Over periods of 2-8 years, after removing the overall trend of about 3 millimeters per year, the globally averaged sea-level rise closely follows the waxing and waning of El Niño. The main reason for this close match is that El Niño shifts rainfall from land to ocean, raising sea level. Its opposing phase, La Niña, shifts rainfall to land, causing sea level to drop.
