Changes in ENSO variability during the mid-Holocene epoch (~6,000 years ago) have been the subject of a number of papers in the past fifteen years, but changes in the mean climate of the tropical Pacific have not received as much attention. Results from a coupled atmosphere-ocean model indicate that changes in the earth's orbital configuration during the mid-Holocene led to a reduction in the amplitude of the annual cycle of sea surface temperature in the eastern equatorial Pacific Ocean. The mechanisms underlying this change will be discussed along with implications for the interpretation of paleoclimatic data and the atmospheric circulation in distant regions.
