دراسة تتنبأ بنهاية الحياة على كوكب الأرض.. وتكشف الموعد والسبب
1 سنة 0 1
صحيفة المرصد: تنبأ علماء من جامعة بريستول في المملكة المتحدة بنهاية الحياة على كوكب الأرض، مشيرين إلى اشتداد الظواهر المناخية المتطرفة سيؤدي إلى اندماج قارات العالم لتشكل قارة عملاقة واحدة، خلال حوالي 250 مليون سنة.


كوكب واحد
وبحسب الدراسة التي نشرت أمس الاثنين في مجلة نيتشر لعلوم الأرض : فإن "القارة العملاقة الجديدة، التي تسمى "بانجيا ألتيما"، لن يكون في الغالب على سطحها أي من البشر أو الثدييات، حيث وجد القائمون عليها أن الجو سيكون حارا للغاية وجافا وغير صالح للسكن تقريبا".


بيئة خالية من الغذاء

وقال كبير الباحثين المشاركين في الدراسة، ألكسندر فارنسورث، إن "البشر سوف يموتون، بسبب درجة الحرارة المتزايدة التي ستخلق بيئة خالية من الغذاء أو مصادر المياه للثدييات"، بحسب ما نقلت شبكة "سي أن أن".


المناخ
وأضافت يونيس لو، المؤلفة المشاركة والباحثة في تغير المناخ بجامعة بريستول: "بينما نتوقع أن يكون الكوكب غير صالح للسكن بعد 250 مليون سنة، فإننا نشهد اليوم بالفعل حرارة شديدة تضر بصحة الإنسان. لهذا السبب من المهم الوصول إلى صافي انبعاثات صفرية في أقرب وقت ممكن".
