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.

Large Pt anomaly in the Greenland ice core points to a cataclysm at the onset of Younger Dryas
The impact hypothesis (11), once declared dead (12, 13), recently gained new support from the discovery of siliceous scoria-like objects (SLOs) with global distribution, which…

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 fine material is expected to be random distributed over a much…
