Did the Black-Mat Impact/Airburst Reach the Antarctic? Evidence from New Mountain Near the Taylor Glacier in the Dry Valley Mountains Journal of Geology, March 15, 2018 Detailed microscopic investigations of horizons in a surface paleosol, part of a pedostratigraphic stack of tills at New Mountain, Antarctica, dated to the middle Miocene climatic optimum event (ca. 15 Ma), suggest not only that…

Getting its propers: Younger Dryas Boundary takes center stage in Fall 2015 bestseller from Graham Hancock

Magicians of the Gods from Amazon The Joe Rogan Experience The Tusk has a large library of books related to catastrophism. I love them all. From the laboratory inspired to the ridiculously speculative, the range of publications touching on what happened 12,800 years ago is delightfully enormous. Unfortunately, many of these books have painfully small sales — sometimes in inverse proportion…

PNAS: Diamond peak confirmed at YDB -- and Bronze Age collapse, perhaps?

Table 1. Bement video Earlier GSA abstract Co-author spotlight: Andrew S. Madden Carter, Simms, Benamara…. PNAS Lexus lane? 46,000 hits! Significance In 2007, scientists proposed that the start of the Younger Dryas (YD) chronozone (10,900 radiocarbon years ago) and late Pleistocene extinctions resulted from the explosion of a comet in the earths atmosphere. The ET event, as it is…

Fair Enough: Van Hoesel breaks down YDB science in critical review

Annelies Van Hoesel (Dr. Van Hoesel yet?) recently published an overview of Younger Dryas Boundary Hypothesis in Quaternary Science Reviews. I hear at least one of the YDB authors found it terribly biased against the impact. But it seems to me that she is implicitly admitting that the many obituaries of the YDB impact have been premature. In this game that counts as a win. View The Younger Dryas…

Le Bos, mais pourquoi pas la France?!

But why not France, Bos!? The news release Independent investigators have failed to confirm the reports of enhanced concentrations of spherules and platinum-group elements in YD boundary sediments. Boslough, Surovell et al., January 30, 2013, Arguments and Evidence Against a Younger Dryas Impact Event Interhemispheric evidence of a cosmic impact 12.9 ka is known now…

Salt in the Wound: The Bos Not Reading Papers

Obviously, this whole “salting” thing from The Bos has got me hopping mad — and for good reason. By implying that the sites were “salted,” The Bos raises the issue of fraud or conspiracy surrounding the modern date he got on his YDB carbon spherule from Gainey, Michigan. But there’s a problem with that accusation — the YDB group published a modern date of the same…

Finally Available in PNAS: Very High Temperature Impact Melt Products: Evidence for Cosmic Impacts Airbursts 12,900 years ago

These scientists have identified three contemporaneous levels more than 12,000 years ago, on two continents yielding siliceous scoria-like objects (SLO’s),” said H. Richard Lane, program director of National Science Foundation’s Division of Earth Sciences, which funded the research. “SLO’s are indicative of high-energy cosmic airbursts/impacts, bolstering the contention that these events…

YDB impact researchers cite confirmations in recent PNAS paper

The PNAS paper has a helpful bibliography of recent publications supportive of the hypothesis. It’s worth a separate block quote below. Nice how the links take you to the cites themselves at the PNAS website. “Some independent workers have been unable to reproduce earlier YDB results for MSp, CSp, and NDs (6⇓–8), as summarized in a “News Focus” piece in Science (9)…
