Is [_Science_ good enough](http://science.sciencemag.org/content/329/5996/1140)?

How about [this](https://www.researchgate.net/publication/251557038_The_Younger_Dryas_impact_hypothesis_A_requiem) one?

Or [this](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4938604/) one?

Or [this](https://blogs.scientificamerican.com/history-of-geology/httpblogsscientificamericancomhistory-of-geology20110727the-younger-dryas-impact-hypothesis/)?

Or pick your own from the citations in [the Wikipedia article](https://en.wikipedia.org/wiki/Younger_Dryas_impact_hypothesis#Criticism).

The story was horseshit by crackpots more than 10 years ago when I first started reading about it, and is horseshit from crackpots today.
