Termination of global warmth at the Palaeocene/Eocene boundary through productivity feedback

  title={Termination of global warmth at the Palaeocene/Eocene boundary through productivity feedback},
  author={Santo Bains and Richard D. Norris and Richard M. Corfield and Kristina Faul},
The onset of the Palaeocene/Eocene thermal maximum (about 55 Myr ago) was marked by global surface temperatures warming by 5–7 °C over approximately 30,000 yr (ref. 1), probably because of enhanced mantle outgassing and the pulsed release of ∼1,500 gigatonnes of methane carbon from decomposing gas-hydrate reservoirs. The aftermath of this rapid, intense and global warming event may be the best example in the geological record of the response of the Earth to high atmospheric carbon dioxide…

Could changing ocean circulation have destabilized methane hydrate at the Paleocene/Eocene boundary?
[1] During the Paleocene-Eocene Thermal Maximum (PETM, ∼55 Ma), marine and terrestrial carbon isotope values exhibit a negative shift of at least 2.5‰, indicative of massive destabilization of marine
The Palaeocene-Eocene Thermal Maximum Super Greenhouse: Biotic and Geochemical Signatures, age Models and Mechanisms of Climate Change
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.

In both the early Toarcian and early Aptian cases, the negative carbon–isotope excursion precedes global excess carbon burial across a range of marine environments, a phenomenon that defines these intervals as oceanic anoxic events (OAEs).
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
Global dinoflagellate event associated with the late Paleocene thermal maximum
The late Paleocene thermal maximum, or LPTM (ca. 55 Ma), represents a geologically brief time interval (∼220 k.y.) characterized by profound global warming and associated environmental change. The
Rapid and sustained environmental responses to global warming: the Paleocene–Eocene Thermal Maximum in the eastern North Sea
Abstract. The Paleocene–Eocene Thermal Maximum (PETM; ∼ 55.9 Ma) was a period of rapid and sustained global warming associated with significant carbon emissions. It coincided with the North Atlantic
[1] A major perturbation of the global carbon cycle ∼55 million years ago, believed to result from release of 1000–2000 Gt of C from methane hydrates, correlates with an intense but transient
Modelling the carbon cycle during the Paleocene-Eocene thermal maximum
The Paleocene-Eocene Thermal Maximum (PETM, ∼56 million years ago) was a transient global warming event, characterized by a prominent negative carbon isotope excursion (CIE) in the proxy record, most

Enhanced terrestrial weathering/runoff and surface ocean carbonate production during the recovery stages of the Paleocene‐Eocene thermal maximum
[1] The carbonate saturation profile of the oceans shoaled markedly during a transient global warming event known as the Paleocene-Eocene thermal maximum (PETM) (circa 55 Ma). The rapid release of

Carbon cycling and chronology of climate warming during the Palaeocene/Eocene transition
Current models of the global carbon cycle lack natural mechanisms to explain known large, transient shifts in past records of the stable carbon-isotope ratio (δ13C) of carbon reservoirs. The
Dissociation of oceanic methane hydrate as a cause of the carbon isotope excursion at the end of the Paleocene
Isotopic records across the “Latest Paleocene Thermal Maximum“ (LPTM) indicate that bottom water temperature increased by more than 4°C during a brief time interval (<104 years) of the latest

Marine oxygen isotope records indicate a substantial warming of the surface and deep ocean waters across the Paleocene/ Eocene boundary at the late Paleocene thermal maximum (LPTM, c. 55 Ma). A

Early Paleogene warm climates may have been linked to different modes and sources of deepwater formation. Warm polar temperatures of the Paleocene and Eocene may have resulted from either increased
A blast of gas in the latest Paleocene: simulating first-order effects of massive dissociation of oceanic methane hydrate.
Significant CH4 release from oceanic hydrates is a plausible explanation for observed carbon cycle perturbations during the thermal maximum because the flux of CH4 invoked during the maximum is of similar magnitude to that released to the atmosphere from present-day anthropogenic CH4 sources.
