جليد بحر القطب الشمالي يصل إلى أدنى مستوى له في الشتاء

By Phil Bainbridge

March 28, 2025 - بلغ جليد بحر القطب الشمالي أقصى امتداد سنوي له في 22 آذار (مارس)، وهو أدنى مستوى له في سجل الأقمار الصناعية الذي ابتدأ منذ 47 عاماً، وأصغر بمقدار 80.000 كيلومتر مربع من أدنى مستوى سابق سُجِّل في العام 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.
