Figure 7:  Over the past 100 years, sea level has risen about 0.3 m (~12 in) in the U.S. Mid-Atlantic region. About half of this change has been due to worldwide sea-level rise and about half has been due to other factors. Climate change is projected to cause the rate of global sea-level rise to increase, implying an overall rise of ~0.65 m (~26 in) by 2100 in the Mid-Atlantic region. The dots on this map show populated places, primarily in low-lying coastal areas (elevations of 1 m or less), that have homes and/or municipal infrastructure that may be increasingly exposed to ocean influences, particularly during storms and high tides (see Appendix D for further information).
