A control simulation of the GFDL CM2.1 global coupled GCM, run for 2000 years with its atmospheric composition, solar irradiance, and land cover held fixed at 1860 values, exhibits strong interdecadal and intercentennial modulation of its ENSO behavior. To the extent that such modulation is realistic, it could attach large uncertainties to ENSO metrics diagnosed from centennial and shorter records – with important implications for historical and paleo records, climate projections, and model…

Stability of ENSO and Its Tropical Pacific Teleconnections over the Last Millennium
Abstract. Determining past changes in the amplitude, frequency and teleconnections of the El Nino-Southern Oscillation (ENSO) is important for understanding its potential sensitivity to future…

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 previous…
Analysis of ENSO’s response to unforced variability and anthropogenic forcing using CESM
TLDR
Comparisons of anthropogenic climate change with the effects of natural modulations in ENSO sea surface temperature (SST) metrics, as well as how internal variability may change with global warming, show the importance of careful assessment of ocean-atmosphere internal variability in E NSO projections.
High-resolution marine data and transient simulations support orbital forcing of ENSO amplitude since the mid-Holocene
Understanding Multidecadal Variability in ENSO Amplitude
AbstractSea surface temperatures (SSTs) in the tropical Pacific vary as a result of the coupling between ocean and atmosphere driven largely by El Nino–Southern Oscillation (ENSO). ENSO amplitude is…
Evolution and forcing mechanisms of El Niño over the past 21,000 years
TLDR
A series of transient Coupled General Circulation Model simulations forced by changes in greenhouse gasses, orbital forcing, the meltwater discharge and the ice-sheet history throughout the past 21,000 years show an orbitally induced strengthening of ENSO during the Holocene epoch.
ENSO Change in Climate Projections: Forced Response or Internal Variability?
Two large ensembles are used to quantify the extent to which internal variability can contribute to long‐term changes in El Niño‐Southern Oscillation (ENSO) characteristics. We diagnose changes that…
Significant changes to ENSO strength and impacts in the twenty‐first century: Results from CMIP5
Changes to the El Niño/Southern Oscillation (ENSO) and its atmospheric teleconnections under climate change are investigated using simulations conducted for the Coupled Model Intercomparison Project…
Evaluation of El Niño-Southern Oscillation in the ACCESS coupled model simulations for CMIP5
One of the key performance measures for Coupled General Circulation Models (CGCMs) is their ability to realistically simulate the prominent modes of climate variability. Here, we investigate the…

Variation of mean sea surface temperature and modulation of El Niño–Southern Oscillation variance during the past 150 years
Evidence is presented that the dominant non‐trend mode of interdecadal global SST variations is linked to significant modulation of ENSO variance during the past 150 years. The mode resembles the…
