Excerpt: The most extreme change in Earth surface conditions during the Cenozoic Era began at the temporal boundary between the Paleocene and Eocene epochs . This event, the Paleocene-Eocene Thermal Maximum (PETM, alternatively (ETM1), and formerly known as the "Initial Eocene" or ,"" (IETM/LPTM)), was associated with rapid (in geological terms) global warming, profound changes in ecosystems, and major perturbations in the carbon cycle. Global temperatures rose by about 6 C (11 F) over a period of approximately 20,000 years. Many benthic foraminifera and terrestrial mammals went extinct, but numerous modern mammalian orders emerged. The event is linked to a prominent negative excursion in carbon stable isotope ( C) records from across the globe, and dissolution of carbonate deposited on all ocean basins. The latter observations strongly suggest that a massive input of 13C-depleted carbon entered the hydrosphere or atmosphere at the start of the PETM. Recently, geoscientists have begun to investigate the PE...
