Kar ve buzullar\u0131n olu\u015fturdu\u011fu barajlar\u0131n patlamas\u0131, ABD\u2019de \u00e7ok bilinmiyor. Juneau\u2019da, ya\u011fmur ve eriyen karlarla olu\u015fan ve baraj vazifesi g\u00f6ren Mendenhall Buzulu\u2019nun da bulundu\u011fu havzan\u0131n yak\u0131n\u0131nda sel meydana geldi.<\/p>\n
Havzadan akan su, 2011\u2019den bu yana aral\u0131klarla sele neden oluyor. Alaska G\u00fcneydo\u011fu \u00dcniversitesi\u2019nde \u00e7evre bilimi alan\u0131nda profes\u00f6r Eran Hood, normalde suyun daha yava\u015f ve g\u00fcnlerce akt\u0131\u011f\u0131n\u0131 ifade etti.<\/p>\n
\u00d6te yandan hafta sonu meydana gelen olay, suyun \u00e7ok daha \u00e7abuk y\u00fckselmesi nedeniyle hayret verici olarak g\u00f6r\u00fcl\u00fcyor. Hood, ak\u0131nt\u0131n\u0131n nehrin kald\u0131rabilece\u011finin de \u00f6tesinde oldu\u011funu vurgulad\u0131.<\/p>\n
Hood, Mendenhall Nehri\u2019nin zemininin daha gev\u015fek buzul katmanlar\u0131ndan olu\u015ftu\u011funu ve bu nedenle a\u015f\u0131nmas\u0131n\u0131n daha kolay oldu\u011funu belirterek, \u015fiddetli ya\u011fmurlar\u0131n ya\u011fd\u0131\u011f\u0131 bir d\u00f6neme denk gelmesi durumunda selin daha da y\u0131k\u0131c\u0131 olabilece\u011fini s\u00f6yledi.<\/p>\n
Bilim insanlar\u0131, iklim de\u011fi\u015fikli\u011fi, Mendenhall ve d\u00fcnyadaki di\u011fer buzullar\u0131 eritirken, bunun seller ile ba\u011flant\u0131s\u0131n\u0131n karma\u015f\u0131k oldu\u011funu dile getiriyor.<\/p>\n
Calgary \u00dcniversitesinden \u00e7evresel deprem bilimi uzman\u0131 Celeste Labedz, zamanlama ve yo\u011funlu\u011fun de\u011fi\u015fkenlik g\u00f6stermesinin, bu t\u00fcr sellere haz\u0131rlanmay\u0131 zorla\u015ft\u0131rd\u0131\u011f\u0131n\u0131 dile getirdi.
Nature Communications taraf\u0131ndan bu y\u0131l yay\u0131mlanan \u00e7al\u0131\u015fmaya g\u00f6re, yaln\u0131zca Hindistan, Pakistan, Peru ve \u00c7in\u2019de insanlar\u0131n yar\u0131s\u0131 buzullardan kaynaklanabilecek sellerden dolay\u0131 risk alt\u0131nda.<\/p>\n
Bu ba\u011flamda ara\u015ft\u0131rmac\u0131lar, buzullar\u0131n neden oldu\u011fu sellerin d\u00fcnyada 15 milyon ki\u015fiyi tehdit edebilece\u011fine i\u015faret ediyor. (AA)<\/p>\n","protected":false},"excerpt":{"rendered":"
