It is safe to say The Bos is becoming obsessed. Someone please count and let me know, but I believe he has four publications this year seeking to undermine the Younger Dryas Boundary Hypothesis. Over time he has published more than a dozen. Today he is back in PNAS — alone — and in the face of Harvard scientists who independently discovered to their surprise an extraordinary spike of Platinum in the Greenland ice core at precisely the point in time predicted by YDB hypothesis.
It is also fair to say The Bos has staked his professional reputation on the non-occurrence of the climate changing Younger Dryas impact. He has never hedged his bet in the least, which is an interesting position considering the nature of the purported event. Either a globe cooling cosmic encounter happened ~12,875 years ago — or it didn’t. It might take a decade or two (dammit) but the reality of the event will be determined one way or another. It has a binary quality.
If Mark Boslough has calculated wrong, he will judged one of the most damaging skeptics in the history of science. He has fought mightily, and I would argue quite spitefully, to bury an idea. Find a single example of him calling for further research into the YDB impact and I will buy you a Coke.
So as proof builds for such an impact one would certainly think he would become anxious and more hesitant. Oh, no. He publishes more! I would not be surprised if The Bos frequents Vegas. He certainly seems to have a taste for the dice.
