Holocene Impact Working Group
The Holocene Impact Working Group (HIWG)(a) was created by researchers into different aspects of geosciences, who believe that cometary impacts were more frequent during the recent past than generally accepted. It is concerned with the growing number of impact craters being discovered and the evidence of consequent mega-tsunamis. Its membership includes Mike Baillie, Richard Firestone and Bruce Masse(b).
>I note that the idea of such a Holocene impact is denied by some, such as Jennifer Marion who presents in a 2012 paper “arguments and evidence against the hypothesis that a large impact or airburst caused a significant abrupt climate change, extinction event, and termination of the Clovis culture at 12.9 ka. “(d)<
The New York Times reviewed the work of the HIWG in 2006(c).
