El hielo marino del Ártico llega a un mínimo récord

By Phil Bainbridge

March 28, 2025 - El hielo marino del Ártico alcanzó su extensión máxima anual el 22 de marzo, el nivel más bajo en el registro satelital de 47 años y 80.000km² por abajo del mínimo previo en 2017.

The maximum extent in 2025 was 14.33 million square kilometres, 1.31m sq km less than the average for the period 1981-2010, at 15.64m sq km. Sea ice was low throughout the Arctic, with the Gulf of St Lawrence - virtually ice free, and the Sea of Okhotsk particularly badly affected. Last year was the hottest year on record and the loss of Arctic ice threatens to accelerate positive feedback loops related to climate change.

Sea ice is typically at its maximum extent in March, followed by a slow melt over the spring and summer months, reaching its smallest area in September.
