77 साल में ही समुद्र के बड़े हिस्से को समुद्र निगल लेगा. यूनिवर्सिटी ऑफ कैंटरबरी और यूनिवर्सिटी ऑफ मैरीलैंड के वैज्ञानिकों ने यह स्टडी की है.

साल 2100 तक अमेरिका में 90 लाख से लेकर 1.20 करोड़ लोग बढ़ते समुद्री जलस्तर से प्रभावित होंगे.

गाहे-बेगाहे आने वाले हाई-टाइडल फ्लड और समुद्री तूफानों की मात्रा बढ़ जाएगी.

इससे बड़े शहरों के तटीय इलाके या तो समुद्र में डूब जाएंगे. या फिर वो कटकर द्वीप बन जाएंगे.

पिछले साल नासा की स्टडी आई थी, जिसमें कहा गया था कि 2050 तक अमेरिका के लगभग सभी तट काफी हद तक डूब जाएंगे.

नासा की यह स्टडी 30 सालों के सैटेलाइट डेटा पर हुई थी. अमेरिकी तट 2050 तक एक फीट डूब जाएंगे.

सबसे बुरी हालत होगी गल्फ कोस्ट की. फिर दक्षिणपूर्व तटों की. यानी न्यूयॉर्क, सैन फ्रांसिस्को, लॉस एंजेल्स और वर्जीनिया जैसे तटीय राज्य.

अमेरिका के पूर्वी तट पर जलस्तर 10 से 14 इंच बढ़ेगा. खाड़ी तट पर 14 से 18 और पश्चिमी तट पर 4 से 8 इंच बढ़ेगा.

जितना ज्यादा ध्रुवीय बर्फ पिघलेगी, उतना ज्यादा जलस्तर बढ़ेगा. बर्फ ग्लोबल वॉर्मिंग से पिघल रही है.

अमेरिकी तटों को अल-नीनो और ला-नीना के प्रभावों का सामना 2030 के मध्य तक ज्यादा करना होगा.
