Sea-level rise

Article Abstract:

Coastal erosion is as inevitable as the rising of the tides. Natural erosion is often aggravated by other factors. Scientists have observed the rise in sea level by more than a foot over the past century. Such sea level fluctuations which lead to erosion, are believed to be partly magnified by a change in world climate. The atmosphere has steadily been growing warmer because of the presence of excess carbon dioxide released by the burning of fossil fuels. This warming or greenhouse effect melts ice caps and causes a rise in sea levels.

'Strategic retreat.' (solution to the threat of coastal development-caused erosion) (Threatened Coastlines: Outlook)

Article Abstract:

The threat of coastal erosion and the futility of trying to permanently control the phenomenon have led experts to suggest a 'strategic retreat' from development in high-risk locations. This recommendation is considered less costly than present efforts to replenish beaches and fortify the coastline. Preservation efforts are likely to fail because of the vagaries of ocean storms. A right step in the 'strategic retreat' movement is the establishment of setback rules. Regulatory agencies will have to assertively develop a unifies policy.

The issues

Article Abstract:

The development of coastlines as homesites has resulted in erosion and ultimate danger to coastal residents. Three issues cause questions about the reliability of present beach protection methods; whether government subsidy unwittingly encourages people to build in high-risk areas; and, whether the bureaucratic structure and consequent lack of coordination of government, impedes the effective development of the coastal areas. The problem centers on the need to temper the demand for coastal development with environmental concerns.
