Pacific island nations have shaped the international response to climate change. At the United Nations summit in Glasgow, they’ll draw a line in the sand. Chair of the Pacific Islands Forum, Fiji prime minister Frank Bainimarama, has said Pacific island countries ‘refuse to be the canary in the world’s coal mine.’ The Pacific Islands are at the frontline of climate change. But as rising seas threaten their very existence, these tiny nation states will not be submerged without a fight. For decades this group has been the world’s moral conscience on climate change. Pacific leaders are not afraid to call out the climate policy failures of far bigger nations, including regional neighbour Australia. And they have a strong history of punching above their weight at United Nations climate talks – including at Paris, where they were credited with helping secure the first truly global climate agreement.
