Editor’s note: We’re publishing a series from The Story Group that shows Americans on the front lines of climate change. The videos put faces to the warnings in the latest National Climate Assessment.

“We are a coastal country,” says Susanne C. Moser, a convening lead author for the National Climate Assessment’s Coasts chapter. The U.S. has 94,000 miles of coastline and more than $1 trillion in coastal infrastructure. Coastal lifelines, such as water and energy infrastructure, and nationally important assets, such as ports, tourism, and fishing sites, all are increasingly vulnerable to sea-level rise, storm surge, erosion, flooding, and related hazards.
