Perspective: California’s Coastal Challenges Amid Climate Change
Maintaining coastal sustainability will require a unified, whole-of-society response. The report calls on research institutions, urban planners, policy makers, and community organizations to come together to address threats like habitat loss, saltwater intrusion, and risks to infrastructure. The authors hope to foster collaboration on innovative policies for coastal development, conservation strategies, and risk management. To ensure California’s coastal zones remain viable, the report encourages community-level action and policy reforms that address these challenges head-on. This includes expanding research into how ecosystems respond to stressors, identifying sustainable land-use practices, and implementing protective measures that build climate resilience. Although the challenges may

* WHAT...Up to 1 to 2 feet of inundation above ground level expected in low-lying areas near shorelines and tidal waterways adjacent to the Pamlico Sound. * WHERE...Areas along Croatan, and Roanoke Sounds, Kitty Hawk Bay, and Pamlico Sound, and adjacent tidal creeks. * WHEN...Until 4 PM EST this afternoon. * IMPACTS...Up to 1 to 2 feet of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways resulting in a low threat of property damage. Some roads and low lying property including parking lots, parks, lawns, and homes adjacent to the waterfront will experience shallow
Intensified Coastal Hazards from Climate Change on U.S. Southeast Coast
While previous research has largely focused on flooding, the new study highlights additional threats such as groundwater hazards, land subsidence, and beach erosion. These hazards, often underappreciated in climate discussions, will be amplified by sea levels projected to rise by one meter over the next century. The study estimates that up to 70% of coastal residents and $1 trillion in property could face challenges from shallow and emerging groundwater. This risk is 15 times greater than the exposure to daily tidal flooding alone. Figure a, Coastal flooding (no storm), shallow groundwater exposure and erosion (unimpeded model case) for one meter
