Open Letter: Napier on Defant and the Joe Rogan podcast

June 25, 2017

Bill Napier sent the Tusk a note regarding Joe Rogan’s unforgettable debate-style podcast on the Younger Dryas Boundary Hypothesis. Bill’s message is posted below my rant here. His informed correction of Marc Defant’s self-styled skeptical authority on comets is priceless and instructive. A cultural genre of all-purpose professional “skeptics,” like Defant and Shermer, have emerged since […]

The Cosmic Tusk Carolina Bay media file

June 4, 2017

Click here for a public link to the file The Tusk has had several requests for Carolina Bay images lately, including drone video for a forthcoming episode of “What On Earth?”, the most popular show on Discovery Science. In the process of putting my material together in one place, I realized how cool it would […]

The Younger Dryas Impact Hypothesis since 2007

According to Hancock

May 21, 2017

I recently discovered an essay from Graham Hancock that manages to convey both the profound intellectual significance — and petty scholastic drama — of the Younger Dryas Impact Hypothesis since 2007. Hancock doesn’t note his good timing, but as he writes in 2017 it is the 10th anniversary of the Comet Research Group’s Acapulco AGU presentations introducing […]

Joe Rogan hosts epic 3.5 hour podcast debating the Younger Dryas impact

May 17, 2017

Almost 24 hours later and I am still catching my breath. Last night’s Joe Rogan Experience podcast was pure heaven for the Tusk. As folks might have noted, the world’s most popular interview podcast has taken a long-standing interest in our subject. Graham Hancock has appeared on Rogan six times in recent years, I believe, […]

World's leading website: Daily Mail online touts full story of Younger Dryas impact significance

May 2, 2017

Daily Mail on the Younger Dryas Impact Suppose all the wildest theories and historical conspiracies of novelist Dan Brown were proven true. And the mind-reading, spoon-bending claims of Israeli psychic Uri Geller all turned out to be real as well. That wouldn’t be half as extraordinary as the announcement in an obscure scientific journal this […]

Datestamp: World's oldest monument memorializes Younger Dryas comet impact

April 21, 2017

  Response from Gobekli Tepe dig and back at you from Edinburg What DID that fox say? Times of London YouTube Ok, I’ve finally found a little time to provide some commentary after posting the Gobekli Tepe \ YD Comet paper last week. I have more substantive comments underway (believe it or not) but first I […]

Recent papers critical of the Younger Dryas Impact Hypothesis: Daulton and Scott

February 22, 2017

  I have provided some counter points below to the arguments made in the recent publications from Daulton and Scott (regular critics). However, I was particularly disturbed to see that the papers failed to include very significant confirmations of our work, for instance Adronikov 2016. Unlike Tian (2011) and Bement 2014. Daulton claims failure to […]

Problem solved?: Carolina Bays are shock liquefaction impact features from hypersonic ice boulders launched from the glacial ice sheet by a cosmic impact at the Younger Dryas

January 22, 2017

A. Zamora The Tusk was absolutely thrilled to see the publication last week of a paper concerning Carolina Bays in the distinguished journal, Geomorphology. Other than a brief role for the Carolina bays in the early papers of the Comet Research Group, and a much longer series of Geological Society of America posters laboriously researched […]
