WikiLies: Skeptical Raptor squelches science

The accuracy of information concerning the YDB event on the Wikipedia has always suffered from the dominance of a moderator describing himself as “Skeptical Raptor.” Watching the Raptor do his wiki-work has taught the Tusk that cynicism has few bounds — and the truth has few friends (that stay up that late at night). The Raptor constantly cleanses the public’s Wiki of any…

Younger Dryas Event in California

One of the most intense debates in the paleosciences in recent years has focused on the question of whether or not a cosmic impact (comet) approximately 12,900 years ago caused both the Younger Dryas climatic oscillation and the disappearance of Pleistocene megaauna in North America. Since it was frst advanced in print by Firestone et al. (2007), the Younger Dryas Boundary (YDB) impact…

Steamed: Ted Bunch From the Heart On Boslough and Scott

This afternoon former NASA geochemist Ted Bunch dropped the Tusk the note below. It is thrilling to see a core YDB researcher with a five decade track record [and here] willing to stand up to his bullies in frank and personal terms, outside the stilted literature and self-serving press releases. The recent Boslough et al. paper and coordinated press releases are insulting to Dr. Bunch.

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 our debate. Despite confirmation of this extraordinary material in the…

YDB Co-Author Profile: Paul S. DeCarli

Paul DeCarli Nick Pinter claims here that diamonds were misidentified in earlier YDB studies. The paper this month was Paul DeCarli’s first formal appearance with the YDB team but his presence as a co-author undermines Pinter’s accusation. DeCarli is a diamond pro. And more importantly he is an eager scientist more given to discovery than criticism. I have seen the old fellow out…

Seek and Ye Shall Find: ET material confirmed in Murray Springs Black Mat

At the end of the Pleistocene a Younger Dryas black mat was deposited on top of the Pleistocene sediments in many parts of North America. A study of the magnetic fraction (~10,900±50 B.P.) from the basal section of the black mat at Murray Springs, AZ revealed the presence of amorphous iron oxide framboids in a glassy iron-silica matrix. These framboids are very similar in appearance and…

Trust but Verify: Independent confirmations of the Younger Dryas Impact Boundary

Skeptics of the YDIB hypothesis frequently state that “no one can reproduce the YDIB results” (Kerr, 2010); “nobody has found anything” (Kerr, 2010); there is a “lack of reproducibility of data” (Holliday, 2011); and “unique peaks in concentrations at the YD onset have yet to be reproduced” Pinter (2011). These casual dismissals are hurtful to the investigation, demonstrably false…

Skeptic Speaks: A Personal Essay from Vance Holliday on the Clovis Comet

Vance Holliday Vance Holliday was thoughtful to give the Tusk a heads up on his essay first published here at the Argonaut.  I have not read it throughly enough to respond myself right now, but I am certain of this: One or more of the dozen key researchers from the other side of the debate should write something similar.  His tender tale of woe and misunderstanding is exceeded only by their…

Blast from past: YD team member diciplined by Golden State geo board in 2002

I have nothing but an iPhone until later tomorrow. So this post is necessarily brief. Allen West has taken a hit to his credibility (and to some extent the Tusk’s) from charges by Younger Dryas Hypothesis critics ranging from professional misconduct to falsifying lab results. As an advocate of Allen’s and someone who has spent years watching him personally sacrifice with no financial…
