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

Bang: NatGeo covers new evidence from the Holocene Working Group

You gotta love the Yellow Rectangle. Richard Lovett writes for National Geographic that the The Holocene Working Group (HWG), as ably led by Dallas Abbott of Columbia University’s Lamont-Doherty Earth Observatory, has new work out. [Giant Meteorites Slammed Earth Around AD 500:  Double impact may hvae caused tsunami, global cooling].

It seems the HWG has confirmed the presence of craters of some nature in Australia’s Gulf of Carpentania — just as predicted by the HWG using their ‘chevron’ dunes as pointers. (CT will get a hold of the source publication asap.)

From National Geographic

For years Abbott, of Columbia University’s Lamont-Doherty Earth Observatory, has argued that V-shaped sand dunes along the gulf coast are evidence of atsunami triggered by an impact.

“These dunes are like arrows that point toward their source,” Abbott said. In this case, the dunes converge on a single point in the gulf—the same spot where Abbott found the two sea-surface depressions.

The new work is the latest among several clues linking a major impact event to an episode of global cooling that affected crop harvests from A.D. 536 to 545, Abbott contends.

According to the theory, material thrown high into the atmosphere by the Carpentaria strike probably triggered the cooling, which has been pinpointed in tree-ring data from Asia and Europe.

What’s more, around the same time the Roman Empire was falling apart in Europe, Aborigines in Australia may have witnessed and recorded the double impact, she said.

But wait……it gets better.  Dallas and the gang gain support from an independent researcher of — get this — aboriginal oral histories.   I bet whatever happened would make you drop your Didgeridoo and run for the hills.

The always skeptical and increasingly quoted Mark Boslough of Sandia Lab then weighed in.  Mark seems to have made a single criticism:

We have a pretty good idea about how many there are and what the frequency of impact should be, and the abundances based on [the working group’s claimed
crater count] are orders of magnitude greater than what astronomers observe, Boslough said. It’s pretty hard to imagine where these things could be coming from so that astronomers wouldn’t see them.  Mark Boslough – Sandia National Laboratories
Gee.  I sure hope Mark is right.   If he and “astronomers” are wrong it could mean everyone at any time faces a relative peril from above far greater than anything else we regularly consider as somewhat dangerous.  In fact, if Mark is wrong — and Dallas is right — you are at more danger waking up than you are driving or flying.

  1. It may or may not be a coincidence that there has been identified a 400-500 year periodicity in impact caused tsunamis; this from the later part of the Holocene. This is based upon Dr. Ted Bryant’s assessment of a number of deposits from along the coasts of Australia. The event that Dr. Bryant concentrates upon, is from an alledged impact event that occurred about 1500 AD. It just so happens that not too far away in New Zealand, some palaeotsunami deposits have also been identified (Goff et at). Admittedly, these researchers did not link the New Zealand finds with impact events, at least not as discussed in the article I have. Back to the approximately 500 AD event, a number of other researchers that include Dr. Mike Baillie, have emphasized a number of additional possible signs of an impact event close to this time. Important Greenland Ice Core acidic peaks, and references from various localities of cold associated with crop losses and failures are some of the clues that Dr. Baillie cites. (Baillie). Also, intriguing references, primarily from southern Europe, tell of all manner of references to a much dimmer sun. (Baillie). This was a time that was initially called the European Dark Ages, as presumably the event was first detected by western researchers from Europe. The specific dates for this interval are from the mid 530’s AD to about 542 AD. However this date may well be close enough to Dr. Abbott’s work to be one in the same.

  2. Here’s a hint for Mark: The only way the data makes sense is if you add in hits by comets to hits by asteroids.

  3. Hi Pierson –

    Dea Urquidi has been working for years trying to apply a Velikovsian Saturnian cosmology to the Maya texts, with no clear readings emerging. Which is not surprising, as Velikovsky’s cosmology is well known to be wrong.

    For a better start into Mayan records, see:
    even though it has errors

  4. Hi EP

    I fished a few things from the text

    “… The bulk of this survey will focus on a mega-tsunami event ca. 1150-1050 BCE, which fairly well devastated those living along the coasts of this area. In order, the second part of the survey will cover the peopling of the areas which the impact affected, and describe the lives of those who died in the event. The third part of the survey will cover the preservation of later historical records and folk memories of the catastrophe. The fourth part will set out some of the historical and myth materials which have survived, including also some materials which appear to refer to the earlier Rio Cuarto impact event.

    Sometime between 1150-1050 BCE nearly all of the Atlantic cultures suffered a tremendous setback. In Atlantic North America, the Late Archaic comes to an end, and shell ring cultures pretty much disappear from the Atlantic Coast, while survivors appear to have hanged on in Western Florida.

    In the Caribbean Islands, the early shell cultures come to a stop, as does inter-island trade. Peoples immigrating into the islands a 1,000 years later would find a few technically primitive survivors who told tales of their ancestors surviving a great flood from the east by hiding out in caves.

    Along the Gulf Coast of Central America, there are site discontinuities over a large area, centered around a date of about 1150 BCE.

    There were no victors in these wars between the Mayan city states, except, of course, for the Toltecs. Sometime around 1150 CE the Mexica (Aztec) appeared in the Valley of Mexico, and the Toltec left the area, immigrating en masse to the Yucatan, where they finally established dominance over the Mayan areas, and set up their capitol at Chichen Itza around 1150 CE.” …

    Curiously in many regions of the States of Georgia and Florida, there are many paralell elliptical lagoons with presents the same characteristics of orientation of the Great Serpent Mound and its possible elliptical associated basins, meteor lakes.

    The Great Serpent Mound geoglyph (Lat. 39.025956°, Log. -83.430375°) looks like a tipical prehistoric subject register of a big meteor event, but it could have more informations than believed before.

    The geoglyph seems to indicate the dinamic of the phenomenon, a meteor comming from a long distance from the south (a hole in horizont), passing (about 25 km) close to the prehistoric observer, and following in direction to the northwest for its final explosion (about 60 km). The Great Serpent Mound geoglyph seems to point to some lined elliptical basins.

    The region near Wilmington, Ohio, USA, presents topography and homogeneous draining, but two regions present elliptical basins, and detached among the others. These basins today are dammed. The two regions of the elliptical basins (Lat. 39.530538°, Log. -83.990907°) (Lat. 39.387512°, Log. -83.922224°) are lined up in a straight line.

    Could they be related to same phenomena?

    The elliptical and conical Panela crater on Brazil, and its aligned elliptical field of related structures (>15) should have oringin in a cosmic event in 1234 +/- 210 BC, its estimated age is based on archaeological (C14) data. The possible Serpent event on USA, a cosmic catastrophe in the region of Bahamas, Florida, Georgia and Ohio, based on archaeological data for Serpent Geogliph could have oringing in an event in the year 1070 BC. Despite the uncertainties of dating, the average date 1152 BC for Panela crater and Serpent event is consistent with the proposal by Baillie dated episodes: 540 AD, 44 BC, 207 BC, 1159 BC*, 1628 BC and 2345 BC for a meteoroid stream encounter.

    Could they be able to be part of a same meteors rain, meteoroids coming from the south, could they have the same age?


  5. Hi Pierson –

    A good part of what you quoted there did not come from my work, and was not and is not my analysis. You also seem to have confused BCE and CE dates, and the dating of migrations, and who migrated when, due to what.

    The mentions of paleolagoons and the analysis of Serpent Mound which you have added on to my work are definitely not mine.

    I’m not familiar with the Panela Crater, but with the RC date which you mention, then PERHAPS it could have been caused by another fragment of the impactor which caused the Great Atlantic Impact Mega-Tsunami. That appears to have been a cometary impactor, but 1159 BCE appears a little early for the date of that impact.

    Serpent Mound was built by the Andaste people around 1,000 BCE, radio-carbon date, and later used by the Tchalaga, ancestors of today’s Cherokee and Shawnee.

    The Andaste had recently migrated to that area as a result of the Great Atlanitc Impact Mega-Tsunami. From the records of them we know that their construction of that geoglyph is related to cometary impact.

    My colleague Fletcher Wilson and myself have already published a short pamphlet on it, and we are currently working through Serpent Mound’s alignments.

    Thanks for your note, we will take a look on the ground around Wilmington of the structuress you mention sometime later this year.
    I will keep a special look-out on for signs of discontinuities in the archaeological record of the area around them.

    Bill Romain has another hypothesis for Serpent Mound’s alignment, involving the Milky Way and some constellations.

  6. Hi Pierson –

    Given the pattern of the destruction seen in North America, I doubt if the Panela Impact was part of precisely the same event as the Great Atlantic Impact Mega-Tsunami.

    You may want to check with Dr. Abbott on this, for other impact mega-tsunami from roughly the same period – perhaps she knows of an impact in the Gulf of Mexico.

    Perhaps it was the impact of another fragment at another time during this encounter with Comet Encke’s fragment stream.
