A persistent critic of the Younger Dryas Impact Hypothesis and the Comet Research Group has lately gone quiet on our favorite subject. As the supporting papers and independent confirmations have rolled in, Mark “The Bos” Boslough, is scarcely heard from. His last report even seemed a clumsy attempt to scramble on board with a central […]

An instructive video accompanies the paper I’m trying to get out of town for a beach weekend, but I’ve wanted to get this paper up for days. The newly prominent role of the Taurids among American space scientists, with the role of The Bos discussed in a recent Tusk post here, is peculiar but not […]

Some wag tweeted this funny cartoon today depicting the current state of affairs in Younger Dryas Boundary Research. The storyboard calls out The Bos and Vance Holliday for their willful ignorance with regard to the Younger Dryas Impact Hypothesis. The clever and extraordinarily well informed cartoonist points out the awkward position The Bos has created for […]

Oh, lordy, bring me my salts. I do feel the vapours coming on. You could have knocked the Tusk over with a feather at the Apple Store yesterday when my phone linked to the The Bos in the Washington Post, presenting at 2018 AGU, and pimping to the world: The Taurids are a threat! The […]

Martin Sweatman, like The Bos, is a betting man. But in this instance I want his side of the wager. Today Sweatman published a masterpiece of original, rational statical analysis reporting a series of planetary catastrophes as recorded by our elders in ancient symbols in cave art and carved rock. The historic rejection of ancient animal […]

Who knew? The Bos is a betting man. The recently retired federal scientist, global warming enthusiast, and unsuccessful Republican candidate for the New Mexico State Senate, tweeted his interest in a wager this week concerning the likelihood that the Hiawatha impact in Greenland would have occurred recently enough to cause the Younger Dryas climate crash, […]

Paleolithic Extinctions and the Taurid Complex (2010) Centaurs as a Hazard to Civilization (2015) Excerpted from Page 11 Wolbach et. al Part One (2018)   Astronomical Hypothesis for the YDB Impact Event Regarding the probability of a swarm of cometary fragments hitting the Earth, Boslough et al. (2013) claimed that the YDB event is “statistically […]

  As a rule, the Tusk is scrupulously clean of politics. There is a reference in my own blog bio to being a former conservative policy staffer in the US Senate, but that is background and not polemics. I am old fashioned and believe politics is generally if not inherently destructive of sound inquiry. The more political […]

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 […]
