Kerr Watch

Elapsed time since Richard Kerr failed to inform his Science readers of the confirmation of nanodiamonds at the YDB: 5 years, 11 months, and 18 days

Trust but Verify: Independent confirmations of the Younger Dryas Impact Boundary

Skeptics of the YDIB hypothesis frequently state that “no one can reproduce the YDIB results” (Kerr, 2010); “nobody has found anything” (Kerr, 2010); there is a “lack of reproducibility of data” (Holliday, 2011); and “unique peaks in concentrations at the YD onset have yet to be reproduced” Pinter (2011). These casual dismissals […]

Smoke Linked to Gun: Napier upheld by Nesvorný and Jenniskens on Zodiacal Cloud and short-period Comets

Richard Kerr, the oldest rat in the barn over at Tusk competitor Science Magazine, has written a disturbingly matter-of-fact piece reporting the myth busting work of David Nesvorný and Peter Jenniskens (hereafter N&J) on the source of Interplanetary Dust and the Zodiacal Cloud. N&J are the same fellows who last month deduced massive […]

New Paper: Sea Level jump at onset of Younger Dryas?

There was an interesting paper from Science last week concerning sea-level rise in and around the Younger Dryas. It looks as though there may have been a relatively small — but dramatically fast– rise in Sea-Level just before the YD:

Deglacial Meltwater Pulse 1B and Younger Dryas Sea Levels Revisited with Boreholes at Tahiti, from […]

Younger Dryas Boundary: Extraterrestrial or Not? AGU Fall Meeting 2009

I was fortunate to attend the YDB session in San Francisco at the Fall Meeting of the American Geophysical Union. With a young family and a growing business it is tough — and selfish — to pull away to the West Coast to play scientist two weeks before Christmas. But I did. And I appreciate […]
