Lee Bement on the Clovis Comet

I happened upon this dated but interesting video of Dr. Leland C. Bement of the University of Oklahoma lecturing on the Younger Dryas Boundary hypothesis. The audio is painfully faint, and I am still watching it, but Bement is a careful, open-minded researcher who is contributing to the investigation. I wonder how his large grant noted here is proceeding?

25:20 minutes seems to be the start of his original research on the subject.
