This Why Files article considers beach erosion. Topics covered are: the nature and extent of beach losses, the role of beaches in protecting coasts, some measures -good and bad- to prevent coastal erosion, predicted effects of global warming and sea-level changes on beaches and the impact of melting ice sheets on global ocean volume. Some glaciologists using new calculations, think that instead of possibly collapsing in 100 years, as was considered possible 10 years ago, that the West Antarctic Ice Sheet is more likely to collapse in perhaps 5,000 years at the soonest. Five scientists were interviewed for this article.
