Elde edilen veriler, bilim insanlar\u0131na Akdeniz kurakl\u0131\u011f\u0131 olu\u015fumunda do\u011fal varyasyonun etkileri ile insan kaynakl\u0131 k\u00fcresel \u0131s\u0131nma aras\u0131ndaki farkl\u0131l\u0131klar\u0131 g\u00f6sterdi.

Bu sayede, Kuzey Afrika, Yunanistan, L\u00fcbnan, \u00dcrd\u00fcn, Suriye, T\u00fcrkiye, \u0130spanya, Fransa’n\u0131n g\u00fcneyi ve \u0130talya’y\u0131 kapsayan analizler ile ge\u00e7ti\u011fimiz 1000 y\u0131l\u0131n co\u011frafi kurakl\u0131k izlerine ula\u015f\u0131ld\u0131.<\/p>\n

Ayn\u0131 zamanda 1100 ve 2012 y\u0131llar\u0131 aras\u0131ndaki tarihsel dok\u00fcmanlar incelendi ve kurakl\u0131k d\u00f6nemleri tespit edildi. Ben Cook’a g\u00f6re, T\u00fcrkiye’nin de yer ald\u0131\u011f\u0131 Do\u011fu Akdeniz’de 1998 – 2012 y\u0131llar\u0131 aras\u0131nda g\u00f6r\u00fclen kurakl\u0131k, son 500 y\u0131l\u0131n en ‘kuru’ d\u00f6neminden y\u00fczde 50 oran\u0131nda daha \u015fiddetli ge\u00e7ti. Son 900 y\u0131la g\u00f6re ise en kurak d\u00f6nemden y\u00fczde 10 – 20 aras\u0131 daha k\u00f6t\u00fcyd\u00fc. Bu kurakl\u0131\u011f\u0131n etkileri ise halen devam ediyor.<\/p>\n

\u0130klim bilimci Ben Cook, ara\u015ft\u0131rmayla ilgili yapt\u0131\u011f\u0131 a\u00e7\u0131klamada, “\u0130nsan kaynakl\u0131 iklim de\u011fi\u015fikli\u011finin \u00f6nemi ve b\u00fcy\u00fckl\u00fc\u011f\u00fc, do\u011fal iklim de\u011fi\u015fkenli\u011finin boyutlar\u0131n\u0131 anlamam\u0131z gerekti\u011fini g\u00f6sterdi.

Ara\u015ft\u0131rmaya kat\u0131lan ekipteki Yochanan Kushnir de, “Akdeniz, gelecekte insan kaynakl\u0131 iklim de\u011fi\u015fikli\u011finden en \u00e7ok etkilenecek b\u00f6lgelerden biri. Bu ara\u015ft\u0131rma g\u00f6sterdi ki, son \u015fiddetli kurakl\u0131k, ge\u00e7mi\u015f as\u0131rlardaki do\u011fal kurakl\u0131klardan farkl\u0131l\u0131k g\u00f6steriyor.
