Any assessment of future climate change requires knowledge of the full range of natural variability in the El Niño/Southern Oscillation (ENSO) phenomenon. Here we splice together fossil-coral oxygen isotopic records from Palmyra Island in the tropical Pacific Ocean to provide 30–150-year windows of tropical Pacific climate variability within the last 1,100 years. The records indicate mean climate conditions in the central tropical Pacific ranging from relatively cool and dry during the tenth… 
Enhanced El Niño–Southern Oscillation Variability in Recent Decades
The El Niño–Southern Oscillation (ENSO) represents the largest source of year‐to‐year global climate variability. While Earth system models suggest a range of possible shifts in ENSO properties under
El Niño–Southern Oscillation and internal sea surface temperature variability in the tropical Indian Ocean since 1675
Abstract. The dominant modes of climate variability on interannual timescales in the tropical Indian Ocean are the El Nino–Southern Oscillation (ENSO) and the Indian Ocean Dipole. El Nino events have

Robust ENSO across a Wide Range of Climates
AbstractEl Nino–Southern Oscillation (ENSO) is a pronounced mode of climate variability that originates in the tropical Pacific and affects weather patterns worldwide. Growing evidence suggests that
El Niño–Southern Oscillation extrema in the Holocene and Last Glacial Maximum
[1] The El Nino–Southern Oscillation (ENSO) is the largest engine of interannual climate variability on the planet, yet its past behavior and potential for future change are poorly understood and
El Niño-Southern Oscillation during the past 50 years : Reconstructions from a western Pacific coral
Atmospheric and oceanographic fluctuations across the tropical Pacific Ocean are partly a function of the phenomena known as the El Niño Southern Oscillation (ENSO), which is recognised as the
ENSO and interdecadal climate variability over the last century documented by geochemical records of two coral cores from the South West Pacific
Abstract. The south west Pacific is affected by climatic phenomena such as ENSO (El Nino Southern Oscillation) or the PDO (Pacific Decadal Oscillation). Near-monthly resolution calibrations of Sr/Ca,
ENSO and internal sea surface temperature variability in the tropical Indian Ocean since the Maunder Minimum
Abstract. The dominant modes of climate variability on interannual timescales in the tropical Indian Ocean are the El Nino Southern Oscillation (ENSO) and the Indian Ocean Dipole. El Nino events have
Reef-Based Reconstructions of Eastern Pacific Climate Variability
In the eastern tropical Pacific, large spatial gradients in climate conditions are associated with oceanic upwelling and the position of the Intertropical Convergence Zone (ITCZ). Dramatic shifts in
Coral record of reduced El Niño activity in the early 15th to middle 17th centuries
El Nino–Southern Oscillation (ENSO) powers global interannual climate variability through changes in trade wind strength, temperature and salinity anomalies, sea level, and atmospheric circulation


Influence of mean climate change on climate variability from a 155-year tropical Pacific coral record
The results suggest that variability in the tropical Pacific is linked to the region’s mean climate, and that changes in both have occurred during periods of natural as well as anthropogenic climate forcing.
Variability in the El Niño-Southern Oscillation Through a Glacial-Interglacial Cycle
Annual banded corals from Papua New Guinea are used to show that ENSO has existed for the past 130,000 years, operating even during “glacial” times of substantially reduced regional and global temperature and changed solar forcing, and it is found that during the 20th century ENGSO has been strong compared with E NSO of previous cool and warm times.
Recent Variability in the Southern Oscillation: Isotopic Results from a Tarawa Atoll Coral
Spectral analysis suggests that the distribution of variance in this record has shifted among annual to interannual periods during the present century, concurrent with observed changes in the strength of the Southern Oscillation.
El Niño during the Last Interglacial Period recorded by a fossil coral from Indonesia
Measurements of oxygen isotopes and elemental ratios in a fossil coral that grew 124,000 years ago in North Sulawesi, Indonesia, reflect interannual variability in precipitation and sea surface
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 the
Eight centuries of north atlantic ocean atmosphere variability
A high-resolution study of Caribbean sediments provides a subdecadally resolved record of tropical upwelling and trade wind variability spanning the past 825 years, confirming the importance of a decadal mode of Atlantic variability believed to be driven by coupled tropical ocean-atmosphere dynamics.
Rainfall and drought in equatorial east Africa during the past 1,100 years
A decade-scale reconstruction of rainfall and drought in equatorial east Africa over the past 1,100 years is presented, based on lake-level and salinity fluctuations of Lake Naivasha inferred from three different palaeolimnological proxies: sediment stratigraphy and the species compositions of fossil diatom and midge assemblages.
A central tropical Pacific coral demonstrates Pacific, Indian, and Atlantic decadal climate connections
While instrumental and proxy‐based climate records describe significant decadal‐scale climate variability throughout the tropical Pacific, Indian, and Atlantic Oceans, the processes responsible for
Southward Migration of the Intertropical Convergence Zone Through the Holocene
The Cariaco Basin record exhibits strong correlations with climate records from distant regions, including the high-latitude Northern Hemisphere, providing evidence for global teleconnections among regional climates.
