Schmidt, Gavin A.NASA, Goddard Institute for Space Studies, New York, NY, United StatesauthorShindell, Drew T.authorAmerican Geophysical Union, Washington, DC, United StatespublisherdocumentDigitalPaleoceanography18 (1)4.1-4.9The massive perturbation to global climate and the carbon cycle during the Paleocene/Eocene Thermal Maximum (PETM) may have been forced by a catastrophic release of methane gas (CH (sub 4) ) from hydrate deposits on the continental slope. We investigate whether reported PETM paleotemperature and paleo-CO (sub 2) proxies are consistent with this hypothesis by considering the impact of large increases in CH (sub 4) emissions to the atmosphere. Significant effects on atmospheric chemistry and CH (sub 4) lifetime are seen for a range of plausible emission rates.
