Unfortunately, the overcrowded session ran late, and there was no time for discussion or questions. Even when their conclusions were challenged, most of the scientists in the audience chose not to respond. The result was a lost opportunity for real debate.

Indeed, following the AGU and GSA meetings, the YD impact hypothesis seems to have retreated into the obscurity of a few e-mail list-serves and blogs, such as “The Cosmic Tusk” where George Howard (one of the original PNAS authors) is presiding over a variety of catastrophist interpretations of Holocene history— David Morrison, NASA, MayJune 2010
