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…

Airbursts/impacts by a fragmented comet or asteroid have been proposed at the Younger Dryas onset (12.80 ± 0.15 ka) based on identification of an…

Excerpts
I have a huge library of catastrophist books, both printed and now electronic. They range from horribly kooky and shallow to books that have millions of copies in their future. Dr. Jeffrey Goodman’s The Comets of God is closer to the latter. It will be read and re-read, particularly by Christians, and remembered as the best resolution of modern comet science and biblical text…
