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

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,

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,
