Pacific leaders say the impact of climate change has reached a crisis stage in their countries and urgent action is needed.
Leaders and representatives from Kiribati, Tuvalu, Nauru, Micronesia and Samoa addressed international media in Cancun, Mexico, where climate change is being discussed at a United Nations conference.
The leaders called for direct and easy access to funding for adaptation and mitigation, and for agreements to extend the Kyoto Protocol, Radio New Zealand International reports.
The Prime Minister of Samoa, Tuilaepa Sailele Malielegaoi, says they just have to push and push to get the big countries to agree and hope that good sense will eventually prevail.
The meeting in Cancun is due to end on Saturday. No agreements have yet been reached cutting emissions, funding for developing countries to deal with climate change, or how to reduce deforestation.
