134 مليار طن من الجليد الساحلي تذوب خلال عقد واحد!

ما يعرفه ريفو عن الخبر

فقدت الأنهار الجليدية الساحلية والبحيرية نحو 134 مليار طن من الجليد خلال عقد واحد بسبب الاحتباس الحراري.
تتحرك الأنهار الجليدية الساحلية بسرعة أكبر بنسبة 44% مقارنة بالأنهار البرية مما يسرع من ذوبانها.
تعد مناطق القطب الشمالي الروسي وأيسلندا والدول الإسكندنافية وجبال الأنديز الأكثر تضرراً من فقدان الجليد الساحلي.
حذرت الأمم المتحدة من أن الانحسار السريع للأنهار الجليدية يهدد إمدادات الغذاء والماء لأكثر من ملياري شخص.

اكتشف العلماء أن الجليد الساحلي (يشكل 3 بالمئة من إجمالي كتلة الجليد على الأرض) فقد حوالي 134 مليار طن من الماء خلال العقد الماضي، أي 57 بالمئة من إجمالي فقدان كتل الجليدي العالمي.
