Nepal’s recent catastrophic floods, which have killed more than 1,340 people and left nearly 5,000 missing,?according to the country’s disaster management agency,?could change the way the world confronts the mounting climate-driven losses of developing nations.

Later this month, Nepal’s Prime Minister Balendra Shah will make his first foreign trip six months after taking office, traveling to New York to lead a small delegation to the 81st session of the United Nations General Assembly. He will seek climate justice for Nepal and international support following the disaster along the Nepal-China border. Shah is scheduled to speak during the U.N. General Assembly’s general debate on Sept. 24.

The floods struck Aug. 26, when a mass of water, mud and ice broke loose near the Nepal?China border and swept through villages, devastating homes, infrastructure and the people who lived and were visiting there. Nepal observed a national day of mourning 13 days after the disaster.
