Global sea levels jumped due to El Nino and warming climate, says NASA

March 22, 2024

Global average sea level rose by about 0.3 inches (0.76 centimeters) from 2022 to 2023 -- nearly four times the increase of the previous year -- NASA said Thursday, attributing the "significant jump" to a strong El Nino and a warming climate. "Current rates of acceleration mean that we are on track to add another 20 centimetres of global mean sea level by 2050," said Nadya Vinogradova Shiffer, director for the NASA sea level change team and the ocean physics program in Washington. 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. El Nino involves warmer-than-average ocean temperatures in the equatorial Pacific. "Long-term datasets like this 30-year satellite record allow us to differentiate between short-term effects on sea level, like El Nino, and trends that let us know where sea level is heading," said Ben Hamlington, lead for NASA's sea level change team at JPL.
