas.
I'd like to see you snd Randall Carlson have a conversation snd see what type of common ground you can find or if it just doesn't mesh at all.
In North America there was a huge ice dam lake that when it turned loose it was a mega-tsunami. There may be someone that conflated that with catastrophic sea level rise of hundreds of feet over many years as a mega-tsunami, but I’ve never seen it. There are many riverbeds and ancient roads that can be seen on satellite pictures going into the ocean. You don’t get eroded riverbeds under water. There is a gravitational anomaly pointing a impactor in the northern hemisphere. There is another anomaly off the coast of India (maybe? The impact was off the east coast of a continent.). To dismiss an ancient catastrophe by ignoring erosion and deposition evidence is to have a prejudiced view. Wherever that impact was there was a mega-tsunami and no it wasn’t world wide. Please continue to objectively look at the evidence and watch out for prejudicial testimony arguing against that evidence. Since sea levels have risen several hundred feet, SOMETHING happened. Perhaps it is time to track down the way it happened and lay it out in an accurate description of population changes, human migrations and fauna changes like those seen at Gobekli Tepe.
Localised major flooding from glacier dam outbursts are expected during warming trends.
There is no significant evidence for impact yet.
@@gravitonthongs1363You might want to look into Chicxulub and Greenland craters. Both are ancient at 66 and 56 million years ago. Perhaps the Younger Dryas impactor was in the sea or into an ice sheet that we haven’t as yet found. In China there is a recently found crater that hasn’t been publicly dated.
@@AustinKoleCarlisle 90k year old thermokarst lakes are not impact evidence.
@@AustinKoleCarlisle I’m not sure if it’s due to your lack of comprehension, or just due to ignorance, but you keep making me repeat the same shit over and over.
During the time of the Younger Dryas, temperatures around the world rose for a period around 15h000 years ago. A rapid drop in temperatures in the Greenland around 13000 is matched by a rise in Antarctica around the same time.
If an advanced civilization developed during that time it could have migrated to Antarctica during that period.
The migration required to overcome a drastic change in temperature from one hemisphere to the other would have resulted in survivors that became skilled at navigation and astronomy.
During this time a seafaring civilization would have had easy access to South America and Africa. A long trip across the Atlantic or Pacific would not have been needed.
Thus the period from 15000 to 12000, 3000 years, relatively stable climate could have fostered an advanced civilization. This civilization would have been mostly wiped out by the catastrophic events and climate changes during the end of the Younger Dryas.
This theory would connect the dots.
nice summary....~ perhaps map depicting an ancient shorline that would somewhat represent a shorline with water levels over 400m lower, that would be an interesting visual layer...
Another great video, but I'm afraid I have to disagree with your conclusions concerning the YD not matching the Greenland Ice Data. The beginning of the decline to YD in Isreal is precisely the same as GID. However, only in the north did the climate return to Ice Age. Israel would remain temperate and experience gradual climate change. Otherwise, great work.
How come you aren't covering what is happening to the sites in Turkey? The Earthquake zone in around there.
You have raised some very interesting questions about the interpretation of Abu Herera that I suspect our technology is yet too primitive to understand.
VERY INTERESTING 🤔, well thought out.
Thanks for watching

Would you care to elaborate?

You're NOT paying attention. Is that the reason you are replying?
You definitely make some valid points. I
think of areas hit by wild fires and how they
look afterwards. And they are not as hot as the heat stated in the papers. It takes the
uses of modern equipment to move the
debris left behind from the devastation of
the fire. And even with that help it takes years to reclaim the land. And they aren't
having to hunt for food or plant crops. I
tend I tend to agree with your statement
about what the heat
would do to the people
as well as the land.
Are you saying that 500 years is considered "almost immediate" archaeology-wise? I think that the periodic changes is habitation and possible impact events could have been due to earth's passing through meteor showers on a regular basis in pre-history. That would explain the underground habitation as well.
A lot of excellent info. I think that when the error bars on the dates of those various events are taken into account, it leaves the door open. It’s also important to remember that the Comet Research team aren’t talking about a single impact that suddenly caused all the change. They’re talking about a series of impacts over thousands of years as the earth repeatedly encountered the returning debris of a large object.
We haven’t found one crater from the period let alone any series

Appears this proves, science is never "settled"
This is a fantastic video that sheds much light on what happened during the Younger Dryas. If only there were similar detailed studies available for North America. If there are I haven't seen any. A big question there is what happened to the Clovis people at the start of the Younger Dryas? As for Abu Hureyra, I don't see that an impact would have necessarily caused a significant interruption in habitation, but as you say more study is needed. There are so many unanswered questions. Keep up the good work.

There is a paper on this question. It estimates about a 50%+ decline in Clovis tools and I believe it is a 30%+ decline in Folsom tools.
Neither were 'wiped-out' as so many claim.
@@swirvinbirds1971 the decline of clovis tools may have simply been due to the decline of megafauna. Folsom tools are dated to 9500 BCE and 8000 BCE, well after the younger dryas. They are also smaller, which may simply be because most of the megafauna had gone extinct by then.
@@TonyTrupp agree. I also believe it could have to do with populations moving south.
Despite all efforts there is still so much to learn about this planet . This moment a lot of scientific work is in progress to understands the effects of the HongaTonga eruption from last year , to understand the past one must have fully knowledge of the present , right . Besides that I remarked something pecular at 10.58 in this vid , somewhat right above at the end of the red timeline , some wafflestructure near the bedding in or up the ground ?? Btw , this is an awesome vid about the timelapse of the younger dryas.
Thank you.
There are a number of different dating sources/techniques being used, each with a margin of error. For example how accurate is dating from an ice core vs dating from cave samples? Some of the discrepancies raised could be a result of this dating uncertainty; for example, if meteorite was a bit earlier and the settlement periods a bit later then a period of non occupation could be a result of the meteorite hit.
Quite logical . Those meteorites needed not to be big neither . Some lakes in W-Europe were formed by meteorites , never stopped the population to stay . Even nowadays peoples lives besides volcano's .
If the glacial maximum was at 100,000 years then focusing on the younger dryas
Window would be the smallest melt water event. The homo sapian having a 250,000 year window. The younger dryas would have been just kicking humanity while it was down. The 15,000 year window relative to a larger melt water event closer to 100,000 years.
My father was taught at school that the world was 4000 years old and that the atom was the smallest particle in the Universe ( whatever we think that is ! ) . Dad was just old enough to be called up for 1945 , was educated in the UK and got a scholarship . He was not a happy bunny to find out he had been lied to by the authorities ! Lol .
Well science moves on and we just have to have patience with how the data arrives and gets interpreted . Just realise that sometimes there are those who cannot accept the 'new wisdom' due to politics , religion and powerful inteletical bodies denying the bleeding obvious !
Great info as usual. Question. How do you explain global nano diamond distribution patterns as well as the Carolina bay impact structures in the bedrock if it wasn't an impact event that started the younger dryas cooling ?
Volcanic and general celestial debris.
90k year old thermokarst lakes are not impact structures.
I don't necessarily think its an either/or scenario. A sequence of events associated with climate, asteroid/meteor impacts, volcanic events and earthquakes. Maybe these events were interconnected like a domino effect. certainly our worldwide legends/mythology indicate a variety of localized calamities that amounted to something that affected much of the world within a geologically short time period. i love your balanced and open minded approach AA, keep up the fantastic work!

That's getting added to the lexicon.
Awesome!
👍
Excellent.
The cosmic impact wasn’t necessarily in the Levent. So saying Society was not affected therefore no impact seems simplistic.
Given the evidence for fluvial erosion in Northern Africa around 13ka, why do say there was no flooding in the fertile crescent? 🤔
It'd be interesting to get similar data across the rest of the world.
dont forget that the equator was 40 degrees off, north side of the himalaya was the north pole
TY 🙏🙏
Never thought I would unsub from this channel. Bye.
The science doesn’t meet with your ideology?
Max, do you dispute the Carolina Bays?
Nothing to dispute. They are obviously thermokarst lakes.
Looking at the graph it's interesting we're talking about the last warming and the rise of man into a different epoch? What about the much more gentile curve just previous? Especially since we seem to have inklings that probably isn't the whole story.
There's a good chance that we were on the upswing and likely advanced our position. Many places on the continental shelf deltas would have stretched for tens of miles and would have been the most prosperous and virile lands! Any water rise would be considered flood and some conjecture says mabe some meters quickly at a few times in the record. Pulse 1a and 1b for example. Something happened and I firmly believe we won't know just what until we dig the site's that are underwater in that timeline.
PS enjoy your thoughtful take on these subjects.
The global warming note seemed almost ironic on that graph that showed the majority of the time we had it warmer on Greenland then now..
The bread basket moved north along with herds. Then it got cold and it moved south before moving back north. What about the dry lake beds? You can see the karst wells just like in Egypt under the pyramids. Piecing together the climate explains a lot.
How do you explain the Channeled Scablands and the evidence of the cataclysm there?
Glacial dam release of meltwater from rising temperatures.
@@gravitonthongs1363 so you just go with the gradual erosion as opposed to catastrophic? The visual evidence doesn’t really support that and new studies are refuting it.
@@AgentChachi Sudden release of a great glacial dam is far more catastrophic than an impactor that is not even big enough to leave a crater.
@@gravitonthongs1363 and how many of these small releases occurred to create the features in the landscape we see, then? They would have to releases larger than estimated, to scar the landscape we see now.
@@AgentChachi Sudden release of a great glacial dam is far more catastrophic than an impactor. They occur more than once on most glacier dominated continental regions during a significant warming event. Volume estimates are consistent with observed effects.
Speleothem dating his highly inaccurate and the dates given from them could be completely wrong.
Have you got any sources I can read? I think they just have masses of data now. One set of data from one cave would not be credible but I believe there is a large and varied dataset and they’ve matched up many of the other climate spikes and troughs like the H1 event, so there are controls. But I’m looking into it further
@@AncientArchitects
Also, there is a book called “The Facts of Life” by Richard Milton and it covers the different dating methods and the problems with them.
I'm quite confused. How is climate data regarding Greenland relevant to this video 1:10 ? And how the heck am I one of so few to ask this?
In short .... Greenland has had fairly clean , unaltered by man , air ( ignoring volcanic eruptions ) .... It has also had ice layers forming every year since IDK .... By taking ice core samples in Greenland and matching ice core samples from elsewhere , especially closer to the Crescent , you will find some similar layers of un-normal deposits from the same time period . If you find anomalies occurring at the same time at great distances apart , then you can argue that a pretty much global events happened .... Don't kill the messenger !
