Stable Carbon CycleClimate Relationship During the Late Pleistocene
A record of atmospheric carbon dioxide (CO 2 ) concentrations measured on the EPICA (European Project for Ice Coring in Antarctica) Dome Concordia ice core extends the Vostok CO 2 record back to 650,000 years before the present (yr B.P.). Before 430,000 yr B.P., partial pressure of atmospheric CO 2...

Summary: | A record of atmospheric carbon dioxide (CO 2 ) concentrations measured on the EPICA (European Project for Ice Coring in Antarctica) Dome Concordia ice core extends the Vostok CO 2 record back to 650,000 years before the present (yr B.P.). Before 430,000 yr B.P., partial pressure of atmospheric CO 2 lies within the range of 260 and 180 parts per million by volume. This range is almost 30% smaller than that of the last four glacial cycles; however, the apparent sensitivity between deuterium and CO 2 remains stable throughout the six glacial cycles, suggesting that the relationship between CO 2 and Antarctic climate remained rather constant over this interval. |
