Climate change appears not to be as great a threat to life in Fiji as it is for the low-lying nations of Tuvalu and Kiribati. Studies are ongoing about of what part it plays for rural villages as they try to maintain their way of life. Programs by the Pacific Center for Environment and Sustainable Development (PACE) of the University of the South Pacific, Suva, are working with Fijian villages to assess their vulnerability to climate change and ability to adapt. Major issues throughout Fiji flow around water, including erosion, tidal flooding, mangrove protection, coral restoration, drought and protection of water sources. Here, Pastor Nikola Serewai describes features of the landscape on the NW coast of Viti Levu island in Ra Province from which his village of Barotu gets most of its water. We accompanied researchers from the PACE program.Greenhouse gasses are gasses are in the earth’s atmosphere that collect heat and light from the sun. With too many greenhouse gasses in the air, the earth’s atmosphere will trap too much heat and the earth will get too hot. As a result people, animals, and plants would die because the heat would be too strong.Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die.- freewallpaperdesktopbackgrounds.blogspot.com
Global warming is affecting many parts of the world. Global warming makes the sea rise, and when the sea rises, the water covers many low land islands. This is a big problem for many of the plants, animals, and people on islands. The water covers the plants and causes some of them to die. When they die, the animals lose a source of food, along with their habitat. Although animals have a better ability to adapt to what happens than plants do, they may die also. When the plants and animals die, people lose two sources of food, plant food and animal food. They may also lose their homes. As a result, they would also have to leave the area or die. This would be called a break in the food chain, or a chain reaction, one thing happening that leads to another and so on. The oceans are affected by global warming in other ways, as well. Many things that are happening to the ocean are linked to global warming. One thing that is happening is warm water, caused from global warming, is harming and killing algae in the ocean.This is the capital of the nation and is home to about half the total 12,500 population of Tuvalu. The island is only 500 meters wide at the widest, but most is much narrower, a thin strand about 60 meters wide and about 6 km long. The coral ridge along the ocean is no more than roughly 5 meters high, and along the lagoon the ridge is about a meter lower. Between sea level rise and severe storms, the seat of government is at risk of flooding.
The center of the island is a basin, with some low spots 2 to 3 meters above sea level. Even on calm King tide days, when waves do not crash over the high ocean and lagoon ridges, the pressure of the rising ocean forces salty ground water up into the low areas through the porous coral rock which makes up the island. People here have lived with flooding from storms and tides for generations, but more rapid sea level rise, increasing storm risk and changes to atoll shorelines put many more people at risk now.- freewallpaperdesktopbackgrounds.blogspot.com

The sun’s heat can get into the car through the windows but is then trapped. This makes what ever the place might be, a greenhouse, a car, a building, or the earth’s atmosphere, hotter. This diagram shows the heat coming into a car as visible light (light you can see) and infrared light (heat). Once the light is inside the car, it is trapped and the heat builds up, just like it does in the earth’s atmosphere.Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on. Without it, the earth would be freezing, or on the other hand it would be burning hot. It would be freezing at night because the sun would be down. We would not get the sun’s heat and light to make the night somewhat warm. During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter it, so people, plants, and animals would be exposed to all the light and heat.Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die.- freewallpaperdesktopbackgrounds.blogspot.com
