Temperature and precipitation increase and decrease because of natural causes. However, anthropogenic changes, such as an enhanced greenhouse effect, may result in alterations in the regional climate and in relative sea level. Serious changes in climate and sea level-with adverse effects particularly along low-lying coasts-would affect millions of people. Climate Change takes an in-depth, worldwide look at coastal habitation with respect to these natural and anthropogenic changes. No universally applicable coastal model can be used to describe climatic changes. This unique book provides individual discussions of beaches and barrier islands, cliffs, deltas, tidal flats and wetlands, reefs, and atolls. The impact of climatic change on coastal ecology and agriculture is investigated, and human responses to the effects of climatic change along the world's coasts are included.
