The Paleocene–Eocene thermal maximum (PETM), alternatively "Eocene thermal maximum 1" (ETM1), and formerly known as the "Initial Eocene" or "Late Paleocene thermal maximum", was a time period with a more than 5–8 °C global average temperature rise across the event. This climate event occurred at … Visa mer The configuration of oceans and continents was somewhat different during the early Paleogene relative to the present day. The Panama Isthmus did not yet connect North America and South America, and this allowed … Visa mer Clear evidence for massive addition of C-depleted carbon at the onset of the PETM comes from two observations. First, a prominent negative … Visa mer Precipitation The climate would also have become much wetter, with the increase in evaporation rates … Visa mer Climate proxies, such as ocean sediments (depositional rates) indicate a duration of ∼83 ka, with ∼33 ka in the early rapid phase and ∼50 ka in … Visa mer A study in 2024 estimated the Global mean surface temperature (GMST) with 66% confidence during the latest Paleocene (c. 57 Ma) as 22.3 to 28.3 °C, PETM (56 Ma) as 27.2 to 34.5 °C, … Visa mer The timing of the PETM δ C excursion is of considerable interest. This is because the total duration of the CIE, from the rapid drop in δ C through the near recovery to initial conditions, … Visa mer Discriminating between different possible causes of the PETM is difficult. Temperatures were rising globally at a steady pace, and a … Visa mer Webb18 aug. 2024 · The PETM is the warmest of several short, very warm periods or “hyperthermals” that occurred in the late Paleocene and early Eocene between 56 and 53 …
