• Programmed coastal retreat replaces repeated reconstruction in selected exposed jurisdictions — 2072–2082, ChatGPT
• Routine managed retreat and elevation standards become dominant coastal policy in multiple major river deltas — 2072–2082, Grok
• The northern Nile Delta is written off as farmland and Egypt relocates its agricultural base — 2072–2082, Claude
