ABSTRACT
CO
2
and Miocene Climate Change
Atmospheric carbon dioxide is a powerful greenhouse gas believed to be one of the most important determinants of climate. Ice cores provide a detailed and direct record of CO
2
concentrations over the past 800,000 years, but not earlier.
Tripati
et al.
(p.
1394
, published online 8 October) report B/Ca measurements of planktonic foraminifera, from which they can infer atmospheric CO
2
concentrations, for the past 20 million years. The concentration of atmospheric CO
2
was similar to preindustrial values for the past 10 millions years, but between 15 and 20 million years ago, during the warm lower Miocene epoch, CO
2
was more abundant, and major climate transitions toward cooler conditions occurred when CO
2
decreased substantially.
