What Are Barrier Islands and How Are They Affected by Climate Change?

Abstract

Barrier islands are complex ecosystems that exist off the coast of every continent except Antarctica. They protect the coastline from direct impacts of storms and sea-level rise. These islands are home to people and animals, some of which are endangered. Barrier islands naturally move and change shape, but climate change and human development can prevent this movement, disrupting natural processes. Conservation of barrier islands is important for providing habitats for plants and animals as well as for protecting the coast of the mainland.
