ذوبان الجليد.. أضرار تستمر قرونا

ما يعرفه ريفو عن الخبر

سيؤدي تجاوز التدفئة العالمية حاجز 1.5 درجة مئوية إلى أضرار جسيمة في المساحات الجليدية تمتد لعدة أجيال.
لن تتمكن المساحات الجليدية المفقودة من التعافي بالسرعة ذاتها حتى لو انخفضت درجات حرارة الأرض مستقبلا.
يؤدي تراجع الصفائح الجليدية إلى ارتفاع مستوى البحر عدة أمتار، مما يهدد المجتمعات الساحلية والبنية التحتية.
يتسبب تراجع الأنهار الجليدية في المناطق الجبلية بمخاطر على إمدادات المياه والفيضانات والانهيارات الصخرية.

ويحذر التقرير من أن حجم الخسائر يرتبط بأقصى مستوى يبلغه الاحترار، والمدة التي يبقى خلالها فوق عتبة 1.5 درجة مئوية مقارنة بمستويات ما قبل الثورة الصناعية.
