About a million people live in coral atolls like those in the Maldives, Tuvalu, Kiribati, and the Marshall Islands. These islands are just a few feet in elevation, making them some of the places most at-risk from the rising seas that will result from climate change. Five uninhabited islands in the Solomon Islands have already vanished beneath the waves in the past century.
The Maldives, Kiribati, Tuvalu, and the Marshall Islands have the highest percentage of their land area at risk because they are all atolls; other countries also have low lying islands, but have more higher ground available to flee to.
