August 15, 2018 — Climate change is negatively impacting our relationship with our state’s coast. Our famous beaches are taking a heavy hit from rising sea levels. Meanwhile, loss of property, loss of natural coastal habitats, and changes to our fisheries threaten our economic well being.
Sea levels are rising especially fast in the southeast, bringing potentially devastating losses to property values and real estate. Hurricane damage and chronic flooding due to rising seas a huge concerns. By 2045, more than 15,000 homes are at risk of being flooded on more than 26 days every year.
In addition to the property losses, so much sand is being eroded from beaches at Nag’s Head that the state spent $36 million to pump new sand from the sea floor onto beaches in 2014 and will spend $48 million in 2018. This brings total state spending on beach nourishment since 1990 to $640 million. The rising costs of beach nourishment impacts our state’s coastal tourism economy, which brought in an estimated $3 billion in 2013 according to N.C. Department of Commerce. With sea level predicted to rise at least 1 foot and by as many as 8 feet by 2100, there is much at risk.
Sea-level rise is not our only problem. Pamlico Sound had changed from an occasional feeding ground to a shark nursery as a direct result of climate change. Pamlico Sound already had many of the features of a good bull shark nursery: ocean access, proper salinity, and plenty of prey fish. The only missing piece was warmer water temperature. While adult bull sharks have been occasionally encountered in the sound for a long time, the sudden appearance and consistent presence of juveniles after 2011 signaled a change that has been correlated with rising water temperatures, particularly during late spring and early summer when bull sharks give birth.
