Four of the 10 countries most affected by climate change are members of the Association of Southeast Asian Nations (Asean), United Nations secretary-general António Guterres said on Sunday, urging the Asean Summit in Bangkok to “confront the world’s climate emergency”.“This region is highly vulnerable, particularly to rising sea-levels, with catastrophic consequences for low-lying communities, as recently published research illustrated”, he said, pointing out that 70% of the global population most at risk of rising sea levels are within Asean and other countries that will be represented at summits later this week.
