Loose Goose: The Bos all over the map

Long ago the Tusk noted a fascinating 2010 missive from The Bos concerning the virtue of everyone (else) remaining intellectually flexible. Or, as he put it, having a willingness to “change your mind.” Here is the link and I have copied the text at the bottom.

The Bos’ statement has not aged […]

Nice Dice?: The Bos disputes Harvard

It is safe to say The Bos is becoming obsessed. Someone please count and let me know, but I believe he has four publications this year seeking to undermine the Younger Dryas Boundary Hypothesis. Over time he has published more than a dozen. Today he is back in PNAS — alone — […]

Did a 6th Century Comet Bring Global Famine?

Evidence from tree rings and ice cores suggest that parts of Europe, Asia and North America saw protracted cooling in the 530’s, which has been linked to drought and famine. Some scientists hypothesize […]

Broecker to Kunzig: This Deal is Real

Readers will recall the awkwardly titled September post, “NatGeo actually calls Wally Broecker to discuss evidence for cosmic impact at Younger Dryas start.” The Tusk was trying to convey there my astonishment that a thoughtful and thorough article was written on recent advances in the study of the Younger Dryas Boundary. Only […]

Fair Enough: Van Hoesel breaks down YDB science in critical review

Annelies Van Hoesel (Dr. Van Hoesel yet?) recently published an overview of Younger Dryas Boundary Hypothesis in Quaternary Science Reviews. I hear at least one of the YDB authors found it terribly biased against the impact. But it seems to me that she is implicitly admitting that the many obituaries of the YDB impact have […]

Heinrich disputes Burchard

Clarifying note: The Tusk, not Dr. Burchard, suggested the name Crater Burchard for this feature. And yes, I know. Craters are named for nearby geographic features, not people.

The always smug but relatively well informed Paul Heinrich had a post on the Meteorite-list serve today disputing the cosmic origin of circular features identified by Hermann […]

Tick, Tick, Tick, Tick, Tick, Tick, Tick: 60 Minutes’ Cooper nails NASA’s Yeomans and Chodas on common asteroid threat

We all know the Tusk enjoys the study of past catastrophes but is less interested in blogging on space borne threats to our future. The intellectual real estate of future apocalypse — Repent! — is too well populated on the internet for us.

But great TV is great […]
