Peer review working?

YDIH dominates science community readership stats

December 7, 2019

The science publishing and peer-review process gets a lot of grief, often for good reason. Many fruitful areas of paradigm changing research languish outside the major journals and never pass from the gatekeepers to the printing press. But thankfully the YDIH, despite the controversy and “robust” debate, appears regularly in the world’s top earth science […]

Stefan Milo sits on fence

December 6, 2019

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 […]

Praetorious investigating "mysterious" Younger Dryas materials

Reaches out on Twitter to help ID odd discovery in marine core

November 26, 2019

I can’t quite recall where I first heard of Summer Praetorious, but she is a respected professional in our area of inquiry. So I was intrigued today to see Summer post a pic of a collection of rather odd materials from a Younger Dryas marine core sample. Mighty cool. Cheers to Summer for sharing the […]

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 turned […]

Updated Younger Dryas Impact Hypothesis Bibliography and Paper Archive

Now with READ IT function!

Tireless Aussie Marc Young has done it again. During his summer holiday Marc has managed to link every YDIH peer-reviewed journal article directly from the bibliography spreadsheet. My idea to have a slick “accordion file” of all the papers at the bottom of the page was simply ahead of its time, and this is a […]

George Howard interview links

November 9, 2019

The Cosmic Tusk has had the good fortune to join several podcasts in the last couple of years to discuss the Younger Dryas Impact Hypothesis. I am a HUGE podcast fan, and unlike TV, narrow subject fiends like myself stand a chance to get on the air. The experience of speaking on our subject, instead […]

Permanent Younger Dryas Impact Bibliography and Paper Archive

November 8, 2019

Welcome to the permanent host page for the most comprehensive bibliography of scientific literature concerning the Younger Dryas Impact Hypothesis. The bibliography was compiled in a collaboration between the Tusk and Mr. Marc Young, an Australian Archaeology & Enviro-Sci undergrad who performed most of the meticulous work. Significantly, this page will include not only the […]

Tusk challenges Rogan to question Tyson regarding the Younger Dryas Impact Hypothesis

November 6, 2019

The Tusk recently appeared as a guest on the UnchartedX YouTube series. It was fun and I have a lot of respect for Ben’s work to publicize the YDIH and the Comet Research Group. But if had to do the podcast over again, I would have made more than a passing reference to an idea […]

Randall on Halloween

October 31, 2019

Randall Carlson does a great job here explaining a really creepy but profound aspect of the Younger Dryas Impact Hypothesis. Halloween, like death festivals worldwide in late October\early November, reflects the trauma inflicted by the Taurid Meteor stream on the ancients during recurring bombardments. As Bill Napier described it once to me, Earth’s intersection with […]

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 […]

See permanent page here Readers may recall a few months ago the Tusk and Australian university student Marc Young compiled a bibliography and archive file of all the YDIH publications since the seminal PNAS publication in 2007. I have taken the files and given them a permanent home here. The publication history of the subject […]

YDIH Literature Review Part One

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 viewed […]

YouTuber explains worldwide religion in context of the Younger Dryas impact

October 12, 2019

Tusk video from Tall el-Hammam Ben at UnchartedX continues to produce excellent videos concerning the Younger Dryas Cataclysm and related subjects. Just recently he posted this superbly produced review of religious and mythical information and how it perfectly matches the hard science of impacts. Warning: This stuff is heavy, and as Ben points out, it […]

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 author, […]
