Praetorious investigating "mysterious" Younger Dryas materials

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 mystery. Can anyone help me with this mystery sample? It is unlike anything I have…

2019 AGU abstract supports Younger Dryas "exacerbated" by cosmic impact

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, now, finally, the YDIH literature is fully &#8212…

Tusk on Tape

The Cosmic Tusk has had the good fortune to join several podcasts in the last few years  years to discuss the Younger Dryas Impact Hypothesis. I am a big podcast fan, and unlike TV, narrow subject fiends like myself stand a chance to get on the air. The experience of speaking, instead of writing, has progressed from unnerving to much more relaxed, even enjoyable. And now that I have several…

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 of mine. In the podcast, I suggested Joe Rogan question his regular guest Neil DeGrasse Tyson about his thoughts…
