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 that Halley’s Comet may have caused this, by leaving a dust trail that the Earth…

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 later, with very little digging, did I realize this was…

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 been premature. In this game that counts as a win.

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 Burchard in the South China Sea and posted last…

There seems to be a recent update to Google Earth,– apologoizing for over-reliance on this dubious source — the ocean between Vietnam and the Phillipines, the South China Sea. At least, I have not seen this much detail on earlier…

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 TV and Anderson Cooper did a surprising and praise worthy job last Sunday with a couple of Tusk-worthy follow-up questions…

Flam responds in KSJT comments?
Below is a link to a very poorly written, intellectually depressing and kinda mean press blog out of MIT. Flam does not distinguish Dartmouth’s Markul Sharma et al. from the original Firestone authors despite the point of her lede. Later she updates her blog to correct another less significant — but also easily discoverable —…
