  1. Problem • Climate change is projected to have severe impacts on North Carolina coastal resources • Extensive development in the coastal zone in recent decades has put more people and property at risk

  2. Climate change in coastal North Carolina • Sea-level rise • Complete loss of many beaches • Lost property values • Lost recreation and tourism values • Increased hurricane activity and intensity • Business interruption • Agricultural losses • Greater damage to forests • Commercial fishing losses

  3. Sea-level Rise and Coastal Inundation

  4. Land at risk due to sea level rise by 2100

  5. In this context, this study … • Considers the impacts of climate change on • coastal real estate • coastal recreation and tourism • business activity • We utilize a range of modest assumptions for sea-level rise and hurricane intensity increases, not best-case or worst-case scenarios.

  6. Coastal Recreation and Tourism

  7. Study Beaches

  8. Beach Width

  9. Impacts on Beach Recreation and Tourism • The lost recreation value to local beach goers • $93 million a year by 2030 • $223 million a year by 2080

  10. Fishing Sites: 22 piers, 28 beaches

  11. Impacts on Marine Recreational Fishing • The lost recreation value to local shore anglers • $15 million a year by 2030 • $17 million a year by 2080

  12. Coastal Real Estate

  13. Study Area

  14. GIS Real Estate Data

  15. Inundation for 2080-High

  16. Impacts on Coastal Property Value • The value of property at risk to sea-level rise in four counties over the next 75 years • $6.9 billion • Northern counties more vulnerable than the southern • Dare: 2% to 12% of the total property value

  17. Hurricane Activity and Intensity

  18. Hurricane Wind Speeds (Fran 1996)

  19. Impacts on Business and Industries • Business interruption losses in four NC counties due to increases in category 3 hurricane severity • $34 million per storm in 2030 • $157 million per storm in 2080

  20. Impacts on Agriculture • A category X hurricane now causes about Y in damage • 1 : $50 million • 2 : $200 million • 3 : $800 million

  21. Impacts on Forestry • Increased forest damage associated with an increase in storm severity from category 2 to category 3 • $900 million in additional damages

  22. Summary: Impacts of Global Warming on NC’s Coastal Economy • Over the next 75 years: • Lost recreational and tourism benefits total $3.9 billion • The value of property at risk to sea-level rise in four counties is $6.9 billion • Business interruption, agriculture and forestry losses due to increased storm severity are on the order of $1 billion in additional damage per category 3 storm event
