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

Ancient airburst over Ohio

Critics split hairs over ~350 AD American catastrophe paper

Background from Smithsonian Magazine
Breakdown from Archeothoughts

Erudite Tusk commentor Stuart Hamish below refers accurately to this Neuheuser and Neuheuser paper responding to Tankersley et al., as “hair splitting.” I’d agree.

Stuart also includes some juicy tidbits about other modern impacts that are worth sharing. Incidentally, I plan to take Stuart up on his suggestion that I post on the obscure but profoundly important Bonilla Event of 1883.

“However the material evidence ……… does not speak for a comet compared to an asteroid….”

So what? That statement right there is the giveaway for “splitting hairs” dissembling on the authors part …..The Ohio Valley Hopewell culture was destroyed either by an air-bursting cosmic object that may have been a random asteroid , an inert comet fragment indistinguishable from an ‘asteroid’ or a chunk that cleaved from a passing active comet An extraterrestrial impact nonetheless …Tankersley et al did not contend the Ohio Valley airburst was ’caused by an airbursting comet entering the Earth’s atmosphere ” [otherwise we would not be here to debate matters] but rather a comet fragment .aka Tunguska …..So Neuheuser ‘s rebuttal incorporates a Straw Man fallacy as well as  “splitting hairs’ ruse …”In sum the claim that human communities ……were at a heightened risk …. by a comet airburst in those centuries is unsubstantiated ”

Not at all. I presented the Franzen and Cropp Cobalt / REE index 300 – 400 AD ‘ H8’ peaks in their peat mire time series [Correlated values much like the 3700 – 3500 BP sequence] as complementary, substantiating evidence for the Tankersely et al Hopewell airburst hypothesis. This data is speculative evidence for one of Clube and Napier’s enhanced risk of bombardment episodes approximate to the time of the Roman Empires unravelling, climatic instability and barbarian incursions.

Neuheuser’s discussion pertaining to Comet IP Halley is essentially meaningless. Three of the worlds most destructive 20th century airbursts occurred close to the peaks of three cometary stream intersections : Tunguska June 1908 [ the Beta Taurids ] the December Rapanui event British Guyana bolide [ the Geminid stream ] and the August 1930 Curuca River triple airburst over the Amazon coinciding with the Perseid shower perigree……It is plausible the August 1930 Curuca River impacts were a recurrent clump of the 1883 ‘Bonilla sighting’s ” – a speculative stream of cometary debris spotted by Mexican astronomers in 1883 that may have missed Earth by a few hundred to a few thousand kilometers if retrospective calculations are correct …..Note the August 1930 Curuca River bolides struck close to the August 12 -13 1883 Bonilla sightings dates and close to the same time in the morning [just after 8.00 am]. Isn’t that intriguing ? ….The disintegrated comet stream telescopically detected in 1883 may not have been related to the Perseid stream progenitor but rather another ‘mystery ‘ relic comet swarm brushing past the Earth approximate to the same date as the Perseids .

    The sub – headline text also requires re -editing : ” Tankersely paper on 1500 AD Hopewell airburst weakly criticized ” ….The hypothesized Hopewell airburst timescale ranges from the 3rd to 4th centuries AD

  2. The ‘Milford Earthwork ” may be a cultural artifact symbolizing the Ohio Valley bolide and its plume as it entered the atmosphere

  3. I do not agree with some of the fanciful ideas discussed in the latter portion of this article George . It is there to be mined for information and in this instance the 1883 WAIS Divide ice core anomalies pertaining to a speculative impact somewhere over the southern ocean in 1883 .. The February 1883 WAIS Divide Antarctic core ammonium signal is the second largest of the 19th century and the black carbon column [absent any record of a massive biomass burning event in the southern hemisphere thus far ] the biggest for the 19th century section of the WAIS Divide core …..There is also a large bromide [ found in higher quantities in seawater ] spike located at February 1883 in the WAIS series …..I am not a chronologist or glaciologist although perhaps it could be asked if there is sufficient irresolution or ‘slop’ in the WAIS Divide core to move the unusual values of the ammonium , BC and Bry elements forward five months or so to early August 1883 … Jonny McAneney [ my quarrels with him and his trustworthiness aside ] or Sigl and others may wish to contribute to this query .. To my knowledge there was no Antarctic base in existence in 1883 if a bolide exploded over the Antarctic or the southern western Pacific that year …The Indonesian volcano Krakatoa erupted in late August of 1883 but that event is almost certainly coincidental https://www.sott.net/article/436823-Krakatoa-And-The-Great-Comet-of-1882-Exploring-The-Real-Engine-of-Climate-Change

    I will take up your offer George … Thanks mate .. I could not see your April emails from my end until weeks after they were sent [ ?] Shall contact you soon when I sort out my ‘issues’

  4. Stuart, you are either an intuitive nut on the scale E.P. Grondine, or you are the most critically insightful sane man on earth. It’s a fine line. In any case, you are my man. I’d love to hear from Jonny, and see you all collaborate some more. It would be fruitful fo sure.

  5. Yes it is a fine line …..One of my favorite books is W.G Sebald’s ‘ The Rings of Saturn “.. The astronomer Mike Bailey [ from memory ] realized the 1935 Rapanui and 1930 Curuca River bolides coincided with comet stream perigrees.. Have you read Mike Davis’s chapter review of Clube and Napiers theories titled ‘ Cosmic Dancers on History’s Stage” in his tome ‘Dead Cities ” ?….

  6. I am skeptical of Chandra W and his colleague Joseph’s extraterrestrial biotic disease hypothesis [ I favor the mass immunosuppression in human populations and terrestrial pathogen “mutagenic pulse ” models ] applied to disease epidemics such as the Black Death and Justinian Plague ..That said , I respect him very much as I do you and you are both eminently more qualified than I …. I have some information for him that he appears not to have spotted as it relates to the 1976 and 1977 influenza outbreaks ….. The interesting thing about the 1977 influenza epidemic thought to have originated in north east Asia , [ there is that crucible again downwind from the Himalayas Chandra and yourself chatted about in the video link ] was the viruses remarkable genetic similarity to the 1918 pathogen . The 77 influenza strain allegedly did not accrue recombinant material at the rate expected if the virus was extant naturally ……It either escaped from a laboratory , emerged from a frozen corpse …….or there is another exotic explanation….. What space event happened in 1975 causing profound atmospheric disturbances that also occurred in 1908 and 1914 in the prelude to the 1918 -20 influenza pandemic George ? [ See Chandra Wickramasinghes and Joseph’s ‘ Diseases From Space ” in the Journal of Cosmology ] …..As I said Im somewhat skeptical although it may be useful …..

  7. George will the circa 350 CE black carbon ammonium and levoglucosan spikes in the NEEM core stratigraphy be more closely analysed for extraterrestrial trace elements ? …..That date looks to be the best candidate for the Ohio Valley airburst residues and one can see that it ‘sits’ in the peak of the 400 – 300 CE cobalt /REE index H8 sequence …Exactly in accordance with the Clube – Napier coherent catastrophist model

  8. I am experiencing irritating ‘obstruction ‘ online once again George so can I request you research Knowledge magazine for the year 1883 [ pertaining to atmospheric disturbances noticed six months before the August eruption of Krakatoa ] The newspaper reports in Trinidad and surrounding islands and Natal South Africa in the southern hemisphere for that same year prior to the eruption may be worth examining too

  9. The Australian newspaper The Herald Sun ” ran a front page story on Chandra’s extraterrestrial bacteria hypothesis in 2001 titled ‘Space Bug’s “

  10. Only quoting George to grandstand yourself is solipsistic narcissism …..Hows that for an insight

  11. If the atmospheric disturbances noticed six months before the late August 188 eruption of Krakatoa in South Africa can be verified George then the February black carbon and ammonium peaks in the WAIS Divide ice core are authentically dated ….The mystery abides as to the cause these elevate values

  12. You have not been called a ‘name” ….Its a condition …..You referred to yourself as if you were a man of magical insights far surpassing ” other people ” …..The epitome of narcissism

  13. Yes I am familiar [ albeit as a late contributor to the Cosmic Tusk ] with your unfortunate circumstances and health problems EP Grondine …..You are not the only one [ Now you may have a better appreciation of solipsism ] . I have incurred injuries, endured malicious false accusations, censorship and a lot more ……Quite a few barricades in my way to resolving them too …. One of my two earliest memories when I was 3 was getting battered by an enraged bull [that escaped from an open gate ] in a sandpit ..If my older brother did not witness it to alert others and a mound of malleable sand was not beneath me as a buffer , it would have killed me instead of just battering me unconscious . Graham Hancock almost died after serious medical complications …[ Andrew Breitbart and his coroner didn’t make it but thats another story ]…I have applauded you and ethnographers such as Bruce Massie previously . Have you ever said a kind word for me ?…..I hope that clarifies things for you ……As for your “strict rules of evidence” and ” realization of an entirely unsuspected factor affecting human societies ” asteroid and comet debris impacts were not ” entirely unsuspected ” as of 1995 ….Clube and Napiers ‘The Cosmic Winter was first published in 1990 and among the raft of quotations presaging the chapter ‘Cataracts of Fire ” was a passage from the book ” The Romance of Reality ” alluding to a cometary dimension .to the
    Black Death and the 14th century climatic turbulence .. Thanks for the prod to read your Cambridge Conference papers …

  14. Serial pest EP Grondine [ or some ‘doppleganger ] is not familiar with a compendium of my research and writings easily viewable and accessible to anyone on this and other websites and blogs …..I wonder why someone advised me not to respond to him
