TL;DR: Geochemical data from five new South Atlantic deep-sea sections indicate that a large mass of carbon dissolved in the ocean at the Paleocene-Eocene boundary and that permanent sequestration of this carbon occurred through silicate weathering feedback.

TL;DR: This paper reviewed events exhibiting evidence for elevated atmospheric CO2, global warming, and ocean acidification over the past ~300 million years of Earth's history, some with contemporaneous extinction or evolutionary turnover among marine calcifiers.

TL;DR: It is shown that sea surface temperatures near the North Pole increased from ∼18 °C to over 23‬°C during this event, which suggests that higher-than-modern greenhouse gas concentrations must have operated in conjunction with other feedback mechanisms—perhaps polar stratospheric clouds or hurricane-induced ocean mixing—to amplify early Palaeogene polar temperatures.

TL;DR: A distinct carbonate-poor red clay layer in deep-sea cores from Walvis ridge is reported, which is term the Elmo horizon, which has similar geochemical and biotic characteristics as the Palaeocene–Eocene thermal maximum, but of smaller magnitude, suggesting that it represents a second global thermal maximum.

TL;DR: In this article, stable hydrogen and carbon isotope measurements of terrestrial-plant and aquatic-derived n-alkanes were used to record changes in hydrology, including surface water salinity and precipitation, and the global carbon cycle.
