USGS geologist Patrick Barnard gave a live interview to Philadelphia's NBC10 meteorologist Tammie Souza on January 23 during a national weather conference in Lake Tahoe, California.

Barnard explained that U.S. East Coast communities face increasing flooding threats from a combination of accelerating sea-level rise, subsidence of coastal land, and severe storms. Barnard leads development of the Coastal Storm Modeling System (CoSMoS), which combines projected sea-level rise with a range of storm intensities to predict coastal flooding along West Coast shores. Several California communities are already using CoSMoS projections to plan for future flooding threats. View the interview (3 minutes).
