D\u00fcnya Buzul \u0130zleme Servisi Y\u00f6neticisi Michael Zemp’in Nature mecmuas\u0131nda yay\u0131mlad\u0131\u011f\u0131 yeni \u00e7al\u0131\u015fmaya nazaran, son on y\u0131lda buzullar\u0131n erime oran\u0131, 2000-2011 periyoduna k\u0131yasla k\u0131ymetli \u00f6l\u00e7\u00fcde artm\u0131\u015f durumda. Bu \u00e7al\u0131\u015fma, 35 farkl\u0131 bilimsel grubun 230’dan fazla b\u00f6lgesel kestirim raporunun birle\u015ftirilmesiyle yap\u0131ld\u0131 ve buzullar\u0131n erime surat\u0131n\u0131n gezegenin gelece\u011fi \u00fczerinde yarataca\u011f\u0131 tesirler hakk\u0131nda kritik datalar sunuyor.<\/p>\n
Tatl\u0131 Su Kaynaklar\u0131 Tehdit Alt\u0131nda<\/b><\/p>\n
Buzullar, bilhassa tatl\u0131 su kaynaklar\u0131 a\u00e7\u0131s\u0131ndan b\u00fcy\u00fck ehemmiyet ta\u015f\u0131yor. Lakin ara\u015ft\u0131rma, da\u011f buzullar\u0131n\u0131n s\u00fcratle k\u00fc\u00e7\u00fcld\u00fc\u011f\u00fcn\u00fc ve son 25 y\u0131lda buzul alanlar\u0131n\u0131n y\u00fczde 5 oran\u0131nda azald\u0131\u011f\u0131n\u0131 belirtiyor. Ola\u011fan \u015fartlarda, buzullar kar ya\u011f\u0131\u015f\u0131 ile eriyen k\u00fctlelerini telafi ederek dengeyi sa\u011flar. Ama artan fosil yak\u0131t kullan\u0131m\u0131 ve global s\u0131cakl\u0131klar\u0131n y\u00fckselmesi bu dengeyi bozdu.<\/p>\n
B\u00fcy\u00fck Kay\u0131plar ve \u00c7arp\u0131c\u0131 Veriler<\/b><\/p>\n
\u00c7al\u0131\u015fmaya nazaran, 2000-2023 y\u0131llar\u0131 ortas\u0131nda Gr\u00f6nland ve Antarktika\u2019daki buzullar, y\u0131lda ortalama 270 milyar ton buz kaybetti. Zemp, bu kayb\u0131 daha somut hale getirmek i\u00e7in \u015fu \u00f6rne\u011fi verdi: “Her ki\u015fi i\u00e7in g\u00fcnde 3 litre su olmak \u00fczere t\u00fcm d\u00fcnya n\u00fcfusunun 30 y\u0131ll\u0131k su t\u00fcketimine denk geliyor.”<\/p>\n
Erime Oran\u0131 Dramatikle\u015fiyor<\/b><\/p>\n
Baz\u0131 b\u00f6lgelerde buzul erimesi dramatik boyutlara ula\u015ft\u0131. Bilhassa Avrupa’n\u0131n orta k\u0131s\u0131mlar\u0131nda, son 20 y\u0131lda buzullar\u0131n y\u00fczde 39’unun kayboldu\u011fu tespit edildi. Bu, buzul alanlar\u0131nda ya\u015fanan b\u00fcy\u00fck kay\u0131plar\u0131n bir \u00f6b\u00fcr \u00f6rne\u011fi olarak dikkat \u00e7ekiyor.<\/p>\n
