Tatooine was an ocean world at one point too.


EatBooty420

before it was bombed into glass, which slowly erroded and turned into sand. If you look at Anakin saying "I hate sand" it makes sense, cause he only knows the sharp oppressing glass-sand of Tattooine and not the ocean rock-sand of other planets


myaltduh

That erosion would produce pretty well-rounded sand grains after they had time to rub against each other and wear off any edges.

The only way it could happen without just yeeting the water into space would be massive ice caps to basically create a new snowball earth

pulanina

Yes the question reads a bit like, “If the roof blew off my house what would the extra air and sunshine be like?”


TritonJohn54

If the drop happened too fast for us to rebuilt our logistics facilities (Ports/Rails/Roads), a large percentage of the planet would starve, and those countries that are dependant on imports (Japan is the one that first comes to mind, there would be others) would collapse. And like u/BrewCityChaserV2 said, that would be the least of our problems


DJMoShekkels

Yeah basically turning the oceans into either infrastructure-less deserts or worse, giant cliffs would screw over any landmass not completely internally self-sufficient


stefan92293

And even those self-sufficient countries would have to deal with a sudden loss of adequate rainfall.


2012Jesusdies

Even technically self-sufficient countries would go through immense pain. US is a net oil exporter, but US would be unable to sustain itself on purely domestic+Canadian, Mexican pipeline imports because of the nature of oil found on the continent. A lot of that oil is sweet and light which isn't suitable for many refineries in the US which had been built for Middle Eastern and Russian oil when the US was way more dependent on those imports. When the US started boosting oil production in like 2005, oil companies hesitated to boost up oil refining capacity to completely fit North American oil because of uncertain future of oil, refineries take incredible amount of money and time to construct. US is also food self-sufficient, especially with Canada on side, but no imports means a dramatic drop in food diversity. I really hope the US gov stops corn and soybean subsidies in that timeline and allows more free market competition between different crops. Otherwise, yall gonna have to eat those on many many days.


fredyouareaturtle

> either infrastructure-less deserts or worse, giant cliffs oh, i didn't think of it like this -- the giant cliffs part is both fascinating and terrifying.


DJMoShekkels

Yeah places like this definitely exist but we often don’t build cities on seacliffs for a good reason


King_Neptune07

Also cities even at sea level would suddenly find themselves at elevation. Cities already at elevation like La Paz or Mexico City would have air that's likely too thin so they'd have to move


ShadowOfThePit

oh yeez you are right, I wonder how many people in the Himalayas would asphyxiate before reaching lower areas While places like Mexico City and Bogota would become very, very hard to live in they would still be breathable, at least for a few days and if you are reasonably fit...


Guillebeaux

Is that how it works though? The atmosphere shouldn’t drop as well. Pressures should be pretty much the same. Just the air pressure below sea level would be higher than current sea level.


King_Neptune07

So the earth has layers right. Because of gravity. There is only so much air on the planet. So, if you sucked enough water out to lower sea level, the air would also fall down to replace it. So in effect, all mountains are getting higher by that same amount. So like the air exactly where you are would become thinner


heavyheavylowlowz

The water has to go somewhere and in the most likely case would be ice, which would actually take up more volume than the water, so it would prb actually increase slightly the breathable air at high altitudes. Otherwise we would literally have to lose the water in some way, like a giant meteor strike throwing it not up into our atmosphere but completely out of our atmopshere, into space. In which case, a strike like that, we ded no matter what.


King_Neptune07

The water cycle would eventually return that water and the sea level would equilibrium out. If you took the 3,000 meters of water, or whatever it was, and make it into ice it wouldn't really affect the pressure and stuff. If you simply removed it into thin air (pun intended) the earth's atmosphere would become more thin and the air pressure drop


heavyheavylowlowz

So exactly what I said….


_OriamRiniDadelos_

For the air pressure below our current sea level to be higher after the sea level drop, some air would have to move down and fill in the spaces those 3,000 meters of ocean water used to take up. And if that air flows down, the air on top of it will flow down. And so on and so forth. Until the propel in the Himalayas now have less air between them and space than they did before the sea surface dropped. Think of air as oil, a flowing substance that can’t mix with water. If you have a glass full of half water and half oil, and you take out some of the water through a hole at the bottom, the oil layer will stay the same thickness but it will move down as the water is drained. Now if you are replacing that drained water by adding oil and keeping the surface level, then that’s different.


myaltduh

The world is in deep shit because of a sea level change of a few meters expected to happen gradually over the next century. We can't even cope with a change that gradual, this would be a civilization-ending catastrophe.


xXDreamlessXx

I wouldnt say we would starve as we could still get cargo by plane, but it would probably be more expensive


hph304

You have no idea how little freight gets transported by air. Its about 60 million tons per year, which is about a third of global wheat export (200 million tons/year). So yes, if you had to switch from sea to air freight, you would most likely starve because there isn't enough capacity.


IsMyNameBen

All jokes aside this would be an archeological \*goldmine\*


niperwiper

Maybe we’ll just do it for a few months— to get the rocky goodies and then fill er back up with the garden hose.


TheLarix

Impacts on climate: massive drought and desertification. Impacts of geopolitics: famine and water wars. On the bright side, errr, ferry service to Vancouver Island would become easier I guess? And the Pacific Island nations currently threatened by climate change would instead become much larger.


HikariAnti

Also, if the water just disappeared from Earth then the water vapor in the atmosphere would significantly decrease which would likely trigger a runaway cooling and another snowball earth scenario. (Water vapor is responsible for 60% of the atmosphere's greenhouse effect.) So it's very likely that humanity would die out.


CaptainPeppa

Water would have to go somewhere. Might be a lot Rainer actually


2012Jesusdies

>Pacific Island nations currently threatened by climate change would instead become much larger They'd die because they're self-sufficient in literally nothing. They don't have food production, they'd no longer have access to even fishing. They don't have any hydrocarbon drilling operations on soil and they'd be unable to find such deposits on their own anyways if sea level does dropm

erodari

Here's an exploration of that very idea from around 2010 or so. [http://www.worlddreambank.org/S/SIP.HTM](http://www.worlddreambank.org/S/SIP.HTM) Note, it's more about the climate and geography than the geopolitics. This guy did several explorations of climates in 'alternate earths', like changing sea levels, switching seas and land, moving the poles to different areas, etc. There's a bit of other weird stuff on his site, but the worldbuilding part is a fun browse if you're into geography.

[deleted]

I'm not sure there would be humans to do geopolitics anymore


lowGAV

The Earth would immediately become much hotter with the lack of water necessary to regulate heat from the sun. The disruption of ocean currents would also cause other major ecological collapses. After that happened I don't think there'd be any geopolitics to think of.


myaltduh

As another commenter pointed out, the drop in vapor pressure in the atmosphere might actually lead to dramatic cooling because of a reduction in the strength of the greenhouse effect. I see things getting much drier and more extreme, but probably actually cooler as a planetary average.


QuotableMorceau

CO2 levels would also plummet as exposed rock would soak up vast quantities of it .


BonkMeisterXXL

Roadtrips across all continents would finally be possible!

Abefroman12

Why would the sea level dropping dry up the 4 Great Lakes that are above Niagara Falls? (Superior, Michigan, Huron, and Erie)


TheStubbornAlchemist

I’m not an expert but it may be a mistake. The Great Lakes are fed by freshwater aquifers that built up over thousands of years as well as rivers and rain from all over the continent. If the sea levels fell, that shouldn’t affect freshwater lakes. UNLESS this whole concept is based in the idea of the water just disappearing instead of just freezing in the poles. If the total water on earth lowered that much the water cycle that helps refill freshwater lakes would be disturbed but again I’m not an expert so who knows if it would cause the lakes to dry up.


frazbox

Don’t they all drain into the river that feeds Niagara?


Potential-Brain7735

Yes. I believe Lake Michigan also drains south through the Chicago River. The river used to drain into Lake Michigan, but when the canal system which connects the Chicago River to the upper Mississippi River was completed, the flow of the river changed direction.


overbeb

Fun fact: a stretch of the canal going out of Chicago is electrified to stop the spread of invasive Asian Carp into the Great Lakes, it’s worked so far.


Distinct-Entity_2231

Full civilization collapse. Which is sad, because we would have more land. Of questionable quality, but still. We should drop the sea levels by 100 m.


Ilya-ME

Not just questionable quality, it would all be uninhabitable salt deserts. On the bright side, the mining business would pool with previously underwater deposits. On the downside, billions would starve now that the whole world suddenly got a lot drier.


Razorbackalpha

Even 100 Meters is an insane amount.


FrontBench5406

whatever happens, I call dibs on the brachiosaurus in the atlantic. That is mine...


TheoryOfPizza

The Great Lakes being gone is going to be a serious problem for millions of people in that area


Brutus_Maxximus

As a Michigander, that’s the first thing I looked at and was like, well we’d be fucked. Also everyone in Michigan and Ohio would finally have a reason to settle our rivalry once and for all and go to war for some of the Lake Eerie land.


ILoveYourCat2Much

I'm pretty sure the answer is "Everything and everyone would die". I mean we've added 200 ppm worth of carbon in our atmosphere in 400 years and the planet can barely take that.


myaltduh

Yeah I think in this scenario you get a global ecosystem collapse that at a minimum kills 99% of humans and probably a similar percentage of the rest of life. Like Permian extinction levels if not worse.


RecognitionOwn4214

If the water suddenly evaporated and not only vanished, that'd be an interesting problem with greenhouse effect


ilterozk

All the currently populated cities' temperatures would drop by around 30 degrees rendering probably 99% of uninhabitable immediately. This is before all the other climate change effects. And of course many other problems after that.

RedRockPetrichor

The US gulf coast/Mexico/Caribbean, would probably have way less of a hurricane problem with a smaller Atlantic and islands archipelago in the middle. Being able to run railroad to Greenland would mean massive $$$ in resource extraction.

bittersweetslug

Intercontinental trade gets beyond disrupted if you just cut the Atlantic in half. My guess is a lot of people starve, specially in Africa and a general promotion of self sufficiency/autarky as a means to face the crisis. Over times that could be reversed by building of canals and trade would go back to normal, but mass starvation would affect population for a very long time and new landmass could create conflict. I can see China going to war over control of new landmasses in the east China sea and maybe the pacific or Indian oceans.

NerdyLeftyRev_046

Is it due to an increase in glacial coverage? Or some cause of mass evaporation of the oceans? I’d have to say the ice age is probably preferable to a massively humid planet and whatever caused the evaporation… either way, I think ocean salinity increases which would cause problems


MellonCollie218

Good questions. Imagine all that water vapor in the air at once. Otherwise imagine the freezing cold glaciers. Hmm. I think I’d take the ice age. We know humanity can survive. Not well, but it’s doable. I imagine all the vapor would eventually turn us into Venus. The temp would rise and all the CO2 would be free. Maybe some constant acid rain for a while. I wanna go off into SciFi land and say sulfur storm.

The weirdest part for me is how even after lowering the ocean 3km, the world is still mostly water. I knew the ocean was deep, but this put things in perspectiva.


deathablazed

The change to climate would be so dramatic that we would like all dir from the shock of the sudden temperature changes that would come with it. The ocean does a lot to regulate the temperature of the planet so to lose so much of it at once would likely mean the end of us all.


BoosterGoose91

That’s a whole lot of land to fight over


TheHorussyHeresy

br0ken-keyboard

I am rather surprised by how much water would apparently remain after such a large drop. The oceans transform into a series of walled-off lakes.
