TL;DR: In this article, the authors report proxy records of sea surface temperatures from multiple ocean localities and show that the high-latitude temperature decrease was substantial and heterogeneous, and that Northern Hemisphere glaciation was not required to accommodate the magnitude of continental ice growth during this time.

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: This record of the Neogene reveals cooling of the Arctic that was synchronous with the expansion of Greenland ice and East Antarctic ice and supporting arguments for bipolar symmetry in climate change.

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.

TL;DR: It is shown that using a mantle reference frame, which defines plate positions relative to the mantle, instead of a paleomagnetic reference frame may introduce errors in paleolatitude of more than 15° (>1500 km), because mantle reference frames cannot constrain, or are specifically corrected for the effects of true polar wander.
