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.

Earth’s oceans rose faster than expected last year as the world experienced its hottest year on record, NASA says.

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.

According to NASA's analysis, which uses satellite imagery to monitor rising water levels, the world's seas rose by 0.23-inch (0.59cm) last year—exceeding the previously predicted rise of 0.17-inch (0.43cm).

Communities in coastal areas such as Florida, shown in this 1992 NASA image, are vulnerable to the effects of sea level rise, including

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.
