Alaska Buzullar\u0131n\u0131n Yok Olu\u015fu: Bir Y\u00fczy\u0131ll\u0131k De\u011fi\u015fim<\/h2>\n\n

Buzul Gerilemesinin Tarihsel Belgeleri<\/h2>\n\n

ABD Jeoloji Ara\u015ft\u0131rmalar\u0131 Kurumu’ndan jeolog Bruce Molnia, onlarca y\u0131l boyunca Alaska buzullar\u0131n\u0131n tarihi foto\u011fraflar\u0131n\u0131 toplad\u0131 ve inceledi. Bu foto\u011fraflar, k\u00fcresel \u0131s\u0131nma nedeniyle son y\u00fczy\u0131lda meydana gelen dramatik de\u011fi\u015fimlere dair e\u015fsiz bir bak\u0131\u015f a\u00e7\u0131s\u0131 sunuyor.<\/p>\n\n

Molnia’n\u0131n \u00f6nce-sonra foto\u011fraflar\u0131, Glacier Bay Ulusal Park\u0131, Denali ve Kenai Fiyortlar\u0131 Ulusal Parklar\u0131 ile Chugach Ulusal Orman\u0131’ndaki eriyen buzullara dair inand\u0131r\u0131c\u0131 kan\u0131tlar sunuyor. Orijinal foto\u011fraflar\u0131n \u00e7ekildi\u011fi yerleri tam olarak yeniden ziyaret ederek Molnia, bir zamanlar y\u00fckselen buz devleri ile g\u00fcn\u00fcm\u00fcz\u00fcn gerileyen buzullar\u0131 aras\u0131ndaki keskin tezat\u0131 yakalad\u0131.<\/p>\n\n

K\u00fcresel Is\u0131nman\u0131n Alaska Buzullar\u0131 \u00dczerindeki Etkileri<\/h2>\n\n

Son 75 ila 100 y\u0131lda Alaska’daki ortalama y\u0131ll\u0131k s\u0131cakl\u0131klar yakla\u015f\u0131k 5 derece Fahrenheit artt\u0131 ve bu da buzullar\u0131n \u00f6nemli \u00f6l\u00e7\u00fcde geri \u00e7ekilmesine neden oldu. Molnia taraf\u0131ndan incelenen buzullar\u0131n yaln\u0131zca %1 ila 2’si muhtemelen y\u00fcksek rak\u0131mlarda artan kar ya\u011f\u0131\u015f\u0131 nedeniyle b\u00fcy\u00fcd\u00fc. B\u00fcy\u00fck \u00e7o\u011funluk g\u00f6zle g\u00f6r\u00fcl\u00fcr \u015fekilde k\u00fc\u00e7\u00fcl\u00fcyor ve baz\u0131lar\u0131 son 95 y\u0131lda uzunluklar\u0131n\u0131n 20 mile kadar\u0131n\u0131 kaybetti.<\/p>\n\n

Bu buzul erimesi Alaska’n\u0131n \u00e7evresi ve altyap\u0131s\u0131 i\u00e7in ciddi sonu\u00e7lara yol a\u00e7\u0131yor. H\u00fck\u00fcmet Sorumluluk Ofisi’nin 2003 y\u0131l\u0131nda yapt\u0131\u011f\u0131 bir \u00e7al\u0131\u015fma, Alaska k\u00f6ylerinin %86’s\u0131n\u0131n eriyen buzullar ve deniz buzu nedeniyle sel ve erozyon tehdidi alt\u0131nda oldu\u011funu ortaya koydu.<\/p>\n\n

Buzul Erimesinin K\u00fcresel Kapsam\u0131<\/h2>\n\n

Buzullar\u0131n azalmas\u0131 sadece Alaska ile s\u0131n\u0131rl\u0131 de\u011fil. Buzullar, Arctic National Wildlife Refuge, Antarktika ve \u00c7in, Peru ve Arjantin’deki da\u011f zirveleri de dahil olmak \u00fczere hemen hemen her yerde k\u00fc\u00e7\u00fcl\u00fcyor. Hatta Kilimanjaro Da\u011f\u0131’n\u0131n ikonik buzullar\u0131 bile h\u0131zla eriyor.<\/p>\n\n

Ohio State \u00dcniversitesi’nden glasiyolog Lonnie Thompson, mevcut e\u011filim devam ederse Montana-Kanada s\u0131n\u0131r\u0131ndaki Glacier Ulusal Park\u0131’n\u0131n 30 y\u0131l i\u00e7inde t\u00fcm buzullar\u0131n\u0131 kaybedece\u011fini \u00f6ng\u00f6r\u00fcyor.<\/p>\n\n

Buzul Erimesinin Do\u011fal ve \u0130nsan Kaynakl\u0131 Nedenleri<\/h2>\n\n

D\u00fcnya iklimindeki do\u011fal de\u011fi\u015fiklikler buz \u00e7a\u011flar\u0131n\u0131n gelip ge\u00e7mesine neden olsa da bilim insanlar\u0131, atmosferdeki karbondioksit seviyelerindeki son ani art\u0131\u015f\u0131n buzul erimesini \u00f6nemli \u00f6l\u00e7\u00fcde h\u0131zland\u0131rd\u0131\u011f\u0131 konusunda hemfikir. Karbondioksit, sera etkisine yol a\u00e7arak atmosferde \u0131s\u0131y\u0131 hapseder.<\/p>\n\n

Fosil yak\u0131tlar\u0131n yak\u0131lmas\u0131 gibi insan faaliyetleri, havaya b\u00fcy\u00fck miktarlarda karbondioksit salmaktad\u0131r. Bu sera gazlar\u0131n\u0131n birikmesi k\u00fcresel \u0131s\u0131nman\u0131n etkilerini \u015fiddetlendirmekte ve buzullar\u0131n h\u0131zla erimesine neden olmaktad\u0131r.<\/p>\n\n

Buzul Erimesinin Bilimi<\/h2>\n\n

Buzullar, zamanla kar\u0131n birikmesi ve s\u0131k\u0131\u015fmas\u0131yla olu\u015fur. Kar\u0131n a\u011f\u0131rl\u0131\u011f\u0131, pullar\u0131 insan ba\u015f\u0131 kadar b\u00fcy\u00fcyebilen buz kristallerine s\u0131k\u0131\u015ft\u0131r\u0131r.<\/p>\n\n

I\u015f\u0131k s\u0131k\u0131\u015ft\u0131r\u0131lm\u0131\u015f buza n\u00fcfuz etti\u011finde, k\u0131rm\u0131z\u0131 dalga boylar\u0131 emilir ve \u00fcrk\u00fct\u00fcc\u00fc bir mavi \u0131\u015f\u0131lt\u0131 b\u0131rak\u0131r. Bu buzul mavisi, yar\u0131klar\u0131n dibinde veya buzullar\u0131n eridi\u011fi yerlerde en iyi \u015fekilde g\u00f6zlemlenen e\u015fsiz ve b\u00fcy\u00fcleyici bir manzarad\u0131r.<\/p>\n\n

Buzullar\u0131n G\u00fczelli\u011fi ve \u00d6nemi<\/h2>\n\n

Buzullar sadece ilham verici do\u011fal harikalar de\u011fil, ayn\u0131 zamanda d\u00fcnya ekosisteminin hayati bile\u015fenleridir. Yaban hayat\u0131na habitat sa\u011flarlar, su ak\u0131\u015f\u0131n\u0131 d\u00fczenlerler ve gezegenin so\u011futma sistemine katk\u0131da bulunurlar.<\/p>\n\n

K\u00fcresel \u0131s\u0131nma nedeniyle buzullar\u0131n kayb\u0131, \u00e7evre ve insan uygarl\u0131\u011f\u0131 i\u00e7in ciddi bir tehdittir. Buzul erimesinin nedenlerini ve etkilerini anlamak ve y\u0131k\u0131c\u0131 sonu\u00e7lar\u0131n\u0131 azaltmak i\u00e7in harekete ge\u00e7mek \u00e7ok \u00f6nemlidir.<\/p>","protected":false},"excerpt":{"rendered":"
