Ancient airburst over Ohio

Background from Smithsonian Magazine Breakdown from Archeothoughts Erudite Tusk commentor Stuart Hamish below refers accurately to this Neuheuser and Neuheuser paper responding to Tankersley et al., as “hair splitting.” I’d agree. Stuart also includes some juicy tidbits about other modern impacts that are worth sharing. Incidentally, I plan to take Stuart up on his suggestion…

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 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 up an interesting hit.

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, Francis Thackeray, is no light weight, as…

The Bos & Co

Late to the Party

An instructive video accompanies the paper I’m trying to get out of town for a beach weekend, but I’ve wanted to get this paper up for days. The newly prominent role of the Taurids among American space scientists, with the role of The Bos discussed in a recent Tusk post here, is peculiar but not unwelcome. Fortunately, and perhaps for sake of the authors’ sense of integrity, the…

Wally Broecker says a cosmic impact caused the Younger Dryas

I realize that this subject is distasteful to many because of the early false claims. But the new evidence suggests that there was some kind of extraterrestrial impact. Hence it should be given further study. I remember pleading with Science’s Richard Kerr to do a piece on this discovery. He thought about it and decided that, as he had written a very negative piece about the original idea, he…

We all know the Tusk enjoys the study of past catastrophes but is less interested in blogging on space borne threats to our future. The intellectual real estate of future apocalypse — Repent! — is too well populated on the internet for us.

Two Ivies in two months confirm YD impact: Pinter of Southern Illinois - Carbondale to NBC: "Fringe science," questions integrity of National Academy of Sciences

A meteor or comet impact near Quebec heaved a rain of hot melted rock along North America’s Atlantic Coast about 12,900 years ago, a new study claims. Scientists have traced the geochemical signature of the BB-sized spherules that rained down back to their source, the 1.5-billion-year-old Quebecia terrane in northeastern Canada near the Gulf of Saint Lawrence. At the time of the impact, the…
