Rising seas will swallow New Orleans. People need to start relocating now | Hacker News

Commenters reacted to a CNN warning that New Orleans faces worsening flood risk from both sea-level rise and sinking land.

Some noted that land subsidence is as important as rising oceans in driving the city’s relative sea-level threat.

Others argued that, instead of endlessly spending on flood defenses, New Orleans may eventually need to relocate vulnerable areas.

The debate highlights a broader climate policy question: whether to protect coastal communities or plan for managed retreat.
