    Joining The Dots

    I have now published my new book, Joining The Dots, which offers a fresh look at the Atlantis mystery. I have addressed the critical questions of when, where and who, using Plato’s own words, tempered with some critical thinking and a modicum of common sense.Read More »

Younger Dryas Impact Hypothesis

The Younger Dryas Impact Hypothesis (YDIH) is based on the claim that around 12,800 years ago the Earth had an encounter with a very large asteroid or comet that broke up in an airburst over North America and of which some fragments possibly hit the ground directly(a).

Many effects have been linked with this event with varying levels of enthusiasm including a suggested association with the demise of Atlantis. Elsewhere, megafaunal extinctions, cataclysmic floods, the disappearance of the Clovis people and the creation of the Carolina Bays(g), have all been proposed as consequences of this episode.

In 2006, Richard Firestone, Allen West & Simon Warwick-Smith published the foundations of the YDIH in The Cycle of Cosmic Catastrophes [110]. A year later the hypothesis had a more public airing at the American Geophysical Union Press Conference, Acapulco, Mexico, May 23(d). This was followed the same year by the publication of a formal paper in the Proceedings of the National Academy of Sciences of the United States of America(f).

Since then volumes have been written on the subject, both pro and con(c).

A 2014 paper(h) entitled Nanodiamond-Rich Layer Across Three Continents Consistent with Major Cosmic Impact at 12,800 Cal BP by Charles R. Kinzie et al., has developed further the idea of this event being associated with the Younger Dryas. In a similar vein is an article(f) from Megan Gannon.

December 2014 saw Graham Hancock raising the issue of a cometary cause for the Younger Dryas and its possible association with ancient Egypt(e).

Martin Sweatman brought further evidence to bear on this debate in an article(i) on the Graham Hancock website. This focuses on the investigations at Hall’s Cave in Texas described in a paper by Sun et al, where the team concluded that the trace elements found there could indicate a volcanic rather than an impact as the cause of the Younger Dryas cooling! Sweatman disagrees with their conclusions claiming that there seems to be an element of selectivity in choosing data, leading to a wrong conclusion.

>2019 also gave us a paper that included an extensive bibliography and overview of the YDIH debate(k).<

In 2020, the eminent geologist James Lawrence Powell published Deadly Voyager [1911], which offered further support to the YDIH. This book was instrumental in changing the negative stance of a number of ardent sceptics including Michael Shermer(j).

Shermer, Michael

Michael Shermer (1954- ) is the founding publisher of Skeptic magazine and Skeptic.com. Suffering as he does from terminal scepticism, Shermer could not resist offering his views on Atlantis(a), which michael-shermerbasically assume that Plato created the myth of Atlantis to support his political philosophy.>I should note here the comment of Martin Ebon that “the narrative, unlike the Republic, espouses no particular theory and reads more like historical fact, however confusing, than a myth.”[286.16]<

Shermer does accept that Plato mixed history with myth but does not suggest how we might separate the two, instead, he is content to dispose of both baby and bath-water. I consider fatuous, his comment that “Plato’s Atlantean dialogues are essentially an ancient Greek version of Star Wars.” This silly comparison was recently (2018) echoed on an Australian website(d).

Georgeos Diaz-Montexano responded to Shermer’s views with a 2005 article, contentiously entitled Errors, Fallacies and Lies.

Shermer wrote an article(b) for Scientific American (Jan.1.2016) on the subject of ‘Homo Naledi, which generated a highly critical response, noting that Shermer preferred to speculate without evidence and publish an essay without fact-checking.” Even Shermer nods!

However, to give credit where credit is due I must acknowledge that recently (2020)  Shermer, among others, has back-pedalled on their previous sustained opposition to the idea of the Younger Dryas Impact Hypothesis(e). The impetus for this volte-face seems to have been provided by James Lawrence Powell, also a former sceptic, and his book, Deadly Voyager [1911].
