Atmospheric CO₂ concentration from 60 to 20 kyr BP from the Taylor Dome Ice Core, Antarctica

Abstract

A high‐resolution record of the atmospheric CO 2 concentration from 60 to 20 thousand years before present (kyr BP) based on measurements on the ice core of Taylor Dome, Antarctica is presented. This record shows four distinct peaks of 20 parts per million by volume (ppmv) on a millennial time scale. Good correlation of the CO 2 record with temperature reconstructions based on stable isotope measurements on the Vostok ice core (Antarctica) is found.
