I'm looking for a TV pseudo documentary, from around 200x-201x. I watched it on cable, possibly Discovery Channel. The title may be similar to "water world" (the movie, I know)

  • A giant ice comet crashed with our Moon or passed Earth's Roche limit, forming a ring system around Earth.
  • These ice meteorites periodically come down, rise the sea level. And whenever a bigger piece falls down, a huge Tsunami formed, wreaking havoc around the world.
  • As the result, governments around the world start various plans to combat this situation.
  • Micronesia islands were gone first, created a refugee crisis.
  • The EU's plan is building a very high wall around their cities. But one failed catastrophically (a Spanish city I think), as the wall cannot be built high enough, created a huge number of death.
  • The US has 2 plans, one is moving higher inland (there could be a scene showing Hollywood Hills with a lot of refugees tent?). Another is build floating cities. Those cities are not one big structure, but a collection of smaller modules.
  • There is a talk about the floating cities being vulnerable to Tsunami, feature FLIP

I watched only the first episode, so I can only remember this much. I tried to google it with "floating city documentary", "ice comet strike", "flooded earth" to no avail.

  • Discover Channel: Earth Under Water? Shows lots of flooded cities. The end talks about floating cities

    Not submitting this as an answer as I can't provide any details but maybe this will help somebody identify it. There was a documentary series a few years ago about six different ways the world could end - one of them was flooding because of a ring of ice around the Earth which meant it rained for decades. I remember the wall being built around a Spanish city but there was a structural failure and the water got in. I think another episode in the series had self-replicating nanobots escaping from a military installation.

  • @Valorum - It's the same idea but that isn't the one. Neither the nanobots nor the worldwide flooding (as asked by the OP) are included.

1 Answer 1


I am pretty sure Evacuate Earth on NatGeo is the answer.

Evacuate Earth is a National Geographic Channel documentary that portrays the hypothetical scenario of humans evacuating the planet Earth before it is destroyed by a rogue neutron star. The documentary details the technical and social complications of building a generation ship to save humanity and other Earth organisms by relocating to a planet in another solar system.
