Melott 2013

We find that the increases in 14C and 10 Be at the time of the Younger Dryas are consistent with the airburst of a long-period comet of the suggested mass, making this a plausible scenario.

    The forensics keep coming in.

    What’s the score now, Bos?

    Bos? I can’t hear you!

    The INTCAL98 14C chart showed even sharper spikes than this smoothed chart.

    Perhaps Libby’s conjecture from 1952 has been demonstrated:
    in impact, some photons reach energy levels sufficient to split the nucleus’s of atoms. (Now know as nucleons.)

    If this holds, then perhaps unusual isotopes will be found in abundance at Meteor (Barringer) Crater in Arizona.

    This just when we are being told that a comet could not have been the Tunguska object.

    Both types can impact, so I think we will always find some of both that either can or cannot be. Each past impact stands on its own. Each future one as well. SOME day we will have enough data and evidence to be able to sort it out which is which – but that day is not this day.
