Last year’s rate of average global sea level rise was 0.23 inches per year, higher than the expected 0.17 inches per year, NASA found. The rise follows are trend of rapidly increasing rates over the past 30 years.

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 level rose faster than expected in 2024, mostly because of ocean water expanding as it warms, or thermal expansion. According to a NASA-led analysis, last year's rate of rise was 0.23 inches (0.

Last year saw an “unexpected” amount of sea level rise around the world, the National Aeronautics and Space Administration said Thursday. An analysis led by the agency found that the rate of rise was nearly a quarter of an inch per year, compared to an expected rate of 0.17 inches.

It is well known that sea levels are rising worldwide as a result of climate change. Last year, however, the increase was unexpectedly large, according to NASA.

Sea levels rose even higher than anticipated last year, according to an analysis by NASA. Last year was the hottest on record for the planet — largely due to human-caused climate change — leading to a sea-level rise of nearly 0.
