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…

Mucked Up

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 rained Platinum rich…

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…

Broecker to Kunzig: This Deal is Real

Readers will recall the awkwardly titled September post, “NatGeo actually calls Wally Broecker to discuss evidence for cosmic impact at Younger Dryas start.” The Tusk was trying to convey there my astonishment that a thoughtful and thorough article was written on recent advances in the study of the Younger Dryas Boundary. Only later, with very little digging, did I realize this was…

Extraordinary Evidence and Inexplicable Ignorance: Bunch (2012) and The Bos (2013)

Bunch Boslough It is telling to read competing journal articles regarding the Younger Dryas Boundary Event. For example below is the recent paper from The Bos, et al., and below that a publication from the YDB team the year before. (I was added as an author to that one based on some field work I did years before starting this blog). There are a number of interesting observations that…

Rise of the Zombie: Harvard Discovers Evidence for Major Earth Impact at Younger Dryas Initiation (~12,875 BP)

Update: As published in PNAS in July, 2013 “The [Younger Dryas Boundary] theory has reached zombie status,” said Professor Andrew Scott from the Department of Earth Sciences at Royal Holloway. “Whenever we are able to show flaws and think it is dead [!], it reappears with new, equally unsatisfactory, arguments. [Sniff!] – “January 30, 2013, Royal Holloway Press…
