Slow release of fossil carbon during the Palaeocene-Eocene Thermal Maximum
@article{Cui2011SlowRO, title={Slow release of fossil carbon during the Palaeocene-Eocene Thermal Maximum}, author={Ying Cui and Lee R. Kump and Andy Ridgwell and Adam J. Charles and Christopher K.

A brief period of warming 55.9 Myr ago has been attributed to the release of massive amounts of carbon. Geochemical and model data suggest the peak rate of carbon emission during this interval was relatively slow, and significantly lower than present-day levels of carbon emissions to the atmosphere.

Stable carbon isotopic values of di-unsaturated alkenones extracted from deep sea cores are used to reconstruct pCO2 from the middle Eocene to the late Oligocene and demonstrate that it ranged between 1000 to 1500 parts per million by volume in the middle to late Eocene, then decreased in several steps during theOligocene, and reached modern levels by the latest Oligaen.
