Overall, sea levels have risen by around four inches since 1993. The rate of increase has also accelerated, more than doubling from 0.07 inches per year in 1993, to the current rate of 0.17 inches per year. The immediate cause of the spike is the El Nino weather effect, which replaced the La Nina from 2021 to 2022, when the sea level rose around 0.08 inches.“In El Nino years, a lot of the rain that normally falls on land ends up in the ocean, which raises sea levels temporarily,” said Josh Willis, a sea level researcher at Nasa’s Jet Propulsion Laboratory .
