Sea-level rise can affect coastal communities and habitats in a variety of different ways, including submerging low-lying lands, eroding beaches, converting wetlands to open water, intensifying coastal flooding, and increasing the salinity of estuaries and freshwater aquifers. It is caused by a number of natural and human-induced factors and can vary by region. Some impacts of sea-level rise already may be observed along the U.S. coast.
The primary causes of global sea-level rise are the expansion of ocean water due to warming and the melting of glaciers and ice sheets. Locally, sea-level rise is also influenced by changes to the geology of coastal land, making coastal elevation mapping an important area of future study. The Mid-Atlantic region, the focus of this report, is one of the areas in the U.S. that will likely see the greatest impacts due to rising waters, coastal storms, and a high concentration of population along the coastline.
The report is one of 21 climate change synthesis and assessment products commissioned by the U.S. Climate Change Science Program (CCSP). CCSP was established in 2002 to provide the U.S. with science-based knowledge to manage the risks and opportunities of change in the climate and related environmental systems. The program is responsible for coordinating and integrating the research of 13 federal agencies on climate and global change.
