What if you drained the oceans?

[Umbran]

Is not half the premise of Dune that Arrakis was once covered in water (and will be again) ?

If you believe prophecies and all, sure.
But right now (so to speak) there is no water on the surface at all.

Just pesky walking water bags.

So in these scenarios ... to where do the oceans drain?

Ah, then the answer is incomplete! What happens on Mars with all of that water? Does it freeze solid in an immense incrementally collapsing mountain of ice? Does it heat the surface sufficiently to remain liquid, eventually covering the entire surface — except, perhaps, one very tall extinct volcano? Would outgassing of dissolved oxygen and other gasses give Mars a thin temporary atmosphere? Could any creatures, from the smallest diatoms to the biggest whales, survive? How long until the great Mars-wide ocean freezes?

I think the consensus atm is even if you terraform mars it's magnerosphere isn't strong enough to retain its atmosphere long term. And gravity wouldn't be conductive to long term colonization.

Venus is a better candidate assuming you have the technology to terraform (I treat it as magic atm).

No, the answer isn't incomplete as the question was "where do the oceans go?" nor was it the topic of the video. But anyway here's the text version that answer the question of "what happens next?" Drain the Oceans: Part II
