    Last year’s increase was due to an unusual amount of ocean warming, combined with meltwater from land-based ice such as glaciers. 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 (0.59 centimeters) per year, compared…
