A 10-foot sea level rise would inundate low-lying communities, disrupt transportation networks, and threaten critical infrastructure such as ports, roads, and water systems. Coastal wetlands and barrier islands would lose ground, reducing natural protections against storms. Saltwater intrusion could compromise freshwater supplies and agricultural lands, particularly in areas like the Florida Keys. Communities would face difficult decisions about protecting or relocating neighborhoods, infrastructure, and ecosystems. The economic and social costs of these changes could be significant, with impacts on businesses, fisheries, and daily life.
