Much uncertainty surrounds the interactions between the El Niño–Southern Oscillation (ENSO) and long-term global change. Past periods of extreme global warmth, exemplified by the Eocene (55 to 35 million years ago), provide a good testing ground for theories for this interaction. Here, we compare Eocene coupled climate model simulations with annually resolved variability records preserved in lake sediments. The simulations show Pacific deep-ocean and high-latitude surface warming of ∼10°C but… Expand
Super El Niños in response to global warming in a climate model
Extraordinarily strong El Niño events, such as those of 1982/1983 and 1997/1998, cause havoc with weather around the world, adversely influence terrestrial and marine ecosystems in a number ofExpand
Cool La Niña During the Warmth of the Pliocene?
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.

ENSO as an Integrating Concept in Earth Science
Research to address many intertwined issues regarding ENSO dynamics, impacts, forecasting, and applications remain unresolved will lead to progress across a broad range of scientific disciplines and provide an opportunity to educate the public and policy makers about the importance of climate variability and change in the modern world.

A Review of Paleo El Niño-Southern Oscillation
The Earth has seen El Nino-Southern Oscillation (ENSO)—the leading mode of interannual climate variability—for at least millennia and likely over millions of years. This paper reviews previousExpand
Evidence for active El Nino Southern Oscillation variability in the Late Miocene greenhouse climate
An evaporite varve thickness record from the Late Miocene Mediterranean reveals significant signals of interannual variability, the frequency and persistence of which are compared with climaticExpand
El Niño in the Eocene greenhouse recorded by fossil bivalves and wood from Antarctica
[1] Quasi-periodic variation in sea-surface temperature, precipitation, and sea-level pressure in the equatorial Pacific known as the El Nino – Southern Oscillation (ENSO) is an important mode ofExpand
Implications of the permanent El Niño teleconnection "blueprint" for past global and North American hydroclimatology
Abstract. Substantial evidence exists for wetter-than-modern continental conditions in North America during the pre-Quaternary warm climate intervals. This is in apparent conflict with the robustExpand
Permanent El Niño and the onset of Northern Hemisphere glaciations: Mechanism and comparison with other hypotheses
[1] The tropical Pacific transitioned from a “permanent El Nino” state, that is, without the current equatorial zonal gradient of sea surface temperatures, to one with an equatorial cold tongue in aExpand
Cold tongue/Warm pool and ENSO dynamics in the Pliocene
Abstract. It has been suggested that a "permanent" El Nino climate state has existed in the warm Pliocene. One of the main pieces of evidence of such conditions is the small east-west sea surfaceExpand
Tropical ocean‐atmosphere controls on inter‐annual climate variability in the Cretaceous Arctic
[1] The first annually resolved sedimentary record from the Cretaceous is used to develop time series of inter-annual and decadal scale climate variability from the Arctic Ocean. Analysis of recordsExpand


Increased El Niño frequency in a climate model forced by future greenhouse warming
The El Niño/Southern Oscillation (ENSO) phenomenon is the strongest natural interannual climate fluctuation. ENSO originates in the tropical Pacific Ocean and has large effects on the ecology of theExpand
El Nino-like climate teleconnections in new england during the late pleistocene
The chronology shows a distinct interannual band of enhanced variability suggestive of El Nino-Southern Oscillation teleconnections into North America during the late Pleistocene, when the Laurentide ice sheet was near its maximum extent and climatic boundary conditions were different than those of today.

Suppression of El Niño during the Mid‐Holocene by changes in the Earth's orbit
A number of recent reports have interpreted paleoproxy data to describe the state of the tropical Pacific, especially changes in the behavior of the El Nino-Southern Oscillation (ENSO), over theExpand
The El Niño–Southern Oscillation in the Second Hadley Centre Coupled Model and Its Response to Greenhouse Warming
Abstract This paper describes El Nino–Southern Oscillation (ENSO) interannual variability simulated in the second Hadley Centre coupled model under “control” and “greenhouse warming” scenarios. TheExpand
ENSO variability, teleconnections and climate change
An overview is presented of the principal features of the El Nino-Southern Oscillation (ENSO) teleconnections in terms of regional patterns of surface temperature, precipitation and mid-troposphericExpand
El Niño: A coupled response to radiative heating?
The very existence of El Nino— the oscillatory behavior of the tropical Pacific climate—may be due to the warmth of the tropics (relative to the coldness of the high latitudes). This is elucidated byExpand
Is El Nino changing?
Apparent changes in the properties of El Nino could reflect the importance of random disturbances, but they could also be a consequence of decadal variations of the background state and the possibility that global warming is affecting those variations cannot be excluded. Expand

The possible influence of the El Nino/Southern Oscillation (ENSO) warm and cold extremes on mid-latitude circulation regimes in the North Atlantic/European sector is described in terms of aExpand
Climatic responses to tropical sea surface temperature changes on a “greenhouse” Earth
The uncertainty associated with tropical sea surface temperatures (SSTs) during past “greenhouse” climates may have important and unaccounted for effects. We explore early Paleogene climaticExpand
