The South Pacific island nation of Kiribati (pronounced Kir-uh-bahs) is comprised of 32 atolls and a raised coral island. It is the only nation in all four hemispheres of the Earth. But the future of the 100,000 residents is uncertain because of fears that global climate change will raise the ocean levels, making Kiribati, which is only 6 feet above sea level, uninhabitable by the 2050s.
