Abstract

The Paris Agreeement aims to keep global warming well below 2°C above preindustrial levels with a preferred ambitious 1,5°C target. Developing countries, especially small island nations, pressed for the 1,5°C target to be adopted but who will suffer the largest changes in climate if we miss this target? Here we show that exceeding the 1,5°C global warming target would lead to the poorest experiencing the greatest local climate changes. Under these circumstances greater support for climate adaptation to prevent powerty growth would be required.

1,5 İLE 2°C ARASINDAKİ KÜRESEL ISINMANIN, İKLİM DEĞİŞİKLİĞİNDE YARATTIĞI EŞİTSİZLİK

Abstract

Paris Anlaşması, sanayi devrimi öncesi seviyeden bugüne kadar artan küresel ısınmayı 2°C’nin altında tutmayı amaçlamaktadır. Hedefte tercih edilen, ısınma artışının 1,5°C seviyelerinde tutulmasıdır. Gelişmekte olan ülkeler, özellikle küçük ada ülkeleri, 1,5°C’lik hedef için baskı yapmaktadır. Bu hedefe ulaşılmadığında, iklimdeki büyük değişikliklerden en fazla kim etkilenecektir? Burada, 1,5°C’lik küresel ısınma hedefinin aşılmasının büyük yerel iklim değişikliklerinin yaşandığı yerlerde yoksulluğa yol açacağı gösterilmektedir. Bu koşullar altında yoksulluk artışını önlemek için en fazla desteğin iklim adaptasyonuna verilmesi gerekmektedir.
