Premature rejection in science: The case of the Younger Dryas Impact Hypothesis

James Lawrence Powell publishes masterful takedown of the YD impact deniers

January 10, 2022

Dr. James Powell published an extraordinary review paper this week revealing and carefully detailing the premature (and pathological) rejection of the YDIH. When combined with Martin Sweatman’s work from earlier this year, the whole sorry story of the unprofessional knee jerk opposition to the theory has finally been told….

Global dads decline then plummet after Younger Dryas comet impact

Complex systems rob earth of fathers

August 7, 2021

Tusk buddy Antonio Zamora tipped me off to the paper below revealing that a global loss of genetic males coincides exactly with the comet impact at ~12,882. Tony does an indispensable job surfacing literature highly relevant to the Younger Dryas Impact. I had missed the stunning 2015 gene paper….

Younger Dryas Impact cataclysm evidence exceeds that of UFO's

May 27, 2021

It has been proposed that the Younger Dryas period/GS-1 was initiated by a cosmic impact, for which there is indirect and debated evidence in a large number of sites in the NH surrounding the North Atlantic region (Kennett et al., 2015). A very significant Platinum (Pt) spike has been identified in the GISP2 ice…

Sweatman nails it

Authoritative and readable overview of the Younger Dryas Impact debate published in Earth Science Reviews

May 13, 2021

Indefatigable genius and digital friend of the Tusk, Dr. Martin Sweatman, authored a surprise blockbuster this week. Below is a peer-reviewed and fully accepted pre-online synthesis overview of the Younger Dryas Impact controversy since the very first paper in 2007. ‘The Younger Dryas impact hypothesis: review of the impact evidence’ concludes……

Tusk racks up two co-author citations PER WEEK in 2020

January 1, 2021

If you can’t toot your own horn on New Years, when can you? As a citizen scientist the Tusk is darn proud — and thankful to the credentialed lead authors — to close 2020 with exactly 100 co-author citations. More interesting than my navel, perhaps, is the trend in citations concerning the Younger Dryas…

New media on the Younger Dryas Impact

PBS includes the cosmic cataclysm, and Jim Kennett explains it

December 28, 2020

Between Egypt and the ‘Ro I have neglected to post a lot in the last few months. I’ll be trying to rectify that this year, in part by doing shorter posts with more 3rd party media concerning the Younger Dryas Impact Catastrophe. There have also been a couple of new papers I’ve not posted…

Pro-science skeptic Dr. Marc Defant now supporting #YDIH based on Powell book

June 8, 2020

Dr. Marc Defant did a great thing this morning by announcing on Twitter and his blog that he had come around to support the Younger Dryas Impact Hypothesis. As I told Marc, my respect for his intellectual integrity soared when I saw his tweet….

Younger Dryas Impact Hypothesis validated by very mainstream science publications

April 7, 2020

In the midst of current events and my decades old fascination with disease from space, I failed to notify Tusk readers that the long journey to legitimacy seems done for the Younger Dryas Impact Hypothesis. Last week a relatively obscure publication — but a critical gatekeeper to acceptable science — did a great job…

“A single major asteroid impact would not have caused such widely scattered materials like those discovered at Abu Hureyra,” Kennett said. “The largest cometary debris clusters are proposed to be capable of causing thousands of airbursts within a span of minutes across one entire hemisphere of Earth. The YDB hypothesis proposed this mechanism to…

It is fun to see curious and smart people across the planet learn of our theory, and add content to the internet that allows rational consideration of the Younger Dryas Impact Hypothesis. In a well produced effort, this cat provides some informed science communication. Despite disagreeing with the Tusk on a point or two,…

2019 AGU abstract supports Younger Dryas “exacerbated” by cosmic impact

But cosmic impact follows volcano?

November 23, 2019

Sharma, 2013 This week is “abstract reveal” week for the enormous annual conference of the American Geophysical Union (AGU) held each December (See Tusk at 2009 AGU). So each year around this time I search the AGU website for any coming presentations concerning the Younger Dryas and cosmic impact. Fall Meeting 2019 San Fran…

James T. Teller The Younger Dryas Impact Hypothesis achieved its first publishing “Three-Peet” of supportive papers this month. It started with the Thackeray paper the first week, then came the Moore paper in week two, and now at the end of October comes Teller to make it three blockbusters in a single month. The…

Martin Sweatman goes deep into Younger Dryas bibliography 2007 - 2009

October 20, 2019

Martin Sweatman, when not writing a profound book, is building quite a nice catalog of videos concerning the YDIH and related subjects. This one is particularly welcome and represents the best walk-though of the debate, paper by paper, twist by turn, since Hancock’s careful narration here. This is invaluable science communication and should be…

Younger Dryas Impact Platinum peaks found again in Southern Hemisphere

October 2, 2019

NY Post Gizmodo Quartz Francis Thackeray This confirmation of a South African platinum layer from the Younger Dryas Impact was particularly welcome for several reasons. First, it is another confirmation of evidence for the impact in the Southern Hemisphere, following the Pilauco paper from Chile in March of this year. Second, the lead…

Folks, I am sorry to have been so scarce in recent months. Among other excuses for the inexcusable, the auto-mailer for subscribers to the site went down, and I felt I needed to repair it before posting. Fixing it turned into a mess which led to my continued procrastination. Much has happened in recent…

The main objective of this study was to test the YDB impact hypothesis by analyzing a wide range of data from the Pilauco site in southern Chile. The following conclusions show that our data and interpretations are consistent with the YDB impact hypothesis and we found no evidence that refutes the hypothesis. (1) At…
