The scientific history of Wonderkrater makes this new paper especially compelling. The platinum anomaly was not originally discovered by the Comet Research Group or by scientists closely associated with the Younger Dryas Impact Hypothesis. It...
Two Younger Dryas boundary papers were recently retracted by PLOS ONE. Within hours, critics began circulating the notices as though they represented the long-awaited collapse of the impact hypothesis. They do not. Let’s look plainly...
Dr. Gunther Kletetschka—a proud Cosmic Summit 2025 speaker—has published a must-read paper that delivers another solid blow to the crumbling edifice of skeptical objections to the Younger Dryas Impact Hypothesis (YDIH). The article, titled “Misunderstandings...
“The difficulty lies not so much in developing new ideas as in escaping from old ones.” — John Maynard Keynes Once again, the Comet Research Group has dealt a blow to mainstream serenity. In a...
New Russian Study Extends the Younger Dryas “Black Mat” to Eastern Europe — A Global Cataclysm Confirmed The evidence for a global cataclysm 12,800 years ago—long dismissed by mainstream science—is now undeniable. In a new...

Ancient Calendar, Recently Discovered, May Document a Long-Ago Disaster, NYT, August 12, 2024 This is an incredibly important article considering the sweep of media coverage in the 18 years since the Comet Research Group and...
Comet Research Group member and PhD Candidate Marc Young, of Flinders University in Adelaide, Australia, has made a mammoth 50,000+ word contribution to the YDIH literature. The article analyses the history of the YDIH, including...
Nature link The different age components are used to evaluate the age of each sample. Other information, such as stratigraphy and artifacts, are used to select components most likely to represent the depositional age. We...
The Comet Research Group published profoundly important new data this weekend concerning the Younger Dryas Impact. A series of three papers were led by Dr. Andrew M.T. Moore, former President of the Archaeological Institute of...
A masterful and comprehensive effort here from respected Comet Research Group co-author, Bill Mahaney. Much of the discipline-specific text is hard for the Tusk to fully grasp, and I have had no time to properly review, but I have asked Bill to provide a layman's summary of...
Last month a little noted but fascinating journal article was published providing empirical, genetic evidence for a central claim of the Comet Research Group since 2007: A dramatic loss of life due to the rain of comet fragments.
In 2009 the newly proposed Younger Dryas Impact Hypothesis was knee capped by Surovell et al.

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...
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...
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...
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...
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...

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.
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....
“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...
