One of the counter-impact segments states that Hiawatha crater is too small to cause YD cooling. Could there have been multiple fragments, most of them air bursts, and Hiawatha was simply big enough to make it to the ground?
@@willyschanke399 News reports about the discovery include speculation that it could be as young as 12,000 years; these assertions are based on the Younger Dryas impact hypothesis. Fragments of charcoal up to about 2 cm (0.79 in) in size that were recovered directly from the ice at the tip of the Hiawatha Glacier, where the glacial outwash containing sand interpreted to be either impact melt or shocked metamorphite was collected, yielded an age greater than 50,000 BP. They interpret the charcoal to be wood that had undergone "thermal alteration."

@@swirvinbirds1971 The paper you refer to does not conclude that the crater is 50,000 + years old. The charcoal fragments may very well stem from old wood preserved in the ice for a very long time prior to an impact. Let me quote the last sentence of the paper you mentioned: "The large variety of Hiawatha impactite grains containing terrestrial organic matter with a likely age between 2.5 Ma and 50 ka support the conclusion in that the crater itself is not much eroded and very young, and the possibility of an age of less than 50 ka remains open." cosmictusk.com/wp-content/uploads/Organic-carbon-hiawatha-1.pdf
@@willyschanke399 Sure. But that doesn't point to 12,000 years ago either. You need proof to make the claim and this isn't proof of a younger dryas impact. It's proof that it is not a younger dryas impact. Nevermind impact specialists say the Hiawatha Crater is too circular to have been formed with an ice sheet above it. No data supports this being a Younger Dryas impact. None. And yet here we have everyone and their grandmothers claiming it's *proof* of a Younger Dryas Impact because of people like Randal Carlson and all the pseudoscience youtube channels like Bright Insight.
Thank you wholeheartedly Middlebury Environmental Geology for your video, I am hoping that from all of the ideas and the comments received, your students are encouraged to pursue their interests in this fascinating transitional period, to research, uncover and bring to light forgotten mysteries that may hold the key to our future. It has been the most interesting sets of replies and comments to a video I have seen for a long time, once more thanks for putting together and sharing.
The Glacial Lakes in N.America also catastrophically flooded onto land. Google Earth images are clear. Also visible are the Carolina Bays, which, I believe , are the smoking gun regarding Clovis. Check out Randall Carlson and Antonio Zamora on UA-cam. The ocean currents would also have been hampered by ATMOSPHERIC processes(smoke, cloud,snow) which would be brought on by impact.
Randall is a hack and Antonio only ties the Carolina Bays to the Younger Dryas as he needs a massive impact. Nothing ties the Carolina Bays to the Younger Dryas other than Antonio needs an impact. No dating, no nothing. The Clovis people did not disappear. Only 1 Clovis skeleton has ever been found and it was of a child. DNA tests show Clovis are directly tied to Native Americans in both North and South America. The Folsom spear point picks up in the America's where the Clovis point leaves off.
Swirvin' Birds Randall Carlson believes in his research into the comet which doesn’t make him a hack,the other theory which is the solar outburst theory both in my mind are equally possible according to the evidence,But both series rely on a single cyclical event ,in the comet theory it’s the toroid meteor group,And the solar outburst theory relies on a weakening magnetosphere and/or a polar reversal. Both theories are plausible only time will tell which one is correct for that particular event bitching about either one is childish debating both of them is intelligent
@@peterhansen2656 I don't care what Randall 'believes'. What I take issue with is the misinformation and lies of Randall Carlson. When you get some very basic stuff wrong you're a hack. Plausablitlity is not evidence. Major criticisms: Megafaunal extinctions were not synchronous. Extinction dates range from 400 years apart (N. America vs S. America) to THOUSANDS in the case of islands. Smaller mammals and other vertebrates were not affected by this hypothetical extinction event. Why? Why is this not even mentioned? Some extant megafaunal species such as bison and Brown bear seem to have been little affected by the extinction event, while the environmental devastation caused by a bolide impact would not be expected to discriminate. No evidence of population decline among Paleo-indians at 12,900BP No continent-wide wildfires at any time during terminal Pleistocene deglacation Iridium, magnetic minerals, microspherules, carbon, and nanodiamonds are all subject to differing interpretations as to their nature and origin, and may be explained in many cases by purely terrestrial or non-catastrophic factors. Something for you to chew on... ua-cam.com/video/ws9j3D6hQHA/v-deo.html
Swirvin' Birds I agree he might be wrong on some points and as I said you can choose between a number of theories I personally go for the solar outburst and stating your facts is no problem for me, being mean-spirited is. You can extrapolate different viewpoints from the same graph it doesn’t mean taking a section invalidates it and there still was an extreme drop over a very short period of time which lasted 2000 years but the initial drop was very quick the fact that it has happened in other periods in history supports the idea that it’s a solar outburst which happens on a regular basis.Go and look at the work of Ben Davidson o.n the subject very compelling.
@@peterhansen2656 I would go with a solar flare event before I would buy into a Younger Dryas Impact personally. It lasted about 1,300 years... An impacts effects would dissapate much faster than that. IMO a Saddle Collapse of the Ice Sheets with a shutdown of the Atlantic conveyor is perfectly able to explain the meltwater pulses of which the Younger Dryas is just but one of several meltwater pulses from that time period. www.nature.com/articles/nature11257 www.ncbi.nlm.nih.gov/pmc/articles/PMC5053285/ ui.adsabs.harvard.edu/abs/2014AGUFMPP51D1153I/abstract www.sciencedirect.com/science/article/pii/S0012821X17303205 I am mean spirited towards him as he has spread a whole lot of B.S. while mocking 'mainstream science'.

A snake oil salesman profiting off of the spreading of gross misinformation.
This video sets up a false dichotomy, by asserting that impact theorists deny flood water effects. Evidence of fires, floods & impact proxies could all be triggered by impacts on ice sheets & elswhere.
Something called, “fallout” or “fire and brimstone”, like you said floods and if we rotate on this planet I’d look for multiple impacts, who says it’s just one comet? From Greenland to America we are peppered with impacts.
If you can get your hands on a book by Walt Brown. He explains how there is no continental drift. At least not the way they want you to think. There was a mega continent. And the reason they seem to match is that’s where it split down the middle. The Atlantic seabed is where it blew out. I mean Empire State Building size chunks. That’s where the asteroid belt came from. It’s an anomaly in space. They aren’t everywhere. Not in a sphere but a disc. As the earth turned and this stuff blows out it’s also traveling through space. And we keep running back through the debris. That’s where the water came from, subterranean. And the rocks-asteroids and the comets. That’s why when they test comets it’s the same stuff as in earth. Cuz that’s where it came from. And the earth sucked in directly opposite and the Pacific holds the run off. And why we have the ring of fire. Makes sense.
I remember in school it was gospel from the experts that human hunting caused extinction of the megafaun. Even as a child, this idea was suspect. All you had to consider was, what about the African large animals that still exist? Weren't they hunted as well? Why were the extinctions regional, animals mainly disappeared from North America and to a lesser degree Europe and Asia?
Exactly. What I was thinking. How come to this day the megafauna in Africa hasn’t been wiped out? They have a answer for that, they had a brainstorming session to come up with a comeback for when people with half a brain question their narrative. Also. How dare anyone question the story they are making up on the spot as to what it all means. Some people believe every word that comes out of their mouths as archaeological fact. They probably watch CNN nightly also so they are used to being lied to and not having any idea. Sad state of affairs.
@@conceptstillsandmoti another one is. The gods fell from the sky. I think that means fireballs fell from the sky. Comets or meteorites or asteroid. There must have been fire in the sky.
They discovered a human bottle neck around 15-12kyrs ago where the scientists believe the total human population was reduced to about 5 to 50k individuals and were from Kenya Africa.
The amount of water injected into the atmosphere from a Greenland glacial impact would have it's effect as well. The ice sheet would have reduced the size of the bedrock crater too.
As we learn more about CME and solar outbursts, we realize that it is very difficult to distinguish them from impact events, and they may even accompany one another with high-level events.
Alan Land In my opinion, A Solar Outburst Event, (seeming to be a cyclical event. of approximately 12,000 years. Half a “Great Year” ) best matches the mythology, geology and historical climate data. A pattern of cyclical catastrophic, climate events, . Cosmic impact, is not a cyclical event. All the impact glass, nano diamonds, and vitrification, are also explained with such an event. As well, as the rapid melting of ice sheets.. The petroglyphs of plasma formations, recorded what ancients saw in the sky .. a worldwide phenomena, suggestive of shared experiences. Formations of plasma in the sky, seen near the equator are only possible with an extremely weakened magnetosphere. Not the result of a comet strike . Solar outburst, seems to be the Catalyst and accompanied by a weakening of the Magnetosphere. Allowing Incoming radiation, essentially heating, the Earths Core. Magma rises, climate chaos, and earthquakes, the result. It is also possible, that this could be a catalyst for magnetic Pole reversals. Just like we are experiencing now.
@@rikkispence7049 Hi, Rikki. You mentioned mythology. A CME (alone) does not explain much of what our ancestors recorded. It would appear you are familiar with Anthony Peratt's work, and perhaps that of Dave Talbott? One cannot ignore all the clear references to the role the planets played. There was clearly much more going on.
@@rikkispence7049 CME's don't explain the Carolina Bays and Nebraska Rainwater Basins. Antonio Zamora's ice boulder hypothesis makes the most sense for the formation of the bays/basins. An object hit the North American ice sheet somewhere over what is now Michigan. It launched ice boulders across the continent, creating the bays, and killing pretty much anything on the ground.
our ancestors of screaming from the grave. Nobody can explain the deep-sea Canyons. I've never heard anybody read any research about u.s. Navy tracking magnetic pole reversal that evidence of shocking to me. Text types of radioactive isotopes and fusion tracks found on the moon and on this planet. With fossils with animals that crawl into shells to live as their shells oriented himself with the magnetic field, deep-sea mud core samples will explain that. Too much evidence to say that the sun doesn't Nova on a cycle
Yeah like the suns cycle. We can see other stars doing this in our own Milky Way galaxy wild thousand light-years out twenty-four thousand light-years out 36,000 come on
This video doesnt even touch on the suspected taurid comet swarm. Being comets they would detonate in air with some of the more rocky parts of the main impactor making contact with the ground. Also, being a swarm their would've been multiple hits like a shotgun blast of devestation
The black mat, the black mat, the black mat.... Pretty hard to get that from fresh water flooding. There was a big ( or multiple ) impact event around that time
@@swirvinbirds1971 Yes but the black mat dated to the younger dryas was when many megafauna and Clovis culture became extinct so it must have been a major event. I know there were other black mats.
@@williamgreene4834 The culture did but not the people. Clovis DNA is tied to Native Americans in both North and South America. We also have the Folsom culture that overlap the Clovis in North America and continues on after. The Megafauna? About 75% had already gone extinct before the Younger Dryas and many still live in North America today.
Most large impactors break apart into multiple fragments prior to impact. There was also an ice sheet over 1 mile thick at the site(s) of impact. This is conveniently not mentioned in the impact rebuttal. An impactor, or impactors, could have had massive effects on the planet without leaving a lot of physical evidence or minimal evidence such as a crater in Greenland that appears too small. Unless, of course, you consider the total diameter of the original impact crater in the 1+ mile thick ice sheet may well have been 2-3 times the diameter of the crater as observed today.
Chondrite meteors (meteors from our star) have iridium, Nano-diamonds, platinum and Aluminium-26 Chondrite meteors ALWAYS blow up in the atmosphere as they're negatively charged our atmosphere is positively charged The main body blew up likely over Saginaw Michigan Impact Given Platinum is highly valued look at the ore found in this platinum mine in Littleton, Colorado. It has all the characteristics of Chondrite. Meteor formed in the core of the sun which interestingly has Amino acids. no other meteor has them.

Solar Micro Nova. Look at the isotopes in the data that can only come from a nova. And with the recent discovery that these cannot escape the ejected shell in a nova, the isotopes MUST have come from close by. That is, our sun. And it couldn't have been a bigger nova or we wouldn't be here.
They have not found a crater over Tunguska. It looked as though the object broke up in the atmosphere, and the shock wave did the damage. Look at the Shoemaker Levy 9 impact on Jupiter. Nobody ever thought they would see that.
I think the presence of hexagonal diamonds is a dead giveaway of an impact event. They where fond bothat the Clovis site in Tennessee or Kentucky and in Greenland. They only form massive impacts.
@ 25:57 In truth there are no "other directions". The amount of energy needed to melt the humongous amount of ice (note that the two YD meltwater surges raised the world's oceans a total of 400 feet) had to have come from an extraterrestrial source. The onset of the Younger Dryas heating events were simply too sudden for more geologic processes to be responsible. We also have to remember that the YD events were traumatic in other ways besides mere climate change. Large numbers of megafauna species died off, and many of the siblings of these same species are quite well-adapted to our own relatively warm climate. The conclusion has to be that it wasn't the climactic changes themselves that killed off all these species, it was other, as yet unidentified trauma also associated with the YD events that killed off the megafauna and the Clovis culture. Large scale fires and floods are two among many such possibilities. It is quite likely that the extraterrestrial body that impacted the earth broke up before entering the earth's atmosphere, much like Comet Shoemaker-Levy 9 did in 1992 before it impacted Jupiter in 1994. Much of it must have either exploded over the Arctic ice cap and released large amounts of heat generated by friction with our atmosphere (like the Tunguska 1908 object) or impacted the ice cap in various locations, including the impact craters we can see on Greenland and possibly British Columbia. Claiming that an event is very low probability is not the same as claiming that it is impossible. Strange, low-probability events do happen. People do win the lottery. They also get struck by lightening. Both are very low probability events. It's also possible that we simply don't know how probable such an impact event might be because our astronomers aren't able to see most such objects. One thing's for certain, our near neighbor the moon is covered with many impact craters, so we do know that impact events do occur with some frequency in our region of space.
If incoming asteroids carry a large electrical charge differential from that of Earth, then there will be a massive electrical discharge shattering the asteroid as it nears impact. This phenomenon may indicate that the lack of craters does not necessarily indicate a localized destructive event. The Dragonstorm Project - sites.google.com/site/dragonstormproject/Home hypothesizes a fragmented asteroid hosing a stream of high temperature electrical plasma discharge from central Mexico to the Great Lakes, like a welding arc melting the tops off mountains and leaving large splatter patterns in the landforms of the Great Lakes region.
All one needs do is calculate the amount of energy it would take to melt 18*106 km³ of ice and understand that the answer is only for the Laurentide ice sheet. Four of the five northern ice sheets melted within a few hundred years at most. Our sun cannot put that amount of energy onto the surface, even with a coronal mass ejection. Yet the Greenland ice sheet didn't melt along with the other four? Given the trajectory shown by the Carolina Bays riddling the east coast of the U.S.A. and the basins on the North Slope, these bodies came in at a relatively shallow angle. That means they would have traveled in an easterly direction through the atmosphere for a short time prior to impact. In the Tunguska event, it was shown that ground temperatures directly under the trajectory of that body reached ten thousand degrees celcius. That would have melted almost all of the Cascadia sheet and most of the Laurentide, as well as pooling the water quickly enough to create the Yakima floods. There were more than likely a few chunks that landed above Europe and Asia on that side of the Northern Hemisphere. Google Earth zoomed out over North America will immediately show not only large circular bays along the northern shores, but monsterous water flow lines all along the southern ice limit. Both sheets melted almost immediately and flooded the entire continent, washing anything on the surface right out to sea. Probably why we dont' find the bones of the billions of megafauna that died. Though they do dredge them off the North Sea floor.
@@TheDeadlyDan Actually you don't need to account for all the ice melting in one go. The likely hood is that the ice was already extremely unstable with massive glacial lakes containing billions gallons of fresh water. All we need is an impactor or impactors large enough to melt the ice dams and there you have your flood. I would say that this theory is pretty much in its ascendency now. Some mainstream will argue against but probably only the ones that don't like actual science. For certain sure, the, the humans ate all the megafauna theory is preposterous.
Discussion completely ignores the Carolina Bays mystery as well as the fact that what ever the cause there was a dramatic extinction of fauna immediately after the event! Possibility a combination of occurrences, the early warming starting to impact the ocean conveyer flow and a impact on the North American ice sheet exacerbating the final result.
To have the famous wooly mammoth to freeze with food still in its mouth would it not seem likely a solar flare hit the ice pack causing an instant flood and the open vacuum of space following the flare allow the coldness of space to instantly freeze afterwards?
Evidence looks like it suffocated to death first. Then froze solid in hours still with the summer flowers. Have wondered on the cause of death of The Beresovka Mammoth. And whether it was that something punctured a hole in the atmosphere somehow leading leading to the coldness of space rushing in. Certainly have not heard any explanations as to what may have caused its death and preservation so quickly. They found another Mammoth, with its body in one position and its feet in another, looking like it was completely blown off its feet, by a shockwave?
I am an expert on the subject since I just typed it in on wikipedia to see what the term meant and my ruling is the impact/s hypothesis is right on especially with carolina bays and other evidence. Carolina bays marks were likely from ice chunks and the elliptical shapes point to the general area up above or near great lakes northern area. Randal Carlson got lucky in his guesses.
There is evidence of massive flash flooding in the state of Washington. I have a crappy memory so I can not tell you the name of the Geology Professor nor the college he teaches at. But he has been trying to get the point across for years. The state has a lot of volcanic activity. Massive ancient lava beds. In one region there layers of sediment have been cut through down to the ancient lava beds. On each side the edges are sharp and very steep. If you find his UA-cam site he always uses a chalkboard and he is quite tall. Thinning hair. Because of Covid he did start using a marker board and videoing from his backyard. As far as the impact hypothesis. After scientists watched a broken up comet hit Uranus (I think that was the planet) in a line of multiple impacts some proponents of that hypothesis started thinking multiple impacts to the ice sheets in the Northern Hemisphere could melt a lot of it but not necessarily all penetrate them deep enough to leave a crater. Hiawatha crater may be only part of the impact event or a separate impact event. They have been trying to figure out what caused the sudden spike in temperature just before the Younger Dryas for a long time. One of the things they use against an impact event has always been the lack of a crater big enough. Again, if it was multiple impacts across a large area and into ice sheets about 2 miles thick the smaller bits might not leave any craters. Parts may have hit in the Northern Pacific and Atalanta as well. But nix the multiple impact hypothesis and what are they left with? A huge solar flare, changed in the planets tilt for whatever reason, and/or massive volcanic activity. We can’t, as far as I have heard, chart ancient solar flare activity. The Earth’s axis does change but that has not been known to cause heat intense enough to leave behind ash in such a thick layer. I have not heard that they have found, yet, volcanic activity from the time period that could have caused the ice melt they know happened before the refreeze. Because of ocean levels since only fairly recently have they realized people likely walked into Australia and Britain and that there didn’t use to be much water where the Mediterranean is. They did not know there was a Super Volcano under Yellowstone National Park and it had left a trail as the Continent drifted ever so slowly across the hot spot. Nor that a Super Volcano had blown in Arizona. Or the crater in the Gulf next to the Yucatán Peninsula that was likely made by a really big impact that caused a global bear extinction event and wiped out the dinosaurs. It is good to critique theories. But to say not possible until actual proof of what caused the sudden massive melt that raised ocean levels by 250-500 feet (likely the reason for the ancient flood stories around the globe), left that significant dark layer, and the extinction of many land animals and plants around the globe, I think is wrong.
10:00 Makes sense to me that there was a major flooding event that happened ca. 12,800 years ago, disrupting the gulf stream, the world cools, glaciers build up again and around 8,00-9,000 years ago glaciers advance, pushing previous evidence for the flood out to sea.
Good job guys. The only thing that could have caused the younger dryas was an extraterrestrial event. The devastation left in the Washington state scablands can only be explained by this horrifying conclusion. By horrifying I mean the fact that this flies in the face of the dominant paradigm that is so beloved by orthodox gradualist lemmings. It takes a generation for old false theories to die and it will only happen with this kind of vigorous debate which can finally bring out the truth. Thank you all for doing this. You all are awesome.
The Channeled Scablands were formed by Glacial Lake outbursts not an impact. Nothing in the Channeled Scablands ties it to an impact. Nothing. It's not even dated to the right time period.
@@bobbyt9431 Randall Carlson misinformation is just out of control isn't it? Freaking drives me crazy so many buy into this man that has been proven wrong time and time again.
Before the Holocene the average temperature was lower til the younga Dryas THEN they spiked indicating massive melting THEN the temps dropped for over a 1000 years THEN something happend to drive the temps far higher than what they where BEFORE THE YD and then the earth gaind 400 feet of sea water AND THE average temps are now FAR HIGHER than they where before the YD what ever hapend to earth ALSO affected the solar system
unfortunately, the class has ignored publicly-available evidence of solar-caused massive cooling of the earth at that time. The evidence is from analysis of lunar rocks brought back to earth during the Apollo missions to the moon 50 years ago. These rocks were tested and found to contain glasses containing internal x ray tracks created by solar super flares or even a micro nova from that same era. And the sun, as we know, is much more capable of such powerful events, that could have caused large scale radiative dimming of the earths surface.
I'm by no means a scientist, but if there were significant changes in solar radiation at that time, wouldn't there be evidence all over the planet rather than just North America? I'm just speculating here - as I said, I'm not an expert at all.
That was a really good summary of the science👍👍 THANKS😊 my only reservation was the young lady who seemed to want to make a them and us argument out of who was right🤦 they’re competing hypotheses you are describing, without more data you can’t say who’s right🤦 all sides have excellent ideas😊

Ground Zero - Hudson Bay. Dec 17 2020. Is the Hudson's Bay the impact/blast crater that started the deluge which began 12,000 years ago? What are the pieces I've put together? Lots of pieces, iron fragments of an asteroid have been found, the last chunk which was found at the 12,000 mark and had been tested to 12,000 years BCE. Over the past hundred years people thought they were iron meteorites, or asteroids. Well, there is a problem with that, there are no craters to verify that fact, and if an asteroid hit the earth it would disintegrate. Most piece of space rocks are part of the meteorite after it explodes in the air. So why is there so many pieces of iron asteroid found? The asteroid breaking apart so close to the surface, would have lead to a number of possible bursts once fragments hit the ice. Strange damage to the ancient structures built before 12,000 BCE. Several of these structures have significant damage done at the tops of the buildings which are on the mountains; pre-Aztec, as one archeologist stated looks like a quasar or a magnetic pulse hit it all at the same time. It is true of the damage, these structures still can not be repeated by us to this day. We do not have that power to damage some of the structures noted in the presentations. Both in the middle east and in Peru. The damage to the structures in Peru is north to south, the structures in the middle east is west to east. Earthquake proof buildings. Russian asteroid, where 200 people were injured due to flying glass after the shock wave from the asteroid exploded, taking 90 seconds to reach the victims. A huge blast at some considerable distance. Why couldn't the damage be more rational like a blast from an asteroid, instead of some alien ray gun? We have to look at the Gulf of Mexico, confirmed impact which wiped out the dinosaurs, the crater is there, we know it, it is a fact. This time, when the asteroid went to make an impact, it hit the ice and exploded where the Hudson's Bay is today, sending fragments all over central US. The blast wave, rapid heat, fast rising oceans where cities are still covered under the ocean, and the deluge events. The ice was vaporized and saturated the atmosphere. It took 2000 years from ice age to something of what we have today. 10000 BCE., humans had to start all over again. Our Ancestors before that time lived for 1.2 million years. Theory of impact is in place and seems to be 4 crater bursts, Iron deposits? less gravity. Funding for the Younger Dryas Impact Theory was discontinued because the impact site could not be determined. All the enchanters, professors, Archeologists, Anthropologists, Geologists, and all the magicians of the world could not find the blast site in North America, When there has always been a blast field with 4 craters, which make up the Hudson's Bay.
so if an impact happened in Greenland thru an icesheet. Besides the instant change to steam and blow up thru the atmosphere. the resulting shock wave would shatter the ice sheet that would rain down on the open land covering all that lived. The resulting down draft after the first blast up would bring extreme cold down in areas which could be the reason we find flash frozen mammoths buried.
You may want to include the fact that Clovis points have only been found BELOW the Black Mat layer. Also, and impact on the ice sheets would result in huge amounts of melting very quickly - also producing freshwater infusion into the northern oceans. Impacts on the ice sheet directly would mute any surface craters, leaving little evidence. Thus, glacial outburst flooding and the impact hypothesis aren't competing, they are complimentary. It is difficult to imagine the energy required for that level of melting in such a short timeframe without invoking one or more impactors on the ice sheets themselves. An extended rainout would exacerbate this effect. Furthermore, evidence of massive flooding can be found all the way from the channel scablands of WA to the finger lakes of NY. The Missouri and Mississippi rivers are evidence on their own. These are 'misfit rivers.' Meaning that the size of the river basin (bluff to bluff) is much too large to have been caused by today's typical flow rates, regardless of the time allowed for that flow to do so. These two theories need each other. Good work presenting both sides of the argument. Well done.
If anyone thinks Volcanic processes can't produce and distribute globally, nanodiamonds, platinum, iridium, shocked quartz etc, they weren't paying attention back in January when Hunga Tonga huapai did just that. We are still experiencing the purple sunsets eight months later. Imagine that one times 100. That's a Supervolcano like the one that left Hiawatha. The release of magma stored chemical energy equivalent to about 1000 GIGATONS of TNT, in one or two seconds. A high volatiles magma chamber like a supercritical boiler over ten km in diameter exploding at supersonic speed. The Tonga example was just eight cubic km of magma. It got ejected as a 3000C vapour of liquid and gaseous ionised rock at Mach 5, and 10s of thousands of lighting strikes per second burned through the Five hundred km wide umbrella for an hour. What do you think 1000+ cubic km of magma created in the tight pressure injection of water Subglacial continental regime detonating would do by comparison? Physical processes guarantee that ice sheet collapses are neither gradual or boring.
A very concise and objective analysis, thank you. There are many curiosities about this event in our recent history that are difficult to ascertain, short of the obvious fact that something catastrophic happened. Silt and Bone washed up against the mountain ranges of North and South America, megafauna completely wiped out of virtually all Western continents, leaving only Africa and parts of India least affected. Looking at what we know, comets tend to break up before impact, so a smaller crater somewhere does not necessarily mean anything if larger pieces slammed into the thick ice sheets, leaving no trace, flash melting trillions of gallons of fresh water and setting fire to everything else. The only humans that survive an event so tragic are tribal societies, currently living off the land and politicians. Personally I believe that a highly advanced global civilization existed before that time, very different from ourselves, yet possibly even more advanced than us. The original human foundation, passed down to us through legend and myth. Even our Christian myth of Lucifer, the morning star, "who's countenance outshined the Sun" is a very accurate description of what a massive ball of ice and rock would look like moments before impact. Indeed future humans looking back 12,000 years from now would be challenged to find much remaining besides plastic melted into that black mat layer. Everything would be scrubbed away by floods and fire and glaciers, volcanic turmoil and possibly war. Knowing their world was about to end very likely could have ended up with rival powers at each other's throats as legend has it. Punished by God for their selfishness. Few people really realize what an impact of that magnitude would touch off across the globe, not just biomass burning and flash melting of two mile high glaciers, but major geologic instability, i.e. earthquakes, and global volcanic activity. I mean the Fukushima earthquake alone shifted the Earth's axis by 6.5 inches. A blip on the magnitude of scale... My question is what is the possibility of the turning point caused by major solar activity, CMEs, possibly even micro nova, and magnetic reversal creating even more catastrophe than a large impact, since the evidence is so scarce I would like to know your thoughts on this? Thank you
I think this was a good debate. I found that proponents Against the YDIH relied on evidences found by creditable people that had questionable sampling techniques.
Impact theory is not opposed to a glacial flooding. The heat from a cosmic impact is what is required to melt the glaciers. Plus it explains the black mat. This is a false dichotomy. Fire - flood - freeze. Check out the review of papers on the YD by Martin Sweatman.
...it's awesome...if it was a catastrophic event that caused the YD...wouldn't we need another catastrophic event to cause the one that everyone says we are headed for? they are cyclic maybe the cycle attracts catastrophe...
Interesting and plausible. But there is a vast literature on this subject relating the Younger Dryas to glacial Lake Agassiz. So I also doubt this research will go far. Well done and well presented.

Look what happened when we witnessed a comet pass close to Mars, a comet tail could displace atmosphere , cause electrical discharge, and transport and instantly freeze forests and megafauna ?

Well, something caused the Younger Dryas! If a strong logical explanation (with some supporting evidence), is argued against, then you better have your own hypothesis as to what caused it. So far, opponents of the extra-terrestrial explanation have not countered with anything substantial. This makes me very suspicious that they are wrong in their objections and in fact are holding back the probable explanation of the Younger Dryas.
They are hiding the Alpha and Omega. A plasma discharge glassing Atacama and recorded at Nazca (lines) by removal of the iron spherules that were FUSED from silicates. These magnetic spherules are used in secret societies and you can see they were collected at Nazca and used extensively leading the elite to have cranial deformities associated with heavy metal poisoning.
It would be interesting to know if these spherules also can be found on the lunar surface... ...oh what, we already know the answer. How is it that they also appear on the moon?
The Laurentide Ice Sheet was over a mile thick! Between multiple impacts on the Ice Sheet and atmospheric explosion from a break-up of the impacter, there wouldn't be terrestrial craters. The Carolina Bays illustrate this impact on the Ice Sheet. The heating, shockwaves, and flooding from melted ice as well as torrential rain from the vaporized ice would have been sufficient to affect weather patterns as well as directly and indirectly cause the mass extinction of the megafauna. Impacts in the Hudson Bay and Great Lakes areas would have been sufficient to cause this scenario. Greenland impact is too old as the ice covering it is older than Younger Drias. The impacts on North American Ice could have sent enough fresh water into the North Atlantic to disrupt ocean currents as well. IMO
Forget the crap you see on TV, a comet is moving at roughly 300km per second, and enough of it can and will survive the death dive into a planets atmosphere to be able to cause catastrophic damage. Most explode above the surface though, composition and size really matter.

It makes the viewer question how viable the science department is at a liberal arts college in Vermont. The topic is too complex for these apparent non-majors to make the school look good in any manner but dilletantism.
The large cooling of some substantial part of the northern hemisphere (-8 degrees mentioned here for Greenland) combined with the tiny cooling of only -0.16 degrees global average per the huge 24k year global multi-proxy analysis (a synthesis of a few dozen separate proxy analyses all around Earth that took scientists 7 years to do) could only have been caused by a sudden stop, or big reduction in how far north it goes, of the powerful Atlantic current because nothing else would have cooled a few percent region of Earth in the Atlantic region and not cooled anywhere else. Volcano or asteroid impact global dimming wouldn't do that. An asteroid impact might well have caused the current to stop or change. What happens is that less heat gets carried north (it's 6 petawatts right now) causing north to cool and the tropics, maybe south too, to warm but because most land is in the north, most ocean in the south, the land cools more because ocean mixes a bit of its huge thermal capacity, so overall there can be global cooling even without Earth getting heated less than before. However, what can happen if this switch of heat transfer warms the north less is that there can be more ice & snow because, as with the thing just mentioned, most land is in the north, most ocean in the south. Since ice & snow are reflective there could become genuine GLOBAL cooling due to more sunshine reflected.
Zamora et al have proposed an impact on the southern edge of the Laurentide ice sheet, which caused a rain of ice chunks to fall up to about 1500 km away, causing the so-called Carolina Bays, with similar features in other areas such as the Gulf of Mexico and Nebraska, (en.m.wikipedia.org/wiki/Carolina_bays) as well as a release of ice and melt water into the north, and a distribution of water in the stratosphere that would have caused global cooling for several years, and associated rains . Associated impacts in other areas such as Argentina at the same or nearby time would have caused global fires. OTOH, the presenter of Ancient Architects on UA-cam notes that the dip in temperature was not all that sudden, and matched several previous episodes. Related - the Scablands and Dry Falls region of Washington State does provide evidence of extremely large releases of water on numerous occasions, with flows hundreds of times greater than any known river, as a result of melt water lakes breaching dams in the edge of the ice sheet. These releases were hundreds of feet deep and miles wide. Just the backflows filled the Willamette Valley of Oregon over 400 feet deep, and the flows also caused "ripples" in sandbags in the Columbia River with periods of several hundred feet and depths up to 100 feet.
@@GaryBickford I take Svensmark with a pinch of salt. 14 years ago he said CO2 has an insignificant effect on climate warming. Perhaps he should be in the Heartland Institute for Climate Denial ?
If you are going to argue the pros and cons of The Younger Dryas Impact Event, don't do it with students who are not familiar with the exhaustive evidence that has been researched and submitted. Especially, don't make suppositions that are completely false about the the claims of the Comet Research Group. This is not an educational debate. It's a bunch of opinions based on limited knowledge.
A third hypothesis for the cause of the Younger Dryas event can be found with the Farsight Institute remote viewers who say humans accidently caused an explosion so large it devastated the entire world. Apparently a civilization existed even more advanced than our own but ended up having technology get the better of them. As a consequence to this catastrophe, their island continent sank and sent the oceans across the lands in a succession of mega tsunamis from every direction. There would've been drastic changes to ocean currents and probably worldwide storms until it all resettled. This "hypothesis" actually makes sense to the evidence seen and should be considered by academia . . . but guess what? Remote viewing is just conspiracy nut pseudoscience and cannot possibly work. Anyway . . . our "known" history has not seen a large scale landmass and oceans, into motion event but they do occur and might even be our biggest natural threat. There's virtually no size limit to earthquakes and the their subsequent "mega" tsunamis but we don't hear much about it. Psychics are saying they see California cracking into the ocean in the near future! I choose truth for myself, it's so much more interesting!
Thus, while we can give the class an "A" for their production of this high quality video, we must mark them down for "not" uncovering that the Younger Dryas has been marked in time, as occurring repeatedly, every 12.6 thousand years, or so. That the event repeats is the most significant "fact". Almost as important is the fact that the Apollo Astronauts found massive evidence on the moon over 50 years ago that the event causing the Younger Dryas was a solar micronova. Nor has the professor of this class seen fit to help all of us by producing the links to: Dr. Anthony Perat, Dr. Robert Shock, the Diehold Foundation, BenDavidson's SuspiciousObservers.org, Dr. Wallace Thornhill, Dr. Donald Scott of TheThunderboltsProject, Dr. Michael Claridge of The Safire Project... and so on, for leading all of us to the significance of all this. Traditional academia, it seems, is incapable of actually "providing" useful education in the solutions to real problems. So we might also include Google in our thanks, for keeping this forum extant. Of most benefit to all of us is the Safire Project, which has demonstrated experimentally here on earth how to create sustainable fusion power. It could lead our descendents out of darkness the next time the sun throws a conniption.

Thanks to geologists, we think that all living things on our planet have the most to fear from an asteroid impact. But when we look at the many horizontal layers that we find everywhere on our planet, we clearly see the effect of a repeating cataclysm. These disasters are mentioned in ancient books like the Mahabharata from India and the Popol Vuh from the Maya. They tell us about a cycle of seven disasters. Certainly, a cycle of regularly recurring, thus predictable but inescapable global disasters cannot be caused by asteroid impacts. The only possible cause is another celestial body, a planet, orbiting our sun in an eccentric orbit. Then it is close to the sun for a short period and after the crossing at a very high speed it disappears into the universe for a long time. Planet 9 exists, but it seems to be invisible. These disasters create a terrible natural cataclysm with much flooding and a cycle of civilizations. To learn much more about the recurring flood cycle, the re-creation of civilizations and its timeline and ancient high technology, read the e-book: "Planet 9 = Nibiru". This book answers many of your questions about our past. It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9
Because with few to none scientific basis regular people are easily fooled by snake oil salesmen like Al Gore. Science isn't established nor consensual so you gotta listen to both sides and that side is not only not shared by geologists, and you didn't even checked what the geologists say. You have no idea what you are talking about!
Nice thoughts but you have missed looking at a Mini Nova of the Sun where all these glassy carbon spherules, the rounded magnetic particles, the nano diamonds and the iridium spikes will all be found - Look at the Safire project's latest results. Wildfires would result and probably widespread glacial melting so all your observations would be correct under a mini nova basis - which is also a repeating phenomena.
At approximately t=5 minutes you speak of "theory 2, a bolide impact" as an alternative to "theory one, a stop of the thermohaline circulation because of meltwater dumped into the ocean". That logic is flawed, those theories are not necessarily alternatives, theory 2 is one of the possible causes for the event in theory 1. Both may have combined.
Yes it's possible that meteor impact at what is now the south tip of Lake Michigan burst a huge ice dam that was holding back Lake Agassiz causing a flood of fresh water into the Atlantic.
Totally down with the extra terrestrial.. 'impaKtor' . It was a great battle of the aliens vying for control of Earth. The meteor was a missle strike clearly. Nukes and helium fullerines as explosive projectiles...
Great video - thank you. @ 9:50 Small niggle... 'Ms. Kermit' could improve by adapting that seemingly, habitually, postured delivery - it is distracting. Content though is excellent.
I'm not surprised you didn't include the solar micronova outburst that may have been the reason for this. It won't become part of mainstream science for a few years but it explains all of this evidence and most of the dark matter conundrum.

One of the counter-impact segments states that Hiawatha crater is too small to cause YD cooling. Could there have been multiple fragments, most of them air bursts, and Hiawatha was simply big enough to make it to the ground?
The Hiawath Crater has had better dating done. It is 50,000 + years old. It is a pre-ice age impact.

The Glacial Lakes in N.America also catastrophically flooded onto land. Google Earth images are clear. Also visible are the Carolina Bays, which, I believe , are the smoking gun regarding Clovis.
Check out Randall Carlson and Antonio Zamora on UA-cam.
The ocean currents would also have been hampered by ATMOSPHERIC processes(smoke, cloud,snow) which would be brought on by impact.
Randall is a hack and Antonio only ties the Carolina Bays to the Younger Dryas as he needs a massive impact. Nothing ties the Carolina Bays to the Younger Dryas other than Antonio needs an impact. No dating, no nothing.
The Clovis people did not disappear. Only 1 Clovis skeleton has ever been found and it was of a child. DNA tests show Clovis are directly tied to Native Americans in both North and South America. The Folsom spear point picks up in the America's where the Clovis point leaves off.
Swirvin' Birds Randall Carlson believes in his research into the comet which doesn’t make him a hack,the other theory which is the solar outburst theory both in my mind are equally possible according to the evidence,But both series rely on a single cyclical event ,in the comet theory it’s the toroid meteor group,And the solar outburst theory relies on a weakening magnetosphere and/or a polar reversal. Both theories are plausible only time will tell which one is correct for that particular event bitching about either one is childish debating both of them is intelligent
@@peterhansen2656 I don't care what Randall 'believes'. What I take issue with is the misinformation and lies of Randall Carlson.
When you get some very basic stuff wrong you're a hack.
Plausablitlity is not evidence.
Major criticisms:
Megafaunal extinctions were not synchronous. Extinction dates range from 400 years apart (N. America vs S. America) to THOUSANDS in the case of islands.
Smaller mammals and other vertebrates were not affected by this hypothetical extinction event. Why? Why is this not even mentioned?
Some extant megafaunal species such as bison and Brown bear seem to have been little affected by the extinction event, while the environmental devastation caused by a bolide impact would not be expected to discriminate.
No evidence of population decline among Paleo-indians at 12,900BP
No continent-wide wildfires at any time during terminal Pleistocene deglacation
Iridium, magnetic minerals, microspherules, carbon, and nanodiamonds are all subject to differing interpretations as to their nature and origin, and may be explained in many cases by purely terrestrial or non-catastrophic factors.

Swirvin' Birds I agree he might be wrong on some points and as I said you can choose between a number of theories I personally go for the solar outburst and stating your facts is no problem for me, being mean-spirited is. You can extrapolate different viewpoints from the same graph it doesn’t mean taking a section invalidates it and there still was an extreme drop over a very short period of time which lasted 2000 years but the initial drop was very quick the fact that it has happened in other periods in history supports the idea that it’s a solar outburst which happens on a regular basis.Go and look at the work of Ben Davidson o.n the subject very compelling.

There is a lot of speculation in this video.
That’s exactly what happened, regardless of authors cognitive level...
Exactly, the climate change has to be the result of an unlucky confluence of events. How do you explain the Carolina bays without an impact event?
Something called, “fallout” or “fire and brimstone”, like you said floods and if we rotate on this planet I’d look for multiple impacts, who says it’s just one comet? From Greenland to America we are peppered with impacts.
If you can get your hands on a book by Walt Brown.
He explains how there is no continental drift. At least not the way they want you to think.
There was a mega continent. And the reason they seem to match is that’s where it split down the middle. The Atlantic seabed is where it blew out. I mean Empire State Building size chunks. That’s where the asteroid belt came from. It’s an anomaly in space. They aren’t everywhere. Not in a sphere but a disc. As the earth turned and this stuff blows out it’s also traveling through space. And we keep running back through the debris. That’s where the water came from, subterranean. And the rocks-asteroids and the comets. That’s why when they test comets it’s the same stuff as in earth. Cuz that’s where it came from.
And the earth sucked in directly opposite and the Pacific holds the run off. And why we have the ring of fire. Makes sense.
I remember in school it was gospel from the experts that human hunting caused extinction of the megafaun. Even as a child, this idea was suspect. All you had to consider was, what about the African large animals that still exist? Weren't they hunted as well? Why were the extinctions regional, animals mainly disappeared from North America and to a lesser degree Europe and Asia?
Exactly. What I was thinking. How come to this day the megafauna in Africa hasn’t been wiped out? They have a answer for that, they had a brainstorming session to come up with a comeback for when people with half a brain question their narrative. Also. How dare anyone question the story they are making up on the spot as to what it all means. Some people believe every word that comes out of their mouths as archaeological fact. They probably watch CNN nightly also so they are used to being lied to and not having any idea. Sad state of affairs.

They discovered a human bottle neck around 15-12kyrs ago where the scientists believe the total human population was reduced to about 5 to 50k individuals and were from Kenya Africa.
The amount of water injected into the atmosphere from a Greenland glacial impact would have it's effect as well. The ice sheet would have reduced the size of the bedrock crater too.
As we learn more about CME and solar outbursts, we realize that it is very difficult to distinguish them from impact events, and they may even accompany one another with high-level events.
Alan Land
In my opinion,
A Solar Outburst Event, (seeming to be a cyclical event. of approximately 12,000 years. Half a “Great Year” )
best matches the mythology, geology and historical climate data.
A pattern of cyclical catastrophic, climate events, . Cosmic impact, is not a cyclical event.
All the impact glass, nano diamonds, and vitrification, are also explained with such an event. As well, as the rapid melting of ice sheets..
The petroglyphs of plasma formations, recorded what ancients saw in the sky .. a worldwide phenomena, suggestive of shared experiences.
Formations of plasma in the sky, seen near the equator are only possible with an extremely weakened magnetosphere.
Not the result of a comet strike .
Solar outburst, seems to be the Catalyst and accompanied by a weakening of the Magnetosphere. Allowing Incoming radiation, essentially heating, the Earths Core. Magma rises, climate chaos, and earthquakes, the result.
It is also possible, that this could be a catalyst for magnetic Pole reversals.
Just like we are experiencing now.

Most large impactors break apart into multiple fragments prior to impact. There was also an ice sheet over 1 mile thick at the site(s) of impact. This is conveniently not mentioned in the impact rebuttal. An impactor, or impactors, could have had massive effects on the planet without leaving a lot of physical evidence or minimal evidence such as a crater in Greenland that appears too small. Unless, of course, you consider the total diameter of the original impact crater in the 1+ mile thick ice sheet may well have been 2-3 times the diameter of the crater as observed today.

Solar Micro Nova. Look at the isotopes in the data that can only come from a nova. And with the recent discovery that these cannot escape the ejected shell in a nova, the isotopes MUST have come from close by. That is, our sun. And it couldn't have been a bigger nova or we wouldn't be here.
The statistical argument is incorrect in that it is based on 'known' comets not all comets. Also even a low probability events can and often do occur.
Besides the fact that it was an asteroid based on the Pt/Ir layer.
An event cannot both be "low probability" and "often occur."

I think the presence of hexagonal diamonds is a dead giveaway of an impact event. They where fond bothat the Clovis site in Tennessee or Kentucky and in Greenland. They only form massive impacts.
comprehensive, Well done.
@ 25:57 In truth there are no "other directions". The amount of energy needed to melt the humongous amount of ice (note that the two YD meltwater surges raised the world's oceans a total of 400 feet) had to have come from an extraterrestrial source. The onset of the Younger Dryas heating events were simply too sudden for more geologic processes to be responsible.
We also have to remember that the YD events were traumatic in other ways besides mere climate change. Large numbers of megafauna species died off, and many of the siblings of these same species are quite well-adapted to our own relatively warm climate. The conclusion has to be that it wasn't the climactic changes themselves that killed off all these species, it was other, as yet unidentified trauma also associated with the YD events that killed off the megafauna and the Clovis culture. Large scale fires and floods are two among many such possibilities.
It is quite likely that the extraterrestrial body that impacted the earth broke up before entering the earth's atmosphere, much like Comet Shoemaker-Levy 9 did in 1992 before it impacted Jupiter in 1994. Much of it must have either exploded over the Arctic ice cap and released large amounts of heat generated by friction with our atmosphere (like the Tunguska 1908 object) or impacted the ice cap in various locations, including the impact craters we can see on Greenland and possibly British Columbia.
Claiming that an event is very low probability is not the same as claiming that it is impossible. Strange, low-probability events do happen. People do win the lottery. They also get struck by lightening. Both are very low probability events. It's also possible that we simply don't know how probable such an impact event might be because our astronomers aren't able to see most such objects. One thing's for certain, our near neighbor the moon is covered with many impact craters, so we do know that impact events do occur with some frequency in our region of space.
If incoming asteroids carry a large electrical charge differential from that of Earth, then there will be a massive electrical discharge shattering the asteroid as it nears impact. This phenomenon may indicate that the lack of craters does not necessarily indicate a localized destructive event. The Dragonstorm Project - sites.google.com/site/dragonstormproject/Home hypothesizes a fragmented asteroid hosing a stream of high temperature electrical plasma discharge from central Mexico to the Great Lakes, like a welding arc melting the tops off mountains and leaving large splatter patterns in the landforms of the Great Lakes region.

All one needs do is calculate the amount of energy it would take to melt 18*106 km³ of ice and understand that the answer is only for the Laurentide ice sheet. Four of the five northern ice sheets melted within a few hundred years at most. Our sun cannot put that amount of energy onto the surface, even with a coronal mass ejection.
Yet the Greenland ice sheet didn't melt along with the other four? Given the trajectory shown by the Carolina Bays riddling the east coast of the U.S.A. and the basins on the North Slope, these bodies came in at a relatively shallow angle. That means they would have traveled in an easterly direction through the atmosphere for a short time prior to impact. In the Tunguska event, it was shown that ground temperatures directly under the trajectory of that body reached ten thousand degrees celcius. That would have melted almost all of the Cascadia sheet and most of the Laurentide, as well as pooling the water quickly enough to create the Yakima floods. There were more than likely a few chunks that landed above Europe and Asia on that side of the Northern Hemisphere. Google Earth zoomed out over North America will immediately show not only large circular bays along the northern shores, but monsterous water flow lines all along the southern ice limit. Both sheets melted almost immediately and flooded the entire continent, washing anything on the surface right out to sea. Probably why we dont' find the bones of the billions of megafauna that died. Though they do dredge them off the North Sea floor.
@@TheDeadlyDan Actually you don't need to account for all the ice melting in one go. The likely hood is that the ice was already extremely unstable with massive glacial lakes containing billions gallons of fresh water. All we need is an impactor or impactors large enough to melt the ice dams and there you have your flood. I would say that this theory is pretty much in its ascendency now. Some mainstream will argue against but probably only the ones that don't like actual science. For certain sure, the, the humans ate all the megafauna theory is preposterous.
Very informative synthesis of the science regarding this controversy.
Discussion completely ignores the Carolina Bays mystery as well as the fact that what ever the cause there was a dramatic extinction of fauna immediately after the event! Possibility a combination of occurrences, the early warming starting to impact the ocean conveyer flow and a impact on the North American ice sheet exacerbating the final result.
To have the famous wooly mammoth to freeze with food still in its mouth would it not seem likely a solar flare hit the ice pack causing an instant flood and the open vacuum of space following the flare allow the coldness of space to instantly freeze afterwards?
Evidence looks like it suffocated to death first. Then froze solid in hours still with the summer flowers. Have wondered on the cause of death of The Beresovka Mammoth. And whether it was that something punctured a hole in the atmosphere somehow leading leading to the coldness of space rushing in. Certainly have not heard any explanations as to what may have caused its death and preservation so quickly. They found another Mammoth, with its body in one position and its feet in another, looking like it was completely blown off its feet, by a shockwave?
Damn!, this shit's heavy. I thought this was a episode of the flintstones that I hadn't seen yet...🤕
I am an expert on the subject since I just typed it in on wikipedia to see what the term meant and my ruling is the impact/s hypothesis is right on especially with carolina bays and other evidence. Carolina bays marks were likely from ice chunks and the elliptical shapes point to the general area up above or near great lakes northern area. Randal Carlson got lucky in his guesses.
More bong hits!
Carolina Bays and similar impact sites in Alaska = impacts onto ice sheet around Hudson Bay and great lake area
There is evidence of massive flash flooding in the state of Washington. I have a crappy memory so I can not tell you the name of the Geology Professor nor the college he teaches at. But he has been trying to get the point across for years. The state has a lot of volcanic activity. Massive ancient lava beds. In one region there layers of sediment have been cut through down to the ancient lava beds. On each side the edges are sharp and very steep. If you find his UA-cam site he always uses a chalkboard and he is quite tall. Thinning hair. Because of Covid he did start using a marker board and videoing from his backyard.
As far as the impact hypothesis. After scientists watched a broken up comet hit Uranus (I think that was the planet) in a line of multiple impacts some proponents of that hypothesis started thinking multiple impacts to the ice sheets in the Northern Hemisphere could melt a lot of it but not necessarily all penetrate them deep enough to leave a crater. Hiawatha crater may be only part of the impact event or a separate impact event.
They have been trying to figure out what caused the sudden spike in temperature just before the Younger Dryas for a long time. One of the things they use against an impact event has always been the lack of a crater big enough. Again, if it was multiple impacts across a large area and into ice sheets about 2 miles thick the smaller bits might not leave any craters. Parts may have hit in the Northern Pacific and Atalanta as well. But nix the multiple impact hypothesis and what are they left with? A huge solar flare, changed in the planets tilt for whatever reason, and/or massive volcanic activity. We can’t, as far as I have heard, chart ancient solar flare activity. The Earth’s axis does change but that has not been known to cause heat intense enough to leave behind ash in such a thick layer. I have not heard that they have found, yet, volcanic activity from the time period that could have caused the ice melt they know happened before the refreeze. Because of ocean levels since only fairly recently have they realized people likely walked into Australia and Britain and that there didn’t use to be much water where the Mediterranean is. They did not know there was a Super Volcano under Yellowstone National Park and it had left a trail as the Continent drifted ever so slowly across the hot spot. Nor that a Super Volcano had blown in Arizona. Or the crater in the Gulf next to the Yucatán Peninsula that was likely made by a really big impact that caused a global bear extinction event and wiped out the dinosaurs. It is good to critique theories. But to say not possible until actual proof of what caused the sudden massive melt that raised ocean levels by 250-500 feet (likely the reason for the ancient flood stories around the globe), left that significant dark layer, and the extinction of many land animals and plants around the globe, I think is wrong.
Nick Zentner
A very scientific approach!!!
Very nice disputation.
10:00 Makes sense to me that there was a major flooding event that happened ca. 12,800 years ago, disrupting the gulf stream, the world cools, glaciers build up again and around 8,00-9,000 years ago glaciers advance, pushing previous evidence for the flood out to sea.
How do you explain in the tektite the radioactive isotopes and fusion tracks.
I think Firestone's 2007 paper (revisited Sweatman 2021) needs the credit for reporting its findings on the impact theory hypothesis
Good job guys. The only thing that could have caused the younger dryas was an extraterrestrial event. The devastation left in the Washington state scablands can only be explained by this horrifying conclusion. By horrifying I mean the fact that this flies in the face of the dominant paradigm that is so beloved by orthodox gradualist lemmings. It takes a generation for old false theories to die and it will only happen with this kind of vigorous debate which can finally bring out the truth. Thank you all for doing this. You all are awesome.
The Channeled Scablands were formed by Glacial Lake outbursts not an impact. Nothing in the Channeled Scablands ties it to an impact. Nothing. It's not even dated to the right time period.
The Scablands have been formed by many glacial/interglacial floods - six in just the last 500,000 years.
@@bobbyt9431 Randall Carlson misinformation is just out of control isn't it?
Freaking drives me crazy so many buy into this man that has been proven wrong time and time again.
Before the Holocene the average temperature was lower til the younga Dryas THEN they spiked indicating massive melting THEN the temps dropped for over a 1000 years THEN something happend to drive the temps far higher than what they where BEFORE THE YD and then the earth gaind 400 feet of sea water AND THE average temps are now FAR HIGHER than they where before the YD what ever hapend to earth ALSO affected the solar system
I think cosmic environnement changes as the solar system travels the galaxy is most likely a good possibility. Cosmic dust or cosmic rays changes.
unfortunately, the class has ignored publicly-available evidence of solar-caused massive cooling of the earth at that time. The evidence is from analysis of lunar rocks brought back to earth during the Apollo missions to the moon 50 years ago. These rocks were tested and found to contain glasses containing internal x ray tracks created by solar super flares or even a micro nova from that same era. And the sun, as we know, is much more capable of such powerful events, that could have caused large scale radiative dimming of the earths surface.
The Diehold foundation discusses this in detail based his findings of the Clock cycle of 12,068 years..
I'm by no means a scientist, but if there were significant changes in solar radiation at that time, wouldn't there be evidence all over the planet rather than just North America? I'm just speculating here - as I said, I'm not an expert at all.

Ground Zero - Hudson Bay. Dec 17 2020.
Is the Hudson's Bay the impact/blast crater that started the deluge which began 12,000 years ago?
What are the pieces I've put together?
Lots of pieces, iron fragments of an asteroid have been found, the last chunk which was found at the 12,000 mark and had been tested to 12,000 years BCE. Over the past hundred years people thought they were iron meteorites, or asteroids. Well, there is a problem with that, there are no craters to verify that fact, and if an asteroid hit the earth it would disintegrate. Most piece of space rocks are part of the meteorite after it explodes in the air.
So why is there so many pieces of iron asteroid found? The asteroid breaking apart so close to the surface, would have lead to a number of possible bursts once fragments hit the ice.
Strange damage to the ancient structures built before 12,000 BCE. Several of these structures have significant damage done at the tops of the buildings which are on the mountains; pre-Aztec, as one archeologist stated looks like a quasar or a magnetic pulse hit it all at the same time. It is true of the damage, these structures still can not be repeated by us to this day. We do not have that power to damage some of the structures noted in the presentations. Both in the middle east and in Peru. The damage to the structures in Peru is north to south, the structures in the middle east is west to east. Earthquake proof buildings.
Russian asteroid, where 200 people were injured due to flying glass after the shock wave from the asteroid exploded, taking 90 seconds to reach the victims. A huge blast at some considerable distance. Why couldn't the damage be more rational like a blast from an asteroid, instead of some alien ray gun?
We have to look at the Gulf of Mexico, confirmed impact which wiped out the dinosaurs, the crater is there, we know it, it is a fact.
This time, when the asteroid went to make an impact, it hit the ice and exploded where the Hudson's Bay is today, sending fragments all over central US. The blast wave, rapid heat, fast rising oceans where cities are still covered under the ocean, and the deluge events. The ice was vaporized and saturated the atmosphere. It took 2000 years from ice age to something of what we have today. 10000 BCE., humans had to start all over again. Our Ancestors before that time lived for 1.2 million years.
Theory of impact is in place and seems to be 4 crater bursts, Iron deposits? less gravity. Funding for the Younger Dryas Impact Theory was discontinued because the impact site could not be determined. All the enchanters, professors, Archeologists, Anthropologists, Geologists, and all the magicians of the world could not find the blast site in North America, When there has always been a blast field with 4 craters, which make up the Hudson's Bay.
Good job.
so if an impact happened in Greenland thru an icesheet. Besides the instant change to steam and blow up thru the atmosphere. the resulting shock wave would shatter the ice sheet that would rain down on the open land covering all that lived. The resulting down draft after the first blast up would bring extreme cold down in areas which could be the reason we find flash frozen mammoths buried.
You may want to include the fact that Clovis points have only been found BELOW the Black Mat layer.
Also, and impact on the ice sheets would result in huge amounts of melting very quickly - also producing freshwater infusion into the northern oceans. Impacts on the ice sheet directly would mute any surface craters, leaving little evidence. Thus, glacial outburst flooding and the impact hypothesis aren't competing, they are complimentary. It is difficult to imagine the energy required for that level of melting in such a short timeframe without invoking one or more impactors on the ice sheets themselves. An extended rainout would exacerbate this effect.
Furthermore, evidence of massive flooding can be found all the way from the channel scablands of WA to the finger lakes of NY. The Missouri and Mississippi rivers are evidence on their own. These are 'misfit rivers.' Meaning that the size of the river basin (bluff to bluff) is much too large to have been caused by today's typical flow rates, regardless of the time allowed for that flow to do so.
These two theories need each other. Good work presenting both sides of the argument. Well done.
We need a planetary defensive initiative to deal with comets and metiors
Not gonna say it was Aliens 👽. But. It was aliens.
If anyone thinks Volcanic processes can't produce and distribute globally, nanodiamonds, platinum, iridium, shocked quartz etc, they weren't paying attention back in January when Hunga Tonga huapai did just that. We are still experiencing the purple sunsets eight months later.
Imagine that one times 100.
That's a Supervolcano like the one that left Hiawatha.
The release of magma stored chemical energy equivalent to about 1000 GIGATONS of TNT, in one or two seconds.
A high volatiles magma chamber like a supercritical boiler over ten km in diameter exploding at supersonic speed.
The Tonga example was just eight cubic km of magma. It got ejected as a 3000C vapour of liquid and gaseous ionised rock at Mach 5, and 10s of thousands of lighting strikes per second burned through the Five hundred km wide umbrella for an hour.
What do you think 1000+ cubic km of magma created in the tight pressure injection of water Subglacial continental regime detonating would do by comparison?
Physical processes guarantee that ice sheet collapses are neither gradual or boring.
Is anyone have any information on the older wetas?
Looking at the chart, the temperature start to drop way earlier before that, gradually.
A very concise and objective analysis, thank you. There are many curiosities about this event in our recent history that are difficult to ascertain, short of the obvious fact that something catastrophic happened. Silt and Bone washed up against the mountain ranges of North and South America, megafauna completely wiped out of virtually all Western continents, leaving only Africa and parts of India least affected. Looking at what we know, comets tend to break up before impact, so a smaller crater somewhere does not necessarily mean anything if larger pieces slammed into the thick ice sheets, leaving no trace, flash melting trillions of gallons of fresh water and setting fire to everything else.
The only humans that survive an event so tragic are tribal societies, currently living off the land and politicians. Personally I believe that a highly advanced global civilization existed before that time, very different from ourselves, yet possibly even more advanced than us. The original human foundation, passed down to us through legend and myth. Even our Christian myth of Lucifer, the morning star, "who's countenance outshined the Sun" is a very accurate description of what a massive ball of ice and rock would look like moments before impact.
Indeed future humans looking back 12,000 years from now would be challenged to find much remaining besides plastic melted into that black mat layer. Everything would be scrubbed away by floods and fire and glaciers, volcanic turmoil and possibly war. Knowing their world was about to end very likely could have ended up with rival powers at each other's throats as legend has it. Punished by God for their selfishness.
Few people really realize what an impact of that magnitude would touch off across the globe, not just biomass burning and flash melting of two mile high glaciers, but major geologic instability, i.e. earthquakes, and global volcanic activity. I mean the Fukushima earthquake alone shifted the Earth's axis by 6.5 inches. A blip on the magnitude of scale...
My question is what is the possibility of the turning point caused by major solar activity, CMEs, possibly even micro nova, and magnetic reversal creating even more catastrophe than a large impact, since the evidence is so scarce I would like to know your thoughts on this?
Thank you
I think this was a good debate. I found that proponents Against the YDIH relied on evidences found by creditable people that had questionable sampling techniques.
What was the sun doing at this time? Isnt there a new paper released about a "micro-nova"?
What it wasn’t a comet but a solar flare caused by a nova event of the sun? 12000 year cycle is here
Solar micronova plus possible CME impactor... We're due for another one of these days - 13.000 year cycle.
What about the scabbard floodplains and the Carolina bays..craters from after impacts of ice.
Impact theory is not opposed to a glacial flooding. The heat from a cosmic impact is what is required to melt the glaciers. Plus it explains the black mat. This is a false dichotomy. Fire - flood - freeze. Check out the review of papers on the YD by Martin Sweatman.
They are not soccer balls
They are footballs.
...it's awesome...if it was a catastrophic event that caused the YD...wouldn't we need another catastrophic event to cause the one that everyone says we are headed for? they are cyclic maybe the cycle attracts catastrophe...
Interesting and plausible. But there is a vast literature on this subject relating the Younger Dryas to glacial Lake Agassiz. So I also doubt this research will go far. Well done and well presented.

Well, something caused the Younger Dryas! If a strong logical explanation (with some supporting evidence), is argued against, then you better have your own hypothesis as to what caused it. So far, opponents of the extra-terrestrial explanation have not countered with anything substantial. This makes me very suspicious that they are wrong in their objections and in fact are holding back the probable explanation of the Younger Dryas.
They are hiding the Alpha and Omega. A plasma discharge glassing Atacama and recorded at Nazca (lines) by removal of the iron spherules that were FUSED from silicates.

Thanks for the plug.
The Laurentide Ice Sheet was over a mile thick! Between multiple impacts on the Ice Sheet and atmospheric explosion from a break-up of the impacter, there wouldn't be terrestrial craters. The Carolina Bays illustrate this impact on the Ice Sheet. The heating, shockwaves, and flooding from melted ice as well as torrential rain from the vaporized ice would have been sufficient to affect weather patterns as well as directly and indirectly cause the mass extinction of the megafauna. Impacts in the Hudson Bay and Great Lakes areas would have been sufficient to cause this scenario. Greenland impact is too old as the ice covering it is older than Younger Drias. The impacts on North American Ice could have sent enough fresh water into the North Atlantic to disrupt ocean currents as well. IMO
The heating of impact would be negligible but bursting an ice dam releasing a lake the size of Ontario and deep as a sea would do a lot.
If comets are mostly "dirty ice", how would one survive the incredible heat experienced, as it enters and travels thru earth's atmosphere?
Forget the crap you see on TV, a comet is moving at roughly 300km per second, and enough of it can and will survive the death dive into a planets atmosphere to be able to cause catastrophic damage. Most explode above the surface though, composition and size really matter.

The large cooling of some substantial part of the northern hemisphere (-8 degrees mentioned here for Greenland) combined with the tiny cooling of only -0.16 degrees global average per the huge 24k year global multi-proxy analysis (a synthesis of a few dozen separate proxy analyses all around Earth that took scientists 7 years to do) could only have been caused by a sudden stop, or big reduction in how far north it goes, of the powerful Atlantic current because nothing else would have cooled a few percent region of Earth in the Atlantic region and not cooled anywhere else. Volcano or asteroid impact global dimming wouldn't do that. An asteroid impact might well have caused the current to stop or change. What happens is that less heat gets carried north (it's 6 petawatts right now) causing north to cool and the tropics, maybe south too, to warm but because most land is in the north, most ocean in the south, the land cools more because ocean mixes a bit of its huge thermal capacity, so overall there can be global cooling even without Earth getting heated less than before. However, what can happen if this switch of heat transfer warms the north less is that there can be more ice & snow because, as with the thing just mentioned, most land is in the north, most ocean in the south. Since ice & snow are reflective there could become genuine GLOBAL cooling due to more sunshine reflected.

Micro nova from our sun
Zamora et al have proposed an impact on the southern edge of the Laurentide ice sheet, which caused a rain of ice chunks to fall up to about 1500 km away, causing the so-called Carolina Bays, with similar features in other areas such as the Gulf of Mexico and Nebraska, (en.m.wikipedia.org/wiki/Carolina_bays) as well as a release of ice and melt water into the north, and a distribution of water in the stratosphere that would have caused global cooling for several years, and associated rains . Associated impacts in other areas such as Argentina at the same or nearby time would have caused global fires.
OTOH, the presenter of Ancient Architects on UA-cam notes that the dip in temperature was not all that sudden, and matched several previous episodes.
Related - the Scablands and Dry Falls region of Washington State does provide evidence of extremely large releases of water on numerous occasions, with flows hundreds of times greater than any known river, as a result of melt water lakes breaching dams in the edge of the ice sheet. These releases were hundreds of feet deep and miles wide. Just the backflows filled the Willamette Valley of Oregon over 400 feet deep, and the flows also caused "ripples" in sandbags in the Columbia River with periods of several hundred feet and depths up to 100 feet.

If you are going to argue the pros and cons of The Younger Dryas Impact Event, don't do it with students who are not familiar with the exhaustive evidence that has been researched and submitted. Especially, don't make suppositions that are completely false about the the claims of the Comet Research Group. This is not an educational debate. It's a bunch of opinions based on limited knowledge.
A third hypothesis for the cause of the Younger Dryas event can be found with the Farsight Institute remote viewers who say humans accidently caused an explosion so large it devastated the entire world. Apparently a civilization existed even more advanced than our own but ended up having technology get the better of them. As a consequence to this catastrophe, their island continent sank and sent the oceans across the lands in a succession of mega tsunamis from every direction. There would've been drastic changes to ocean currents and probably worldwide storms until it all resettled. This "hypothesis" actually makes sense to the evidence seen and should be considered by academia . . . but guess what? Remote viewing is just conspiracy nut pseudoscience and cannot possibly work. Anyway . . . our "known" history has not seen a large scale landmass and oceans, into motion event but they do occur and might even be our biggest natural threat. There's virtually no size limit to earthquakes and the their subsequent "mega" tsunamis but we don't hear much about it. Psychics are saying they see California cracking into the ocean in the near future! I choose truth for myself, it's so much more interesting!
Thus, while we can give the class an "A" for their production of this high quality video, we must mark them down for "not" uncovering that the Younger Dryas has been marked in time, as occurring repeatedly, every 12.6 thousand years, or so. That the event repeats is the most significant "fact". Almost as important is the fact that the Apollo Astronauts found massive evidence on the moon over 50 years ago that the event causing the Younger Dryas was a solar micronova. Nor has the professor of this class seen fit to help all of us by producing the links to: Dr. Anthony Perat, Dr. Robert Shock, the Diehold Foundation, BenDavidson's SuspiciousObservers.org, Dr. Wallace Thornhill, Dr. Donald Scott of TheThunderboltsProject, Dr. Michael Claridge of The Safire Project... and so on, for leading all of us to the significance of all this. Traditional academia, it seems, is incapable of actually "providing" useful education in the solutions to real problems. So we might also include Google in our thanks, for keeping this forum extant.
Of most benefit to all of us is the Safire Project, which has demonstrated experimentally here on earth how to create sustainable fusion power. It could lead our descendents out of darkness the next time the sun throws a conniption.

Thanks to geologists, we think that all living things on our planet have the most to fear from an asteroid impact. But when we look at the many horizontal layers that we find everywhere on our planet, we clearly see the effect of a repeating cataclysm. These disasters are mentioned in ancient books like the Mahabharata from India and the Popol Vuh from the Maya. They tell us about a cycle of seven disasters. Certainly, a cycle of regularly recurring, thus predictable but inescapable global disasters cannot be caused by asteroid impacts. The only possible cause is another celestial body, a planet, orbiting our sun in an eccentric orbit. Then it is close to the sun for a short period and after the crossing at a very high speed it disappears into the universe for a long time. Planet 9 exists, but it seems to be invisible. These disasters create a terrible natural cataclysm with much flooding and a cycle of civilizations. To learn much more about the recurring flood cycle, the re-creation of civilizations and its timeline and ancient high technology, read the e-book: "Planet 9 = Nibiru". This book answers many of your questions about our past. It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9
Because with few to none scientific basis regular people are easily fooled by snake oil salesmen like Al Gore. Science isn't established nor consensual so you gotta listen to both sides and that side is not only not shared by geologists, and you didn't even checked what the geologists say. You have no idea what you are talking about!

Nice thoughts but you have missed looking at a Mini Nova of the Sun where all these glassy carbon spherules, the rounded magnetic particles, the nano diamonds and the iridium spikes will all be found - Look at the Safire project's latest results. Wildfires would result and probably widespread glacial melting so all your observations would be correct under a mini nova basis - which is also a repeating phenomena.
The melting? Plasma
At approximately t=5 minutes you speak of "theory 2, a bolide impact" as an alternative to "theory one, a stop of the thermohaline circulation because of meltwater dumped into the ocean". That logic is flawed, those theories are not necessarily alternatives, theory 2 is one of the possible causes for the event in theory 1. Both may have combined.
Yes it's possible that meteor impact at what is now the south tip of Lake Michigan burst a huge ice dam that was holding back Lake Agassiz causing a flood of fresh water into the Atlantic.
