Exploring abrupt climate change induced by comets and asteroids during human history

Second suspected Greenland crater announced by NASA

Hat tip from Steve Garcia posted December 31st on the Tusk

February 11, 2019

Only at the Cosmic Tusk can you expect to see a major global announcement by NASA scooped by six weeks. Thanks to our blog’s most dedicated contributor, Steve Garcia: You heard it here first. See other, non-prescient, contemporaneous coverage here: NBC:  Immense crater may have been found deep under Greenland’s ice sheet PhysOrg: NASA finds possible second […]

Cuba popped by meteor

Same old sky snake

February 2, 2019

The Tusk doesn’t generally report on current impact phenomena, and focuses instead on past impacts. But it never hurts to show some cool videos on a blog. First is from terrified residents of Vianales, Cuba on February 1st, 2019, shocked by the delayed arrival of the concussion, and staring in wonder and disbelief at the […]

Version 1.5

January 31, 2019

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 […]

2009 NOVA on the Younger Dryas Impact Hypothesis

January 27, 2019

11:05 No crater? 48:23 Jim Kennett in a wonderful moment During a fleeting period at the end of the last decade, a decade ago, the YDIH was a burgeoning mainstream topic. So popular in fact that the “Cadillac” of science TV, PBS NOVA, did an absolutely beautiful hour-long 2009 episode on the ice age comet discovery and […]

The Bos and Vance Holliday in the funny papers

January 15, 2019

Some wag tweeted this funny cartoon today depicting the current state of affairs in Younger Dryas Boundary Research. The storyboard calls out The Bos and Vance Holliday for their willful ignorance with regard to the Younger Dryas Impact Hypothesis. The clever and extraordinarily well informed cartoonist points out the awkward position The Bos has created for […]

Bright Insight

YouTube wisdom on Younger Dryas Impact Hypothesis

January 1, 2019

Jimmy at Bright Insight has posted a masterpiece of science and speculation concerning the YDIH. How do these guys do this? I would find it very, very difficult to prepare all this info and share it in such a coherent manner on camera. Some of his other videos are just tad too speculative, even for […]

Hiawatha Crater central peak

Hiawatha Discovery Team member Anders Bjork tweets 3D crater model

December 31, 2018

As most crater heads know, a “central peak” within a bowl shaped depression is diagnostic of a large “complex crater” resulting from a highly energetic (to say the very least) cosmic collision. Though NASA made an effort to point out the subtle peak features of Hiawatha Crater beneath a mile of erosive ice, the portion […]

Another crater?

Second feature found inland of Hiawatha may be hinted 2nd Greenland crater

Longtime Tusk buddy and dedicated Catastrophist Steve Garcia went crater hunting and located IMHO a great candidate for the second crater hinted at by NASA scientist Dr. Joe MacGregor of the Hiawatha Discovery Team. He was thoughtful to send the Tusk the first image below of the suspect dimple beneath a mile of ice. I […]

The Bos gets religion?

Mark Boslough discovers Taurid stream threat in late June -- 40 years after Clube and Napier

December 27, 2018

Oh, lordy, bring me my salts. I do feel the vapours coming on. You could have knocked the Tusk over with a feather at the Apple Store yesterday when my phone linked to the The Bos in the Washington Post, presenting at 2018 AGU, and pimping to the world: The Taurids are a threat! The […]

Saginaw Bay fingered by gravity data as ice impact feature

Davias and Harris at Cintos.org vindicated

December 22, 2018

Wow. The cascade of stupefying new discoveries continues. A paper published today in the Journal of Great Lakes Research provides evidence from gravity anomalies that Saginaw Bay in Michigan is a remnant feature of an impact into an ancient ice sheet. This and the recent discovery of Hiawatha Crater make for an interesting configuration. But […]

Always a bride's maid...

Science has named nine scientific advances as runners-up for the 2018 Breakthrough of the Year.

December 21, 2018

Seriously, it is really cool to see Science Magazine name Hiawatha Crater as 2018 breakthrough story runner up — and with due reference to the Younger Dryas Impact Hypothesis. The crater will be an intellectual gift that keeps on giving, and its better days are ahead. So I will go ahead and nominate the article […]

From my new friends, Brothers of the Serpent  Episode #078: George Howard We have a very special episode for all you snake sibs out there, we interviewed Mr. George Howard, who has been involved with the Comet Research Group from the very beginning in the work on the Younger Dryas Impact Hypothesis, which we have spoken […]

Tusk on the Carolina Bays

What I REALLY think

In the weeks following the Hiawatha Crater discovery, I took the opportunity to post a personal note concerning the Younger Dryas Impact Hypothesis on my Facebook page. Deeper in the thread as a result of some comments I took the opportunity to give my “2018 take” on the Carolina bays. Here is my comment, excerpted […]

Greenland icebergs may have triggered Younger Dryas

Hiawatha?

December 7, 2018

This paper from five years ago seems consistent with the Hiawatha Impact Crater. Some 13,000 years ago, as the last Ice Age seemed to lose its cold grip on the Earth, the temperature suddenly plunged again. Up to now, scientists believed that the Younger Dryas cold reversal was caused by great amounts of Canadian meltwater […]

Mucked Up

A year later, not a word on Alaska paper in Nature with evidence for repeated cataclysm

December 3, 2018

It’s hard to be cynical enough in this game. I noted today that “Science Communicators,” a recently discussed poorly adapting subspecies, have yet to mention this blockbuster paper in Nature Reports one year ago. Specifically, there is credible preliminary evidence contained by the bucketful that there was a catastrophe prior to the Younger Dryas Impact that […]

The Hiawatha Crater and Global Warming politics

Science communicators give tongue to cats

November 30, 2018

In addition to the recent history of the earth, its animals, and mankind, the Hiawatha Crater discovery may have something else to teach us. The Tusk finds the real-time sociological implications of the crater as fascinating and instructive as the feature itself. I’m obsessed by what the new information reveals about the motivations and perspective […]

Sweatman and Coombs lay odds on Gobekli Tepe and the Younger Dryas comet

November 28, 2018

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 […]
