What two climate zones are found in New Guinea?

Papua New Guineas climate can be described as tropical climate, with the coastal plains averaging a Temperature of 28°C, the inland and mountain areas averaging 26°C, and the higher mountain regions, 23°C.

How do the southeast and northwest monsoonal winds influence PNG climates?

The rainy season can expect heavier rainfalls courtesy of the northwest monsoon, while the dry season sees trade winds from the south east that bring dry, cooler weather.

What are the two seasons in PNG?

Papua New Guinea has a hot, humid tropical climate which is experienced all year round. The country experiences two distinctive seasons: wet (December – March) and dry (June – September).

What is the main effect on the climate of PNG?

The main climate drivers for PNG are the El Niño – Southern Oscillation (ENSO), the West Pacific Monsoon and to a lesser extent the position of the South Pacific Convergence Zone (SPCZ). The influence of ENSO on rainfall is stronger in the Southern and Mainland than the Northern regions.

What climate zone is Papua New Guinea?

Papua New Guinea Climatic Classifications

Summary: Most regions (22) in Papua New Guinea lie in the Tropical rainforest climate zone (Köppen: Af). The mean average of annual temperatures range from a high of 27.92°C (82.26°F) in Manus to a low of 15.29°C (59.52°F) in Western.

What landscape is Papua New Guinea?

Papua New Guinea is largely mountainous, and much of it is covered with tropical rainforest. The New Guinea Highlands run the length of New Guinea, and the highest areas receive snowfall—a rarity in the tropics. Within Papua New Guinea Mount Wilhelm is the highest peak, at 4,509 m (14,793 ft).

What are the effects of global warming in PNG?

Increasing temperatures, coupled with diminishing fresh water sources and persistent droughts, hamper agricultural processes at the cornerstone of the Papua New Guinean economy and the population’s livelihood. By 2030, the country’s temperature will increase by up to 1.1° Celsius (33.98° Fahrenheit) per year.

What climate zone is Port Moresby?

tropical savanna climate

Climate. Moresby has a tropical savanna climate (Köppen: Aw) with relatively constant temperatures throughout the year. Port Moresby’s average yearly rainfall is just over 1,000 millimetres or 39.37 inches, making it the driest place in New Guinea.

Why does PNG experience hot and wet climate?

The climate is influenced by the monsoon circulation: the northwest monsoon prevails from December to April, and the southeast monsoon from May to October. Usually, each monsoon brings rainfall on the exposed slope, but in many areas, it rains during both the monsoons, so it rains all year round.

How can climate change affect human health in Papua New Guinea?

Loss of wetlands, changes to the fisheries, forestry and agriculture sectors, alteration to water resources and land use practices and impacts on health, particularly vector borne diseases such as Malaria other related water and air borne disease are also expected.

Why does PNG have high rainfall?

Precipitation is dependent on two wind systems—the southeast trade winds and the northwesterly turbulence zone (the monsoon)—and on the three site characteristics of latitude, elevation, and exposure.

What is this climate change?

Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil and gas.

What happens if we do nothing climate change?

What happens if we do nothing to stop climate change? If we do not take further action to stop climate impacts we’re already experiencing, the planet is likely to see global temperatures rise by 2-4 °C (3-7 °F) by the end of the century.

What happened to the Carteret Islands?

Flooding. It was widely reported in November 2005 that the islands have progressively become uninhabitable, with an estimate of their total submersion by 2015. The islanders have fought a more than twenty years’ battle, building a seawall and planting mangroves.

What is global warming for kids?

Global warming is the term used to describe the rising of the average temperature on Earth. It has to do with the overall climate of the Earth rather than the weather on any given day. History of Global Temperatures. The Earth has gone through changes in temperature before.

Why is global warming happening?

Temperatures are rising world-wide due to greenhouse gases trapping more heat in the atmosphere. Droughts are becoming longer and more extreme around the world. Tropical storms becoming more severe due to warmer ocean water temperatures.

How long is the earth going to last?

The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters. If humans last that long, Earth would be generally uncomfortable for them, but livable in some areas just below the polar regions, Wolf suggests.

What is the greenhouse effect?

Greenhouse gases

The greenhouse effect: some of the infrared radiation from the Sun passes through the atmosphere, but most is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds. The effect of this is to warm the Earth’s surface and the lower atmosphere.

What is global warming for 6th graders?

global warming—refers to the general increase in the earth’s average temperature, which causes changes in climate patterns across the globe. The earth’s average temperature has been increasing over the last century.

What is global warming 4th?

“Global warming is a gradual increase in the earth’s temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.

How does greenhouse cause global warming?
