^^ The leaders behind the Earth exodus would have been very short-sighted to not expect some survival after the disaster. Earth has had 5 mass extinctions in its history. But once life established a foothold on Earth some 3.5 billions years ago, it's never truly gone extinct. I'm not ready to guess on what life the leaders expected to survive the disaster. But for them to assume no life would survive seems like the stupidest choice to make.

Logically it should have been something way worse than a simple Ice Age.
At the very least they must have been convinced that the glaciation was irreversible. After all Ledo expected Earth to be still covered in ice.

If he's being lied to then there are even more reasons to think there isn't a simple Ice Age involved.
At any rate the fact that the planet froze was confirmed by the Gargantians themselves and the fact that it is water planet now isn't something that should have logically happened at the end of an Ice Age.

That's one of those things that we are just going to have to suspend disbelief on. If you melt the arctic and antarctic ice sheets completely, you'd get an about 68 meters higher water level - obviously not nearly enough to cover all land masses. It wouldn't even be enough to reach the valleys of most mountain regions. Even if all groundwater would spontaneously rise to the surface for unexplained gravity-defying reasons, that would add another 20 meters or so. And any comets carrying enough water (let's forget that it's mostly deuterium and not protium for the moment - the "water comes from comets" theory is mostly discredited these days) to cover the surface would probably completely devastate the earth.

If there's no dry land, there's no dry land, let it be handwaved rather than nitpicked.
It's potentially more interesting if there is dry land and the fleet has to learn to break its reliance/blind trust on the Sea Galaxy in order to get there/make use of it. Could be a job for Ledo and Chamber... |

The conclusion that our planet doesn't have enough water to submerge all the land is based on the assumption that every landmass will remain at the current altitude.
A water planet is still possible if for some reasons all the landmasses sink below the water level. We don't actually know how many years in the future we are or what kind of catastrophe happened, so this isn't completely impossible. Albeit it is very unlikely and I doubt this anime will actually provide such justification. What I was actually trying to say is that when an ice age ends the temperature should simply return to normal levels. Here however it seems that it became even higher, and that means that another event must have occurred to cause all that, an event that most likely the old Earthlings didn't predict and couldn't predict when they left.

The landmasses above/below water level are located on tectonic plates. While these plates essentially float on magma, it's not like they can really sink - probably not even if they get broken apart violently by some cataclysmic event, as the magma will just cool off and form new plates. But in the end, I doubt we'll get a scientific explanation - this anime is about human relationships after all
And since it was mentioned, I actually like Waterworld, improbable as it is. Water planets are cool |

As you said they are all floating on magma. While we have no knowledge of entire continents sinking or emerging, there are several cases of relatively minor landmasses emerging and sinking above and below the sea level. EDIT: check also Zealandia

Of course landmasses' can sink. What strikes me has highly unlikely, barring something cataclysmic which I've not ruled out, is "all" off them sinking. That would be akin to the entire planet shrinking big time. I'd think that phenomenon would heralded a lot of other issues in and of itself. Still, I'm not saying the writers can't cook up some half decent theory for what's happening. One theory I'd toss out is something like the planet being hit by a asteroid and having the planet tilt off axis comes to mind, since that could also explain some issues with the temperature (well if it's a issue but really, the ice caps should have reformed after that last ice age, land or no land above water) in general.
As for Waterworld, I saw it at a theater first-run. The theatrical version is not the extended cut many watched on TV growing up, which IMO is quite a bit better, but a shorter, harder to follow film. Still, my memories of the film are mixed. I didn't think it was a good film, though it did have a great look and it might have worked with better editing. Also, it was one of the last, if not the last, film I went to see in a theater with my mother (she was a fan of Kevin Costner) before she passed away. The best memory of the film I have is her turning to me during the scene where they were rowing the supertanker and asking me, in all seriousness, if the film was a comedy and then the two of us getting into a case of the giggles after I re-assured her that no, it was suppose to be a serious SF film (the scene had me thinking Monty Python's "Meaning of Life" so I knew exactly where she was coming from! ) |
