WebbAccording to the hypothesis, the PETM was triggered when large deposits of methane hydrates in ocean sediments were warmed to the point at which methane was released through the ocean and into the atmosphere in large quantities. The methane then oxidized, forming carbon dioxide. Webb11 nov. 2010 · The Paleocene-Eocene thermal maximum (PETM) was a transient episode of global warming, associated with massive atmospheric greenhouse gas input that occurred at the Paleocene/Eocene boundary. Webb1 dec. 2003 · These results would necessitate a rise in atmospheric pCO2 to levels three to four times as high as those estimated for the late Paleocene.
