Mahaney....Again!: New Evidence from a Black Mat Site in the Northern Andes Supporting a Cosmic Impact 12,800 Years Ago

Source: JOURNAL OF GEOLOGY Volume: 121 Issue: 4 Pages: 309-325 DOI: 10.1086/670652 Published: JUL 2013 Abstract: Previous work has ascribed a cosmic impact origin to black, high-temperature, carbon-encrusted beds (2–3 cm thick), associated with the Younger Dryas readvance of ice at 12.8 ka during the Late Glacial in the northern Andes of Venezuela. The evidence for this includes carbon…

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…

Chilton Raved at Watts Up

Rod Chilton of BCC Climate has a guest post on the Younger Dryas over at Watts Up With That that is lighting up the boards, and bringing some welcome new attention to our subject. It also seems that blog force Anthony Watts has taken an interest in the Younger Dryas Boundary Event, having posted three times now on the subject. Wonderful. We are in an uphill fight with dogma it seems &#8212…

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…

Kerr on Limb: Science writer misleads peeps in public post

Distinguished Science writer Dr. Richard Kerr walked the plank this afternoon in response to this morning’s Knight Science Journalism Tracker inquiry of science writers. Charles Petit’s casual post brought quick attention from the old-school dean of science writing. Kerr implored his press colleagues to, in effect: Move on, move on…There is nothing to see here. See here: I…
