Climate change is already here. On Long Island, communities must prepare, and people find ways to adapt to rising tides and extreme weather that threatens America's first suburbs. Higher Ground tells the stories of these communities exploring solutions that may or may not give them the best chance at survival and help save the places millions of people call home. Or they may discover that the only way forward for suburban America is retreating from the sea. Hosted and reported by J.D. Allen.
