The prime minister of Tuvalu, Enele Sopoaga, says talk of relocating people to avoid the impact of sea level rise is self-defeating and should end.
Speaking ahead of the Pacific Islands Forum summit in the Marshall Islands, Mr Sopoaga says he wants action to stop climate change.
He says all the world is aware of the plight of the low-lying nations such as Tuvalu, but nothing is being done.
He says this talk includes discussion on relocation but that is utopian and inappropriate.
"It should never be an option because it is self defeating in itself. For Tuvalu I think we really need to mobilise public opinion in the Pacific as well as in the [rest of] world to really talk to their lawmakers to please have some sort of moral obligation and things like that to do the right thing."
