NASA data shows global sea levels are rising faster than expected. Most of the rise in 2024 came from ocean warming, not melting ice.

Global sea levels rose at an accelerated rate in 2024, driven by extreme ocean warming and melting land ice, according to a NASA-led analysis. The annual rate of sea level rise jumped to 0.23 inches (0.59 cm), significantly higher than the expected 0.17 inches (0.43 cm).

Sea levels surged in 2024, rising faster than expected due to warming oceans. Unlike previous years, where melting ice dominated, thermal expansion drove most of the increase. NASA's satellite records show sea levels climbing steadily since 1993,

The world's sea levels grew far more quickly and by a larger amount than anticipated in 2024, mostly due to warming water temperatures, a new NASA analysis shows.

Global sea levels rose more than expected in 2024, Earth's hottest year on record, according to an analysis released Thursday by the US space agency NASA.

Global sea levels rose by an unexpected amount in 2024, which was officially recorded as the hottest year on Earth since temperature monitoring began. According to a NASA analysis, the rise was primarily driven by unusual ocean warming and glacial meltwater,
