New Younger Dryas Impact Hypothesis Paper

New Younger Dryas Impact Hypothesis Paper

There is a new Younger Dryas Impact hypothesis paper. It is;

Kennett, J. P., D. J. Kennettb, B. J. Culleton, and many others,
2015, Bayesian chronological analyses consistent with
synchronous age of 12,835–12,735 Cal B.P. for Younger
Dryas boundary on four continents. Proceedings of the
National Academy of sciences of the United States.
Early Edition, James P. Kennett, doi: 10.1073/pnas.1507146112

Some comments about it:

Another article of his is “Platinum spikes extra-terrestrial

There is an another paper, which found that the environmental
changes that mark the beginning of the Younger Dryas are
diachronous in their time of occurrence according to latitude.
Along latitude 56–54°N, they ocurred as early as c. 12,900–13,100 cal. BP,
while further north they ocurred at c. 12,600–12,750 cal. BP.

environmental shifts across Northern Europe at the onset of
the Younger Dryas. Quaternary Science Reviews. 109:49–56.
