From: South Pacific sea surface temperature and global ocean circulation changes since the late Miocene

Fig. 2

Temporal variation of a the global ocean benthic δ18O reflecting global temperature36, b global mean surface temperature difference from today (GMST)2, c temperature difference from today in Southern Hemisphere extratropics2 and d the alkenone-based sea surface temperature in the Eastern South Pacific (ESP) Ocean (SSTUK’37; U1543/PS97-114-2; this study). The thick smoothed SSTUK’37 record represents a 100 kyr-binned record by averaging the SSTUK’37 data for every 100 kyrs in 50 kyr-overlapping windows. LMC late Miocene cooling, PTR Pliocene global temperature reversal, PWP Pliocene warm period, iNHG intensification of the Northern Hemisphere Glaciation, MPT mid-Pleistocene transition.
