(Thread) I know I'm a bit late to the party, but I've decided to weigh in on the ICS subdivisions, and the start of the “Meghalayan” at 4.2 ka. For the past year, my colleagues @hannahkolus , @DKaufman1 and I have been looking into the Holocene significance of the 4.2 ka event. Specifically, we’ve been wondering whether the event stands out as an unusual period of abrupt change (broadly defined) at that time, regionally or globally, or whether the combination of societal impact and confirmation bias has over-inflated its importance.
