So the reports we have links too refer to a catastrophic event occurring about 10,000 BC that may have helped to end the last ice age. Along with other less catastrophic events that have occurred since then.

Somewhere in the 13,000 to 3,000 BCE, initially just as the most recent period of glaciation of the current ice age was ending. It would be interesting to see if there was something similar initiating each of the past five or six interglacials. I think the ice records go back as far as about 420,000 years in Antarctica. That almost covers about 4 periods of glaciation. The Greenland ice cap is supposed to go back about 110,000 years, so I guess that for proton bombardment events one could correlate what one finds in the ice for the most recent event with sedimentary deposits and then look back farther in similar sedimentary records for more of the same and see if they fall with regularity at the end of glacial periods. I don't think it would be surprising to see periodicity in solar activity responsible, along with some orbital cycles, for initiating and ending glacial and interglacial periods.
