Study: climate change appears to have stopped the next ice age

تحقیق: موسمیاتی تبدیلی نے اگلے برفانی دور کو روک دیا ہے

अध्ययन: जलवायु परिवर्तन ने अगले हिम युग को रोक दिया है

Study: climate change appears to have stopped the next ice age

Key points

اہم نکات

मुख्य बातें

  • A new study in the journal Science suggests the next ice age may have already begun about 2,000 years ago, only to be cut short by human-driven climate change.
  • Researchers studied the Barnes Ice Cap in Arctic Canada, the last remnant of the vast Laurentide Ice Sheet.
  • It began slowly expanding again around 2,000 years ago, but around 1960 rising summer temperatures reversed that growth.
  • جریدے سائنس میں شائع ہونے والی ایک نئی تحقیق کے مطابق اگلا برفانی دور تقریباً 2,000 سال پہلے شروع ہو چکا تھا، لیکن انسانوں کی وجہ سے موسمیاتی تبدیلی نے اسے روک دیا۔ محققین نے آرکٹک کینیڈا میں بارنز آئس کیپ کا مطالعہ کیا، جو وسیع لارینٹائیڈ آئس شیٹ کی آخری باقیات ہے۔ یہ تقریباً 2,000 سال پہلے دوبارہ آہستہ آہستہ پھیلنے لگی تھی، لیکن تقریباً 1960 میں گرمیوں کے درجہ حرارت بڑھنے سے یہ پھیلاؤ الٹ گیا۔ تب سے یہ سردیوں میں جتنی برف حاصل کرتی ہے، گرمیوں میں اس سے زیادہ کھو رہی ہے، اور سائنس دانوں کا کہنا ہے کہ یہ خوشی کی بات نہیں، کیونکہ یہی گرمی آرکٹک بھر میں برف کی ٹوپیوں کو پگھلا رہی ہے۔
  • जर्नल साइंस में प्रकाशित एक नए अध्ययन के अनुसार अगला हिम युग लगभग 2,000 साल पहले शुरू हो चुका था, लेकिन मानव-जनित जलवायु परिवर्तन ने उसे रोक दिया। शोधकर्ताओं ने आर्कटिक कनाडा में बार्न्स आइस कैप का अध्ययन किया, जो विशाल लॉरेंटाइड आइस शीट का अंतिम अवशेष है। यह लगभग 2,000 साल पहले फिर से धीरे-धीरे फैलने लगी थी, लेकिन लगभग 1960 में गर्मियों के तापमान बढ़ने से यह फैलाव उलट गया। तब से यह सर्दियों में जितनी बर्फ़ पाती है, गर्मियों में उससे ज़्यादा खो रही है, और वैज्ञानिकों का कहना है कि यह खुशी की बात नहीं है, क्योंकि यही गर्मी आर्कटिक भर में बर्फ़ की टोपियों को पिघला रही है।

A new study in the journal Science suggests the next ice age may have already begun about 2,000 years ago, only to be cut short by human-driven climate change. Researchers studied the Barnes Ice Cap in Arctic Canada, the last remnant of the vast Laurentide Ice Sheet. It began slowly expanding again around 2,000 years ago, but around 1960 rising summer temperatures reversed that growth. Since then it has been losing more ice in summer than it regains in winter, and scientists say this is no reason to celebrate, as the same warming is melting ice caps across the Arctic.
