The article looks at migrants who have left their home countries due to the effects of climate change and global warming, termed climate refugees. It profiles Ioane Teitiota, a man from the Republic of Kiribati, who moved with his wife to New Zealand after suffering repeated flooding in Kiribati, and recounts his effort to stay in New Zealand despite the expiration of his visa on the grounds of climate refugee status. Topics include Teitiota's attorney, Michael Kidd; estimates of the number of people displaced by flooding and other natural disasters linked to climate change; and proposals for a new international treaty on the subject. Comments are also present from Kiribati President Anote Tong.
