The first paper for our paper club is this recent one from McKay et al., presenting a thorough investigation of the (supposed?) 4.2 ka event. I'd read it when it was published, but just went through again in more detail, and what a good paper. Robust stats (of course, from this group), and they do a really nice job of building the case. I hope the group enjoys it!

NatureThe 4.2 ka event is not remarkable in the context of Holocene climate variability - Nature CommunicationsA study of more than 1000 paleoclimate datasets reveals that the ”4.2 ka event” is not a globally significant climate excursion, unlike the prominent 8.2 ka event. In the Holocene, site-level excursions are common, but global-scale events are rare.
