Extended Data Fig. 4: The reconstructed Holocene evolution of ENSO amplitude.
From: Increased frequency of multi-year El Niño–Southern Oscillation events across the Holocene
The Holocene evolution of ENSO amplitude from the reconstruction synthesis, as indicated by the standard deviation of δ18O anomalies (subtracting seasonal cycle) from each Central Pacific coral slice longer than 20-years. The blue dashed line is weighted (by data length) linear fit.
