K\u00fcresel \u0130klim De\u011fi\u015fikli\u011fi Nedir?<\/span><\/strong><\/p>\n\n\n\n
\u0130klim de\u011fi\u015fikli\u011fi, gezegenin hava durumu modellerinde ve ortalama s\u0131cakl\u0131klarda b\u00fcy\u00fck \u00f6l\u00e7ekli, uzun vadeli bir de\u011fi\u015fimi ifade eder.<\/p>\n\n\n\n
Bilim insanlar\u0131, y\u0131llarca s\u00fcren g\u00f6zlemler, teori geli\u015ftirme ve model olu\u015fturma yoluyla D\u00fcnya’n\u0131n iklim sistemi hakk\u0131nda bir anlay\u0131\u015f geli\u015ftirdiler. Bug\u00fcn, iklim de\u011fi\u015fikli\u011finin meydana geldi\u011fini ve bunun insan faaliyetlerinden kaynaklanan sera gaz\u0131 emisyonlar\u0131n\u0131n bir sonucu oldu\u011funa art\u0131k eminiz.<\/p>\n\n\n\n
Bu sonu\u00e7, d\u00fcnyadaki ortalama hava modellerindeki uzun vadeli de\u011fi\u015fimi anlam\u0131na gelir. \u0130nsanl\u0131\u011f\u0131n 1800’lerin ortalar\u0131ndan beri havaya karbondioksit ve di\u011fer sera gazlar\u0131n\u0131n sal\u0131m\u0131na katk\u0131da bulunmas\u0131yla, k\u00fcresel s\u0131cakl\u0131klar y\u00fckseldi ve iklimde uzun vadeli de\u011fi\u015fikliklere neden oldu. <\/p>\n\n\n\n
K\u00fcresel iklim krizinin etkileri bug\u00fcnden hissediliyor ve gelecekte de artarak devam edecek. K\u00fcresel sera gaz\u0131 emisyonlar\u0131n\u0131 azaltmaya y\u00f6nelik eylemler, iklim sisteminde de\u011fi\u015fiklikleri s\u0131n\u0131rlamaya yard\u0131mc\u0131 olmak i\u00e7in yeterli.<\/p>\n\n\n\n

Sanayi Devrimi, insanlar\u0131n yak\u0131t olarak k\u00f6m\u00fcr, petrol ve gaz gibi fosil yak\u0131tlar\u0131 yakmaya ba\u015flad\u0131\u011f\u0131 1800’lerin ortalar\u0131na denk gelmektedir. Bu d\u00f6nemden 11.000 y\u0131l \u00f6nce d\u00fcnya \u00e7ap\u0131nda ortalama s\u0131cakl\u0131k yakla\u015f\u0131k 14\u00b0C’de sabitti.<\/p>\n\n\n\n
Fosil yak\u0131tlar\u0131 yakmak enerji \u00fcretir, ancak ayn\u0131 zamanda havaya karbondioksit, metan ve nitr\u00f6z monoksit gibi sera gazlar\u0131 salar. Zamanla bu gazlar\u0131n b\u00fcy\u00fck miktarlar\u0131 atmosferde birikmi\u015ftir.<\/p>\n\n\n\n
Atmosfere girdikten sonra, karbondioksit gibi sera gazlar\u0131 gezegenin etraf\u0131nda \u00f6rt\u00fc benzeri bir yap\u0131 olu\u015fturur. Bu \u00f6rt\u00fc, g\u00fcne\u015ften gelen \u0131s\u0131y\u0131 hapseder ve d\u00fcnyan\u0131n \u0131s\u0131nmas\u0131na neden olur. Buna \u201csera etkisi\u201d diyoruz.<\/p>\n\n\n\n
Sera etkisi 1980’lere kadar g\u00f6zlemlenip fark edildi. 1988’de h\u00fck\u00fcmetlere iklim kriziyle m\u00fccadele konusunda bilgi sa\u011flamak i\u00e7in H\u00fck\u00fcmetleraras\u0131 \u0130klim De\u011fi\u015fikli\u011fi Paneli (IPCC) kuruldu.<\/p>\n\n\n\n
