floating city?

a mile high tidal wave?

Even a city is capable of capsizing.

If mountains are going underwater, the world has ended, and no amount of floating is going to save you. Civilization ended and with it all the arable land and all the production facilities on which your city depends.

Imagine its built of warertight compartments that when broken apart by said initial wave they have inflatable buffers that keep them afloat but also buffered from each other. A skyscraper made of lifeboats fastened together basically but a lot more complex. If you know ots gonna happen you could build a house of cards designed to topple as softly as possible.

We don't need arable land if we can harness ocean power properly. Seaweed farms, seafood = basic food requirements met.

I agree we are probably fucked but what if it's a puny meteor that only takes out Europe and the dust cloud goes away in 6 months?

A) the actual complexities of a city made out of separable bulkheads all watertight and self sufficient is far beyond anything humanity has ever built, and things 1/1000th as complicated (like the soviet moon rocket) exploded when we tried.

B) Small scale seaweed farms are not going to feed 200,000 people and if they could the people would be hugely nutrition deficient and anyway the ecological collapse caused by such an event might ensure the seaweed doesn't even grow, with the nutrients in the water being eaten by massive algal blooms or worse

C) Major industries like metal smelting, plastics manufacturing, oil refining, chip fabrication, etc do not function on small scales and eat enormous amounts of power which you would not get from floating solar

D) We're talking about a 6 month dust cloud so the seaweed doesnt grow and the solar panels barely make any power for 6 months...everyone dies.

Just move to Kathmandu above the water line instead. It's cheaper and far less likely to fail
