In the past few decades, there have been various efforts made to extend, by means of proxy climate records, the relatively short instrumental record of the El Niño Southern Oscillation (ENSO) phenomenon. Most of these reconstructions are available at annual resolution (some with subdecadal timescales). Spatial and temporal changes in ENSO events have been documented and discussed in the literature, including changes in their secular variance structures in both the tropics and extratropical regions. These changes may affect the ability of proxy records to reproduce long‐term ENSO variability in the equatorial Pacific Ocean with high accuracy.
