Paper on Comet/Asteroid Impact Causing the Younger Dryas Cooling.

But it is much worse to seek to remove an appearent coincidence with an specific explanation whose probability is even less than the coincidence.

That would be something so intellectually vile that it would actually be pleasing to the Christian.

Come now....xtians think fucking "god" is throwing asteroids at earth for shits and giggles.

Haven't they also found nanodiamonds in the black mat?

[Minimalist]

Yes.

We present detailed geochemical and morphological analysesof nearly 700 spherules from 18 sites in support of a majorcosmic impact at the onset of the Younger Dryas episode (12.8ka). The impact distributed
10 million tonnes of meltedspherules over 50 million square kilometers on four con-tinents. Origins of the spherules by volcanism, anthropogenesis,authigenesis, lightning, and meteoritic ablation are rejected ongeochemical and morphological grounds. The spherules closelyresemble known impact materials derived from sur
ficial sedi-ments melted at temperatures 2,200 °C. The spherules corre-late with abundances of associated melt-glass, nanodiamonds,carbon spherules, aciniform carbon, charcoal, and iridium.

The black mat is the Younger Dryas Boundary (YDB).
