The Bib Gets Graphic: Nearly Twenty Years of the Younger Dryas Debate at a Glance
Three new graphics trace nearly twenty years of Younger Dryas impact literature, with 254 peer-reviewed entries and 107 non-peer-reviewed entries to explore.
The Tusk’s renovation continues. This time, we’ve given The Bib something a long list of references has always needed: a way to see the big picture.
Three new graphics let readers explore the history of the Younger Dryas impact literature before diving into the individual papers. The collection represented includes 254 peer-reviewed entries and 107 non-peer-reviewed entries, with 2026 marked as a partial year.
That is a considerable pile of reading. Now you can get your bearings first.
Viewpoints over time
The first graphic groups the peer-reviewed entries by publication year and their editorial classification in the bibliography. Supportive, critical, and other assessments appear together, giving readers a visual guide to how the published discussion has developed.
Publication cadence
The second graphic shows the annual flow of peer-reviewed entries, distinguishing comments and replies from other publications. A new investigation and a reply to someone else’s investigation both belong in the record, but it helps to see which is which.
Beyond peer-reviewed literature
The third graphic provides a separate timeline for the bibliography’s non-peer-reviewed collection. The wider discussion has a history of its own, and now that history is easier to explore as well.

A word about what we are counting: these are bibliography entries. They are not 254 independent experiments, and the colored categories reflect editorial judgments about the papers. Science is not settled by counting publications. The value of these graphics is that they help readers find their way into the evidence—and the arguments over it.
Special thanks to Marc Young, whose meticulous work maintaining The Bib over the years made all of this possible. A chart is the visible part. Finding, reading, organizing, and keeping track of the literature is the work beneath it, and Marc deserves the credit.
Please take a look, share the page, and send us corrections, missing references, or suggestions about the classifications. The more useful we make this resource, the easier it becomes for anyone arriving at the debate to examine the record for themselves.
Nearly twenty years after the first 2007 paper, there is plenty to examine.
