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…

Here They Go Again: Holliday and Surovell use dozer not trowel

Surovell-Holliday 2012 Tusk commentary Vance Holliday and Todd Surovell published a paper in PLOS One this week. It is unsurprising but again disappointing that these hacks continue their jihad on the YDB hypothesis based on negligent analysis. Particular galling is their wanton substitution of an optical microscope for an electron microscope. I say “wanton” because the publication…

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…

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…

Napier: Not So Fast Bos....

The banner image above is Comet 73/P Schwassman-Wachmann fragmenting in orbit ABSTRACT Intersection with the debris of a large (50-100 km) short-period comet during the Upper Palaeolithic provides a satisfactory explanation for the catastrophe of celestial origin which has been postulated to have occurred around 12900 BP, and which pre-saged a return to ice age conditions of duration 1300 years.

Typical: Boslough ignores LeCompte

[See comments: Boslough responds!] Boslough et al’s recent paper gives no less than nine separate citations to Todd Surovell’s 2009 publication: An independent evaluation of the Younger Dryas extra-terrestrial hypothesis. The multiple references are not surprising given that the Surovell paper has become a totem of Boslough and other’s crusade to end research into…

Holy Hagiography!: Boslough "Jonesed" By Sandia Labs

I have seen some fawning press releases in my day but this is the most obsequious schlock I have ever encountered. Mark or his mum must have stayed up real late writing this one. I seriously doubt any “synthesis” rebuttal paper containing so little original work (What did kill all those animals? Global warming?) has ever been touted by a federally funded institution in so silly and…

Unfiltered: Surovell - Holliday in PNAS, 2009

To a great degree the Tusk itself was a response to my frustration with Todd Surovell and Vance Holliday’s botched 2009 PNAS journal article, “An independent evaluation of the Younger Dryas extraterrestrial impact hypothesis,“ published three months before this blog began. Despite my early understanding of the sloppy work of the authors, however, I did not have the data or…

Breaking: Ducks join Gamecocks with press release calling out Surovell, et al. 2009

Today’s press release from the University of Oregon complimenting yesterday’s from the University of South Carolina. Surovell, et. al 2009 has another serious challenge here. Challengers to Clovis-age impact theory missed key protocols, new study finds EUGENE, Ore. — (Sept. 18, 2012) — An interdisciplinary team of scientists from seven U.S. institutions says a…

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…
