PETM Caused by Passing Star?

The Paleocene Eocene Thermal Maximum (PETM) was a geologically brief spike in temperatures, during the warmest climatic episode of the Cenozoic Era.
We are often told that the warmth of the Early Paleogene was driven by CO2; and that the cool-down from the Late Paleogene, into the Neogene and Quaternary Periods was driven by a draw-down of atmospheric CO2; however there is scant evidence for this hypothesis[1][2]. Despite the paucity of geological evidence, the notion of a CO2-driven climate has apparently become a paradigm.
This paradigm didn’t exist in the 1970’s.
