The issue will likely dominate this week’s Pacific Islands Forum leaders’ summit in Port Moresby, ahead of the United Nations climate change conference in Paris later in the year.
Pacific leaders want the world to work on restricting the global warming temperature rise to 1.5C, fearing a 2C target will risk the survival of many tiny islands.
Natural disaster recovery will be fresh on their minds. The summit starts on Monday, six months after Cyclone Pam, which flattened much of Vanuatu and caused heavy flooding on Tuvalu, Kiribati and the Marshall Islands.
