'Point of no return': New Orleans relocation must start now due to sea level

Original Article

Hacker News Discussion

📝 Discussion Summary (Click to expand)

1. New Orleans is doomed – no fix can hold back the water

“Even if you stopped climate change today, New Orleans’s days are still numbered… You can’t keep an island situated below sea level afloat. There’s no amount of money that can do that.” — dmm

2. Climate‑change talk is filtered out on HN

“Well discussing it was de facto banned on HN for many years (still wouldn't be surprised if this post disappears soon).” — crystal_revenge

3. Market realities & ethics trap residents in a sinking city

“We should have a one‑time buyout for flood zones: pay someone enough to buy a median home somewhere similar and turn the land into a nature preserve… but we won’t be willing to invest in our neighbors.” — adcah

“This is why the federal subsidies for flood insurance need to end.” — estearum
