I remember hearing on the Joe Rogan podcast[1] about a theory of an impact at the end of the last glacial period, resulting in a short-term reversal of the warming trend known as the Younger Dryas Cooling Event. There was quite a bit of evidence in the form of meltglass and other things accumulating, but the theory was very much not accepted by mainstream science at the time. From the article it sounds like this idea is getting more support.
Randall Carlson is pretty out there with his one massive flood theory as opposed to many smaller events. Nonetheless he's not an idiot by any means and he gives an enthralling account of the climate events at the time.
Also it sounds like a much more credible explanation for the sudden extinction of large mammals (70% of species in North America.) Only Africa was largely unaffected. Including 100 million mammoths dying off which was previously attributed to human over-hunting - just the logistics of which with spears and primitive bows boggles the mind.
