“Retreat, hell!” Major General Oliver Prince Smith once said during the Korean War. “We’re not retreating, we’re just advancing in a different direction.”

Retreat is not a concept Americans take lightly, whether in wartime or during CNN’s climate town hall Wednesday night. There the topic was managed retreat or strategic retreat, a deliberate pulling back from coastal areas. It means giving up some buildings and infrastructure to the rising sea while moving others. It’s also a strategy that scientists frequently turn to when debating how waterfront cities and towns will adapt to climate change.

Andrew Yang: “We would 100 percent make funds available to communities around the country for adaptation and resilience.”

Amy Klobuchar: “I’ve been through this mitigation issue for flooding in my own state … sometimes we find a way to move their homes, to move them off flooding areas that keep consistently flooding, because otherwise they’re paying too much money.”
