Climate change in Papua New Guinea

Department of Environment and Conservation

The Department of Environment and Conservation (DEC) was established in 1985. Its mission (approved by the National Executive Council on 22 August 1989) is to ensure natural and physical resources are managed to sustain environmental quality and human well-being.

The key legislations administered by the Department are:

Environmental Planning Act 1978

Environmental Contaminants Act 1978

Conservation Areas Act 1978

National Parks Act 1982

International Trade (Fauna & Flora) Act 1979

Fauna (Protection and Control) Act 1966

Crocodile Trade (Protection) Act 1974

Water Resources Act 1982

It also has an important role under the Forests Act 1992.


Climate Change and Development Authority (CCDA) is a new government entity that is now undergoing transition from the former Office of Climate Change and Development (OCCD). CCDA coordinates the Climate Change efforts of the Government of Papua New Guinea, a continuation of basically where the former OCCD left off. It is the coordinating entity for all climate change related policies and actions in the country. Additionally, it is the designated National Authority under the United Nations Framework Convention on Climate Change (UNFCCC). The office is currently undergoing a transitional phase which requires a major re-structure, in a coordinated and structured manner,complying with its own Climate Change Management Act (CCMA) 2015. The CCMA 2015 clearly defines this in Sections 8-11 of the Act on the organisation’s establishment, purpose, functions and powers.

CCDA is basically tasked with ensuring that Papua New Guinea follows a path of climate-compatible growth; that the country’s economy develops while simultaneously mitigating greenhouse gas emissions and reducing vulnerability to climate change related risks.


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. Observed trends and analysis of air temperature, rainfall,
extreme events (including tropical cyclones), sea-surface temperature, ocean acidification, mean and
extreme sea levels are presented. These projections are presented along with confidence levels based on
expert judgement by Pacific Climate Change Science Program (PCCSP) scientists. The chapter concludes
with a summary table of projections (Table 11.4). Important background information, including an explanation
of methods and models, is provided in Chapter 1. For definitions of other terms refer to the Glossary. Projections for air and sea-surface temperature, rainfall, sea level, ocean acidification and extreme events for the 21st century are provided.
