This article describes the geography of the Republic of Kiribati. Kiribati consists of 32 atolls and one island scattered over all four hemispheres in an expanse of ocean equivalent in size to the continental United States. The islands lie roughly halfway between Hawaii and Australia in the Micronesian region of the South Pacific. The three main island groupings are the Gilbert Islands, Phoenix Islands, and Line Islands. On 1 January 1995 Kiribati moved the International Date Line to include its easternmost islands and make it the same day throughout the country.
Kiribati includes Kiritimati (Christmas Atoll; in the Line Islands), the largest coral atoll (in terms of land area, not dimensions) in the world, and Banaba (Ocean Island), one of the three great phosphate rock islands in the Pacific.
Oceania, group of islands in the Pacific Ocean, straddling the equator, about one-half of the way from Hawaii to Australia; note - on 1 January 1995, Kiribati unilaterally moved the International Date Line from the middle of the country to include its easternmost islands and make it the same day throughout the country.
The Phoenix Islands Protected Area constitutes 11.34% of Kiribati’s Exclusive Economic Zone (EEZ) and with a size of 408,250 km2 (157,630 sq mi) it is the second largest marine protected area (MPA) in the Pacific Ocean.
The total land area mass total 811 km2 (313 sq mi). It includes three island groups - Gilbert Islands, Line Islands, Phoenix Islands. Most of the land on these islands is less than two metres above sea level. Including the amount of water, the total water and land area is 2485 square miles. A 1989 United Nations report identified Kiribati as one of the countries that could completely disappear in the 21st century if steps are not taken to address global climate change.
