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
