University of Arizona confirms spherule concentration in lower YDB sediments at famed Clovis site Blackwater Draw

 

Blackwater Draw

The presence of a high number of the hollow magnetic microspherules can be used for identification of the LYDB. Although some scientists failed to find any microspherules at all along the LYDB in the BWD-1 site (Surovell et al. 2009), others reported strongly elevated concentrations of […]

#YDB impact confirmed again: Volcanos and Asteroids and Mammoths — Oh My!

My dear Kepler, I wish that we might laugh at the remarkable stupidity of the common herd. What do you have to say about the principal philosophers of this academy who are filled with the stubbornness of an asp and do not want to look at either the planets, the moon or the telescope, […]

Nice Dice?: The Bos disputes Harvard

It is safe to say The Bos is becoming obsessed. Someone please count and let me know, but I believe he has four publications this year seeking to undermine the Younger Dryas Boundary Hypothesis. Over time he has published more than a dozen. Today he is back in PNAS — alone — […]

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 […]

Clovis Comet paper #1 read article in Geology

The wisdom of crowds is comforting. Despite the near total news blackout of the recent developments related to our subject, readers have shot Anders Carlson’s 2010 free paper, What Caused the Younger Dryas Cold Event?, to the top of the Most Read articles in the journal Geology.

I am not surprised. This is an absolutely […]

PNAS: Five-Year study rips spear from back of YDB hypothesis

 

iPaper_embed(‘106210252’, ‘key-2i68bycjgm0wdjsmqc1j’, ‘600’, ‘450’); Working on getting the paper. [Update: Got it above}

This appears to be the long hoped for independent, intentional, blind, professional and reproducible confirmation of the original 2007 findings of the Younger Dryas Boundary team.

Independent evaluation of conflicting microspherule results from different investigations of the Younger Dryas […]

Dutch Diamonds Demand Extraordinary Explanations

The Aalsterhut / Hut van Mie Pils

The recent paper from van Hoesel et al., Nanodiamonds and wildfire evidence in the Usselo Horizon postdate the Allerød-Younger Dryas Boundary, confirming nanodiamonds in the Dutch Younger Dryas Boundary (YDB), or Usselo Horizon, establishes a cynical new low for the intellectual integrity of […]

Elevated Iridium at Younger Dryas in England

A reader recently asked by email why, if cosmic blast materials have been found on the continent in Germany and the Netherlands in Younger Dryas sediments, has nothing been found in the British Isles? Or how about just plain old England, one of the best studied countries on earth?

My correspondent is […]

Game Changer: Independent Confirmation of ET Materials in Arizona and Dutch Black Mats

Your correspondent was doing some navel gazing last night and checked the academic “cites” for the soon to be even more famous 2007 paper, “Evidence for an extraterrestrial impact 12,900 years ago that contributed to the megafaunal extinctions and the Younger Dryas cooling.”

I’ll be darned if I did not come across a just-added citation […]
