Between 1901 and 2018, average global sea level rose by 15–25 cm (6–10 in), an average of 1–2 mm (0.039–0.079 in) per year.[2] This rate accelerated to 4.62 mm (0.182 in)/yr for the decade 2013–2022.[3] Climate change due to human activities is the main cause.[4]: 5, 8  Between 1993 and 2018, thermal expansion of water accounted for 42% of sea level rise. Melting temperate glaciers accounted for 21%, while polar glaciers in Greenland accounted for 15% and those in Antarctica for 8%.[5]: 1576
