Sea levels jump due to El Niño and climate change

By Ninian Carter

March 22, 2024 - Global average sea levels rose by about 0.76cm from 2022 to 2023, a larger than normal increase due mostly to a warming climate and the effects of a strong El Niño climate phenomenon.

A NASA-led analysis, based on 30 years of satellite observations beginning in the early 1990s, shows that sea levels have risen by some 9.4cm (4in) since 1993.

The rate of increase has also accelerated, more than doubling from 0.18cm (0.07in) per year in 1993 to the current pace of 0.42cm (0.17in) per year.

At the current rate of acceleration, the world is on track to add another 20cm (7.9in) to global mean sea levels by 2050 – creating a future where flooding will be far more frequent and negatively impactful than today.

From 2022 to 2023, NASA recorded a rise in sea levels of 0.76cm (0.3in) – a significant jump attributed to overall climate change and the effects of the El Niño climate phenomenon.

El Niño brings additional warmth to much of the tropics and subtropics, typically occurring every two to seven years with varying degrees of intensity.
