Her team's research is the first to address the effects of the paleocene-eocene thermal maximum (petm) -- a relatively brief period of global climate change, spanning 200,000 years -- on marine. The paleocene-eocene thermal maximum (petm) was a period of natural global warming that took place almost 56 million years ago it came at a time when the atmospheric concentration of co2 was already higher than today, and global temperatures also much warmer.
The paleocene-eocene thermal maximum (petm) hyperthermal, ~ 56 million years ago (ma), is the most dramatic example of abrupt cenozoic global warming during the petm surface temperatures increased between 5 and 9 °c and the onset likely took 20 kyr.
Eocene thermal maximum 2 (etm-2), also called h-1 or the elmo (eocene layer of mysterious origin) event, was a transient period of global warming that occurred approximately 537 million years ago (ma. Paleocene-eocene thermal maximum: paleocene-eocene thermal maximum (petm), a short interval of maximum temperature lasting approximately 100,000 years during the late paleocene and early eocene epochs (roughly 55 million years ago) the interval was characterized by the highest global temperatures of the cenozoic era (65 million.
The paleocene–eocene thermal maximum (petm) is one of the most intense and abrupt intervals of global warming in the geological record. The paleocene–eocene thermal maximum (petm ca 55 ma) is a relatively short-lived (~ 200 kyr) transient climatic event characterised by a large negative excursion in stable carbon isotope ratios, a prominent shoaling of the global ocean carbonate compensation depth (ccd) and a widespread positive temperature anomaly (zachos et al, 2005, sluijs et al, 2007a.
Arctic hydrology during global warming at the paleocene/eocene thermal maximum nature 442, 671-675 robert, c, and jp kennett, 1994 antarctic subtropical humid episode at the paleocene-eocene boundary - clay-mineral evidence geology 22, 211-214 schmitz, b, rp speijer, and mp aubry, 1996. Cycle, climate, and biosphere with implications for the future petm, global warming, paleoclimate, paleoecology, carbon cycle following the paper by kennett and stott on what has come to be known as the paleocene-eocene thermal maximum (petm), koch et al (1992) measured the negative carbon isotopic.
A comet strike may have triggered the paleocene-eocene thermal maximum (petm), a rapid warming of earth caused by an accumulation of atmospheric carbon dioxide 56 million years ago, which offers. The paleocene-eocene thermal maximum: a perturbation of carbon cycle, climate, and biosphere with implications for the future petm, global warming, paleoclimate, paleoecology, carbon cycle abstract during the paleocene-eocene thermal maximum (petm), ∼56 mya.
