Dendrochronologist Mike Baillie on impacts more recent than Younger Dryas

February 28, 2018

Hear the British Library interview Dr. Baillie Jonny McAneney’s Tusk comment on his collaborator Mike Baillie’s paper: This is an important paper, but it is equally important to point out that scientific understanding has moved on in the decade or so since this was published. I have posted before on this site about the corrections […]

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 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 […]
