The Marshall Islands has issued a plea for help and a call to action at the US Leaders Summit on Climate Change.

Addressing the virtual meeting on Friday, President David Kabua laid out the existential threat facing his country and the Pacific.

AKabua is the lone Pacific leader invited by US President Joe Biden to the two-day talks.

Kabua shared the stage with the world's biggest economies and pressured those he said held the Pacific's future in their hands.
