Sea level has risen much of the U.S. coastline over the last 50 years. Sea level of some locations in Texas increased more than 8 inches. By 2010, it is expected that sea level at the U.S. eastern coast could rise by 15 inches. One of the main reasons of the sea level rise is an increase of greenhouse gases in the atmosphere.
