EPA releases report on sea level rise

The US Environmental Protection Agency, in collaboration with other agencies, has released a report that discusses the impacts of sea level rise on the coast, coastal communities, and the habitats and species that depend on them. The report, Coastal Sensitivity to Sea-Level Rise: A Focus on the Mid-Atlantic Region, examines multiple opportunities for governments and coastal communities to plan for and adapt to rising sea levels. 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 can already 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 ic...
