Comment on "Abrupt warming events drove Late Pleistocene Holarctic megafaunal turnover"
Cooper et al. (Research Article, 7 August 2015, p. 602) combined the annual layer counted Greenland Ice Core Chronology 2005 with chronological information from the Hulu Cave and Cariaco Basin records to produce a "revised" time scale. We argue that their time scale is incompatible with the nature of annual layer counted time scales and may lead to seriously flawed conclusions if used elsewhere at face value.
