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. Overholt & Melott 2013 Cosmogenic nuclide enhancement via deposition from long-period comets as a test of the Younger Dryas…

Mahaney & Keiser 2013

Restored from the library fire 1/11/20
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,…
