According to a new technical report, the effects of climate change will continue to threaten the health and vitality of U.S. coastal communities’ social, economic and natural systems. The report, Coastal Impacts, Adaptation, and Vulnerabilities: a technical input to the 2013 National Climate Assessment, authored by leading scientists and experts, emphasizes the need for increased coordination and planning to ensure U.S. coastal communities are resilient against the effects of climate change.

The report’s authors noted that the population of the coastal watershed counties of the U.S. and territories, including the Great Lakes, makes up more than 50 percent of the nation’s population and contributed more than $8.3 trillion to the 2011 U.S. economy but depend on healthy coastal landforms, water resources, estuaries and other natural resources to sustain them. Climate changes, combined with human development activities, reduce the ability of coasts to provide numerous benefits, including food, clean water, jobs, recreation and protection of communities against storms.
