A tropical Pacific climate state resembling that of a permanent El Niño is hypothesized to have ended as a result of a reorganization of the ocean heat budget ∼3 million years ago, a time when large ice sheets appeared in the high latitudes of the Northern Hemisphere. We report a high-resolution alkenone reconstruction of conditions in the heart of the eastern equatorial Pacific (EEP) cold tongue that reflects the combined influences of changes in the equatorial thermocline, the properties of… 
Subpolar Link to the Emergence of the Modern Equatorial Pacific Cold Tongue
TLDR
It is found that the sub-Antarctic and sub-Arctic regions underwent substantial cooling nearly synchronous to the cold tongue development, thereby providing support for the hypothesis that extratropical cooling drove the development of the modern cold tongue during the Pliocene-Pleistocene transition.
Sea ice control of Plio-Pleistocene tropical Pacific climate evolution
The Pliocene Paradox (Mechanisms for a Permanent El Niño)
TLDR
A future melting of glaciers, changes in the hydrological cycle, and a deepening of the thermocline could restore the warm conditions of the early Pliocene.
Astronomically modulated late Pliocene equatorial Pacific climate transition and Northern Hemisphere ice sheet expansion
The equatorial Pacific underwent a significant climate transition during the late Pliocene, which is characterized by cooling of global sea surface temperatures (SSTs) and formation of a marked SST

The late Pliocene is marked by the end of an interval of warm, relatively stable global climate and a secular shift into a bipolar glaciated world. The intensification of northern hemisphere
Pliocene decoupling of equatorial Pacific temperature and pH gradients.
TLDR
These results provide a mechanism for enhanced productivity in the early Pliocene/late Miocene east Pacific even in the presence of weaker wind-driven upwelling, and shed new light on equatorial Pacific dynamics.
Decoupling of temperature and pH gradients along the equatorial Pacific during the Pliocene
Equatorial Pacific dynamics drive tropical climate patterns such as the El Niño-Southern Oscillation and provide nutrients for one of the world’s most productive marine ecosystems. How this region

Stable sea surface temperatures in the western Pacific warm pool over the past 1.75 million years
TLDR
High-resolution records of sea surface temperatures spanning the past 1.75 million years are presented and it is inferred that the temperature contrast across the equatorial Pacific Ocean increased, which might have had a significant influence on the mid-Pleistocene climate transition.
Regional climate shifts caused by gradual global cooling in the Pliocene epoch
TLDR
Climate records from high latitudes, subtropical regions and the tropics are compared, indicating that the onset of large glacial/interglacial cycles did not coincide with a specific climate reorganization event at lower latitudes and suggesting that mean low-latitude climate conditions can significantly influence global climate feedbacks.
High-latitude influence on the eastern equatorial Pacific climate in the early Pleistocene epoch
TLDR
It is concluded that during the early Pleistocene epoch, climate variability at the study site must have been determined by high-latitude processes that were driven by orbital obliquity forcing.
The Mid-Pleistocene Transition in the Tropical Pacific
TLDR
The timing and nature of tropical Pacific SST changes over the mid-Pleistocene transition implicate a shift in the periodicity of radiative forcing by atmospheric carbon dioxide as the cause of the switch in climate periodicities at this time.

Cool La Niña During the Warmth of the Pliocene?
TLDR
The Pliocene paleothermometer supports the idea of a dynamic “ocean thermostat” in which heating of the tropical Pacific leads to a cooling of the east equatorial Pacific and a La Niña–like state, analogous to observations of a transient increasing east-west sea surface temperature gradient in the 20th-century tropical Pacific.
