After Hurricane Irma destroyed 90% of homes on the Caribbean island of Barbuda in 2017, the government ¡ª faced with a second storm bearing down ¡ª evacuated all 1,600 residents to the nation¡¯s larger island, Antigua.

¡°What if Hurricane Irma had shifted some miles south and hit both islands?¡± pondered Prime Minister Gaston Browne in a speech to the U.N. Security Council on Tuesday, during a discussion on rising security risks linked to climate change.

As a warming world brings growing threats to lives and stability in vulnerable island states, ¡°what international plan and system would my country have recourse to, in the aftermath of such an attack to our peace and security?¡± he asked.
