Exploring abrupt climate change induced by comets and asteroids during human history

Comet Research Group member Marc Young presents at Flinders U

Reveals deep flaws of Surovell et al. 2009; outlines research program

In 2009 the newly proposed Younger Dryas Impact Hypothesis was knee capped by Surovell et al. To this day, despite a comprehensive 2012 expose of Todd Surovell’s flaws, his premature rejection of the YD impact is uncritically cited by opponents of the evidence and remains the final word in many closed minds.

It remains a grudging task of the Comet Research Group to periodically refute his mistaken study and another effort is well underway Down Under by the #1 Tusk Buddy Marc Young. Marc is an honors student pursuing an Archaeology PhD at Flinders University in Adelaide, Australia. Since his undergrad years, Marc and I have corresponded frequently on all matter’s YDIH.

From social media — where we bat back the critics — to more fruitful efforts such as Marc’s creation and establishment of the The Bib, he has become indispensable to changing the paradigm

Marc gave a stunning presentation at Flinders this week to his colleagues. It was a milestone for “2nd generation” CRG research, and a don’t miss for anyone interested — or ignorant — of the globe chilling human, earth and animal catastrophe ~12,879 years ago.

Marc starts by giving an insightful and succinct explanation of the YD impact evidence — which is no easy task. And finishes with a research program which will set Surovell et al. on their back heel for good.

Enjoy.

  1. The first few minutes are very quiet as the talk has not started yet. Try fast-forwarding a bit.

  2. Congratulations on a magnificent presentation Marc …… The dating of the 1930 Curuca River triple airburst is erroneous however …It occurred on the 13 August – not the 25th
    and I have discussed the implications of the Perseid stream peak – or a recurrent clump of the mystery Bonilla swarm sightings of 1883 – here previously ….George it may interest you Marc and Tusk aficionados that speculative airburst residue has been located at a site in the Atacama Desert bookending the Younger Dryas circa 12000 BP …. The 12900 Younger Dryas onset was probably caused by hundreds if not thousands of Tunguska class airibursts and a few surface impacts over a hypothetical timeframe of a few hours to several decades .. Further examination of that timeframe is crucial as it suggests a series of cometary debris bombardments across the 1200 year cooling period. notwithstanding the finer dust loading of the atmosphere as yet untraceable until an exhaustive analysis of the Arctic and Antarctic ice cores is conducted …. Investigating the Greenland Camp Century cores in 1983 using a neutron activation analysis technique, Paul la Violette detected unusual elevations of what looks to be cometary dust in the period 19700 – 14200 BP which tantalisingly precedes the Younger Dryas yet falls within the proposed timescale of the entry and gradual disintegration of the Taurid progenitor comet in the inner solar system 30 000 – 20 000 years ago. To quote [ this is worth revisiting ] Clube and Napiers passage from ‘The Cosmic Winter pp 269 -70 :

    ” High iridium levels were found in all the samples examined ………. The levels correspond to deposition rates 10 to 60 times greater than those of the present day . La Violette found also that the dust had a very unusual chemical composition ; and at particular levels in the ice , the overabundances of several elements jumped by over 27 000 times and silver by over 200 times .It is very unlikely this is ordinary meteoritic material since there appeared to be particles hundreds of times richer in tin , antimony , silver and gold than ordinary meteorites. It is very unlikely too that this material came from Earth : for example the tin is over 100,000 times more concentrated than the ordinary material of the Earths crust .La Violette pointed out that ” If this material is of extraterrestrial origin ,its source must be different from that of the majority of meteoritic material ”

    The moss extractions and at least one Tunguska impact site peat bog study have yielded geo -chemical anomalies not inconsistent with the La Violette study suggesting the Tunguska bolide was indeed a Taurid meteor from the same gigantic comet that shed massive quantitities of dust deposited in the late Pleistocene ice
    Also interesting is the Franzen and Cropp Cobalt / REE index manifesting a persistent “high broad peak ..from c 10 000 BP to the bottommost layers at 14 000 BP” There is no standout spike [ only a plateau ] approximate to the Younger Dryas yet the authors emphasize the 8000 – 14000 BP graph is based on only a few mires in Ireland and Tierra del Feugo ” ..In other words it is incomplete compared to the middle to late Holocene series comprising over a dozen mire locations …….The sloping flickering timescale of the Cobalt /REE index is more or less what one would expect to see from a progressively disintegrating super – comet losing mass over millennia with the peaks in the sequence best explained as fragmentation events and nodal intersections [ not all of them Taurid Complex streams understandably ] with the Earths ecliptic plane ……..It could essentially be interpreted as a Taurid Complex dissolution or attrition record as the finer micron particles disperse into the Zodiacal Cloud and deep space and less material in the sub Jovian complex is left to deposit on Earth ..

  3. Late Younger Dryas [ 12 300 – 12 000 BP ] southern hemisphere airburst proxy evidence has been discovered in the Chilean Atacama region

    “Widespread Glasses Generated by Cometary Fireballs During the Late Pleistocene in the Atacama Desert Chile , Schultz ; Harris et al , Geology [2022 ]50 [2] :205-209

  4. Marc Young’s point about the glacial flow from one crater to the Hiawatha crater can be tested & proved/disproved with a Greenland expedition that drills in and between the two craters, with enough samples.

    That is a ‘money solvable problem.’

    That is a nice bit ‘o science Mr. Young did there.

  5. The Hiawatha Crater is not really that relevant now that the Younger Dryas Impact Hypothesis is proven

  6. I misspoke a couple of times. I said plummet when I meant rise, I said 30,000km/s when it’s either 30,000 m/s or 30 km/s.

    Those atacama airbursts are strong evidence, would have included but didn’t have time, maybe could have replaced Hiawatha with them.

    I am making an extended youtube version with a lot of extra content but it won’t be out until the end of the year.

  7. @Stuart Hamish, do you happen to know the work by LaViolette that Clube and Napier are citing there? That would be great to include in my thesis.

    Marc

  8. ” Those atacama airbursts are strong evidence , would have included but didnt have time ” ……

    “Marc Young did briefly allude to them…

    I wish Marc Young well with his archaeology Phd …..The sneering prejudice toward Holocene asteroid and cometary impacts affecting human societies I encountered when taking archaeology electives at university was something I wont forget …I based two of my essays on Mike Baillies ” Exodus to Arthur ” and the 1998 Natural Catastrophes During Bronze Age Civilizations Cambridge Conferences compendium .. I recall receiving some “stern admonishment on such “fringe” theories from a few smug arrogant politically correct academics in the archaeology department ….I dont think it went down well when I later pointed out that an obsequious department head who co authored a disgraceful contribution to a vicious vengeful hatchet job [ the Grand Inquisitor who edited the book was busted for plagiarism and not sacked ,, Not a squeak from the sanctimonious archaeology department either ….”repressive tolerance” and all that ] attacking an Australian historian – now editor of Quadrant magazine – who controversially exposed the research fraud and exaggerations of left wing aboriginal historians, permitted [ or solicited ] the deep time Vedic creationist Michael Cremo to write an essay in a compilation he edited .. Rather embarrassing I would imagine …….. Even Graham Hancock cold shouldered Cremo . I hope the archaeology department head is reading this……..To paraphrase Orwells ‘Animal Farm ‘ I suppose some ‘fringe’ ideas are more acceptable than others in various archaeology departments … Woke ideology certainly is

    Do you know who I am referring to Marc ?… Have to tread carefully do you ? All the best and I hope you do not have to overcome too many barriers ..There are some nasty horrible intolerant people in the field of archaeology

  9. George , Marc , La Violette was opposed to the hypothesis of cometary or asteroid vectors as ” the source of the iridium in the Late Wisconsin stage ice ” predicated on the assumption ” that such events would not be expected to occur frequently enough to account for the observed Ir concentrations . For example dust from the impact of an asteroid or comet would remain airborne for less than a year ” …….

    .Can you detect the flaws in his specious reasoning ? …..Notice La Violette constrained his argument to impacts while eliding amplified shedded dust influx and deposition rates that would be expected as a volatile comet disintegrates or the Earth repeatedly intersects the thicker core of a short period meteor stream …..He also did not take into consideration the variable sizes of asteroid or comet fragments – let alone debris swarms and multiple year bombardment episodes aka Clube and Napier – with his presumptive statement ” dust from the impact of an asteroid or comet would remain airborne for less than a year ” …He has not understood [ or acknowledged if he has ] the ” coherent catastrophism ” paradigm

  10. Goerge Marc et al , the 14000 BP Nickel , Iridium concentration peaks and the Franzen and Cropp Cobalt / REE values – two disparate extraterrestrial element combinations [ ice cores and peat mires ] in two different proxies – match
