Coastal homes all the way from Maine to Florida are feeling the threat of sea level rise. Approximately 300,000 homes along the East and West Coast of the United States are at risk for reoccurring flooding due to sea level rise. According to National Geographic, the global mean sea level has risen four to eight inches over the past century. However, the rate at which sea level is rising has been twice as fast for the last 20 years when compared to the first 80 years of the last century.
Sea level rise is caused by three main factors, all of which are consequences of climate change. Thermal expansion, the melting of ice over Antarctica and Greenland, and the melting of polar ice caps and glaciers, all contribute to the measurable rise that researchers have observed over the past century. In 2012, The Intergovernmental Panel on Climate Change predicted that sea level could rise up to 38 inches by 2100.
Sea level rise has serious consequences for homeowners. By 2045, the slowly creeping disaster of chronic flooding could pose great threats to coastal housing markets. The Union of Concerned Scientists conducted a study on the effect that sea level will have on the East Coast and the Gulf area. Kirsten Dahl, an author of the study, stated that the loss of tax revenue from affected homes could cut the tax base of small towns by as much as 70 percent. Coastal homes are highly sought after real estate, but buying a beach house may not be the luxury it once was.
