Sentences with phrase «as hyperthermals»

He has a particular interest in the relationship between volcanism and past climate change, including the possible trigger mechanisms for the enigmatic warming events known as hyperthermals, such as the PETM.

Not exact matches

In the case of the PETM and other Cenozoic hyperthermals, the CO2 may be the initial cause, so it would be treated as a forcing rather than a feedback.

Methane hydrates — methane molecules trapped in frozen water molecule cages in tundra and on continental shelves — and organic matter such as peat locked in frozen soils (permafrost) are likely mechanisms in the past hyperthermals, and they provide another climate feedback with the potential to amplify global warming if large scale thawing occurs [209]--[210].

The mechanisms behind these hyperthermals are poorly understood, as discussed below, but they are characterized by the injection into the surface climate system of a large amount of carbon in the form of CH4 and / or CO2 on the time scale of a millennium [205]--[207].

The similarities of these other hyperthermals with the PETM were taken as being suggestive of a common mechanism (s) giving rise to them all.

Ying's research deals with carbon cycles during ancient hyperthermal events, such as the Paleocene - Eocene Thermal Maximum and the end - Permian mass extinction event.

It will be valuable for future studies to understand the magnitude, rate, and relative temporal phasing of redox changes as they are expressed in spatially diverse locations, in order to provide constraints on the heterogeneity of climatically important feedback processes operating during the PETM, and other hyperthermals.

These controls are extremely similar to those highlighted as critical drivers of anoxia during the Mesozoic Oceanic Anoxic Events, suggesting that the PETM should be considered in a similar vein to these older hyperthermals.
