During the Paleocene-Eocene Thermal Maximum (PETM), ∼56 Mya, thousands of petagrams of carbon were released into the ocean-atmosphere system with attendant changes in the carbon cycle, climate, ocean chem- istry, and marine and continental ecosystems. The period of carbon release is thought to have lasted <20 ka, the duration of the whole event was ∼200 ka, and the global temperature increase was 5-8 ◦ C. Terrestrial and marine or- ganisms experienced large shifts in geographic ranges, rapid…

The Paleocene‐Eocene Thermal Maximum: How much carbon is enough?

The Paleocene-Eocene Thermal Maximum (PETM), ∼55.53 million years before present, was an abrupt warming event that involved profound changes in the carbon cycle and led to major perturbations of

A seasonality trigger for carbon injection at the Paleocene–Eocene Thermal Maximum

Abstract. The Paleocene–Eocene Thermal Maximum (PETM) represents a ~170 kyr episode of anomalous global warmth ~56 Ma ago. The PETM is associated with rapid and massive injections of 13C-depleted

Environmental impact and magnitude of paleosol carbonate carbon isotope excursions marking five early Eocene hyperthermals in the Bighorn Basin, Wyoming

. Transient greenhouse warming events in the Paleocene and Eocene were associated with the addition of isotopically light carbon to the exogenic atmosphere–ocean carbon system, leading to substantial

The reconstruction invokes volcanic emissions as a driver of PETM warming and suggests that the buffering capacity of the ocean increased, which helped to remove carbon dioxide from the atmosphere, but estimates confirm that modern CO2 release is occurring much faster than PETM carbon release.

The dynamics of global change at the Paleocene‐Eocene thermal maximum: A data‐model comparison

We integrate published stable isotopic, chemical, mineralogical, and biotic data from the onset of the Paleocene‐Eocene thermal maximum (PETM) at Site 690, Maud Rise in the Southern Ocean. The

The Palaeocene – Eocene Thermal Maximum (PETM), a hyperthermal event that occurred ca. 56 Ma, has been attributed to the release of substantial amounts of carbon, affecting the atmosphere, biosphere

Rapid and sustained surface ocean acidification during the Paleocene-Eocene Thermal Maximum

The Paleocene-Eocene Thermal Maximum (PETM) has been associated with the release of several thousands of petagrams of carbon (Pg C) as methane and/or carbon dioxide into the ocean-atmosphere system

The Italian record of the Palaeocene-Eocene Thermal Maximum

The present paper summarises the state of the art of the studies on Italian Palaeocene-Eocene Thermal Maximum (PETM) records. The PETM (~ 56 Ma) likely represents the most dramatic and rapid event of



A humid climate state during the Palaeocene/Eocene thermal maximum

The authors' results provide evidence for a previously unrecognized discrete shift in the state of the climate system during the PETM, characterized by large increases in mid-latitude tropospheric humidity and enhanced cycling of carbon through terrestrial ecosystems.

Productivity feedback did not terminate the Paleocene-Eocene Thermal Maximum (PETM)

Abstract. The Paleocene-Eocene Thermal Maximum (PETM) occurred approximately 55 million years ago, and is one of the most dramatic abrupt global warming events in the geological record. This warming

On the duration of the Paleocene‐Eocene thermal maximum (PETM)

The Paleocene‐Eocene thermal maximum (PETM) is one of the best known examples of a transient climate perturbation, associated with a brief, but intense, interval of global warming and a massive

The Palaeocene–Eocene Thermal Maximum (PETM), a geologically brief episode of global warming associated with the Palaeocene–Eocene boundary, has been studied extensively since its discovery in 1991.

Nannoplankton Extinction and Origination Across the Paleocene-Eocene Thermal Maximum

The Paleocene-Eocene Thermal Maximum was an interval of global warming and ocean acidification attributed to rapid release and oxidation of buried carbon that appears to have driven turnover, preferentially affecting rare taxa living close to their viable limits.

Effects of Rapid Global Warming at the Paleocene-Eocene Boundary on Neotropical Vegetation

Palynology shows that the tropical rainforest was able to persist under elevated temperatures and high levels of atmospheric carbon dioxide, in contrast to speculations that tropical ecosystems were severely compromised by heat stress.
