This report is a result of a field work - it took an environmental and physical approach of the situation of Kiribati with the objectives to better understand the formation and recent evolution of sedimentary coasts, in particular tropical islands (Indian Ocean and Caribbean Sea archipelagos) and to analyze interrelations between physical processes and human development to determine the nature and extent of anthropogenic impacts, particularly in coral reef environments as well as to evaluate the exposure of islands to coastal hazards related to climate and climate change.
This chapter provides a brief description of Papua New Guinea, its past and present climate as well as projections for the future. The climate observation network and the availability of atmospheric and oceanic data records are outlined. The annual mean climate, seasonal cycles and the influences of large-scale climate features such as the West Pacific Monsoon and patterns of climate variability (e.g. the El Niño‑Southern Oscillation) are analysed and discussed.
