“…Among the models included in the EoMIP, the Community Climate System Model version 3 (CCSM3) of the National Center for Atmospheric Research (NCAR) (the model used in the present paper; Methods) gave the closest match to data, likely because the CCSM3's vigorous polar amplification (43) allows it to match high-latitude temperature records well once the global mean value is warm enough. Although significant discrepancies with individual data points remain (14,21), this match represents a very considerable improvement compared with earlier modeling work, adding credibility to model-based studies of early Paleogene sensitivity. Fig.…”

“…Tropical sea surface temperatures (SSTs), previously thought to be similar to or even cooler than modern SSTs, were 3-10°C warmer than today (8)(9)(10)(11)(12), although uncertainty on these values remains large (13). Extratropical surface temperatures were 10-40°C warmer than modern extratropical surface temperatures in continental interiors (14)(15)(16)(17)(18), along polar margins (19,20), and over the oceans (21). Here, we compile these proxy interpretations to estimate that the global area-weighted annual mean surface temperature (MAT) in the early Eocene, the warmest part of the early Paleogene, was some 13 ± 2.6°C warmer than modern temperatures ( Fig.…”

“…On the other hand, some drops in crocodylomorph diversity correspond to temperature declines such as that of the Callovian affecting thalattosuchian diversity or the Valanginian-Hauterivian boundary affecting metriorhynchoids. Concerning the extinction of Pholidosauridae in the Turonian and Dyrosauridae in the Ypresian, a clear match between SST and diversity is absent, even when considering finescale SST variations reconstructed using other proxies 18,19 . Among the considered marine crocodylomorph lineages, the metriorhynchoids clearly stand out with an explosive radiation at the end of the Jurassic, when SSTs continued to decrease.…”

“…Schmitz et al, 2001;Schmitz and Pujalte, 2003). In fact, palaeosoil data from northern Spain (Schmitz and Pujalte, 2003) and terrestrial n-alkane δD records from eastern Tanzania (Handley et al, 2012) point to more arid annual conditions in the subtropics during the PETM. This is consistent with model predictions that warmer atmospheric temperatures will cause a stronger latitudinal evaporation-precipitation gradient, with higher evaporation rates in the sub-tropics and higher precipitation rates in mid-and high-latitudes (Manabe, 1996).…”

“…So far, TEX86 palaeothermometry has been applied to a limited number of PETM sections (Hollis et al, 2012;Sluijs et al, 2006Sluijs et al, , 2007Sluijs et al, , 2011Sluijs et al, , 2014Zachos et al, 2006) covering only a few locations worldwide, whereas a PETM MAT record based on the MBT/CBT proxy is available only for a single site located in the Arctic Ocean (Weijers et al, 2007a). The temperature records based on TEX86 show a similar extent of warming as those recorded by Mg/Ca and δ 18 O of foraminifera, i.e.…”
