Abstract: 

Knowledge of past atmospheric pCO(2) is important for evaluating the role of greenhouse gases in climate forcing. Ice core records show the tight correlation between climate change and pCO(2), but records are limited to the past similar to 900 kyr. We present surface ocean pH and PCO2 data, reconstructed from boron isotopes in planktonic foraminifera over two full glacial cycles (0-140 and 300-420 kyr). The data co-vary strongly with the Vostok PCO2-record and demonstrate that the coupling between surface ocean chemistry and the atmosphere is recorded in marine archives, allowing for quantitative estimation of atmospheric pCO(2) beyond the reach of ice cores.
