A new study has examined the impact of global warming on people in Kiribati.
The University of the South Pacific social scientist, Doctor Uentabo Neemia-McKenzie, carried out the research.
Kiribati has only two seasons with one normally associated with rain and storm-carrying westerly winds.
Dr Neemia-McKenzie says now that surety has gone, people are more vulnerable to changes.
He says the study, funded by the World Bank and Japanese government, is a world first, in trying to measure the impact of global warming at a country's basic social level.
Dr Neemia-McKenzie went to Kiribati and asked what changes people there had seen in the last 30 years.
