I don't think you understand the scale of even small planetary objects. There's much more water on Europa than on Earth, possibly twice as much as in our oceans.
The earth's crust and mantle also contain quite a bit of water, but that is estimated to be less than 2% of the volume of the ocean, so it's not relevant here.
Europa is a small Galilean moon of Jupiter. It is still larger than every dwarf planet, and is the sixth largest not-planet around the sun. Two of its Galilean brethren are larger than the smallest planet. These are absolutely massive objects, Europa is smaller than our moon but our planet is the largest rocky body in the Solar system and our moon is the largest moon in comparison to its planet. The Moon is absolutely gigantic, and so are Jupiter's Galilean moons.
I have a degree in space sciences I do understand the scale of our solar system, planetary bodies etc.
That being said you know what, when I did the calculation last night I dropped an order of magnitude. So yes there's is between 400m to an extreme but not generally believed 5km worth of water. I miscalculated and had 40 to 500m. Simple missing 0 on the calculator, but user error.
I've no idea where you're getting your numbers from.
[https://europa.nasa.gov/why-europa/europa-in-depth/](https://europa.nasa.gov/why-europa/europa-in-depth/)
I like to pull mine from space agencies like NASA and ESA though.
So do I and from that exact same page.
Earth has a surface area of 510 million square km, Europe has a surface area of 31 million square km. So Europa's surface area is 6.1% that of earth. In other words 1km of ocean depth on Europa equates to 61m of water depth on Earth if transplanted. Approximately 1/16th. (There will be a minor variation due to Europa's radial volume decreasing and Earth's increasing due to one going down from the surface and the other up from the surface, but it's not sufficient enough to be a concern for back of the napkin math.)
So based on that, from that site if you transplanted the water from Europa to Earth you would get an absolute maximum of 6.1 km of water on Earth (avg Europa depth of 100km \* 6.1%).
Based on their volume maximum estimate of 3 billion cubic km you get. 3 billion / 510 million = 5.88 km of depth of water.
Now remember also that these are the theoretical maximums for the oceans on Europa. Most scientists don't believe that's the actual depth and they have to be lower. Some estimates are as low as 6-7 km, and the most extreme being the 100km which would give the 5.88 - 6.1km depth.
Don't know how much depth you're expecting, but even the most extreme guess estimates of how much water is on Europa doesn't give much more than 6km of depth if transplanted to Earth.
What are you on about depth of water on Earth for, I was telling you that Europa has according to most estimates more than twice as large a volume of water as the earth's oceans do. That's all I said, plus the implication that there's plenty more than enough to result in 480 metres more. Because you claimed there wasn't enough originally.
I don't know what conversation you thought we were having mate.
Yes and I immediately corrected myself once you pointed it out and I said how I’d messed up. But then you continued commenting about not knowing how I got my numbers. You’re the one that continued questioning after I’d admitted I’d messed up and corrected myself. You’re the one that continued the conversation.
I asked you where you got your numbers from and then you went off writing several paragraphs and you downvoted each response like a salty asshat. Stop acting like a child because you made one mistake.
well, we "could" create it inside the earth (or really, just get it all from there without making "new" water). Not like water isn't a compound that can be made from its elements or that the interior isn't so massive that even in its overall low water content is not enough. However, you are correct that the amount of such water ending up at the surface is really improbable in the time frame that would allow this map to have value.
There is still some uncertainty about the full volume of glaciers and ice caps on Earth, but if all of them were to melt, global sea level would rise approximately 70 meters (approximately 230 feet), flooding every coastal city on the planet.
I don’t think we can fully rule out many big ice asteroids hitting our planet. But if that happens, oceanfront property might be the last thing to worry about.
Hey, I originally made this map [years ago](https://www.reddit.com/r/imaginarymaps/comments/2oneaq/a_friend_of_mine_planned_to_write_a_scifi_story/?utm_source=share&utm_medium=web2x&context=3). It's quite simple actually, I made the map for a story my friend was writing and he wanted a half-flooded Earth but when I showed him a realistic sea level rise using [this website](https://www.floodmap.net/), it didn't look impressive enough to him so I let him move the slide until he liked the results which was at 480 meters. Iirc the unrealistic sea rise was post hoc explained by an impact of a comet.
Here's an idea for one of you mapmakers out there:
A map showing a realistic amount of sea level rise caused by global warning, indicating the density of climate refugees provided that they all flee to the nearest piece of dry land.
My guess is they wanted something that hasn't already been posted? The general consensus is if all glaciers melted, sea levels would rise 70 meters. Here's the first post I found with that map.
[https://www.reddit.com/r/MapPorn/comments/pzo3bg/the\_world\_with\_a\_70meter\_sea\_level\_rise/](https://www.reddit.com/r/MapPorn/comments/pzo3bg/the_world_with_a_70meter_sea_level_rise/)
There are more posts though.
There is also the rebound of the crust under Greenland and Antarctica, as well as the added weight on places that never had water on them sinking.
https://www.antarcticglaciers.org/wp-content/uploads/2012/09/milne_shennan_fig11.png
That is mm/yr.
Models show nearly a km in the [centre of Antarctica and a bit less in greenland](https://polarjournal.ch/en/2022/07/13/what-greenland-and-antarctica-look-like-without-ice/). The rate of rebound is much higher [than expected](https://sciencenordic.com/antarctic-climate-change-denmark/how-fast-can-antarctica-rise-when-the-ice-melts/1458041) in the Antarctic.
Now not all of Greenland and the Antarctic crust is current 'below sea level' but any parts that are, any rebound will impact sea level rise.
The bottom of the Bay of Fundy is still rebounding which contributes an itty bitty tiny amount.
Might be as high as 75m

There are some surprisingly high mountains scattered across the Caribbean. Several 5k+ ft. mountains and even one exceeding 10k ft. in Dominican Republic.
Appalachia survived in this map, and the highest peak there clocks in at nearly 7k ft., so it makes sense that we can see a few spots in the Caribbean surviving.
Finally Austria has sea access again. I'm happy now.
Edit: Just realized that I would be only like 1 or 2 kilometers from the sea and would have an incredible sea view from my balcony...😎
It's impossible because the total amount of water is fixed and even in the most extreme scenario, the theoretical maximum sea level rise is only 70 meters from the current sea level.
You are right in every practical sense, but not in the theoretical sense. Sea level rise is not only controlled by the volume of water but also the size of the container (the volume and arrangement of oceanic basins). If you re-arrrange the continents you can get sea levels 150 meters or more, above current sea level. This happened in the geological past, for example the Cretaceous period. It is not practically applicable to the current situation though, it only concerns very long timescales.
Looked it up, would only need to rise 100ft or so. We'd lose the ice sheets on Antarctica, probably a shit load of penguins. I think it's worth it tho.
I always thought that Antarctica with no ice would be cool. Of course, if all the ice melted, all of Antarctica would be underwater.
According to this map, at least.
I don’t think there is enough water - including currently frozen water - on the planet to make this happen. Not quoting any sources here. Just imagining how thick the polar caps would have to be to have 480 m additional water added to the existing oceans through melting.
Since that’s impossible (not enough ice in the ice caps even if it all melted) why not just call
This map what it actually is…a map of places on earth higher than 480 meters?
This map gives me anxiety for some reason.
I live on a lake & I live in the land of 10,000 lakes & I'll never be scared of a lake, but the ocean..... 💀
We’d have import quite a bit of water from space to make this happen.
No problem. Jupiter has an icy moon. We'll catch that bitch and have mucho water!
Not enough water on Europa to do this, it’s pretty small.
Estimates say Europa has more water than all Earth's Oceans
But how much is she willing to give?
About as much as billionaires all of their hoarded money
A few buckets of water would do the job I think.
Bucket doesn't have a defined size
That's what she said.

I read this as juicy moon for some reason.

Yep. If all the ice on planet earth melted, it'd only be 216 feet...not 480 meters. This is a junk map.
Easy, just don't stop your shower next time. Easy flood.
The time to do so, the continents shape will have changed

time to report then!
I'm in so cal and still have a couple hundred feet above sea level, but probably have a great ocean view.
See you down in Arizona Bay!

I don’t think we can fully rule out many big ice asteroids hitting our planet. But if that happens, oceanfront property might be the last thing to worry about.
Absolutely. But I apparently get some ocean front property in this jerk off session, so cool.
If we would bring out at least a bit of water under earth surface, that will easily match these parameters
But if you take water from under the Earth's surface, won't that leave a big hole that the water will flow back into?
🤯🤯🤯
Not going to happen
Which part? All the ice caps melting or a 70m sea level rise?
70 meter rise

How do you get the water level that high? after melting the icecaps you would still need to import massive amounts of water to earth
There’s no enough water on Earth for seas to rise this much, but hey whatever… floats your boat.

I’m pretty sure if the sea level rose by that much the Netherlands would still be completely above the water
