Kerr Watch

Number of days writer Richard Kerr has failed to inform his Science readers of the confirmation of nanodiamonds at the YDB: 3 years, 11 months, and 30 days

Half a loaf from B612: Asteroid data from nuke blast detectors calls out faulty impact assumptions; older impact data ignored; nothing new

Live updates and edits underway

Press release from B612 Foundation

UPDATE:  B612 Impact Video 4-20-14 H264 from D Josh Rosen on Vimeo.

The Tusk works mightily to avoid speculating about future cosmic impacts at the expense of reporting evidence for such events in the human past, but recent news intervenes once more. [...]

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 — and in [...]

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 later, with [...]

Two Ivies in two months confirm YD impact: Pinter of Southern Illinois – Carbondale to NBC: “Fringe science,” questions integrity of National Academy of Sciences

A meteor or comet impact near Quebec heaved a rain of hot melted rock along North America’s Atlantic Coast about 12,900 years ago, a new study claims.

Scientists have traced the geochemical signature of the BB-sized spherules that rained down back to their source, the 1.5-billion-year-old Quebecia terrane in northeastern Canada near the Gulf [...]

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 [...]

Napier: Not So Fast Bos….

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. The Taurid Complex appears to [...]

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 the [...]

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 [...]
