Abstract Extreme global warmth and an abrupt negative carbon isotope excursion during the Paleocene–Eocene Thermal Maximum (PETM) have been attributed to a massive release of methane hydrate from sediments on the continental slope [1] . However, the magnitude of the warming (5 to 6 °C [2] , [3] ) and rise in the depth of the CCD (> 2 km; [4] ) indicate that the size of the carbon addition was larger than can be accounted for by the methane hydrate hypothesis. Additional carbon sources… Expand
