The director of the Cook Islands climate change office says Pacific countries will be trying to apply as much pressure as possible in the latest round of United Nations climate talks.
The latest negotiations - known as COP25 in UN jargon - begin today in the Spanish capital, Madrid.
Over two weeks, leaders and representatives of every country will thrash out progress towards the Paris climate agreement of four years ago.
It comes amid of a wave of fury around the world towards inaction, led mainly by youth who took part in school strikes across the globe.
The director of the Cook Islands climate office, Wayne King, told RNZ Pacific's Jamie Tahana that more than ever, the pressure is on for world leaders to do something.
