At 463,000 square kilometers, Papua New Guinea (PNG) is the largest Pacific island state. Located in the South
West Pacific, it is bound by the Gulf of Guinea and the Coral Sea to the south, Indonesia to the west, the Solomon
Sea to the east, and the Bismarck Sea to the northeast. PNG comprises the eastern half of New Guinea island, four additional islands (Manus, New Ireland, New Britain, and Bougainville), and 600 smaller islets and atolls to the north and east. PNG is home to a diverse range of ecosystems, including mountain glaciers, humid tropical
The Papua New Guinea Government submits PNG’s first Biennial Update Report (BUR1) under the United Nations Framework Convention on Climate Change (UNFCCC). The report follows the BUR guidelines for developing countries according to paragraphs 39 to 42 of Decision 2/CP.17 and its Annex III.
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.
UNDP has been working during the last decade to support countries to transition to green, inclusive, climate-resilient development paths. More than US$790 million in grant financing from the Global Environment Facility-managed Least Developed Countries Fund and the Special Climate Change Fund, as well as the Kyoto Protocol’s Adaptation Fund and bilateral finance, have been mobilized to assist countries to achieve their adaptation
priorities. These resources build on and complement over US$2.5 billion in co-financing that has also been invested.

Climate change and migration
Papua New Guinea has large tracts of intact mangrove forest with a high species diversity extending over many thousands of shore kilometers and, in many regions, penetrating quite deeply inland.
Mangrove ecosystem is very useful and critical to PNG coastal communities. Its uses ranges from carbon sequestration, buffers coastlines against storm surges and sea level rise, breeding ground for fisheries, building, firewood, medicinal purposes to name a few.
Coral reefs in every region of the world are threatened by climate change, no matter how remote or well protected. Identifying and protecting climate refugia is a popular recommendation for coral reef management. Climate refugia are locations that maintain suitable environmental conditions for a resident species even when surrounding areas become inhospitable.
This chapter describes the diversity and distribution of mangrove, seagrass and intertidal flat habitats in the tropical Pacific (25°N–25°S and 130°E–130°W), outlining the role they play in supporting coastal fisheries in the region, and summarising the critical requirements for establishing and maintaining these habitats.
This report summarises the projected changes in ocean chemistry for the Pacific island region (from 130°E to 130°W and 25°N to 25°S) at regional and sub-regional scales, assessing the vulnerability of Pacific coastal and oceanic habitats and fisheries to ocean acidification using an established framework, and discussing the implications for the Pacific island communities dependent on fisheries and aquaculture for food security and livelihood
This CMEP report provides a summary of climate change impacts on coasts and seas in the Pacific island region, and how Pacific islands can respond.
This paper discuss impacts of climate change on corals according to standardized metrics. It also deals with non-climate drivers because of the synergistic effects they have with climate drivers affecting Pacific corals.
This report focuses on marine/coastal inundation and sea level and how they are affected by climate change.
The region of interest is the Pacific Islands, with a focus on Commonwealth countries (Fiji, Kiribati, Nauru, Papua New Guinea, Samoa, Solomon Islands, Tonga, Tuvalu and Vanuatu).
A major objective of this report was to develop a regional assessment of Pacific Island sensitivity to projected
climate change as a component of the Pacific-Australia Climate Change Science and Adaptation Planning
(PACCSAP) program. The PACCSAP Program is intended to help partner countries including Cook Islands, Fiji,
Kiribati, Marshall Islands, Federated States of Micronesia, Nauru, Niue, Palau, Papua New Guinea, Samoa,
Solomon Islands, Tonga, Tuvalu and Vanuatu and their communities better understand and respond to climate associated impacts.
