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 [...]
Boslough 2013–Wittke 1313495110 PNAS comet younger dryas Napier.pdf by George Howard
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 [...]
We find that the increases in 14C and 10 Be at the time of the Younger Dryas are consistent with the airburst of a long-period comet of the suggested mass, making this a plausible scenario.

The breakup in space of a comet or asteroid prior to impact could produce a surface or oceanic impact by the largest object, and hundreds of smaller fragments could create air-bursts affecting an entire hemisphere (Bunch et al. 2012). Approximately 90% of all ejecta from the main impact would fall within five crater radii, although [...]
Large Pt anomaly in the Greenland ice core points to a cataclysm at the onset of Younger Dryas by George Howard
In yet another scurrilous feat of science sample salting, Dr. Allen West and his so-called “Younger Dryas Boundary Team” have now managed to clandestinely contaminate ice core samples from the Greenland Ice [...]
