Natural Resources Wales, the government-sponsored organization responsible for the sea defenses in Fairbourne, said the village is particularly vulnerable because it faces multiple flooding risks. Built in the 1850s on a low-lying saltmarsh, Fairbourne already lies beneath sea level at high spring tide. During storms, the tidal level is more than 1.5 meters (5 feet) above the level of the village.
Scientists say U.K. sea levels have risen about 10 centimeters (4 inches) in the past century. Depending on greenhouse gas emissions and actions that governments take, the predicted rise is 70 centimeters to 1 meter by 2100.
Fairbourne is also at the mouth of an estuary, with additional risks of flash floods from the river running behind it. Officials have spent millions of pounds in strengthening a sea wall and almost 2 miles of tidal defenses.Frustration, defiance in village to be abandoned to the sea – ABC News
