Napier vindicated

20 March 2012

Following on from yesterday (Bill Napier email from 2005) the YD impact hypothesis is revisited at http://craterhunter.wordpress.com/2012/03/16/the-younger-dryas-impact-hy… in which the author begins by saying the team presenting the YD boundary event were not writing from a solid astronomical model – and that is what got them into trouble with the critics. This was because they were relying on Toon et al and the estimate they made that it would take a 4 mile wide bolide to account for a continent wide debris layer. Dennis Cox, on the other hand, has stuck rigidly to the idea of an airburst and Clube and Napier's hypothesis concerning the Taurid complex.
