Grad student scoops major Journal

It is truly disturbing to see a young grad student do a quick blog for AGU and reveal fundamentally new earth science — while the top writer for Science can sit in the 2nd row and not publish a word.

Dukin’ Out the Younger Dryas Boundary:

The question: What caused the thousand plus year Younger Dryas cold snap that likely killed off the mammoths, saber-toothed cats, and other iconic ice-aged creatures ~12,000 years ago?

In one corner were those who believe that impact from a swarm of comets caused the cooling event. In the other: the skeptics.

Wallace Broecker of the Lamont-Doherty Earth Observatory started the talk out with fighting words: “As far as a comet goes, I never believed it.” He claimed that the only evidence for a blast from outer space is the presence of nano-sized diamonds in the layer of sediment from that time period, and those don’t even prove impact.

Allen West of GeoScience Consulting led the pro-impact camp. He and his colleagues rocked the field when they published a paper in 2007 and another in 2009 suggesting the idea. He argued that the nanodiamonds are, in fact, proof of a major bang, since no other situation could produce the anaerobic conditions and the pressures and temperatures to make them

  • Hi George; Thankyou very much for your diligence in providing what is a very good summary of the AGU conference. I will comment further upon further study. But for now are you interested in my book? I think it would help tie up some of the loose ends, not presented in ond place before? I think as an aside that it is deplorable that Richard Keer sat without recording anything at all. I am finding the journal Science (I suspect nature too) to be a bastion of dogmatic attitudes. They have neither printed my letter re: Jacqueline Gill’s work nor even acknowledged receival of my book I sent in their books received every week section. Such is the nature of people working on the fringes so to speak. Why this should be a fringe area is however beyond me. Sincerely, Rod.
