I was excited today to order a newly published book concerned 100% with the Younger Dryas Impact Event. The author is long-tenured and highly respected geologist, college president, museum director and writer, Dr. James Lawrence Powell. The book can be purchased from Amazon here.

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 covering […]

“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 account for the widely dispersed coeval materials across more than 14,000 kilometers of the Northern and Southern Hemispheres. Our Abu Hureyra discoveries strongly support a major impact event from such a fragmented comet.”

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, it […]

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 turned […]

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 Teller […]

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 viewed […]

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 author, […]

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 months […]

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 Pilauco, […]

Permanent home of the Bib and Archive Long on the list of goals here at the Tusk is to host the world’s most concise, attractive, accessible and informative bibliography of our favorite subject. A baby step in that direction is submitted below for your perusal, download and propagation. With the help of Marc Young, here […]

Martin Sweatman, like The Bos, is a betting man. But in this instance I want his side of the wager. Today Sweatman published a masterpiece of original, rational statical analysis reporting a series of planetary catastrophes as recorded by our elders in ancient symbols in cave art and carved rock. The historic rejection of ancient animal […]

Bos Bet… Voosen article in Science Magazine Seven Ages Daily Mail National Geographic BBC NYT MSN Oh, happy day! The Tusk heard about this discovery confidentially in March but the following nine months were characterized by an uncertain confidence this day would truly come. We had published evidence for a decade, and knew a climate […]

See another blockbuster confirmation of the Younger Dryas cosmic impact below. I keep a pretty close eye on our subject but had no idea such intricate, original and thorough work was underway in the Czech Republic. Gunther Kleteschka has appeared on several YDB papers, but has clearly been busy in his own laboratory collecting entirely […]

I realize that this subject is distasteful to many because of the early false claims. But the new evidence suggests that there was some kind of extraterrestrial impact. Hence it should be given further study. I remember pleading with Science’s Richard Kerr to do a piece on this discovery. He thought about it and decided […]

A friend sent me this paper from Dr. Martin Sweatman who gained international notoriety last year with a previous journal article linking the world’s most ancient temple, Gobekli Tepe in Turkey, with the Younger Dryas Impact. The Tusk enjoyed that paper and was pleased to see Sweatman make a second contribution to our field; this […]
