Tiny Tuvalu could quash climate deal
Prime Minister Apisai Ielemia brags that his tiny 9-island state of Tuvalu is the world’s smallest independent country. Its 10,000 inhabitants live an average of 2 meters above sea level, which makes their homeland highly vulnerable to disappearing with even modest sea-level rise. With the nation’s survival so dependent on climate protection, he vowed today that Tuvalu will not sign onto any climate-change accord that does not require “legally-binding” language and programs aimed at ensuring global temperatures peak at “well below” 1.5 oC. That could effectively torpedo hopes for a climate accord tomorrow when the United Nations climate change meeting is slated to wrap up.
