Hidden Arctic roots could decide the region's climate future, review finds

جائزہ: آرکٹک کی چھپی جڑیں خطے کے موسمی مستقبل کا فیصلہ کر سکتی ہیں

समीक्षा: आर्कटिक की छिपी जड़ें क्षेत्र के जलवायु भविष्य का फैसला कर सकती हैं

Hidden Arctic roots could decide the region's climate future, review finds

Key points

اہم نکات

मुख्य बातें

  • A major international review has found that plant roots beneath the Arctic tundra could play a decisive role in whether the region becomes a source or a sink of carbon as the climate warms.
  • Arctic permafrost holds around 1,460 to 1,600 billion tonnes of organic carbon, roughly twice the amount in the atmosphere, and thawing ground is already releasing some of it.
  • Roots can lock carbon into soil by supporting plant growth, but they can also stimulate microbes that release carbon dioxide and methane.
  • ایک بڑے بین الاقوامی جائزے میں پایا گیا ہے کہ آرکٹک ٹنڈرا کے نیچے پودوں کی جڑیں اس بات میں فیصلہ کن کردار ادا کر سکتی ہیں کہ موسم گرم ہونے پر یہ خطہ کاربن کا ذریعہ بنے گا یا اسے جذب کرنے والا۔ آرکٹک کی منجمد زمین میں تقریباً 1460 سے 1600 ارب ٹن نامیاتی کاربن موجود ہے، جو فضا میں موجود مقدار سے تقریباً دوگنا ہے، اور پگھلتی زمین پہلے ہی اس کا کچھ حصہ خارج کر رہی ہے۔ جڑیں پودوں کی نشوونما میں مدد دے کر کاربن کو مٹی میں بند کر سکتی ہیں، لیکن وہ ان جراثیم کو بھی متحرک کر سکتی ہیں جو کاربن ڈائی آکسائیڈ اور میتھین خارج کرتے ہیں۔ محققین کا کہنا ہے کہ موسمی ماڈلز کو ان زیر زمین عمل کو بہتر طور پر سمجھنا ہوگا تاکہ یہ پیش گوئی ہو سکے کہ گرمی تیز ہوگی یا سست۔
  • एक बड़े अंतरराष्ट्रीय समीक्षा में पाया गया है कि आर्कटिक टुंड्रा के नीचे पौधों की जड़ें इस बात में निर्णायक भूमिका निभा सकती हैं कि जलवायु गर्म होने पर यह क्षेत्र कार्बन का स्रोत बनेगा या उसे सोखने वाला। आर्कटिक की जमी हुई ज़मीन में लगभग 1,460 से 1,600 अरब टन जैविक कार्बन मौजूद है, जो वायुमंडल में मौजूद मात्रा से लगभग दोगुना है, और पिघलती ज़मीन पहले ही इसका कुछ हिस्सा छोड़ रही है। जड़ें पौधों की वृद्धि में मदद देकर कार्बन को मिट्टी में बंद कर सकती हैं, लेकिन वे उन सूक्ष्मजीवों को भी सक्रिय कर सकती हैं जो कार्बन डाइऑक्साइड और मीथेन छोड़ते हैं। शोधकर्ताओं का कहना है कि जलवायु मॉडलों को इन भूमिगत प्रक्रियाओं को बेहतर ढंग से समझना होगा ताकि यह अनुमान लगाया जा सके कि गर्मी तेज़ होगी या धीमी।

A major international review has found that plant roots beneath the Arctic tundra could play a decisive role in whether the region becomes a source or a sink of carbon as the climate warms. Arctic permafrost holds around 1,460 to 1,600 billion tonnes of organic carbon, roughly twice the amount in the atmosphere, and thawing ground is already releasing some of it. Roots can lock carbon into soil by supporting plant growth, but they can also stimulate microbes that release carbon dioxide and methane. The researchers say climate models must better capture these underground processes to predict whether warming will speed up or slow down.
