a–c Standard deviation of sea surface temperature anomalies (SSTA, in °C) in Geophysical Fluid Dynamics Laboratory (GFDL) paleoclimate model simulations. The significant standard deviation difference in Early Eocene Climatic Optimum (EECO) simulations relative to piControl at the 5% level is stippled based on F-test. d autocorrelation of Niño3.4 (5°S-5°N, 170°E-120°W) SSTA in GFDL piControl simulation, 1xCO2, and “land block” experiments.
