Yak\u0131n zamanda yap\u0131lan ve alt\u0131 k\u00fcresel tar\u0131m ekonomisi modelini kullanan bir analize g\u00f6re, ozonun azalmas\u0131, iklim \u00f6nlemlerinin 2050 y\u0131l\u0131na kadar a\u00e7l\u0131k \u00fczerindeki olumsuz etkisini %15 oran\u0131nda azaltabilir.<\/p>\n
Yer seviyesindeki ozon, metan, azot oksitler ve u\u00e7ucu organik bile\u015fikler gibi kirleticilerin g\u00fcne\u015f \u0131\u015f\u0131\u011f\u0131 etkisiyle reaksiyona girmesi sonucu olu\u015fur.

Bunun aksine, ozonun azalmas\u0131, \u00f6zellikle Hindistan ve \u00c7in’de bu\u011fday verimini art\u0131rarak bu olumsuz etkilerin bir k\u0131sm\u0131n\u0131 dengelemektedir.<\/p>\n
