(رصيد الصورة: تصوير جوليا ماركس بيترسون، كولدكس) استخرج العلماء قطعة جليد عمرها 6 ملايين سنة من القارة القطبية الجنوبية - وهي أقدم جليد تم اكتشافه بشكل مباشر على الإطلاق - وهي تساعدهم على إعادة بناء مناخ الأرض القديم. يبلغ عمر الجليد الذي حطم الرقم القياسي، إلى جانب فقاعات الهواء المحبوسة بداخله، أكثر من ضعف عمر أقدم عينات الجليد المعروفة سابقًا، والتي يبلغ عمرها حوالي 2.7 مليون سنة، وفقًا لدراسة جديدة نُشرت في 28 أكتوبر في المجلة.
