Short summary
This paper analyzes the uniqueness of a paleoclimate event entitled the Bølling–Allerød Younger Dryas (BA/YD) through a statistical lens in order to better understand its relation to other events similar to it. Furthermore, we implement a novel statistical method entitled PCOut in order to measure the BA/YD's various elements of uniqueness in existing paleoclimate records. We suggest future use of this method for paleoclimate research that aims to assess uniqueness across multiple criteria.
